OPERATION

Issue 3: March 2003

BEFORE  SWITCHING  ON

Plug the accessory IEC mains lead into the
rear panel socket, then the other end into a
wall outlet.

Turn the volume control on the front panel
to minimum (anticlockwise).

STARTING

. . . .

Press the 

POWER

button on the A308

amplifier - the 

blue

power LED on the front

panel will light indicating that the unit is
ready for use.  However, for about five sec-
onds no sound will be heard from your
speakers, and the red mute LED will light to
confirm initial mute action.

Unless using your amplifier for off-tape
monitoring (see paragraph opposite       )
ensure that the 

TAPE MONITOR

button

has not been pressed accidently, as other-
wise no sound will be heard through the
speakers.

Select the required audio input source by
pressing an appropriate function button on
the front panel or the remote control, and
adjust the volume control to obtain the pre-
ferred sound level.

TAPE  RECORDING

To record, simply select the required source
with the input selector button on the front
panel.  This source will now be routed to the
A308’s 

TAPE RECORD

output for record-

ing by the external tape deck.
You will also be able to hear the selected
source through the loudspeakers.

Note - adjustment of the volume control has
no effect on the recording level.

OFF - TAPE  MONITORING

In conjunction with a 3-head cassette deck,
off-tape monitoring allows the user to com-
pare the recorded sound with the original
whilst a recording is being made.  To do
this, first select the required source in the
normal way and start recording.
The 

MONITOR

button on the front panel

can now be used to switch between the
source signal and the recorded version
allowing direct comparison.

The red LED just above the 

MONITOR

button confirms that the tape monitor func-
tion is operating.

Note that the recorded signal is selected
when this LED is lit.  On some 3-head tape
decks there is an additional 'tape/source'
switch which must be in the 'tape' position
for the above to work.

If in doubt, please refer to your tape deck
operating manual.
