Apologies if this isn't the place, I have questions about a minimalist live sound setup designed to do double duty as an outdoor sound system for projected movie nights. room is small, 20 people maximum. outdoor area is probably 50 ft by 50 ft and has access to mains power. I'd like to set up something where one or two vocalists can be amped to be heard above a bunch of acoustic guitars and hand drums, occasionally with a prerecorded backing track piped through instead. A karaoke-esque thing. I'd also like to use this for a stereo setup outside to provide quality audio for a projector in a large backyard. My thoughts so far are to use something like: Behringer q502 or q502usb - https://www.google.com/url?sa=t&sou...s4jIocNskFYfXWG 8" passive 100w rms pa speakers - Rockville SPG84 8" Inch Passive 400w DJ PA Speaker ABS Lightweight Cabinet 4 Ohm https://www.amazon.com/Rockville-SP...=8-3&th=1&psc=1 and an amp - which is where I need the most help. Given the small size of the room would a small class D amp suffice? Something like this? https://www.amazon.com/gp/aw/d/B07MV3PMZD/ref=cm_cr_arp_mb_bdcrb_top?ie=UTF8 Thanks peoples. Sorry if I'm unclear. r.y.f.s.o. fucked around with this message at 16:23 on Jun 10, 2019 |

Brute Squad posted:You'll need more power than that amp. Something that can push at least 400w/channel at 4ohms. The idea being that when you overdrive an amp you add distortion to the output, which does more damage to speakers in the long run than just overdriving them. Thanks for the information. After discussing it with my roomie (who is paying for everything, his house so his need, I'm just advising) he wanted an all-in-one on the smaller side of things, preferably with a wheeled carrying case and 4 or 5 inputs. I found a Kustom Profile System One on CL nearby for $200 and picked it up to see if it fit the bill. Over in the Amp thread someone gave their blessing to the Kustom PA so I went for it. It works fine but the sound is a all mids and highs - given the small drivers in the cabs it's not hard to guess why. I've been looking at adding a small sub to the system - it lacks a sub output, so I need to add it some other way. One option is to utilize the line level outputs it has, technically designed for effects loops or output-to-recording purposes - but I'd have to use a separate volume control for the bass which is sub optimal. Heh. Is it possible to split the speaker-out 1/4 connections, and have one of the lines from each output go to the high-level inputs on a powered sub? Am I right in reading that subs can be configured to deal with the high power output of the amp, step it down to something useful, then use an internal crossover to simply use the lower frequencies on it's own internal amp?

Grand Prize Winner posted:You do not want to plug speaker-level signal into a line-in socket on an active speaker. Once you've messed around with it and got levels you like, take a pen or a sharpie and mark them on the mixer and then you won't have to futz with the settings too much. I didn't mean speaker (amped) to line-in - I meant speaker level to high-level input - based on what I read, those are designed to handle the amped signal even if the sub is itself amped. I looked at the insert ring / tip in / out (or whatever it is) method too though - will that be affected by the main volume control? It would be nice to have the sub level on the same level control as the rest.

Yeah I was looking at cheap HT subs - I'm putting this together for my friend who is working with a budget so cheap is key. I think I've got a handle on it now, I appreciate your help.
