Arcam ALPHA AV50 - Manual (Page 9)

Using your Amplifier
ENGLISH
CENTRE SPEAKER MODE REMOTE CONTROL COMMANDS
The CENT OFF button, ® , on the remote control is used,
in set up mode only, to set the centre speaker mode. It has
no effect in Stereo mode. This setting is common for Dolby
Pro Logic and Dolby 3 Stereo. Different settings can be made
for the HALL and SIMULATED modes.
The following legends illuminate on the LCD display to
indicate the selected centre speaker mode.
Normal - For a standard centre channel loudspeaker.
Phantom - For no centre loudspeaker. This mode may be of
benefit if your left and right loudspeakers are of very high
quality and you prefer a simple system without a centre
speaker.
NOTE: In Dolby 3 Stereo mode you do not get the phantom
option.
Wideband - For larger centre loudspeakers capable of
working down to low frequencies (50Hz or below).
TEST TONE MODE
Pressing the TEST/FUNC button on the remote control will
put the AV50 in TEST TONE mode. This is an ideal test for
making sure all your speakers are connected properly and
will produce a sequential burst of noise through your
speakers starting with left, centre, right and then rear. The
signal is directed to each speaker in turn every 2-3 seconds
You should adjust the centre and rear volumes via the
remote control until you are happy that all loudspeakers
sound equally loud at your listening position. The TEST
TONE legend on the LCD display will illuminate and the
current active speaker legend will flash. If the Centre or Rear
channel levels are adjusted the noise will immediately be
directed to the speaker whose level is being set. To exit the
TEST TONE mode press TEST/FUNC for a second time.
TEST TONE is not available in STEREO mode and if you
select STEREO mode you will exit TEST TONE mode.
EFFECTS - The HALL or SIMULATED effects can be added
and set for each individual input, except TAPE, if required.
The selected effect overrides any Dolby mode currently
selected. When the EFFECT is turned off the last selected
Dolby mode will be turned on again. The two available effects
can be selected by scrolling through them by pressing the
EFFECT button on the remote control handset.
EXITING SET UP MODE
To exit from the set up mode press Restore for a second
time. The RESTORE legend will stop flashing and then go off
after a few seconds.
The Alpha AV50 has now been set to your personal settings
which you will be able to recall at anytime by pressing
Restore on the remote control.
Further system tuning will be required if you have a
subwoofer. You will need to adjust its level control and tune
the crossover frequency to integrate smoothly with your main
loudspeakers. Try a variety of source materials to help you
make these adjustments until you are happy with the sound.
The subwoofer instructions may also provide advice on
system balancing. Do not be concerned if the level
adjustment on the sub-woofer needs to be set near maximum
to achieve the right balance.
Most functions on the remote control are straightforward and
obvious to use.
There are a number of functions described below that will
allow you to optimise the way you use your system. Letters
in the left hand column refer to the remote control drawing.
o
INPUT SELECTORS: These switch the amplifier to the
required input. The PHONO button has no effect on
the AV50.
POWER: Switches the amplifier on or off from
standby. In standby mode all inputs and outputs are
muted, except the MONITOR OUT, TAPE OUT and
VCR OUT, to enable you to make unattended VCR
recordings provided you have selected the appropriate
input before putting the unit in standby mode. We
recommend that you disconnect your amplifier from
the mains if it is to be left unattended over a long
period of time, e.g. a holiday.
TEST/FUNC: Switches the TEST TONE on/off in Set
up mode only. It has no function in normal use.
MODE keys : UP and DOWN buttons will cycle the
Alpha AV50 through the three primary operating
modes. The + and - buttons have no function during
normal operation and are used only in Set up Mode to
adjust the delay time.
DOLBY PRO LOGIC feeds sound information through
rear speakers and front speakers (L, R & C). Use this
mode for surround encoded sources. Video tapes and
discs with surround encoding can be identified by
looking for the Dolby Surround logo.
