Volume display
Mode
To change the volume display from decibels (-84 to 0dB) to arbitrary
volume units (0 to 72 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.
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.
Mode
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 740A 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 740A 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 740A
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 740A and connected stereo sources as
normal for best possible sound quality. For surround sound, select the
fixed level input you have chosen on the 740A 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 740A. Make connections as below, the left and
right preamp outputs of the AV receiver connect to the fixed gain input
chosen on the 740A. As the gain can be fixed to any value it is easy to
match the level of the 740A to that of the other AV channels.

To set a fixed volume for a source, select FIXED INP in the System
Configure menu:
Mode
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 740A 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 740A Control Bus Out to the Control Bus In on another Azur
model (e.g. 740C). Continue the chain to other Azur models if required.
