Beginner’s Guide To PA Systems, Part 1: Basics

Mackie Thump

The Mackie Thump is a popular PA for DJs, with the speakers containing the amplifiers meaning there's no need to carry separate amps. Here the speakers are pictured with a small PA mixer.

Stuck understanding PA systems? Need to rent or buy one for your shows? Scared about plugging into or playing on a PA? Want to know why you need one at all, when you could take your home stereo speakers to the party and use those instead? If so, trust me - you’re not alone. This guide is here to help. I’ve helped lots of DJs like you, as well as many live acts, with getting the best from PA systems, and I’ve been doing it for a long time - even longer than the 15 years I’ve been DJing. In that time I have used lots of different PA systems, in places from small wedding venues right up to festivals with tens of thousands of people.

Furthermore, in my role as moderator of the Digital DJ Tips forum, I know full well how many DJs know very little about this important subject, judging by the number of questions asked about PAs. Which is why we decided it's high time to start unravelling some of the mysteries of PA systems from the point of view of DJs.

Just a word: What I’m offering here are views based on my own experience over that time. While I have not studied theoretical physics to prove what I believe, I have seen and heard enough to be pretty sure these guidelines are right. So experts might think differently about some of the minutae of what’s here, and who knows, on some points they might be right - but on the other hand I can’t remember a time that things haven’t work out well for me with PA systems, and I get a lot of compliments for my great sound. So having made that clear let's go!

What this series does and doesn’t cover

Line array

Looking for the low-down on this type of PA ( a 'line array' system)? Sorry, we're not going there...

This is a big subject, so let's narrow down what we're going to look at. This guide discusses low to mid-range PA systems, because these are the types of system that reader of this website are going to want to buy and are most likely to find themselves using. So I will not touch line array systems, for instance, as that is a whole different world and frankly if you’re DJing on that scale there will be audio engineers about to help anyway. (And if you do not know what a line array is, do not worry about it.) Also I am not touching big club gear in this guide. Big clubs present a very different environment to “simple venues”. The basics still apply, but you have to consider more things. Possibly we’ll cover these in a later guide or course.

Finally, I also get a lot of questions regarding “new stuff” like PA mixers that you can configure with iPads, active speakers that look like trumpets and so on. While we can’t cover all of this in a basic guide, the basics do apply in my experience. What’s more, if you familiarise yourself with these basics, you can more easy decide what is real innovation and what might in your case turn out to be only "for show"...

What is a PA? Why is it different from hi-fi system?

PA means “public address” and basically a PA is a system that is meant to provide a public (audience) with a constant quality of sound for a long period of time. Hence a PA system has some qualities that are different from common hi-fi-type equipment. We will cover the differences as we work through the guide.

Usually a PA system consists of three parts: A sound source (for DJs this is your sound card or controller “line” output), an amplification system, and a speaker system. But before we look more closely at each component of a PA system, let’s think first what we actually need from a PA system, as the needs of most DJs are different from a band or vocal presenter, and these needs will determine how our DJ PA is put together. It's time to look at some basic set-ups.

The most common DJ PA set-ups

1. The basic DJ set-up

So here’s a simple, basic set-up. (Note that in all these block diagrams, the sound travels from source [left] to output [right]. Also you can substitute “DJ controller” for “DJ mixer”, “DJ audio interface” etc - basically, it’s the master output from your DJ system.)

Basic PA set-up.

Basic DJ set-up.

This is the most basic set-up. Indeed, if you decide on active speakers (speakers with the amplifiers already built in) it can get even down to DJ controller and speakers! However the blocks are still there, it is just the routing with cables from the amplifier to your speakers has already been done for you by the manufacturer in the one cabinet.

2. The "enhanced" DJ set-up

Enhanced PA set-up

Enhanced DJ set-up.

The PA mixer is really no different to a DJ mixer in what it does (mix sound sources). Indeed, one might think that a PA mixer is not actually needed if you only use your controller. However, there is one big advantage to using a very small PA mixer, even in such a case: You can set up your DJ controller totally flat (ie all EQs are to middle and the master output is to 50%) and then do the sound check (see later in the series) from the PA mixer.

This way, you can still perform easily on your DJ controller and if you do not touch the PA mixer after the soundcheck everything should stay OK and sound will be good. That is why I recommend this set-up as enhanced over the above one.

3. The mobile DJ set-up

Mobile DJ set-up.

Mobile DJ set-up.

