Switching On & Setup
ENGLISH
So once you've wired everything up, what’s next?
First check aii connections again to make sure there are no
ioose wires or piugs in wrong sockets, check your speakers
for any shorts between terminals and turn the volume control
down. Switch your
TV on and select the A/V input on the TV
which is connected to the composite video MONITOR
OUTPUT © of the Alpha AV50.
Ensure that the source you wish to listen to is playing. Once
satisfied, switch the Alpha AV50 power on via the front panel
POWER switch and select the correct input that you want to
listen to by pressing the appropriate SOURCE switch on the
Alpha AV50 or on the remote handset.
Increase the volume control of the Alpha AV50 and you
should hear sound from the selected source coming from
your loudspeakers. If this is not the case, try other inputs on
the Alpha AV50 and/or recheck your system connections.
The fault finding guide at the end of these instructions will
also help you.
Once your system is working it is important to balance it for
your components and room environment.

DELAY TIME: Use the + and - keys to adjust the DELAY
TIME - Surround information is delayed to the rear channels
for psychoacoustic reasons. The range is adjustable and
indicated on the display in 1 ms intervals. In Dolby Pro Logic
mode only the range is adjustable between 15 and 30
milliseconds (ms), and is commonly set at 20ms for most
installations. In HALL and SIMULATED modes the range is
adjustable from 1ms to 32ms. The optimum delay time does
depend on the listening position. Use the chart below to
determine the delay time for the size of your room and
seating position. For example, when the distance from the
front speakers to the listening position is 3 metres and the
distance from the rear speakers to the listening position is 1
metre, the optimum delay time will be 20 ms.
