Lexicon DC-2 owner manual Automatic, AC-3 FX

DC-2 Digital Controller

System Configuration

The DC-2 can also be set up to automatically switch to an appropriate effect whenever PCM, AC-3 or DTS encoded material is detected at the input. This allows one input to be used for different formats. For example, in the factory default state, the V-DISC input will automatically load the appropriate version of Logic 7 when an AC-3, DTS, or PCM signal is present. The default selections for input effect assignment are shown below. More information is provided in the following FX Format section.

Input	PCM Effect	AC-3 Effect	DTS Effect
VCR	LOGIC 7	5.1 LOGIC 7	DTS LOGIC 7
DVD	LOGIC 7	5.1 LOGIC 7	DTS LOGIC 7
V-DISC	LOGIC 7	5.1 LOGIC 7	DTS LOGIC 7
TV	TV MATRIX	5.1 LOGIC 7	DTS LOGIC 7
AUX	LOGIC 7	5.1 LOGIC 7	DTS LOGIC 7
CD	MUSIC LOGIC	5.1 MUSIC	DTS MUSIC
TUNER	MUSIC LOGIC	5.1 MUSIC	DTS MUSIC
TAPE	MUSIC LOGIC	5.1 MUSIC	DTS MUSIC

The FX FORMAT parameter in the Input Configuration menu allows the FX Format DC-2'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-2 automatically identifies the format of incoming audio 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-2 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 2 on the DC-2.

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 DTS software and does not repre- sent a problem with your DC-2. To avoid this, set up an input as DTS only, and use it exclusively for playback of DTS software.
