What are you using to send power for testing? Currently working on some 300 ip's and tired of buying the whole boards. Thanks!

Thx for sharing! Keep it up ! Cheers from Sweden

When i worked in live sound we always overspecified the rigs we put out. It was all JBL speakers, 4-way active, HH VX series amplification. The rig was essentially in 2KW 'modules', a module being 2 off 2x18" reflex folded horn bass, 2x10" horn loaded mid, 2" upper mid compression driver, 1" compression top. If a venue demanded, say, 8KW we would take 16KW and run the whole thing at -6dB soft limit with -3dB hard limit. Zero stress on any component, zero power compression and sound of an extremely high quality. No going home with ringing ears, never once blew a driver and the punters always loved it. Sadly jn these days of line arrays and DSP a lot of this dark art of sound reinforcement seems to have been lost. Great video

Unprepared mess.

Very informative. I currently run 2 active sets in London, 1 is what you would describe as a PA set using double 12” subs with 15” tops, the other double 18” subs with horn loaded tops. I’m considering a passive set up for larger outdoor events so this was very useful information for me. Subscribed and looking forward to more content from you. Thank you.

One of the best and well explained audio engineering video on KZbin! I always watch these videos thanks man ❤

It's heavier bigger and better. Job done. This looks like the basement in my house.

Nice set up....always talk to the DJ's who use my set up about gain control good practice never go into the RED!!! Do you ever do gig logs!!?

Dude this was SUPER useful, esp the section about marquee set up and was enough power. Have some outdoor events and judging how much sound we need is always tough one Sick great video

Those are not large scale since it is not a line array that is a stacked medium scale sound system, Difference between the large scale vs a DJ PA System is that large scale is a line array and has a lot stuff then a standard DJ PA System, This is a medium stacked scale Sound system which it is Bigger Large DJ PA System that has much stuff that large scale has than a Standard DJ PA System that has less. My Sound System has A lot of speakers that are Big like larger Sound Systems that Large scale does have too and it is also an DJ PA system so it is in mixed of those.

This is a small DJ system....

Really interesting. I was interested in the input power: you said that a 13A supply won't cut it. How does this work in the non-commercial sector, let's call them free parties. Some of the rigs I've seen are at least as large as the one you show here, if not larger. Yet the generators they use just appear to be little things from hire shops. Can they really give enough output?

thank you, thank you, thank you

I thought you were showing the system in the picture as an example for "DJ PA"... "Large scale PA system" is line arrays in stadiums, not this. Don't get me wrong, I'm not saying this PA is bad, it's just.. if you're calling this "large scale" then what do you call a K1 rig?

Very informative Thanks

Good information. Could you do another on how the distro is used and connected?

Active speakers are great for mobile DJing due to ease of setup. However the plate amps in active speakers tend to fail overtime if it’s pushed hard. For permanent installation setups, passive speakers are king regardless of system size even if it’s just 2 12 inch speakers and a 15 inch subwoofer.

Inductors and resistors in parallel just to produce the required ratings from commercially available components. Im not sure the limiter circuits use MOSFETs. Aren't they TRIACs?

What is the model of the Presonus Mixer that you're using?

loved that, very interesting from a small fry musician.

Btw thats not a snare its the floor tom, the snare is on the opposite side, other than that, great video!

Since the amplifiers already have DSP processors built in, why it's better (or necessary) to use an external DSP rack?

My back has just twinged!

As far as clipping and speaker damage, the clipped material sends disproportionately more power to the tweeter (and possibly midrange) and those drivers tend to get stressed more (although by this point it sounds horrible to your ears) than turning up a more powerful amplifier the same gain level that doesn't clip. Different types of music have different frequency content and also power handling (in a multi driver system) is band dependent, meaning a speaker can't handle as much at 2kHz (tweeter), as it can at 300 Hz (woofer), but it is usually more sensitive up there so it doesn't have to. It doesn't tend to be the woofers that go, unless the power (clean or clipped) exceeds their continuous rating for long enough. Because of the inductance of a speaker, it doesn't see DC at any frequencies in the audio band (people think it's like connecting a battery to the speaker, then reversing the polarity, then reversing it again, causing the speaker to sit at minimum impedance for extended time).

As far as electricity use, using more subwoofers at lower volume is actually energy saver compared to cranking one or two subs hard.

Your videos are great! Raw format is nice, there is no need to edit your videos, thats how good you are in explaining everything, keep it simple and... real. Besides, there is already a lot of often overedited videos on KZbin :) So, im subscriber from day 1 :) Keep them coming. Cheers!

