Connecting to other equipment, Standby power

PWR IN

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. Sockets marked L (and R) on your amplifier should only be connected to sockets marked L (and R) on other equipment. All the line inputs have the same sensitivity and may be used with equipment other than that labelled, if needed.

TAPE1/RECORD OUT 8 – Connect these output sockets to the input sockets of your cassette deck (usually labelled RECORD).

TAPE1/PLAY IN 9 – Connect these input sockets to the output sockets of your cassette deck (usually labelled PLAY). If you do not have a cassette deck you can use this input for other (line level) equipment, such as a CD player, tuner, VCR, etc., but not a turntable.

VCR/TAPE2 RECORD OUT bk – These output sockets can be connected to the input sockets of VCR/second recorder (usually labelled RECORD).

VCR/TAPE2 PLAY IN bl – Connect these input sockets to the output sockets of your VCR/second recorder (usually labelled PLAY). Alternatively, you can use this input for other (line level) equipment such as a CD player, tuner, etc., but not a turntable.

DVD bm – Connect this input to the audio outputs of a DVD player.

AV bn – Connect this input to audiovisual equipment such as a VCR, laserdisc player, satellite or Nicam tuner.

TUNER bo – Connect this input to the audio outputs of your radio tuner.

CD bp – Connect this input to the audio outputs of your CD player or DAC (digital to analogue converter).

AUX bq – 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 br – 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 MM/MC back panel switch.

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 AND REMOTE IN 3 (12V in and out) – These connections are intended for use in multi-room installations.

TRIG OUT – This output provides a 12V signal whenever the 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.

REMOTE IN – This allows remote control signals to be received 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

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

Press in the PRE/PWR switch 7 on the rear panel to 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).

PRE OUT 6 – To use your integrated amplifier as a pre- amplifier, connect the PRE OUT sockets to the input sockets 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).
