The 1600-watt M1610-2 has two integrated 800-watt power amplifiers that can be assigned as stereo mains or mono main and mono monitor. Each amplifier is attached to an innovative master EQ section designed specifically for these new mixers. The master EQ has a 9-band graphic EQ with additional high and low shelving EQ's at either end of the frequency band. The nine graphic sliders are essentially all of the middle bands of a 15-band graphic EQ with the low and high frequency bands covered by separate shelving controls. This gives the user more control over the feedback-prone mid frequency bands; with high and low tone-shaping frequencies controlled by additional simple +/- 15 dB trim controls.
