Using the ampliﬁers, Recording onto tape

Using the ampliﬁers

Listen selector bq

Selects the input you wish to listen to. The selected input signal is also sent to the TAPE RECORD OUT 6sockets to allow the signal to be recorded, assuming you have a tape deck connected. It is also sent to the PRE-AMP OUT sockets 5.

TAPE br

Push this switch in to listen to playback from a cassette deck connected to the ampliﬁer’s TAPE PLAY IN sockets 7.

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 source selected by the LISTEN SELECTOR bq.

VOLUME bs

Adjusts the volume level of the loudspeakers, headphone and pre-ampliﬁer 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 ﬂat 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 ﬂat 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 sufﬁcient to correct small deﬁciencies 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 8Ω and 2kΩ ﬁtted with a 6.3mm stereo jack plug. If your headphones are ﬁtted 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.

A65/A75/P75

POWER cp

Switches the ampliﬁer on and off.

Power indicator cq

When the ampliﬁer 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 ampliﬁer output overload. Switch the ampliﬁer 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 ampliﬁer 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-ﬁ equipment (an input source), e.g. CD, to a tape deck connected to the ampliﬁer, ﬁrst 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 ampliﬁers 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 ampliﬁer, 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.