Again, in this set-up you can substitute the sound sources for other things; the microphone could be wireless, the iPod could be an iPad and of course it could also be a spare CD player or whatever... but the idea is the same. The point is that the PA mixer is the hub to joins all the connections from sound sources.

Now some DJ controllers do have microphone inputs, but most DJs prefer this kind of set-up as the talkover function on DJ controllers (the thing that ducks the music volume when the mic is in use) is in most cases not as good (if it exists at all) in a DJ controller, and a PA mixer will usually give you a greater level of control.

(Note that in established venues with DJ booths, often a pro DJ mixer either takes the place of the PA mixer here, feeding straight to the PA amps, or comes before the PA mixer, feeding into it, in which case the PA mixer is where you'll typically find the dedicated venue sound engineer lurking...)

However, there are times when you may be forced to use the microphone input on your DJ controller, which is when you might encounter...

4. The "mini mobile set-up"

Mini mobile set-up

Mini mobile set-up.

I know some mobile DJs who use this set-up instead. These DJs tend to be new and don’t yet have the money to buy a PA mixer (even though such mixers relatively cheap, as we’ll find out). Indeed, some DJ controllers even have another Aux in, where you can connect an iPod or CD player. The better your DJ controller, the more likely such a set-up is to deliver good results for you.

Next time...

So these are the very basic set-ups. I hope you can see that it is very simple if you think in these building blocks, there is no magic or voodoo about it. Nothing to be afraid of.

Where it all gets a bit more technical is in choosing a PA system, as there are lots of factors involved in choosing correctly. So in the next part we answer some common PA questions to help get you set..

  1. Chuck "DJ Vintage" van Eekelen says:

    Hey Terry,

    Good write-up, thanks.

    I wonder though about the PA Mixer in between the DJ setup and the Amp/Speaker combo. I have worked that way quite a few times in the past, but I always find a lot to be desired. Here are my concerns.

    1) More sh*t to carry :-). It is getting noticeably less fun to haul equipment around these day, I know: I am getting too old.
    2) Another mixer, even a small one, takes up more of the -in many cases- limited space. If I have my DJ coffin up on the stand, there isn't any room left for a mixer that I can easily reach.
    3) It's another cost factor. As you well know even a small, but decent PA mixer runs a couple of hundred bucks, which is money that can't go to other things
    4) I find it rather unpractical having to use two boards to do my gig. If you use a mic often or two as in my case, or you need a lot of aux possibilities, I think it is better to take that into account when buying your controller/mixer.
    5) I doubt that many DJ's can or want to sound out a room before they start playing. And sounding out a room decently, you'd need a (preferably 31-band) graphic EQ, or at the very least, a full parametric EQ. Both are hardly ever found on smaller and/or cheaper PA mixers. Besides the process takes quite some time and experienced ears if you are not using measuring equipment to do it right. Time you don't get paid for usually.

    I am mainly a mobile jock too. And I do own my own (Mackie HD) PA which sounds relatively flat (tested with RTA in a neutral room). 99 out of a 100 times it will sound good in the wedding/party venues I go too. The 1 time it doesn't, the problems are usually too big to overcome, like big reverb issues and "frequency-holes" due to shape or construction of a venue. Problems that can't be fixed by having just a simple PA mixer in between.

    It is a very handy option, as you said on forum before, if you have a multiple DJ setup. Cause all DJs can plug in on their own two channels on the PA mixer without the need to switch the amp/speaker over between the DJs sets.

    Again, as you said, we all have our own experience and workflow we used over the years. I noticed I am going leaner and leaner. Not so much the size of the gear, but the actual amount of boxes (flightcases) and cables I have to connect/disconnect every time. Less setup and breakdown time and less walks to and from the car have become a focal point in setting up my gear.

    Thanks again for the write-up, I see all the relevant questions on the forum too and there are many of them.


    • agree on the multiple band EQ.
      Better of with an EQ than a PA mixer. Easyer to carry and more powerfull to tune the sound.
      BUT, if you are not used to configure a multiple band EQ, you probably gonna make things worse than without an eq.

    • Is a 200 euro PA mixer behind an allen&heath xone mixer and before more than decent powered mobile sound system (qsc, rcf, turbosound, whateve) really going to sound better.

      • Chuck "DJ Vintage" van Eekelen says:

        Well, the point Terry was making is that with a dedicated PA mixer, you can set EQ for the room/PA combination. That way on your DJ mixer/controller you can use your EQ freely without having to worry about messing up the room EQ. I get that, although as stated, a multiband EQ would be a more preferable piece of outboard kit.

