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
Lights up when MULTI CH IN 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.

DIGITAL
This indicator 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 two 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”, or the SPEAKERS button is set to
OFF and the A.F.D. or NORMAL SURROUND sound fields
are selected.
Note
Pro Logic decoding does not function for MPEG
format signals.

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

Play back channel indicators
The letters light up to 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 setting). When using sound
fields like “DIGITAL CONCERT HALL”, the receiver
adds reverberation based on the source sound.
