Understanding the multi channel surround displays (continued)
qh 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 “CINEMA ST.EX”, 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)), SBL (Surround Back Left), SBR (Surround Back Right)
Example:
Recording format (Front/Surround): 3/2
Output channel: Surround speakers absent
Sound Field: A.F.D. AUTO
L C R
SL SR
LFE
qj 
: 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 light 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.
qk SW: Lights up when sub woofer selection is set to “YES” (page 20) and the audio signal is output from the SUB WOOFER jacks.
Customizing sound fields
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. You can change a customized sound field any time by making new adjustments to the parameters.
See the tables on page 75 for the parameters available in each sound field.
To get the most from multi channel surround sound
Position your speakers and do the procedures described in “Multi channel surround setup” starting from page 19 before you customize a sound field.
Note on the displayed items
The setup items you can adjust in each menu vary depending on the sound field. Certain setup parameters may be dimmed in the display. This means that the selected parameter is either unavailable or fixed and unchangeable.
