Refer servicing to qualified service personnel. WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated `dangerous voltage' within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. [. . . ] 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 deck, etc. 6 ­ Connect this output to the audio inputs of any unit with a line-level input, e. g. , tape TAPE/RECORD OUT 7 ­ Connect these output sockets to the input sockets of your cassette deck (usually labelled RECORD). TAPE/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. bl ­ Connect this input to the audio outputs of your radio tuner. AV bk ­ Connect this input to the audio outputs of audiovisual equipment such as a VCR, laserdisc player, satellite or Nicam tuner. 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. 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. A70 E-5 E nglish Using your A70 amplifier Front panel controls This section describes how to operate your amplifier. If you are installing the amplifier yourself, you should first read the `Installation' section on page 4. POWER (and power indicator light) bk Switches the unit on and off. (You can also switch the amplifier into standby mode with the remote control handset. ) The light indicates the status of the amplifier. A red light means the amplifier is in standby mode (press the POWER/STANDBY button on the remote control, or the POWER button on the front panel, to switch between standby and powered-up modes). When you switch your amplifier on, the light glows amber for a few seconds, during which time the speakers are disconnected. The light changes to green when the amplifier is ready for use. The light may flash if a fault has occurred ­ the fault type is shown on the display. [. . . ] This avoids signal distortions arising from the high and low frequency currents interacting with one another within a single cable, as in conventionally wired systems. You will need: Speakers ­ with four input terminals each: these will be marked HF (High Frequency) and LF (Low Frequency). Loudspeaker cables ­ two pairs of cables per loudspeaker (which may be joined at the amplifier end if your amplifier has only one pair of output terminals per channel), or a suitably terminated cable set (a loom, probably prepared by your dealer and capable of being used for bi-amping in one length). How to set up a bi-amped system 1. Remove the terminal links on the rear of your loudspeakers. WARNING: This step is essential or damage to your amplifier may result which is not covered under warranty. [. . . ]
