±1 AES/EBU frame
Settable in 512 fs (24.576 MHz) steps
*The timing can be varied with respect to the Video
Unit installed in the LT 443D mainframe.
The settings are common to the digital audio, silence
and word clock signals.
*Frequency, level, and audio click can be set to each
channel.
Other items (except timing) can be respectively set to
the 2-channel output.

Installing the LT 443D-DA Digital Audio Unit in the LT 443D
mainframe can output AES/EBU digital audio signals (four
systems), silence signals (one system), and 48 kHz word
clock signals.
The AES/EBU signal characteristics (e.g., output level, fre-
quency) can be independently set for each output system.
The sampling frequency is synchronized with the video sig-
nal of plug-in unit installed in the mainframe.

The LT 443D-CS Analog Composite Unit adds the
NTSC/PAL analog composite signal output capability to
the LT 443D mainframe. Various functions (e.g., ID
character, simple motion pictures, embedded audio,
NATURAL picture pattern *1) are provided.
*1: The NATURAL picture function is only usable when
the Option LT 443D-70 is installed in the mainframe.
