Front Panel Functions
ENGLISH
BASS - Rotate clockwise to boost the bass response
and anti-clockwise to cut the bass response. For a flat
response leave in the central 'click' position.
TREBLE - Rotate clockwise to boost the treble
response and anti-clockwise to cut the treble
response. For a flat response leave in the central
'click' position.
eH) HEADPHONES - This socket accepts headphones
rated between 8 ohms and 2k ohms fitted with a
6.3mm stereo jack plug. If your headphones are fitted
with a different plug contact your dealer for a suitable
adaptor. Plugging in a pair of headphones
automatically mutes all the loudspeaker outputs and
the MODE defaults to STEREO. It does not mute the
LEFT/RIGHT preamp out or SUB OUT sockets.
® VOLUME - Adjusts the volume level of all the
loudspeaker and preamp outputs simultaneously.
© BALANCE - Rotate clockwise or anti-ciockwise to
move the position of the stereo image. This may be
necessary if it is not possible to sit centrally between
the speakers. In normal use leave it in the central
'click' position. The BALANCE control will only affect
the left and right front speakers and headphones,
assuming that DIRECT is not switched in.
Note that bass, treble and balance controls will affect the
main left and right loudspeakers only.
® DIRECT - Pressing in bypasses the bass, treble and
balance controls in all modes.
POWER - Switches the Alpha AV50 fully on or off.
When this switch is on the AV50 may be put in to
standby mode with the remote control handset.
EXT DECODER SWITCH -This switch allows access
to the AVSO's internal power amplifiers via the volume
control. The PROCESSOR legend on the LCD display
will illuminate and all others will blank, except for the
centre, rear and left/right MUTE legends if active,
when the EXT DECODER switch is operated.
N.B. This switch cannot be operated by remote
control.
MODE SWITCH - Enables switching between Dolby
Pro Logic, Dolby 3 Stereo and Stereo. This button has
no function if headphones are plugged in.
SOURCE SWITCHES - Use to select the input you
wish to listen to or record from (see RECORDING
below also). The LED above the input switch will light
to indicate which input is currently selected. REMOTE RECEIVER - This is housed behind the
badge in the top left hand corner of the amplifier.
Ensure the remote receiver is not obscured or
commands from the remote control handset will not be
received.
RECORDING
The audio signal of the selected input is also sent to
the TAPE OUT and VCR OUT sockets. This enables
you to record from CD on to a video cassette recorder
or the audio of a laser disc on to a tape cassette
recorder. It is possible to record from VCR to TAPE
but not to record from TAPE on to the VCR.
TAPE - Allows you to hear the input as it is being
recorded on your audio tape deck. If it is a 3 head
cassette deck, switching its monitor button in/out will
allow you to compare the original signal with the
recording. The TAPE button overrides any other
selected input.
FRONT PANEL DISPLAYS
