C. MODE (Selects the operating configuration)
MONO: All left and right channel signals are combined for Mono operation and fed to the
LEFT FRONT, RIGHT FRONT, Balanced, Unbalanced and the corresponding 6 CHANNEL con-
nector outputs. The combined Mono signals of 80Hz and lower are also fed to the SUB-
WOOFER Output.
The Unbalanced CENTER Output can be activated in MONO by setting the rear panel
CENTER FILL Switch (25), to the ON position. This allows a Center channel loudspeaker to
be used during MONO operation.
STEREO: Left channel signals are fed to the LEFT FRONT Unbalanced and the LEFT Balanc-
ed Outputs. Right channel signals are fed to the RIGHT FRONT Unbalanced and the RIGHT
Balanced Outputs. The Left and Right signals at 80Hz and lower are combined and fed to
the SUBWOOFer Output.
The Unbalanced CENTER Output, which contains the combined left and right channel
signals can be activated by setting the rear panel CENTER FILL Switch (25), to the ON posi-
tion. This allows a Center channel loudspeaker to be used during STEREO operation.
HALL: ENHANCES TWO CHANNEL AUDIO SIGNALS. Left channel signals are fed to the
LEFT FRONT Unbalanced and LEFT Balanced Outputs. Right channel signals are fed to the
RIGHT FRONT Unbalanced and RIGHT Balanced Outputs. The Left and Right signals of 80Hz
and lower are combined and fed to the SUBWOOFer Output. The combined Left and Right
audio signals are also fed to a Digital Processor, time delayed, and then fed to the LEFT SUR-
round and RIGHT SURround Outputs. The time delay can be adjusted by the front panel DELAY
(ms) Switch.
The Unbalanced CENTER Output can be activated in HALL mode by setting the rear panel
CENTER FILL Switch (25), to the ON position. This allows a Center channel loudspeaker to
be used in the HALL operating mode.
CINEMA 1, TO REPRODUCE DOLBY SURROUND, PRO LOGIC DECODED MOVIE
SOUNDTRACKS:
Audio signals from a Dolby Surround encoded movie soundtrack are fed to the C39 Dolby
Pro Logic processing and decoding circuits which produce the following outputs.
Left audio signals are fed to the LEFT FRONT Unbalanced and LEFT Balanced Outputs.
Right audio signals are fed to the RIGHT FRONT Unbalanced and RIGHT Balanced Outputs.
The Dolby Pro Logic processing circuits also decode the center channel signals which in-
clude dialog, and feed them to the Unbalanced CENTER Output. The Dolby Pro Logic pro-
cessed monaural surround sound signals are fed to the LEFT Surround and RIGHT Surround
outputs.
The Left, Right and Center signals of 80Hz and lower are combined by the C39 and fed
to the SUBWOOFer Output.
The Dolby Pro Logic Indicator on the C39 front panel lights when the MODE Switch is in
CINEMA 1 position.
Dolby Surround encoding is also used for MTS and satellite broadcasts as well as
other audio-only program sources such as compact discs. Use the C39 CINEMA 1 mode
with its Dolby Pro Logic processing to enjoy listening to these other program sources.
