This section describes how to operate your amplifier.

If your amplifier has not been installed for you, you should first read the section ‘Installation: A80’ 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. 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

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 876

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 8Ω and 2kΩ, 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.
