Selectable

±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.
