In 2 channel mode (
2CHMDE
) the available settings are
AUTO-DETECT
,
PRO LOGIC
and
NO PRO LOGIC
.
The 2 Channel Mode is used to tell the Casablanca how to decode a Dolby Digital signal with only 2 discrete
encoded channels. If the incoming signal contains an identifying ‘flag’ (a bit within the data stream which tells
the Dolby Digital chip what kind of signal it is) and this parameter is set to:
1)
AUTO-DETECT
, the Casablanca will decode the signal in the mode which it was intended to be decoded.
2)
PRO LOGIC
, the Casablanca will decode the signal in Dolby Digital and then Dolby Pro Logic.
3)
NO PRO LOGIC
, the Casablanca will decode the signal in Dolby Digital.
The possible
COMPRESSION
settings are
ON
or
OFF
. When this value is set to
ON
, the Casablanca will
apply the compression values set in
HI COMPRESSION
and
LO COMPRESSION
to an incoming Dolby
Digital signal.
The user has a choice of setting the
HI
and
LO
COMPRESSION
ratios individually. The valid range for both
is
OFF
to
7
.
Some source material may contain high levels of
LFE
which can over power a sub woofer or other speaker(s)
connected to the
SUB
output(s). Setting the
LFE
(button #
5
) value to
-10
will lower the
LFE
output by 10dB.
Please refer to page 23 for additional Dolby Digital set up details
