Standby power
For remote standby operation, the amplifier's control power
supply is kept powered up all the time the unit is connected to
the mains supply. The front panel power switch powers down all
other circuitry. Power consumption in this mode is less than 2W.
This means that even though the power switch is off, it may be
possible to hear a slight residual hum coming from the mains
transformer inside the amplifier. This is perfectly normal. If the
unit is to be left unused for an extended period, we recommend
that it is disconnected from the mains supply by switching it off
at the wall socket.
Connecting to other equipment
The use of high quality interconnect cables to and from your
amplifier is recommended to ensure the best sound quality.

AUX
– Connect this input to the audio outputs of any unit
with a line level output, e.g. tape deck, tuner etc.
NOTE: The AUX inputs must not be used if the phono module
is fitted. When this is fitted AUX becomes an output carrying
the equalised phono signal at line level.

PHONO
– As standard, phono inputs are blanked. Phono
inputs are provided on a separate plug-in module which your
Arcam dealer or distributor can supply and fit. This module
is compatible with most high output moving coil and moving
magnet cartridges (MM) and low output moving coil cartridges
(MC). MM or MC is selected via the
Phono earth terminal – For connecting your turntable earth
lead (if fitted). Note that this terminal must not be used as a
safety earth.

TRIG OUT
REMOTE IN
(12V in and out) – These
AND
connections are intended for use in multi-room installations.
– This output provides a 12V signal whenever the
TRIG OUT
unit is switched on (i.e., not off or in standby). This signal
can be used to switch on automatically power amplifiers
(or other equipment) connected to the A90, as they will
come on when the A90 is activated. This is useful if the
power amplifier is remote from the A90, or otherwise
difficult to access.
– This allows remote control signals to be received
REMOTE IN
by the A90 if the remote sensor is covered (or otherwise
not 'visible' to the remote control). An external sensor
is used to receive the signals from the remote control,
which are then fed to the A90 (into this input) using a
suitable cable. Remote control signals acceptable to the
A90 must be in modulated RC5 format, with a voltage
level of between 5V and 15V.
Note that in normal use there is no need to make any
connections to these sockets. If you would like to make use of
these features, please contact your dealer for more advice on
how to make the connections and on what type of cable to use.
Pre/power amplifier connections

– To use your integrated amplifier as a power
PWR IN
amplifier, connect the output of your pre-amplifier to the
sockets.

Press in the
switch
PRE/PWR
select separate pre-amp/power amp mode. Under these
circumstances your A90 has exactly the same specification and
performance as a power amplifier (see page 10).
6
– To use your integrated amplifier as a pre-
PRE OUT
amplifier, connect the
sockets to the input sockets
PRE OUT
of your power amplifier. With a power amplifier of the correct
gain (e.g. the P90 power amplifier) you can bi-amplify ('bi-amp')
suitable loudspeakers, giving significant improvements in sound
quality (see page 12).
