Enjoying Surround Sound
Source sound displays
The letters (L, C, R, etc.) indicate the source sound. The box around the letters varies to show how the amplifier downmixes
the source sound (based on the speakers settings). When using music sound modes such as HALL or JAZZ CLUB, the
amplifier adds reverberation based on the source sound.
The following table shows how the indicators light up when using AUTO FORMAT DECODING mode.
Although the table below shows almost all of the configurations available from multi channel surround signals, the ones
marked “
” are the most common.
* Signals with Dolby surround encoded flag OFF
**Signals with Dolby surround encoded flag ON
*** The sampling rate is displayed.
Notes
• The amplifier performs Pro Logic decoding and the display conforms to 2/0** when using the following movie sound modes with
2/0* or STEREO PCM format signals. (CINEMA A, B, C, V.M.DIMENS., and V.SEMI M.D.)
• When using music sound modes such as HALL or JAZZ CLUB with standard audio formats e.g., PCM, the amplifier creates rear
signals from the front L and R signals. In this case, sound is output from the rear speakers, but output channel indicators for the rear
speakers do not light.
