About the indications in the display
(continued)
qf 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).
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))
Example:
Recording format (Front/Surround): 3/2
Output channel: Surround speakers absent
Sound Field: AUTO DECODING.
qg 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.
