These sockets will still accept bare wire or pin terminations. The “Camcon” connector will accept spade terminals, bare wires up to 4mm in diameter or a “Camcon” plug. “Camcon” plugs are available from your arcam dealer. ! ■ Connect your loudspeakers so that the red (positive; terminal on each loudspeaker is connected to the appropriate red terminal on the amplifier. Your loudspeaker cables may be clearly terminated to show polarity; if not, then the positive conductor can usually be identified by a ridge or coloured marking. Ensure that no stray strands are allowed to touch another cable or the amplifier's casing. This can cause a short circuit and damage your amplifier! ©,0 SP1 - DIRECT CONNECTION - Connect terminals © to your right speaker and terminals © to your left speaker ensuring correct polarity. ©,© SP2 - SWITCHED CONNECTION - To drive a second pair of speakers, connect terminals © to the right speaker and terminals © to the left speaker, ensuring correct polarity. Push the SP2 button in to listen to this second set of speakers. To listen on headphones and mute the loudspeakers use the SP2 connection and release the SP2 button. ENGLISH ■ Both pairs of speakers may be driven simultaneously provided each pair is rated between 8 and 16 ohms. To avoid overheating the combined load impedance as seen by the amplifier should not fall below 4 ohms per channel. CAUTION: Your Alpha 7/8 amplifier generates heat when in use, particularly at higher volumes. It is therefore most important never to obstruct the ventilation slots on the unit as this could cause overheating. NOTE ON VOLUME CONTROL SETTINGS It is important to point out that, when playing a heavily recorded CD, it is possible to drive the Alpha 7/8 amplifier at full power despite the fact that the volume control is only at 10 or 11 o'clock. This is because of the high output level from modern CD players. However the Alpha 7/8 amplifier also has to be capable of jiving full power output from much lower level sources, such as tuners and cassette decks. Using these sources, the volume control setting will be much higher before audible overload sets in. CONNECTING YOUR SOURCECOMPONENTS ■ Using a suitable pair of interconnect cables to connect each component, insert the red phono plugs into the sockets labelled 'R' and the other phono plugs into the sockets labelled 'L'. All of the line inputs (except PHONO) have the same sensitivity and may be used with equipment other than that labelled, if you need to do so. 0 TAPE RECORD OUT - Connect to your tape deck's input (RECORD). © TAPE PLAY IN - Connect to your tape deck's output (PLAY). © VIDEO - Suitable for connecting the audio outputs of an Audio/Visual product such as a VCR, Laserdisc player or Nicam tuner. © TUNER - For connecting your radio tuner. © CD - For connecting your CD player or DAC. © AUX - For connecting any unit with a line level output, eg. tape deck, tuner etc. © PHONO - For connecting a turntable fitted with a moving magnet (MM) or high output moving coil (MC) cartridge. For low output MC cartridges, ask your dealer for a suitable MC pre-amplifier. © PHONO / LINE SWITCH (Alpha 8 only) - Converts the PHONO input to an extra LINE level input. Press the button in to use as a LINE input. Press and release the button (it should then be flush with the rear panel) to use as PHONO input. © GROUND TERMINAL - For connecting your turntable's earth lead (if fitted). © PREAMP OUT - To use your Alpha 7 or 8 as a preamplifier connect the PREAMP OUT sockets to the input sockets (‘power amp in’) of your power amplifier. If your power amplifier is an Arcam Alpha 8P or 9P, or an Arcam Delta 290P, this may also be used in conjunction with the power amplifiers in your Alpha 7 or Alpha 8 to bi-amplify suitable loudspeakers. OPERATION © REMOTE RECEIVER (Alpha 8 only) - This is housed behind the badge in the top left hand corner of the amplifier. Ensure the remote receiver is not obscured or commands from the remote control handset will not be received. © LISTEN SELECTOR - Selects the input you wish to listen to. The selected input signal is also sent to the TAPE OUT sockets to allow the signal to be recorded, assuming you have a tape deck connected. © TAPE - For monitoring a recording on a three head cassette deck, set LISTEN to the desired input and press TAPE. Switching between 'TAPE' and 'SOURCE' on the cassette deck allows you to compare the original source with the recording. To listen to a pre-recorded tape, press TAPE. This will override the LISTEN selector. © VOLUME - Adjusts the volume level of the loudspeakers and headphones. ■ On the Alpha 8 only the volume control is motorised and can be controlled remotely with the use of a suitable remote control handset, such as those supplied with Arcam CD players or the Alpha 8 FM/AM tuner (see section on OPERATION BY REMOTE CONTROL for more details). © DIRECT - Bypasses bass, treble and balance controls when the switch is depres...
