Audio Generator A Menu
Setting the Audio Generation and Routing Parameters for Audio Generator A
There are two generators on each 7400 or 9400, Generator A and Generator B. Each of the two
generators 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 2 A and Out 3 A BNCs.
There are three types of audio output:
Embedded – audio embedded on the SDI output
AES – goes to user-programmable output 2 (Out 2 A) and 3 (Out 3 A)
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.
