Peak indicatorPK The input signal is monitored at several points throughout the channel.These points are t
14、he mic preamp,the EQ stage and the fader stage.Overload at any of these stages will cause the red peak-LED to light. The channel gain should reduced if this occurs. Signal level LEDs These three LEDs light up at +8yellow,0green,and -6 dBgreen.This level range -6 to +8 is the optimum operating range.
