However, you should be aware of the following installation and operation precautions: 10. Power-cord protection Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords and plugs, and the point where they exit from the appliance. 1. Take heed of warnings and instructions You should read all the safety and operating instructions before operating this appliance. [. . . ] Should you require a new mains lead, contact your Arcam dealer. Plugging in Push the plug (IEC line socket) of the power cable supplied with the unit into the socket ( ) in the back of the unit. Put the plug on the other end of the cable into your power supply socket and switch the socket on. Arcam A65 or A75 amplifier + R ­ + L ­ + Right speaker ­ + ­ Left speaker A65/A75/P75 4 Wiring your loudspeakers Connecting to other equipment All of the input sockets (except PHONO) have the same sensitivity and may be used with equipment other than that labelled, if you need to do so. The use of high quality interconnect cables to and from other hi-fi equipment is recommended to ensure the best sound quality (sonic performance). Ask your Arcam dealer's advice on cable selection. PHONO/LINE switch bn (A75 only) If you don't have a record deck and therefore don't want to use the PHONO input socket, press this button in (with the tip of a pencil or a ball point pen) to convert the PHONO input to a LINE input for equipment such as a CD player, tuner, VCR etc. Press and release the button to use as PHONO input again. AV PROCESSOR/TAPE switch br (A75 only) Ground terminal bo If you are using the amplifier with an external processor such as a Dolby Pro Logic or Dolby Digital decoder you should select the AV processor. Connect the left and right audio output sockets of your processor to the corresponding AV/DVD input . Press and hold the TAPE MONITOR switch for five or more seconds, the amplifier switches to a fixed gain. This allows the volume control of your processor to act as a master control and adjust the sound level of the speakers attached to both the A75 and the processor simultaneously. If you then switch back to another input, for example, CD, the volume control is switched back in circuit again and the amplifier functions as normal. This is normal. Connect the earth lead (if fitted) from your turntable or pick-up arm, to this. 8 br WARNING: If the AV PROCESSOR/TAPE switch is set to AV PROCESSOR and the LED is illuminated, do not use the AV/DVD socket for any equipment except a processor with its own volume control. Otherwise this could result in a signal being sent to your loudspeakers at high levels which may damage the loudspeakers. PRE-AMP OUT 5 You will only need to use these sockets if you have a separate power amplifier. To use your amplifier as a preamplifier connect these sockets to the input sockets (POWER AMP IN or PWR AMP IN) of your power amplifier. If your power amplifier is an Arcam P75, P85 or Alpha series you can use it in conjunction with the power amplifiers in your integrated amplifier to bi-amplify suitable loudspeakers. See the section `Bi-wiring and bi-amping loudspeakers' for details. TAPE RECORD OUT 6 Connect these output sockets to the input sockets of your cassette deck (usually labelled RECORD). TAPE PLAY IN 7 Connect these input sockets to the output sockets of your cassette deck (usually labelled PLAY). 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. 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! BASS ck 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 . If your cassette deck is a 3-head type it is possible to monitor the actual recording on the tape. Switching this button in/out enables you to do button an A/B comparison between the source signal and the recorded signal. Rotate clockwise to boost the bass response and anticlockwise to cut the bass response. For a flat response leave in the central `click' position. bq TREBLE cl Rotate clockwise to boost the treble response and anticlockwise to cut the treble response. The range of the tone controls has been deliberately limited to approximately plus or minus 6dB (decibels) at the frequency extremes. [. . . ] Switch the amplifier off and wait for 2­3 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 goes green on switching on, there is a problem with the speakers or speaker cables. Check the speakers and speaker cables for short circuits before reconnecting them. [. . . ]
