INITIAL ADVICE
Please ensure that you have read the instructions and are
operating the equipment accordingly.
Check all cables to your speakers and other components for
any loose or incorrect connections.
Ensure that the rest of the components making up your
system are operating correctly. A fault can occur in another
component or connecting lead that might appear to be an
amplifier problem.
The information on the display will tell you what modes the
amplifier is set to.
It is possible to reset the AV50 to the factory set defaults by
the following method:
1. Press the RESTORE button on the handset.
2. Press the front panel MODE button within 3 seconds and
the CALIBRATION legend on the display will begin to
flash.
3. Press the front panel EXT DECODER button within 3
seconds.
All the segments on the display will flash to indicate a
complete reset.
If any problems still persist you may find the following
suggestions useful.
SYMPTOM: NO SOUND OR FAINT SOUND
THINGS TO
CHECK:
■ Are the speakers connected correctly?
■ Is the source you wish to listen to connected and operating correctly?
■ Is the correct input selected?
■ Is the unit switched on and the POWER LED green?
■ Is the volume turned up?
■ Is the mute switched off?
■ Is the tape monitor ® selected?
SYMPTOM; NO SOUND FROM ONE LOUDSPEAKER
THINGS TO
CHECK:
■ See points listed above.
■ Is the balance control set to centre position?
For the centre or rear channel: ensure these are not switched off via the remote. Also try adjusting the channel
volume.
ADVICE: To check a source component, swap the phono leads over (L with R) at the source equipment only. If the fault
changes over to the other channel, then the fault is in the source component or the cable.
SYMPTOM: SOUND NOT COMING OUT OF REAR SPEAKERS
THINGS TO
CHECK:
■ Is Dolby Pro Logic selected? The relevant legend on the display should illuminate.
■ Are the rear speakers connected properly?
■ Have rear speakers been switched on (via the remote)?
■ Are you replaying Dolby Surround encoded materials?
■ Has the rear volume been turned up?
■ Is your source operating in stereo mode?
ADVICE: Even on Dolby Surround encoded material, sound does not come out of the rear speakers all of the time; the
amount of rear level also varies from film to film.
SYMPTOM: SOUND COMING OUT OF REAR SPEAKERS WHEN MATERIAL IS NOT DOLBY SURROUND ENCODED
ADVICE: There is nothing to check here. Sometimes on normal broadcasts phase differences in the two channel recording
can confuse the surround steering circuitry, allowing certain signals to be heard from the rear speakers. You can of
course switch off the rear speakers.
SYMPTOM: UNABLE TO MONITOR VIDEO FROM THE ALPHA AV50 ON YOUR TV
THINGS TO
CHECK:
■ Is your TV switched to the correct AV input?
■ Have you connected the TV correctly to the video monitor socket on the amplifier?
• Have you selected the right video input via the source selector?
■ Is the amplifier properly switched on?
