Configuring the digital surround controller without a computer

Setting up sources
This section explains how to use Gain/Sub mode to set up the
sources connected to the digital surround controller, and
configure them to suit your other equipment.
You can also adjust the subwoofer crossover frequency to suit
the subwoofers in your system.
To turn on Gain/Sub mode
●
Put the digital surround controller into standby by pressing
Off
(front panel or remote).
●
Press and hold the
Mute
key on the front panel for at least
five seconds.
The display shows:
Gain/Sub On
The 561 will then return to standby with Gain/Sub mode turned
on.
Gain/Sub mode adds three extra options to the DSP parameter
menus:
Gain
,
Xover
, and
Sine
.
To turn off Gain/Sub mode
●
Repeat the above procedure until
the display shows:
Gain/Sub Off
To adjust the sensitivity of analogue
sources
The 561 contains a very high-quality Analogue to Digital
Converter (ADC) which allows analogue sources to take
advantage of our unique surround modes and the highly
transparent DSP volume control.
To obtain the best signal-to-noise ratio for your analogue inputs
you can adjust the sensitivity of each input to give the highest
level which does not produce clipping. Clipping in the ADC can
sound very unpleasant and can occur at any output volume
level.
For each analogue input, the sensitivity should be set using the
loudest passages in the loudest source material available, such
as the commercials on a TV channel. While setting the sensitivity
you can choose any surrround mode or volume level, as these
do not affect the input level.
