AUDIO CONFIGURATIONS:
The source and destination audio equipment must be evaluated to determine if they are Balanced or Unbalanced. After determination is made, refer to the drawings provided to select the proper audio configuration. The outputs can be any combination of balanced or unbalanced.

The input to output level comparison provided in the figures above, assumes the outputs are terminated into a 600Ω load.
FRONT PANEL:
The adjustments and indicators on the front panel (Figure 3) can be accessed through the slots provided in the frame in which the
Gain control for the right channel is achieved by adjustments to S01and R012. Gain control for the left channel is achieved by adjustments to S901and R912. S01 and S901 provide gain adjustment in increments of 6dB, while R012 and R912 provide fine adjustments of +/- 3dB. The positions of S01 make the following adjustments to the gain level of the circuit
| 1 2 3 | 4 56 |
