14. CHANNEL INPUTS 1-6
These balanced three-pin XLR connectors accept a standard microphone cable or other low impedance
signal. Optional transformer balanced inputs are also available.
15. INPUT GAIN CONTROLS
These knobs provide continuous control of the input levels for each of the six input channels. When adjusting
the input gain, make certain that the levels are not set too high, or distortion will result.
The approximate levels for these controls are as follows:
MIC mic level (-50dB ~ -60dB)
MIC ATT instrument level (-30dB ~ -50dB)
AUX line level (-20dB ~ -30dB)
