Stereo Power Amps: different signals to different speakers?

#1 Post by ryansalmond »

I want to run both a guitar signal, and a vocal signal through a power amp. Can one stereo power amp send the guitar signal to a guitar cab and the vocal signal to a PA cab? or will I end up with both signals going to both cabinets.

Thanks.

I will be plugging into a PreSonus Firestudio for the vocal preamp and a Sansamp California for the guitar preamp. I was thinking 8 ohm cabinets, but that's a variable as I haven't built them yet. I'm just wondering if two signals can be kept totally separate by a stereo power amp.

As long as it has separate inputs for each channel. But, we need more info.
If it's too loud, you're even older than me! Like me.

I was thinking one of these: http://www.qscaudio.com/products/amps/rmx/rmx.htm
into an omni212 (guitar, no tweeter) and two daisy-chained wedgehorns (vocals)

Usually you'd have at least a small mixer in the middle there. What are you trying to accomplish?

+1 : add a small mixer before the amp. Pan guitar to one side, and vocals to the other side. Just make sure they are always panned appropriately before you turn on/up. You get much more control using a mixer instead of just plugging strain in.
