These settings let you adjust the various parameters that control the audio
output to the Cinema BD system’s 5.1-channel speaker system.
Audio output: This option lets you set the following items:
HDMI Audio Out: In addition to digital video signals, the BD receiver’s HDMI
Monitor Out connection also carries digital audio signals.
• PCM: This option outputs a two-channel downmix (derived from the
program’s native audio format) via the HDMI output.
• Off: This option turns off the receiver’s HDMI audio output. We
recommend selecting this option so you can take full advantage of the
superior audio capability of your Cinema BD system.
Dynamic Range Control: This setting makes the loud and quiet parts of
music or a movie sound closer to the same volume – a process known as
compression. Compression lets you turn up the volume so you can hear
the quiet parts without the loud parts disturbing other people. NOTE: This
feature works only with Dolby Digital programs that have been specially
encoded. Three settings are available:
• Off: This setting never applies compression. Use this setting when the
volume may be as loud as you desire.
• On: This setting always applies compression. Use this setting when you
want the volume to be as quiet as possible without making it difficult to
hear spoken dialogue.
• Auto: This setting applies compression based on information encoded
within the Dolby Digital bitstream. The receiver will selectively apply
compression only during the most dynamic parts of the soundtrack.
Speaker Settings: This option lets you set the following items:
Test Tone: This setting outputs test noise through each of the loudspeaker
channels in the following order: Left (L), Center (C), Right (R), Right-
Surround (RS), Left-Surround (LS) and Subwoofer (SUB). Use the setting
to check that each loudspeaker is connected properly to the Cinema BD
receiver and to set the distances to the speakers.

IMPORTANT: If you have not yet set the speaker distances as described in
the Quick-Start Guide that was included in the box with your Cinema BD
system, you should use this screen to do so now.
To set the speaker distances:
1. First, measure the distance from the listening position to each of your
system’s speakers, except the subwoofer. Write down these distances.
2. Press the Enter button when the speaker you want to adjust is playing
the test noise and is highlighted on the menu screen. The Level and
Distance adjustment selections for that speaker will appear.

levels at this time.)
