The AUX SND 1 output is connected to a digital signal processor for reverb and other effects, and the stereo output from the signal processor is returned to the AUX RTN 1 connectors. The AUX 1 controls can thus be used to set up the required effect mix..The AUX 2 controls are used to provide a separate monitor mix for the performers on stage. The AUX SND 2 output is therefore connected to a power amplifier driving the on-stage monitor speaker system. The main house power amplifier/speaker system can be fed by the ST OUT L and R outputs. In this system a tape player is connected to the AUX RTN 2 inputs to provide background music during intermission or recorded accompaniment for the performance. 6- BLOCK DIAGRAM -J CH o z o u DIMENSIONS 37 (1-7/16") UNIT = mm (inch) -7- SPECIFICATIONS Frequency Response +1, -2 dB, 20 Hz — 20 kHz, 10 kohms, 0 dB (ST OUT) +1, -2 dB, 20 Hz — 20 kHz, 10 kohms, -10 dB (AUX SND 1, 2), (SUB OUT) Total Harmonic Distortion Less than 0.05%, 20 Hz — 20 kHz, 10 kohms, +10 dB Hum & Noise* (20 Hz — 20 kHz, Rs = 150 ohms, CH1, 2 Gain max.) -122dB(CH1, 2) equivalent input noise. -90 dB (ST OUT) residual output noise. -76 dB (76 dB S/N) at ST OUT, Master fader nominal, all channel faders minimum. -72 dB (72 dB S/N) at ST OUT, Master fader nominal, channel 1, 2 faders nominal. -88 dB (78 dB S/N) at AUX SND, all channel AUX controls minimum. -82 dB (72 dB S/N) at channel 1, 2 faders nominal, AUX controls nominal.
