Wheres the best place for the main processor? I'm designing a small semi-portable system and can't really determine if I should put the Driverack PA (dbx) on top of the amp rack or leave it in the other rack with the eq feedback etc etc. System is composed of two 21RU rolling racks. My only thought is if I put the unit with the amps, I save on cable lengths because ideally I want all connections to be extendable so that the two racks can be 15 feet apart. If I have to run from rack to rack and run highs mids and lows....yeah.... thanks.
