FX Format

Automatic
NOTE: When AUTOMATIC is se-
lected for an input, and DTS soft-
ware is being used, there may be
a brief burst of noise before play-
back begins. This is inherent in
the current generation of DTS soft-
ware and does not represent a
problem with your DC-1. To avoid
this, set up an input as DTS only,
and use it for playback of DTS
software.

The FX FORMAT parameter in the Input Configuration menu allows the
DC-1's format switching option to be individually adjusted for each input.
Many "multi-format" source components, such as laser disc players, are
capable of outputting different signals depending on the software being
used. The DC-1 automatically identifies the format of incoming audio
New
signals, and selects an appropriate effect. The four selections available for
FX FORMAT on each input are: AUTOMATIC, PCM ONLY, AC-3 ONLY
and DTS ONLY. Each of these selections is described below.
When AUTOMATIC is selected, the DC-1 automatically identifies the
format of the incoming signal and selects an appropriate effect. Effects can
be chosen for each individual input and for each format in the INPUT
CONFIG menu.
To illustrate how AUTOMATIC would operate with a laser disc player, note
the following example which assumes an "AC-3 ready" laser disc player
used in conjunction with the Lexicon LDD-1 AC-3/RF Demodulator. This
example assumes the V-DISC input has the factory preset configuration
shown below, and that the LDD-1 is connected to COAX 1 on the DC-1.
The DC-1 V-DISC input is selected. A movie encoded with a Dolby Sur-
round soundtrack is put in the laser disc player and starts to play. The LDD-
1 recognizes that the movie is not AC-3 encoded, and automatically routes
the laser disc player's PCM (2-channel digital) signal to the DC-1. The
DC-1 identifies the signal as PCM and automatically loads the LOGIC 7
effect (as specified in the INPUT CONFIG menu).
Now, assume the movie is replaced with one that is encoded with a Dolby
Digital (AC-3) soundtrack. When it begins to play, the LDD-1 recognizes the
signal as being AC-3 encoded and demodulates it for the DC-1. The DC-1
automatically loads the 5.1 Logic 7 effect.