        And no, I'd dread to think someone had a 5-year old PA mixer from a less desirable brand, like say Behringer, and then hook up a 1200 dollar controller with top of line sound card built in. Yikes!


  2. Janne Huotari says:

    I have a really nice 5.1 with yamaha rx-v371 amp, and jamo speakers, which cost me a pretty penny. However i am having a bit of a latency (that i did not notice earlier, as my ear was not as developed as it is now), which is just annoying enough for me to not to be able to beatmatch by covering one ear with headphones.

    I found a lot of people with similar problems from the interwebs on various gear set ups, and some digital processing seemed to be the main reason for this in HI-FI amps, so, almost without exception, everyone was told to rethink their PA solution. Which is the situation i am now facing as well.

    I am considering of changing/upgrading, but i am not too sure of what direction i'd like to take. I absolutely love my 5.1, and it is so crisp when used with my full hd projector, so i would not really want to let it go.

    Any advice of what i should do? The amp+speakers cost me ~800 euros 2years back, and i am too fond of them to let them go.

    Would setting the DJ PA next to my current PA be a solution if i run them through PA mixer?

    I am with:
    S2 (currently all audio comes through S2 soundcard for me)
    Yamaha rx-v371 amp
    Jamo 5.1

    Thanks in advance,

    • Chuck "DJ Vintage" van Eekelen says:

      Point in case being made by Terry in his articel. Don't use Hifi amps to do PA stuff. The Jamo's ... borderline. You can use them on the road (depending on the type), but they are made for home use too really. Surround (5.x, 7.x) is something I wouldn't want in a PA anyway.

      Your best bet is to either rent a PA when you are playing out (you getter way better gear than you would usually purchase yourself, unless you play out two nights a week with your own gear) or to get a decent set of active speakers with or without subwoofer(s). I love active speakers, because you can never lose your amplifier through a defect and be left without sound, if push comes to shove you can finish the night on 1 speaker and perhaps your sub if you have one.

      Beware though! As has been stated here and on the forum time and time again ... when it comes to PA: You get what you pay for. There is no cheap shortcut to excellent sound at decent volumes.

      Greetinx and good luck with your decision,

      • Foldable disco says:

        True, no surround. Because surround systems use all sorts of enhancers and spatial algorithms to let your music sounds like a movie. That could be a reason of the latency you are experiencing. For example, just a clean 2.1 set up with 2 tops and a (mono)sub would do it. If you want more bass? Just add another sub.

        I use the Mackie Thump 15" tops with a 18" Mackie subwoofer, gives me all the power I need for now. The sound is maybe a little bit to clean, but we like it and it was in my budget.

    • Shenoizy says:

      I use/used a surround sound amp for my home DJ-set up without any problems. The key is to not use it in any kind of surround mode as that will introduce delay and unwanted processing into the sound. Most modern amps have a 'direct', 'pure' or 'multi-channel input' mode that will not add any further processing to the signal coming in. I personally use the multi-channel mode and feed my DJ mixer output to the surround rear channel speakers which are set up directly next to my mixing area. No audio delay, excellent sound quality and no extra cost.

  3. Dirty Disco Soundsystem says:

    At last! Thanks. Looking forward to next parts. If only this had appeared in Aug 2012 when I was about my first rig. Ah well...

  4. King of Snake says:

    Godsend Terry!
    just about to buy a new PA myself
    can't wait for the next articles...
    (was looking at peavy triflex II, any remarks on that?)


  5. Thanks for this post. It really applies to people who want to get into the DJ world who don't know a thing (like me). Thanks again.

  6. Thank you SO much for posting this!

  7. No PA Mixer but a DriveRack PX, always sound check with measurement mic.

  8. DJ Forced Hand says:

    This is a very good article on the basics of P.A.s. Certainly, if you're bringing your own sound someplace SOMEONE has to run it. Many people are tempted to EQ on-the-fly or "default to scared" and set their levels to "Noon" (just to play safe) and leave the settings there all night. You *can* get away with this about 85% of the time as long as the speakers are set up properly, they're angled to cross over in the middle of the target (dance) area, and they're a matched pair. Remember that the room sound changes when people start filling up the dance area and the temperature/humidity changes (due to people sweating) so make changes accordingly.

    Most (good) P.A. speakers will be "self-powered" or have the amplifier built into the case of the speaker. Don't forget that when you set your speakers to have them around 6' off the ground (whether you hang them or have them on speaker stands) but never have them on the same surface as the DJ gear, especially turntables, this is a good general rule. For added "Oomph!" get the sub-woofer not a larger speaker set to "Deep" mode. sub-woofers are a different creature and need to be set up a little differently.

