1Input selector indicators
The input terminal selected by the INPUT selectors
on the front panel lights up.
2 DISCRETE
Lights up when this unit decodes signals recorded
in the MPEG or Dolby Digital (AC-3) format and
outputs the intended number of signals contained
in those signals. Does not light when the input
signal is 2-channel stereo or when the input signal
is mixed down because the surround function is off.
3 PRO LOGIC
Lights when this unit applies Pro Logic processing
to two channel signals in order to output the centre
and surround channel signals.
4 Output channel indicators
Light to indicate which channels are being output.
L: Front Left R: Front Right
C: Centre (monaural) SL: Rear Surround Left
SR: Rear Surround Right
S: Rear Surround (monaural or the rear components
obtained by Pro Logic processing)
See the following page for details regarding the
channel indication.
When MPEG/DOLBY DIGITAL is pressed, the
number of channels in the signal being input are
shown on the display (Example: DOLBY DIGITAL
[3/2]). See the following page for details.
Understanding the Display
5 L.F.E
The letters “L.F.E” light up when the disc being
played contains the LFE (Low Frequency Effect)
channel. When the sound of the LFE channel signal
is actually being reproduced, the frame around the
letters also lights up. Since the LFE signal is not
recorded in all part of the input signal, the frame
may turn on and off repeatedly during playback.
6 S.WOOFER
Lights when sub woofer selection is set to “YES”,
“UNLOCK” is not lit, and this unit detects that the
disc being played does not contain the LFE channel
signal. While this indicator is lit, this unit creates a
sub woofer signal based on the low frequency
components of the front channels.
7 D.RANGE
Lights when the [D.RANGE COMP] parameter in
the menu is not set to OFF and a signal recorded in
the MPEG or Dolby Digital (AC-3) format is input
to this unit. See page 16 for details regarding this
setting.
8 B.BOOST
Lights when the BASS BOOST button on the front
panel is pressed to enhance the low frequencies.
9 UNLOCK
Lights when this unit is not capable of reproducing
a digital signal. For example, this indicator may
light up if the connected component does not
output signal, the disc being played does not
contain the signal, or no playback components are
connected (etc.).
