other channels, which include left & right surround, sides, center and center surround. These other channels
can have
EQ and be crossed over (creating a SUB channel), but the front left and right channels may not
have EQ , be crossed over (routed to the sub woofer(s)), or perform phantom center speaker. The Analog
Matrix mode processes an analog input signal only.
MONO : This mode routes the input signal to the center channel only, however, if the center channel is
crossed over, a sub channel will be produced. If the center channel is set to OFF or PHANTM in the
SETUP / INPUT / CONFIG sub menu, the input signal will be routed to the front left and right speakers.
CIRCLE SURROUND : The ENC (Encoded) and NON-EN (Non Encoded) Circle Surround modes are
intended for music playback, whereas the CINE mode is intended for Cinematic use. In all 3 Circle Surround
modes, the center channel operates dynamically in order to avoid collapsing any stereo imaging that may be
present toward the center channel. This works to maintain a wide left/right sound field in the front channels.
All Circle Surround modes provide multi-band left/right steering in the surround channels.
When the source music is Circle encoded, the intended mode is Circle ENC , leaving the NON-EN mode for
non Circle encoded music. CINE is a non-encoded mode that is intended to be used for mono, stereo or
matrixed film sources.
Circle Surround operates effectively with both encoded and non-encoded material, and allows the
processing of the front left/right and center channels as well as full bandwidth of the left and right surrounds.
Please refer to page 64 for additional Circle Surround setup options, selectable in the second page of the
SETUP / INPUT submenu.

After selecting a temporary mode for the current input channel, pressing the MODE button once more
returns the Casablanca III to the INPUT SELECT menu. While in the MODE menu, the MASTER VOLUME
can be controlled using the LEVEL UP / DOWN buttons.
Note : If the default MODE is DOLBY DIGITAL or DTS and a 96K signal is received, the Casablanca III will
momentarily display a message (if the MSG parameter is set to ON ) indicating that it is receiving a 96K
signal and [temporarily] changing the current mode to STEREO . It does this when the default MODE is 5.1,
because a 96K signal cannot be processed and output. Therefore the MODE is changed to STEREO in
order to have an output. The user can change this mode, after it has been changed to STEREO , by using
the front panel MODE button and selecting a different and applicable MODE . The user cannot change which
MODE the Casablanca III initially changes to when receiving a 96K signal when its default MODE for the
currently selected input is either DOLBY DIGITAL or DTS .
