Multiple amps in same freq band

 

My rig is 5 way but runs off 3 amps mostly.  Subs off 1 amp, kicks off another amp, mids off ch1 of amp 3, tops and supertweeters (passively crossed) off ch2 of amp 3.

 

If you you mean, how would you go about adding another amp to drive 4 more bass bins in addition to the 4 you already have (as an example number) you could either get a Y split cable out of the relevant crossover output and connect it to both of the amps, or the more usual way is to link out of the first amp, into the second amp.

 

Most amps have 2 'inputs' for each channel, usually a combination of xlr and TRS jack.  These are in fact both inputs and outputs as they are simply wired in parallel.  You could go from x-over output to XLR input, then link out with a TRS jack lead to the jack socket of the next amp.  In relation to Spesh's post above, you don't have to go XLR-->jack, jack-->XLR, etc as they are not designated in or out, so you would prob go XLR-->XLR then jack to jack, then xlr's again as the cables are easier to come by/make up and are more versatile to have in your cable box.

 

So if you have a big rack of amps all doing the same job you just put 1 signal in at the top and then daisy chain down the rack as you would when connecting speakers in parallel.  Some manufacturers (QSC for 1) route the ch1 inputs to the ch2 inputs when in parallel and bridge mode so you have a full set of connectors available to you.

 

xover bass - into one amp then linked from that amp to another

 

and so on?