  9. man i would just get a mixer with xlr using american audio dv2 mixer with the xlr outputs.......then just chain ur subs to the speakers through the outputs into the inputs of the subwoofers problem solved lol. no pa mixer etc. just have long enough xlr wires

  10. Great article! I was going to ask you a piece on just that!

    I started playing clubs here in Montreal and found that the sound quality was abysmal! On my last venue I was able to fiddle around with the setup to get the sound to 70% optimum but need a crash course of club PA systems.

    Here is the setup for my last club and the one I am most likely to play at again in the near future:

    - 6 monitors on the ceiling, one is the booth monitor for us DJs.
    - a "PA" speaker set (2x21" subs and 2x15" tops) for concerts
    - an Allen & Heath console, 16 tracks
    - A Numark iCDMIX 3 for CDJ/iPod/Mixer functions
    - a "speaker management" thingy from DBX, does crossover and limiter stuff
    - an EQ for the monitors that will go on the stage during shows.

    All speakers are active.

    Anyways, I put all the EQ in the middle, killed some mids from the A&E and things got acceptable but not optimum. My question is how to deal with the levels from the different components (controler, mixer, console, speakers, DBX thingy) ?

    Also is there a device or app to help me with improving the audio? Something that can hint at causes for bad sound?

    I got some names of soundmen from the local PA rental powerhouse so I might hire a guy to help me out one night.

    Anyways, can't wait for more of this, videos and a course would be great too.

    Carry on!

    • Here is the gear:

      DBX DriveRack 260
      DBX 231 EQ
      A&E MixWizard3 16:2
      ART HQ231 EQ

      What is this about using a MIC for soundcheck with my DriveRack?

      I just wanna play my CDs but bands play there hence the advanced gear. I'd just wanna pass the whole sound in my DJ Controller or at least have the gear in pass-thru mode as much as possible.

  11. Chuck "DJ Vintage" van Eekelen says:

    I would think it is the responsibility of the venue to provide a sound system that is optimised for their space. Doing that correctly is a rather complex matter. Changing one parameter usually introduces one or two other results.

    The best way to do it, these days, is to use pink/white noise and a RTA (Real Time Analyzer). Tweaking a PA like that can take a fair bit of time.

    One of the major issues with tweaking a PA is that the only time you can do it is in an empty house. The impact of the amount of people present is tremendous. I have heard rooms that sounded perfect "dry", i.e. no people in it and went to horrible as soon as it filled up about to half its capacity.

    The other way around too. I have played in a venue once where I played a tune in the afternoon (getting acquainted with the setup for the night) and just went "This suck, I am out of here". The resident DJ who was there showing me around just said "chill, wait for tonight". And indeed, as soon as the place filled up you could actually hear the sharp edges disappear and the sound settling in just right.

    As a mobile jock I don't usually bother with sounding out a room anymore. If your performance, entertainment value and musical selection are spot on and the gear you have is intrinsically good (meaning your PA doesn't do the harm itself by being of low sound quality), than I am sure nobody in the room is gonna remember if the lows or mids sat just right.

    We have a lot of cellars in the city where I live and playing in those it is impossible to get a really good sound (trust me, we have tried). Yet all visitors just chalk that up to venue appeal.

    My advice: get really good gear if you need to own your own or rent very good gear and don't worry too much about it. We are talking 100dB sound level venues, not whispered stageplay in a theater.

    And 5 minutes into that kind of sound attack, your ears just go "screw it ... I'll just give you the highlights" anyway.


    • LOL no. The venue I am at now had 60 people on opening night and maybe 6 of them danced and these people usually ALWAYS dance in other venues. The sound sucked so bad, like a bad mono sound from a toy of the 80s. No highs or lows, just distorted mids. I will try soon with my own source gear (A&E Xone:DX or Musiland Dragon soundcard) and see the impact the source has since I suspect crappy MP3 sound and bad DACs from the Numark CDJ.

      • Chuck "DJ Vintage" van Eekelen says:

        I am sympathetic to your situation. It sucks if you can't ignite the fire because the house PA sucks, but if they turn a deaf ear to your recommendations, I think I'd go hunt down another venue :-).


