connected to the ampli ers TAPE PLAY IN sockets
7
.
It also enables you to monitor the recording being made on a
3 head cassette deck.

source selected by the
LISTEN SELECTOR
bq
.
VOLUME
bs
Adjusts the volume level of the loudspeakers, headphone and
pre-ampli 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
bt
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
ck
Rotate clockwise to boost the bass response and anti-
clockwise to cut the bass response. For a at response leave
in the central click position.
TREBLE
cl
Rotate clockwise to boost the treble response and anti-
clockwise to cut the treble response. For a 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 suf cient to correct small de ciencies
in recordings or speakers.
BALANCE
cm
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
cn
Push the button in to select the loudspeakers connected to
the SP2
4
speaker terminals. To disconnect the speakers
release the switch again.
HEADPHONE socket
co
Accepts headphones rated between 8 and 2k tted with
a 6.3mm stereo jack plug. If your headphones are 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 PRE-AMP OUT
sockets
5
.
POWER
cp
Switches the ampli er on and off.
Power indicator
cq
When the ampli er is switched on, this will initially glow orange.
After a few seconds it will glow green and a slight click may
be heard (as the output muting relay disengages). When the
indicator glows orange, the speakers are disconnected and an
internal protection circuit is working.
If the indicator glows orange during normal use it may be due
to an ampli er output overload. Switch the ampli 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 ampli er is
muted from the remote control.
Remote control receiver
cr
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- equipment (an input
source), e.g. CD, to a tape deck connected to the ampli er,
rst select the CD input with the input selector
bq
. Set your
tape deck into its record mode. Press PLAY on your CD player.
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 TAPE
button
br
in. Switching this button in/out enables you to do
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 ampli ers are muted via remote control, the power
indicator glows orange. To cancel the mute function, press
MUTE again or either of the volume up/down buttons on the
remote control handset. If you mislay the handset after muting
the ampli er, turn it off with the POWER switch
cp
for 20
seconds, then switch it back on again to allow the internal mute
system to reset.
