Power LED
— Lights green to indicate that the BUC 102
has power.

Left input channel audio gain control
— Adjusts the
audio input gain of the stereo left channel. The gain is
adjusted by rotating the screw and the adjustment range is
from mute (fully counterclockwise) to +20dB (fully
clockwise). See

under Rear Panel Features and Cabling in
this chapter. See note below.

Right input channel audio gain control
— Adjusts the
audio input gain of the stereo right channel. The gain is
adjusted by rotating the screw and the adjustment range is
from mute (fully counterclockwise) to +20dB (fully
clockwise). See
5
under Rear Panel Features and Cabling in
this chapter. See note below.
Unity gain (0dB) for both channels is around the
12 o’clock (vertical) position with the pot adjustment
screws vertically aligned with the indicator dots, as
shown here.

The pots of the BUC 102 are set precisely to unity gain
at the factory. Once a pot adjustment screw is turned,
test equipment will be required to accurately reset the
pot to unity gain.
