Two preset pots are available for adjustment of the input gain
for the left and right line levels of Input 1. The pots provide 16dB of gain
adjustment allowing an input range of +6dB to -10dB, reference 0dB
output. Fine level adjustment of Input 1 gain can be made by using the
Trim knob. The gain for Input 2 can be altered by adjusting two
potentiometers on the PCB ( See Section 3.3.9 ).

This button switches the module between receiving input 1
(with the switch released) and input 2 ( with the switch depressed, and
the red LED on ). Input 1 is fed from the XLR sockets and Input 2 is
situated on the D-Type Remote connector. If the optional internal gram
amplifier has been fitted, the turn-table should be connected to Input 2.

The signal from the dual stereo module can be routed to either
output A, output B, to both, or to neither. When a red LED is
illuminated, it indicates that the signal is routed to that output.

Dual Stereo LineThe HF ( treble ) and LF ( bass ) controls are
used to adjust the equalisation of the signal. The HF EQ boosts and cuts
the signal by ± 7.5dB at 8kHz. The LF EQ boosts and cuts the signal by
± 7.5dB at 100Hz.

With the EQ button depressed, the Equalisation described
above is switched into the signal path. The red LED illuminates when
the button is depressed. To bypass the EQ section, release the button.

The Balance knob is used to adjust the stereo image of the
signal on the stereo line input. Full anti-clockwise reduces the right
channel by -3dB and increases the left channel by +6dB. Full clockwise
reduces the left channel by -3dB and increases the right channel by
+6dB.
