manual abstract
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. Ensure the receiver is in a clear line of sight from the remote control to allow signals to be received. A70 E 6 Recording With the Arcam A70 it is possible to listen and to record from one source, or to listen to one source while recording another. The record signal is sent to the TAPE output sockets. These sockets are suitable for use with almost any type of recorder (cassette, CDR, MD, VCR, reel-to-reel, etc.). To record the currently selected source, press the SELECT button to enter the menu system. Rotate the Control knob clockwise until the display shows ‘REC OUTPUT’. Press SELECT.‘REC’ is displayed, followed by the current setting. Rotate the Control knob counter-clockwise until ‘REC SOURCE’ is displayed. After a few seconds, the display reverts to showing the volume level and you are ready to record. To listen to one source whilst recording another, press the SELECT button to enter the menu system. Rotate the Control knob clockwise until the display shows ‘REC OUTPUT’. Press SELECT.‘REC’ is displayed, followed by the current setting (for example, ‘REC TUNER’). Rotate the Control knob until the desired source is displayed. After a few seconds the display reverts to showing the volume level and you are ready to record. The unit now sends the selected source (‘Tuner’ in the example above) to the TAPE OUT sockets while you listen to the same or an alternative source. TAPE button operation 5 To play back the recording from a cassette deck attached to the TAPE input, press TAPE.‘TP–’ followed by a two-letter abbreviation of the record out source is shown on the display (e.g. ‘TP–CD’). Selecting this input overrides the other source selectors. If the current record out is set to ‘REC SOURCE’ then the previous selected source is shown on the display. Pressing different source buttons on the front panel only changes the record output. Tape mode can be exited by pressing TAPE again. It is also possible to monitor a recording while it is being made, provided your cassette deck is a 3-head type. To do this, press TAPE. Switching this button in/out allows an A/B comparison between the source signal and the recorded signal. English A70 E 7 Setting up your A70 amplifier The A70 allows you to adjust listening settings to suit your taste, and to customise various features of the amplifier to fit your system.

Adjusting listening settings The default display mode is VOLUME, where the Control knob is used to adjust sound level. Press SELECT to enter edit mode and cycle through the other settings: BALANCE, VOL RES, I/P trims, etc. When a setting is selected, press SELECT again and adjust it with the control knob. Press ENTER to fix the change you have made and return to idle (volume) mode.
