The following modes will be available: Stereo, Dolby Digital, DoIby
Pro Logic, Dolby 3 Channel, DTS, Digital Stereo.
Note:
Some modes may be disabled dependant on the actual input signal.
Modes can be selected by use of the front panel MODE
button or the MODE buttons on the remote handset.
The modes that are selectable are dependant on the actual source
material being played.These are shown below:
PCM DIGITAL INPUT(CD SIGNAL): Digital stereo, Dolby
Pro Logic Digital, DoIby 3 Channel (if no rears are selected).
DOLBY 2 CHANNEL: Dolby Digital Stereo, Dolby Digital Pro
Logic, Dolby Digital 3 channel (if no rear speakers are selected)
DOLBY MULTI CHANNEL: Dolby Digital stereo mx (mix
down), Dolby Digital XXX eg 3/2/.1
DTS 2 CHANNEL: DTS Digital Stereo
DTS MULTI CHANNEL: DTS Digital Stereo Mx, DTS Digital
XXX
ANALOGUE: Stereo analogue, Dolby Pro Logic - analogue,
Dolby 3 Channel (if no rear speakers are selected).
Source material, particularly DVDs, will vary from disc to disc in
the number of surround channels encoded. Frequently, you may
find only stereo has been encoded, particularly on older movies.
Below are some of the more commonly available formats.
If you wish to listen to a source that is not a 2 channel stereo
source you MUST change the mode to a stereo mode in order to
hear all of the sound correctly on the headphones. For example if
you are listening to a DVD player in 5.1 channel mode you would
have to set the mode to Dolby Digital Stereo mixdown when
listening on headphones. If you don’t you will not be able to hear
any of the main dialogue signals on your headphones because this
is a centre channel signal.
Adequate ventilation MUST be provided for the DAVE amplifier,
and it is strongly recommended that it is not stacked with other
products, particularly additional power amplification.
The DAVE surround decoding circuitry requires a temperature
controlled environment in which to function correctly. If the
internal temperature of the unit reaches a certain point, a cooling
fan will begin operating to cool the circuitry.You may hear this as a
very quiet whirring sound coming from the amplifier.This is normal.
If the temperature continues to rise the amplifier may shut itself
down to allow it to cool. If this happens the unit will switch into
standby mode and ‘Fault Condition Protection’ will be shown on
the display. When the unit has cooled down sufficiently the unit will
automatically switch out of standby again.
In addition, fan cooling is also provided for the two main output
channels.This cooling is only activated above a certain
temperature, and when there is a signal present, so any fan noise
will be masked as far as possible, by the loudspeaker output.
It is only possible to record from an analogue source.You cannot
record from any digital source. If you wish to record from a CD
player connected to one of the digital inputs you will have to make
a connection from the analogue outputs of the CD player directly
to your recorder or to the analogue CD inputs of the Alpha 10.
In the latter case you can then record the CD signal by pressing
the front panel RECORD button followed by the CD input button.
To record from a laser disc player connected to the AV analogue
inputs of the amplifier first press the RECORD selector followed
by the AV button.This will route the audio signals of the Laser Disc
to the VCR Audio Record Out sockets and the video signal to the
composite or S Video VCR OUT socket (S Video, Composite
video). Note: you may not be able to record the video signal if it
contains Macrovision copy prohibit signals.
The amplifier will automatically switch to the best source signal
when an input is selected if DECODE mode has been set to
'AUTO'. For example if you have a CD player connected to the
digital input and also an analogue connection to the CD inputs the
unit will default to the digital signal when CD is selected.To force
the unit to the analogue input press and hold the CD button until
Analogue is shown on the OSD or front panel display.This will take
about 4-5 seconds. If you press the CD button again it will reselect
the CD digital input signal.
