Configuration
The MC-1 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.
FX Format
The FX FORMAT parameter in the Input Configuration menu allows the
MC-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 MC-1 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.
Automatic
When AUTOMATIC is selected, the MC-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 2 on the MC-1.
NOTE: When AUTOMATIC is selected for an input, and DTS
software is being used, there may be a brief burst of noise before
playback begins. This is inherent in DTS software and does not
represent a problem with your MC-1. To avoid this, set up an input
as DTS only, and use it exclusively for playback of DTS software.
