Con guring your C31 pre-ampli er
Introduction
The C31 allows you to customise various features of the ampli er to t your system. Use this diagram
to help you navigate through the available con guration options.
In the diagram below, the ENTER and SELECT buttons from the front panel are represented by the
symbols and respectively.
The control knob is shown as .
Adjusting listening settings
Normally, the display shows the current volume and the control knob is used to adjust this.
Press SELECT once to enter the con guration menu, then press it
repeatedly to cycle through the menu items. When you have found
the setting that you wish to adjust (the setting is shown on the
display), it can be adjusted by using the control knob. Press ENTER
to store the change you have made and return to default (volume)
mode, or press SELECT again to move to the next setting.
Note that the menu will time-out after a short period of inactivity,
with the display reverting to the current volume.
The following items are available for adjustment:
Volume Resolution – There are three volume-display options to
chose from: ‘Standard’, ‘Fine’ or ‘Reference’. Standard and Fine
represent different levels of volume-control sensitivity; the
Reference setting gives absolute increments in 0.5dB steps.
Input Trims – Input trims are used to compensate for variations
in output levels of different source equipment. If, for example,
your CD player is louder at a given volume display value than
other inputs, you can attenuate it by using this setting so that it
matches your other components.
Use the source-select buttons to select the input you wish to
adjust, then the control knob to set (increase or decrease) the
input volume for that source.
Max. ‘On’ Volume – This can be used to limit the maximum volume
the ampli er operates at when it is rst switched on: the C31
comes on at the (reduced) “Max. On Volume” level if the last-
used volume exceeds this value.
If this item is set to ‘Disabled’, the C31 always comes on at the
last used volume, even if this is very loud.
Processor Mode – Processor mode enables you to x the gain
(volume setting) of your C31. The C31 (in combination with
a power amp.) can then be used to drive the front left and
right speakers of a surround-sound system, when fed from a
separate processor. The volume of the entire system can then be
controlled using the processor.
Feed the sound from the processor into the TAPE input, then set
the gain of the C31 to match the ampli ers that drive your other
loudspeakers.
Reset – this restores all ampli er settings to their factory defaults.