  12. DJ Forced Hand says:

    One more piece of advice for mixers: If you're going to run sound through a mixer, make sure you have enough channels to support the gear that's playing, and the gear that will be playing. You really don't want to be troubleshooting problems on a change-over. Any problems you have will kill a groove. Also, switching active channels while "live" adds stress to an already stressful moment. There are mixers available with 4 (or more) mono channels (one channel left, one channel right) or two stereo channels (one for each DJ rig), do yourself a favor and get one of these if you're not going to have one mixer/controller for the whole night.

    Also, do a sound check with 2 (or more controllers) before the set just to make sure one controller/mixer isn't louder/quieter than the other(s) ahead of time.

  13. Chuck "DJ Vintage" van Eekelen says:

    We used to have a Sony pre-amp in the old days. It had like one mic and 4 stereo line inputs. It sat in our 19" rack at 1U height. I believe it had 1/4" jacks for inputs (balanced). And you could just switch each channel on/off and control the volume with a rotary knob and it had a rotary master volume knob. So with the amps set to full you could control it all from that one unit.

    It was great for running multiple systems to the PA. We would have a DJ, a VJ and occasionally a karoake guy playing or sometimes a beamer sound and this way they could all plug in and off we went.

    PA mixer ARE predominantly made for microphone use, stereo line inputs are a bit of an add-on. If you run two XLR balanced lines into your PA mixer from your controller, you are actually running your controller output through the mixers MIC Pre-amps! This may have sound consequences as every mic pre-amp has it's own coloring and it means you have to keep your controller main out really low not to run the mixer input into the red. The PA circuit now has to amplify that signal back to a level that your controller could provide too.

    I know that many DJs will go "hey, I have XLR output, the mixer has XLR input, I'll go and use XLR-XLR cables, easy!". Unfortunately, not the best solution. Every mic channel on a PA also has 1/4" balanced jack LINE inputs. Use those and you'll bypass the mic preamp and can just send your full signal from the controller without redlining the PA mixer input.

    If I were to do a gig where more than one DJ was playing and/or where I felt the need to have a bit of 3-band EQ to slightly adjust to the room acoustics, I would get a simple analogue DJ mixer to handle that. The only drawback being that the DJ mixer will lack balanced inputs.

    Now if you run line level signals and you keep that extra mixer within 2-3 meter cable run you should be absolutely fine using regular (GOOD QUALITY!) RCA cables. And if you need to go further there are ways to make unbalanced RCA into balanced XLR and back the other way at the other end.

    To sum up the things I have said on the topic so far:

    * If the reason for the extra mixer is EQ-ing the room, better stick in a good graphic EQ before the PA.
    * If the extra mixer is needed to allow multiple DJs access to the PA, get a simple 4-6 channel analogue DJ mixer (depending on your needs of course).
    * If you have a PA mixer to go through (because it is already there for example) be sure you use one of its stereo inputs or use the line input on the mono channels.
    * If I were to have a setup like this, I'd get a 19" DJ mixer (maybe onle a few U high, not a full size) in a rack, mount a stereo graphic 31-band equalizer (19") below it and have a row of stereo RCA connections in a 19" patchpanel on the front. I'd make sure the door was lockable so once everything was connected and set up, NO ONE could touch the stuff and fiddle with it anymore :-).


  14. Thank you so much! This is a guide I've been needing for a while now, I've got my controller and my software (Mixtrack and Traktor) but PA systems have got me completely stumped. The guys down at my local GuitarCenter were trying to help me out but i honestly didn't know what I really needed


  15. scott cairo says:

    Good article.
    One thing I can add from my experience. Is that you cant beat an analogue fader between your sound card controller etc and the PA amps. It makes for a great way to kill the output if the digital kit throws a wobbler or indeed another dj throws one and outputs full line level. An anlogue fader is most unlikely to fail if you need to turn that off NOW.
    I use a wharfedale pro, its tiny has a mic input a headphone output, and is very handy to check your digital kit is actually outputting something useable before sending it out live.
    If anyones interested I always pack a little analogue mixer, ever since I was playing my Numark Mixtrack away the Lappy crashed and decided it wanted to send a Full level HORRIBLE noise to the rather expensive PA set up. And the only way to stop it was pull the plug at my end-which is not ideal. With a mixer in the chain I can just close the main fader. And have a emergency CD player hooked up to take over. Its these panicky moments when you see the advantage.

