ENGLISH
Volume display
To change the volume display from decibels (-95 to 0dB) to arbitrary
volume units (0 to 96 units) select VOL DB in the System Configure
menu. Press the input select button to turn off the volume in decibels.
Press the Mode button to exit.
Front IR
Used in conjunction with Custom Installation (C.I.) systems or IR
repeater systems, it may be desirable to disable the front panel IR by
setting FRONT IR to off (press the input select button to turn off). Press
the Mode button to exit.
Input gain trim
The relative levels of the inputs can be adjusted by gain trim. This
allows each to be adjusted so that each sounds the same in terms of
average loudness when you switch between them. Pick the loudest
sounding source and trim its level until it matches the average
perceived level of the others. Repeat this process if other sources also
stand out as louder than the average.
To set the input gain trim for each source, select INP TRIM in the
System Configure menu. Select the input required and use the volume
control to set the gain between 0 and -12 dB (the available range is
restricted if the volume is set very low). Press the Mode button to exit.
Fixed level inputs
Any input of the 840A V2 is able to be set for fixed gain. Whenever this
input is selected the gain will automatically go to this value and will not
be adjustable by the volume control. This feature allows the 840A V2 to
be effectively used as a stereo power amplifier (for that selected input
only). For example, as well as operating as a pure stereo amplifier, the
840A V2 can provide the amplification for the front left and right channels
of a surround sound setup with an AV receiver providing amplification for
the other channels and controlling the overall system volume.
When listening in stereo use the 840A V2 and connected stereo sources
as normal for best possible sound quality. For surround sound, select the
fixed level input you have chosen on the 840A V2 and now use the
AV receiver to control the volume, select connected surround sound
sources etc. You may wish to re-name the fixed level input as “A/V mode”
or similar on the 840A V2. Make connections as below, the left and right
preamp outputs of the AV receiver connect to the fixed gain input chosen
on the 840A V2. As the gain can be fixed to any value it is easy to match
the level of the 840A V2 to that of the other AV channels.
To set a fixed volume for a source, select FIXED INP in the System
Configure menu:
Select the input required and set the fixed gain using the volume
control (the OFF setting does not disable the input but leaves the input
gain subject to the volume control which is the default setting). When
a source has a fixed input, the balance is always set to neutral. Press
the Mode button to exit.
On/Off control menu
When going in/out of Standby mode the 840A V2 can automatically turn
on and off other connected Cambridge Audio Azur models that have
control bus sockets. For this feature to work the units must be connected
together (see diagram) by RCA/phono leads. The sockets are colour-
coded orange on the rear panels of compatible Azur models. Loop out
from the 840A V2 Control Bus Out to the Control Bus In on another Azur
model (e.g. 840C). Continue the chain to other Azur models if required.
Now while the 840A V2 is on press and hold the Standby/On button
until ON/OFF CTR appears on the display:
Select the connected Azur models by pressing the appropriate input
select button. For example, CA XXXC for an Azur CD player (540C V2,
640C V2), CA XXXD for an Azur DVD player, CA DAB T for an Azur DAB
tuner etc.
Press ON & OFF to scroll through the options of ON (turns all Azur units
on only), OFF (turns all Azur units into Standby only) or ON & OFF (turns
all Azur units on and into Standby mode).
Press OK to confirm and exit.
