话题: How to hook up multiple amps

由于该帖子已年深日久,可能包含陈旧过时或描述错误的信息。

Can someone help me by explaining how to hook up more than one amp to one mixing board. My subs have built in crossovers but I never tried hooking up two amps at once. I use the QSC PLX and MMX series and have JBL 12's and Cerwin Vega 15 subs. QSC PLX is a 3000 watt max bridged. RMX is rated at 2450.

Thanks.

I never tried going with multiple amps.

There are diferent ways to hook up multiple amps.

1. cascade mode: I believe the QSC amps have inpunt and pass thru lines on the back, what you need to do, if your subs have xover for low freq. then just hook up your console to the first amp, then conect XLR cables from pass thru of that amp and hook it up to the input on the next amp and so on. You have to be sure the passthru line of your amps are not only high pass thru, that pass thru line has to be full rage so the low freq. on the subs can be set.

2. Using a xover: this is the safest and more versatile way for me, I can recomend the DBX 234 XL, it is a 3 way stereo xover and is not expensive ( arround $250.00 ) the steps to hook it up are very simple and logical, you have low, mid low, mid high inpunts and aoutputs on the Xvover, if you decide for this option, sned me an e-mail and I will explain step by step how you can hook it up.

Hope this helps.

here is a link for the Xover http://www.dbxpro.com/234XL/234XL.php

I personally haven't seen any pass thru on the plx's......so easiest & cheapest way is to get some y's.

Are u goin straight outta your mixing board, pc or sound board??

if your going to get a crossover...save money & get the Behringer:

if u want to spend a hair more & don't care about keeping stereo (which u shouldn't most likely with the different rooms) get this half crossover half eq

Its all how u use it....alot of people choose to use high end equipment because they don't have much knowledge on how to use it....higher end equipment can handle much more of a beating....but u should never beat on any of your equipment.....thats where the knowledge part kicks in. Thats what it comes down to to. But dbx is great.....but your budget is what matters.
