It is strongly recommended that the digital input termination is set to ON at all times.
Failure to do so may result in unreliable reception of digital input signals and/or crosstalk
between sources.
Input Gain Adjustment
For both analogue and digital sources the default input gain is zero, i.e. an input of 0dBu
results in a reading of 0dBu on the meters. However, to accommodate lower level sources
it is possible to introduce extra global input gain in 6dB steps. This gain applies to all
inputs and is controlled by the settings of switches 6 and 7 on Block 1 of the configuration
switches (found on the underside of the unit), according to the following table. Power
should be removed from the unit while making changes to the configuration switches and
reapplied once the changes are complete.

Note that the application of extra input gain reduces the maximum signal level permitted
before signal clipping occurs. The front panel CLIP indicator illuminates at the onset of
clipping, with extended illumination indicating that the input gain should be reduced and/
or the input signal levels attenuated.