  16. This is a great beginner read. I am a part time new mobile DJ working since summer of 2011. I started that summer with a laptop a high powered computer speakers. After several gigs I started looking into the PA world. It did take some time reading to understand. My personal take was that the source is important. So I went with a Trakor S4. From there I have added powered speakers as audience has dictated. Now I have 4 behringer active 12s. Next I will be looking into a sub. The main thing for me was value. The price point on those were great. So the value is there. So I would say I have done okay with startup funds and knowledge.

    The next step for me is going to be finding the best power/sound - weight balance. I'm okay with the weight now of my current setup, but I would project as I increase work it would be best to not have to manage unnecessary weight.

    Anyone have suggestions on the best lightweight active PA?

    Thanks for info!


  17. DJ Vyshak Bhasi says:

    Hey , i have a doubt in this , In american audio vm4.1 traktor's user guide its written as we shouldn't connect the controller's output with any mixer , and they r telling to connect the balanced xlr outputs straight to the amp's xlr inputs ,If i connect it straight to the mixer will it get any prob?, or should i follow their user guide?

  18. Good Article. I found out that my DJ Controller was more powerful and flexible than my small PA Mixer. Here is my setup:
    Microphone (Shure Wireless - XLR) -> DJ Controller (Hercules RMX2 - XLR) -> DBX Driverack (instead of PA Mixer - XLR) --> Active (Powered) Speakers (JBL 615M and Sub)
    If I don't need my Subs (JBL 618), I don't use the DBX. It is overkill. Simple setups sometimes give you the best sound.

  19. Hi there,
    I have had a look at this and it is a huge volume of info and all really good and well presented/ still leaves my head swimming a bit with the technicality...but hey, I'm a blonde!
    What I am doing is not quite so advanced/ yet..but I want to be able to have music and voice (like karaoke, for example)without having a dedicated PA system. I have been told that I will damage or destroy ordinary speakers by putting live vocal through them, but since my audience is only five, and in a very small space I wonder if there is a way to prevent speaker damage..
    I clearly don't have a good working knowledge of audio systems in general, but I am pretty sure that technology is out there to do what I need...surely!?
    It's going to be me singing along to a backing track, driving a taxi, and the passengers(behind the standard perspex screen) being able to hear me clearly enough...As I said, I am not a professional, this is a one off and also I don't have bags of money to spend on this...
    Anything that you are able to suggest would be amazing at this point as all the 'experts' that I have asked have left me thinking that what I am doing is impossible!
    Thanks for taking the time if you have read this far!!!

  20. Is it necessary or better to have a PA Amplifier if the Speakers are self Amp'd like my JBLs are? Does it make it sound better or worse?

    Love these articles, I have been DJing for better part of 15 years now and its amazing to me that I am Always learning from every article. I am excited to utilize things I have learned to better my style, brand and company in 2014 and beyond!! Thank You!!

  21. KelComman2 says:

    Great Article...Thank you for taking the time to put this sort of info out there for people like myself...newbie and excited to start DJing.

    Anyone out there...I am looking into PA systems to go with a DJ Controller/Mixer - specifically, I like the DDJ-SX from Pioneer with the BEHRINGER EUROLIVE B815NEO or the B615D (which one would you or anyone recommend better of the two PAs B815NEO or the B615D?). I have been reading a bit about both, still undecided.

    The BEHRINGER EUROLIVEs mentioned above seem to come with mixers and amps already built-in (Active), would I need additional Mixers and/or Amplifiers to run them with the DJ controller?

    Thank you for your time and assistance.

    Best Regards,


  22. Hi,
    I'd like please to know which one better sound performance, to set it up in mono or stereo mode. As a beginner in this business I need know to more on how to enhance the performance of my mobile sound system. Right now my set up is, PA speakers in stereo and I have 4 15" and 4 18" sub-woofers 1000W each which is bridge and powered by one 2,500w crown amp and 6,000W beiranger amp. All of my power amps are switch mode power supply, I am asking advise if do I need to replace it with a linear power supply or just use it for a while. Your advise it will be appreciated, thanks!

    Best regards,

As a beginner in this business I need to know more on how to enhance the performance of my mobile sound system. Right now my unit composed of 10-15" 1,000w PA speakers in stereo, 4 -15" sub-woofer and 4-18" sub-woofers rated 1000W each with bridge configuration sub-woofers are driven by one 2,500w crown amp and one 6,000W beiranger amp and for PA I had a 3,000W beirenger and for tweeters it driven by 1,600W Geam Sound amp. All amps power supply are switch mode, I am asking your helpful advise if do I need to replace it with a linear power supply or I'll just continue using it for a while. Your advise regarding this matter will be highly appreciated, thanks!
