channel signals. However, this indicator does
not light if the rear speakers are set to “NO”.

5 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 unit downmixes the
source sound (based on the speakers settings).
When using sound fields like “LARGE
HALL” or “SMALL HALL”, the unit adds
reverberation based on the source sound.

L (Front Left), R (Front Right), C (Center
(monaural)), SL (Rear Left), SR (Rear Right),
S (Rear (monaural or the rear components
obtained by Pro Logic processing))

Output channel: Rear speakers absent
Sound Field: A.F.D.

By adjusting the surround parameters and the
equalization of the front speakers, you can
customize the sound fields to suit your
particular listening situation.

Once you customize a sound field, the changes
are stored in the memory indefinitely (unless
the unit is unplugged for half a day).  You can
change a customized sound field any time by
making new adjustments to the parameters.

See the tables starting from page 74 for the
parameters available in each sound field.

Position your speakers and do the procedures
described in “Multi channel surround setup”
starting from page 14 before you customize a
sound field.

The SUR menu contains parameters that let
you customize various aspects of the current
sound field. The settings available in this menu
are stored individually for each sound field.

MULTI CHANNEL DECODING indicator
lights up when the tuner is decoding signals
recorded in a multi channel format.
When the selected sound field contains
adjustable surround parameters, the SUR
button lights up.
