1 OPT: Lights up when the source signal is a
digital signal being input through the
OPTICAL terminal.
2 COAX: Lights up when the source signal is a
digital signal being input through the
COAXIAL terminal.
3 MULTI CH IN 1/2: Lights up when MULTI
CH IN 1 or 2 is selected.
4 MPEG: Lights up when MPEG signals are
input.
Note
Only the front 2 channels are compatible with
MPEG format. Multi channel surround sound is
downmixed and output from the front 2 channels.
5 ; DIGITAL: Lights up when the receiver is
decoding signals recorded in the Dolby
Digital format.
6 PRO LOGIC: Lights up when the receiver
applies Pro Logic processing to 2 channel
signals in order to output the center and
surround channel signals. However, this
indicator does not light if the center and
surround speakers are set to “NO”, and
“A.F.D.” or “NORMAL SURROUND” is
selected.
Note
Pro Logic decoding does not function for MPEG
format signals.

7 L.F.E.: Lights up when the disc being played
back contains the LFE (Low Frequency
Effect) channel. When the sound of the LFE
channel signal is actually being reproduced,
the bars underneath the letters lights up to
indicate the level. Since the LFE signal is not
recorded in all parts of the input signal the bar
indication will fluctuate (and may turn off)
during playback.
8 SW: Lights up when sub woofer selection is
set to “YES” (page 19) and the audio signal is
output from the SUB WOOFER jacks.
9 Playback channel indicators: The letters
(L, C, R, etc.) indicate the channels being
played back. The boxes around the letters
vary to show how the receiver downmixes the
source sound (based on the speakers settings).
When using sound fields like “DIGITAL
CONCERT HALL”, the receiver adds
reverberation based on the source sound.
L (Front Left), R (Front Right), C (Center
(monaural)), SL (Surround Left), SR
(Surround Right), S (Surround (monaural or
the surround components obtained by Pro
Logic processing)), SB (Surround Back (the
surround back components obtained by 6.1
matrix decoding))
Example:
Recording format (Front /Rear): 3/2
Output channel: Rear speakers absent