Interesting. Thanks.

Great content! Thanks and keep it up 💪

mm nice monitor set man 😁

Was thinking about getting some FBT speakers any opinions on them from anything you’ve heard about them. Love love the videos keep them coming 👍

Great video. Very well explained mate. Keep up the good work. 😎👍

What type of mixer is this bro?

Watching from Philippines 👍

This was really helpful, thanks. Even though you delivered it off-the-cuff you still managed to cover a bunch of useful info I didn't know.

The classic Crown and Void combo ... can't go wrong with that pair up!

Stick 3ph 32 up that rack 32 sph is not enough by a long way

The main differences between DJ and Large Scale PA are: the mixing board, amount of input channels, and monitors. Not the power.

so where do you get 32amps mains into the setup ?

In germany it often goes from speakers on stick to flown speakers but really quickly towards small line arrays. Your really rarely see tops like that.

nice video, first i thought the system you show is the dj system since on large scale events you see kinda this system as dj monitor for real xD but when you said you made 700 people happy with this setup i was wondering what kind of event this was? i can't belive this is enough preasure in the last row for a 700 person techno event (maybe indoor in a smaller room) but maybe for pop or something?

I need this in my apartment

Thanks for this, that was great, amp racks have always interested me , to know what drives what and how the audio and the power is fed in, this video is a real education

12,000 watts through a single 16 amp CEE, I don't think so pal.

I've got a home-build PA coming along, 2 Subs, 2 kick boxes and 2 tops, I've been wondering about where in the chain to put the limiter because atm my signal in goes straight to my processor (no limiter/compress control). Would it come before or after this? I noticed your bass amp dials are maxed out, do you have the signal attenuated back in the processor to avoid clients fiddling with setups? Appreciate this vid, have subbed.

Easy answer: your needs dictates your setup. People rush to get the biggest speakers, biggest amps and call that good. But that's not even scratching the surface of what you should know while looking. DJing is more so for small venues, once and awhile you'll get a bigger venue show, but rare in the USA since everyone has their own house stuff. Pa= portable audio. But DJing rigs are more portable than PA systems 😅😂 makes sense! Lol Always wear ear protection! I'm stuck with tinnitus

crown macro tech 😍

I don’t understand what’s so special about a driverack, can’t you make all those adjustments in a digital mixer? It seems completely unnecessary.

All that talk about watts ... the only specs that matter is spl

The biggest danger to speakers in this video is those horrendous Crown amps. I have worked both cinema and live sound for over 35 years, did a lot of bench repairs on amplifiers and Crowns were on that bench 7 to one compared to ALL OTHER BRANDS COMBINED. They are unstable, unreliable, prone to DC faults to the speakers, and despite all the hype, don't sound that clean or good compared to most of the competition. The most robust and reliable amps I have ever used are QSC. They have very clean and tight sound, are super reliable, and QSC's support is the best in the industry. Out of over 2,000 QSC amps I installed or encountered in locations I serviced, I have had only 5 failures, and NONE of those ever damaged speakers or input sources, unlike Crown where I had replaced countless blown drivers, (a few actually went up in flames) and more than a few cinema processors and mixers. No, I do not work for QSC nor am I a QSC dealer. Just an independent tech who has done a lot of audio work.

The biggest sound systems I've ever ran across are in the Philippines, their competition sound systems with 40 or more 18 or 21 inch folded horn subwoofers! And usually 20 or more midrange and high end horn loaded aswell :D Often running on over 200kW amp power. Pretty wild :) would love to experience that IRL sometime! It looks pretty menacing on video, hehe. Im into some pro audio myself too, fun to mess around with. I don't do anything on professional level, just some personal loud music. About a 5kW system with 2 horn loaded 15" subs and a pair of ultra -high excursion 15"s with some serious power handling aswell to really take care of everything down to 20hz, and a pair of 15 inch midbass and some compression driver tweets. Everything is based around 15's and it works absolutely fine! It sounds just as good as a system wirh different size drivers., its absolutely wild at home, shakes the whole house aparr :) we get 3 phase supplies here in my country, so i have no problems running that at home. I can run much larger stuff if i want to, but this is more than enough to satisfy my own desire for loud bass haha! I would call my sound system a "medium" sized PA system, between a DJ system, and between a smaller large-scale system. Lovely video, you brought up lots of good and useful things! Thumbs up :)
