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:

TV	1.4V Peak -3

Sine -Xover+ -Sens.+

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:

TV 2.0V Clip -0

Sine -Xover+ -Sens.+

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:

DVD Not Analogue

Sine -Xover+ -Sens.+
