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, or by disconnecting the power lead. 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. LINE OUT 6 – Connect this output to the audio inputs of any unit with a line-level input, e.g., tape deck, etc. TAPE1/RECORD OUT 7 – Connect these output sockets to the input sockets of your cassette deck (usually labelled RECORD). TAPE1/PLAY IN 8 – 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. DVD 9 – Connect this input to the audio outputs of a DVD player. AV bk – Connect this input to the audio outputs of audiovisual equipment such as a VCR, laserdisc player, satellite or Nicam tuner. TUNER bl – Connect this input to the audio outputs of your radio tuner. CD bm – Connect this input to the audio outputs of your CD player or DAC (digital to analogue converter). AUX bn – Connect this input to the audio outputs of any unit with a line level output, e.g. tape deck, tuner, etc. PHONO bo – Connect this input to the output of your record player. This input provides RIAA equalization and is compatible with most high output moving magnet (MM) cartridges. 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 A80, as they will come on when the A80 is activated. This is useful if the power amplifier is remote from the A80, or otherwise difficult to access. If you are bi-amping with a power amplifier and wish to power both units on or off simultaneously, see page 10. REMOTE IN – This allows remote control signals to be received by the A80 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 A80 (into this input) using a suitable cable. Remote control signals acceptable to the A80 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 If you wish to use your A80 as a power amplifier, please consult your Arcam dealer. PRE OUT 5 – To use your 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 P80 power amplifier) you can bi-amplify (‘bi-amp’) suitable loudspeakers, giving significant improvements in sound quality (see page 12). The different output types The distinction between PRE OUT, LINE OUT and RECORD OUT output types is subtle but important. PRE OUT: This is the output that should be connected to your power amplifier. The output level varies with the volume control. LINE OUT: This output is taken before the volume control, i.e., the source being listened to is routed directly to this output. If you wish, this output may be connected to a recording device, such as a cassette recorder. Under no circumstances should this output be connected to a power amplifier. RECORD OUT: The output from the RECORD OUT connectors is dependent on the configuation of the amplifier. Full instructions for this output are given on page 7; briefly, if the amplifier is configured to ‘REC SOURCE’, then this output will carry the same signal as the LINE OUT connection. If the amplifier is configured so that you are recording a different source than the one you are listening to, then the RECORD OUT connections will carry the source being recorded.
