Using your A80 amplifier

Front panel controls

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)
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
button on the remote control, or the
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
These buttons select the source connected to the
corresponding input.The input currently selected is indicated by
text on the display.
AV
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).

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 (
and secondary ( ) set of speakers attached to your amplifier.
SP2
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
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
and indicator lights on the left-hand side
SP1/SP2 PROCESSOR
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.
