Troubleshooting Gain Structure

If the procedure followed to this point does not give satisfactory results, follow the appro-
priate adjustment sequence below:

If channel clipping occurs

If the signal is clipping or producing audible distortion, the gain is too high. Reduce the
Input Gain/Trim Control (rear panel) by turning it counterclockwise until clipping does not
occur. Also make sure that the new setting of the gain control offers a usable control range
between the 9 oʼclock and 2 oʼclock positions on the front panel volume control knob.

If channel volume is too low

If a channel must be set above the 2 oʼclock position to provide adequate volume, the input
gain setting is too low. Turn the volume control knob to the 1 oʼclock position and increase
the input gain by turning the input gain/trim control clockwise until clipping occurs, or VU
meter is over 0 VU. Then adjust the gain to a setting just below the clipping level.

If channel volume is too high

If a channel is not clipping but must be set below the 9 oʼclock position to achieve the proper
volume level, the input gain control setting is too high. Reduce the Input Gain/Trim Control
by turning it counterclockwise. Set the volume control knob to the 9 oʼclock position and
continue to adjust the gain control until the desired volume level is achieved.
