Setting the analog input level
The SP31 allows you to adjust the input level to the
analog-to-digital converter to achieve the best possible
signal-to-noise ratio.
If the ADC input level is set too high clipping will occur
on loud signals, causing distortion. The SP31 detects this
and displays a SET ADC warning on the front panel and
on-screen displays.

or buttons on the remote control to highlight

the front panel or the SELECT button on the remote
control to select the required option.

the or buttons on the remote control to reduce the
level until the SET ADC warning stops flashing on the
loudest passages.
