down-mix into a stereo Left and Right output.
■ STEREO & STEREO DOWN-MIX MODE
If this button is selected and the supplied bitstream is
more than 2 channels, the decoder will automatically
implement a stereo down-mix. Otherwise, analog or
digital two channel signals are passed as conven-
tional stereo.
NOTE: Down-mix is a software based auto-
matic mixing function available within the
SP3. This process exists because whenever the
number of active decoder outputs or loud-
speakers selected in setup is less than the
number of channels in the Digital program,
some channel combining will be necessary to
present the program on the available number
of channels/loudspeakers.
As a part of any program's production, its pro-
ducers can set and adjust the type and ratios
allowed for down-mixing somewhat to ensure
optimum results without compromising the
full Multichannel balance. This is accomplished
by including specific data within the Dolby
Digital bitstream which represents different
mixing coefficients for the centre and surround
channel signals.
These will be detected by the SP3 and used to
produce the down-mix if this mode is selected.
D: VOLUME CONTROL / ROTARY ENCODER
Continuous rotary optical encoder for determining vol-
ume level as well as an input for most variable settings
and other selections within both the System and Source
menus.
Note that when the volume level is being adjusted the
display changes to large numerals showing the level in
decibels
E: HEADPHONE JACK
Stereo (3 conductor) 1/4" headphone jack. In 2 Channel
Bypass mode the Left and Right analog inputs appear,
amplified, at the headphone jack. When other sources
are selected a stereo down-mix is used.
