adjusting listening settings

The A18 allows you to customise the balance, bass

and treble levels of the amplifier to fit your system.

Adjustments can be made either on the front panel or by

using the CR10 remote control. Click the corresponding

button to view the current setting, then use the control

knob on the front panel (or

VoL +

–

buttons on the

CR10) to adjust.

balance

channel (left or right) relative to the other. Altering

the balance (from L9 to R9, via the neutral value 0)

may help to restore the stereo image for an off-centre

listening position.

bass

This setting allows you to increase or decrease the level

of low frequency elements in the sound within the range

+7 to -7.

Processor mode

The A18, in combination with a power amplifier, can

be used to drive the front left and right speakers of a

surround-sound system, when fed from a multi-channel

processor. The volume of the entire system may then be

controlled using the processor.
While in Processor mode, you can feed the sound from

the processor into

AV In

and set the ‘Proc mode volume’

of the A18 to match the amplifiers that drive your

other loudspeakers. Set this ‘Proc mode volume’ using

the

VoL+

and

VoL–

buttons on the remote. The last set

value of ‘Proc mode volume’ is remembered whenever

Processor mode is selected.
Processor mode may be toggled on and off (when

is selected as the source) by using the front panel

processor Mode

button or

proc

on the remote. ‘PROC’

remains lit on the display while Processor mode is

active.
