Model 7400 HD/SD Sync Pulse Generator and Test Signal Generator
Setting the Audio Generation and Routing Parameters for Audio Generator A (Aud Gen
A Menu)
There are two generators on each 7400, Generator A and Generator B. Each of the two generators
on the 7400 are identical, with completely independent controls. The two AES digital audio outputs
are always synchronous with all of the video outputs – regardless of format – because all of the video
outputs can be locked to a common time base. Multiple tone generators can be used to identify multi-
channel content. Each generator supports sixteen audio channels and the content of each channel is
independently programmable. Choices include adjustable frequency tone generators, tone sweeps,
silence, timecode, audio clip playback from the 7400's secure digital card, and the external AES input.
All sixteen of these channels can be embedded in the SDI outputs. Each AES output can select from
any of the eight pairs that make up these sixteen channels.
This menu affects the Out 2A and Out 3A BNCs.
There are three types of audio output: Embedding, AES—goes to user-programmable output 2 (Out
2A) and 3 (Out 3A)—and Analog (output goes to 15-pin D connector).
The Aud Gen A menu shown below allows you to set the Channel Number, the Audio Source, to
make Embedded Audio selections, and to choose the channel for Analog Out.
Use the controls to set the following:
• Chan Number
