Why waste time and effort wiring up separate units in an install when you can get a compact rackmount unit that lets you set up the mixer, gates, compressors, EQs and limiters on a PC, leaving the finished system tamperproof and sounding perfect?
The DR66 is really simple to set up, can be controlled in many different ways (wall plates, touchscreens, timed events, front panel keys etc) and unlike some alternatives, it's well within budget for everyday installations.
