P.A. power amplifiers

[Steelpriest]

We have a new P.A. amp in our rehearsal room, our ex-singer/keyboardist took the old one with him so we needed a new one immediately. We purchased a no-name affordable one, that is very solid and old-fashioned technically. It has a toroidal transformer and is very weighty. I checked another amp I borrowed recently and found that seemingly also P.A. amps have specific and different sounds of their own. Is it just me, or my imagination or does a solid state power amp really have effect on the overall sound that much? IMO a power amp should just power the sound (amplify it) and not add sound characteristics... any comments? I have to add I am very happy with the new purchase, but I really had to reduce bass on the mixing console, or to be precise on the sum graphic EQ.

yes they do sound different. just like an guitar amp sort of but not as much. the cheaper the amp the less quality of sound and usualy less durable. amps gain structures vary a bit also.

Both Tapco and QSC are quality devices. QSC is a little more at home with power amps then Tapco with Tapco being the sun of Tascam. The DBX is also a quality device and should serve you well. Either way consider running the amp bridged mono for subs in the amp will run much more efficiently and your don't need stereo for subs. Also as you probably know you need to use a good large gauge cable for all that power. I'd use nothing smaller then 12 Ga. with less then a 100' run.
