2:1 INPUT CHANNEL
NOTE: Use either the MIC or LINE input and NOT both together as this could
damage the MIC input circuitry or the equipment connected to it.
1 MIC INPUT Female XLR wired Pin 1 = Ground, Pin 2 = +ve phase. Pin 3 = -ve phase. The
channel may be driven with a low impedance balanced microphone. Input impedance
2kohm, gain range 15 to 60dB.
2 LINE INPUT Stereo 0.25" jack wired Tip = +ve phase, Ring = -ve phase, sleeve = ground. For
unbalanced use, connect a mono jack wired Tip = Signal, Sleeve = Ground.
3 GAIN control with 45dB range. Operates both LINE and MIC level inputs to ensure that
the input signal is at a suitable level to drive the channel. It determines the nominal
channel signal level by varying the pre-amp gain, preserving maximum headroom and
minimum noise without loading the input signal.
4 EQUALISATION A 3-band design comprising of:
4a High Frequency control is a shelving type with 16dB of boost/cut at 12kHz.
4b MID Frequency control is a peak/dip type with 16dB of boost/cut at 2kHz.
4c Low Frequency control is a shelving type with 16dB of boost/cut at 60Hz.
5 REV Turning this control clockwise sends the input channel signal to the 127 program
DIGITAL REVERB built in to the POWERHOUSE. The REV control is post-fade.
6 AUX This control is post-fade, like the REV control, but sends the input channel signal to
the AUX SEND jack. The AUX SEND would normally be connected to an effect.
7 MON The MON control is pre-fade, and turning it clockwise sends the input channel signal
to the MON SEND jack. The MON SEND would normally be connected to an amplifier
for foldback purposes.
8 PAN control allows a left-right stereo balance of the channel between the left and right
busses.
9 CLIP indicator. This LED illuminates whenever the signal approaches the maximum running
level. It monitors all stages within the input channel, and illuminates at 3dB prior to
clipping.
10 L-R/GRAPHIC button. When released, (L-R selected), the channel will be connected to the left and
right busses directly. To mix the input channel signal onto the left and right busses via
the GRAPHIC EQUALISER, depress this button.
11 FADER 60mm channel fader with 10dB of gain.
