Setting up sources
This section explains how to use the Sine/Sub/Sens controls to
adjust the sensitivity of the analogue sources.
To adjust the sensitivity of a source
To obtain the best signal-to-noise ratio for each analogue source
you can adjust its sensitivity to give the highest level that does not
produce clipping.
•Select the source you want to adjust, with loud source material
playing.
•Display the Sine/Sub/Sens controls as described above.
•Press Sens- or Sens+ to decrease or increase the sensitivity.
The display shows the current sensitivity and the peak level; for
example:
Sine -Xover+ -Sens.+
TV 1.4V Peak -3
You can adjust the sensitivity between 0.7, 1.0, 1.4, 2.0, and 2.8V
(least sensitive).
If the sensitivity is set too high the input will clip the loudest
passages, and the peak will be 0dB.
The display shows, for example:
Sine -Xover+ -Sens.+
TV 2.0V Clip -0
In this case reduce the sensitivity by selecting a higher number.
If you have selected a digital source you cannot adjust the
sensitivity and the display shows, for example:
Sine -Xover+ -Sens.+
