Understanding the Multi-Channel Surround Displays
Source sound displays
The letters (L, C, R, etc.) indicate the source sound. The box around the letters varies to show how the receiver downmixes
the source sound (based on the speakers settings). When using music sound modes such as HALL or JAZZ CLUB, the
receiver adds reverberation based on the source sound.

• The receiver 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. (C. STUDIO A, B, C, V. MULTI, and V. SEMI-M.)
• When using music sound modes such as HALL or JAZZ CLUB with standard audio formats e.g., PCM, the receiver creates rear
