[. . . ] HANDBOOK/MANUEL/HANDBUCH/HANDLEIDING A70 Arcam A70 amplifier Amplificateur Arcam A70 Arcam-Verstärker A70 Arcam-versterker A70 English Français Deutsch N ederlands Safety guidelines CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN ATTENTION RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR CAUTION: To reduce the risk of electric shock, do not remove cover (or back). 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. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. [. . . ] 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 may flash if a fault has occurred ­ the fault type is shown on the display. You should unplug the amplifier and leave it for a few minutes before reconnecting. If the fault cannot be cleared, unplug your amplifier and contact your Arcam dealer. Source selectors 9 These buttons select the source connected to the corresponding input. The input currently selected is indicated by text on the display. AV 4 876 This input is similar to the other line level inputs on the amplifier and may be used with a VCR or a second recording unit (e. g. cassette deck). Control knob, SELECT and ENTER The control knob has two functions: < < as a volume control, to adjust the output of loudspeakers and headphones connected to the amplifier, and of the pre-amp output (PRE OUT). when used in conjunction with the SELECT and ENTER buttons, to customise amplifier settings (see page 8). Volume control settings It is important to realise that the position of the Control knob is not an accurate indication of the power delivered to your loudspeakers. The amplifier often delivers its full power before the volume control reaches its maximum position, particularly when listening to heavily recorded compact discs. However the amplifier also has to be capable of giving full power output from much lower level sources, such as tuners and cassette decks. Using these sources, the volume control setting may be much higher before distortion (audible overload) sets in. To compensate for this, the input levels of each source may be individually adjusted to avoid accidental overload (see page 8). SP1 and SP2 2 These buttons allow you to select and deselect the main (SP1) and secondary (SP2) set of speakers attached to your amplifier. The light above each button glows if the corresponding speakers are currently selected. If both lights are out the amplifier will appear not to work, as all speakers are switched off! PHONES 1 This socket accepts headphones with an impedance rating between 8 and 2k, fitted with a 1/4-inch stereo jack plug. If you wish to listen on headphones only, use the SP1 and SP2 buttons (if necessary) to mute the speakers. The headphone socket is always active. Remote control receiver 3 The remote control's infrared receiver is positioned between the SP1/SP2 and PROCESSOR indicator lights on the left-hand side of the front panel window. [. . . ] Connect the integrated amplifier to the high frequency (HF) terminals and connect the power amplifier to the low frequency (LF) terminals. You will need: Speakers ­ with four input terminals each (as with biwiring): these will be marked HF (High Frequency) and LF (Low Frequency). Two amplifiers ­ one of these would be the A70 and the other an Arcam power amplifier (e. g. Loudspeaker cables ­ two pairs of cables per loudspeaker or a suitably terminated cable set (a loom, probably prepared by your dealer and capable of being used for biamping in one length). Interconnect cables ­ one pair of high quality interconnect cables. Bi-wiring your loudspeakers Bi-wiring improves the sound of your system because it divides the high and low frequency signal currents into separate speaker cables. [. . . ]
