Push this switch in to listen to playback from a cassette deck

connected to the ampliﬁ er's

It also enables you to monitor the recording being made on a

3 head cassette deck.

Note: If the tape switch is in you will be unable to listen to a

VOLUME

Adjusts the volume level of the loudspeakers, headphone and

pre-ampliﬁ er out sockets

The volume control is motorised and can be controlled

remotely with the use of a suitable remote control handset,

such as the CR-389 supplied (see the section 'Using the

remote control' for details).

DIRECT

Push this switch in to bypass the bass, treble and balance

controls. This switches these controls out of the circuit

(minimising the signal path) and will generally give a small

improvement in sound quality.

BASS

Rotate clockwise to boost the bass response and anti-

clockwise to cut the bass response. For a ﬂ at response leave

in the central 'click' position.

TREBLE

Rotate clockwise to boost the treble response and anti-

clockwise to cut the treble response. For a ﬂ at response leave

in the central 'click' position.

The range of the tone controls has been deliberately limited

to approximately plus or minus 6dB (decibels) at the frequency

extremes. This is usually sufﬁ cient to correct small deﬁ ciencies

in recordings or speakers.

BALANCE

Rotate clockwise or anti-clockwise to move the position of the

stereo image. This may be necessary if it is not possible to

sit centrally between the speakers. In normal use leave in the

central 'click' position.

SP2

Push the button in to select the loudspeakers connected to

the SP2

release the switch again.

HEADPHONE socket

Accepts headphones rated between 8Ω and 2kΩ ﬁ tted with

a 6.3mm stereo jack plug. If your headphones are ﬁ tted with

a different plug, contact your dealer for a suitable adaptor.

Inserting a headphone jack plug automatically mutes (i.e. cuts

off) the loudspeakers, but does not mute the

After a few seconds it will glow green and a slight click may

internal protection circuit is working.

If the indicator glows orange during normal use it may be due

to an ampliﬁ er output overload. Switch the ampliﬁ er off and wait

for 2 to 3 minutes before switching on again.

If the indicator continues to glow orange, switch the unit

off, remove all the speaker cables and switch on again.

If the indicator then goes to green when switched on this

indicates a problem with the speakers or speaker cables.

Check the speakers and speaker cables for short circuits

before reconnecting them. If the indicator continues to glow

orange with no speakers connected, contact your Arcam dealer.

Note that the power indicator glows orange when the ampliﬁ er is

muted from the remote control.

Remote control receiver

Make sure nothing is standing in front of the remote control

receiver, otherwise messages from the remote control handset

cannot be received and it will appear not to work!

Recording onto tape

To record from another piece of hi-ﬁ equipment (an input

source), e.g. CD, to a tape deck connected to the ampliﬁ er,

ﬁ rst select the

tape deck into its record mode. Press

The CD signal will now be recorded onto your cassette deck.

If your cassette deck is a 3-head type it is possible to monitor

the actual recording on the tape. To do this push the

button

an A/B comparison between the source signal and the recorded

signal.

Using a remote control

The A65 and A75 offer remote control of the input selection,

volume control and mute via the CR-389 remote handset

supplied. It may also be possible to operate these functions

with other remote control handsets that use the Philips RC-5

protocol.

If the ampliﬁ ers are muted via remote control, the power

indicator glows orange. To cancel the mute function, press
