This drawing depicts the Audio Signal Generation and routing for
a single SPG/TSG Generator. Each of the two generators on the 7400
and 9400 are identical, with completely independent controls.

Audio Generation and Routing
Audio Generators
The diagram shown below depicts the audio signal generation and routing for a single SPG/TSG
Generator. There are two generators on each 7400 or 9400, Generator A and Generator B. Each of the
two generators on the module are identical, with completely independent controls.
Support for Analog and Digital Audio
The 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.
Sixteen Independently Programmable Audio Channels Per Generator
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 or 9400’s secure digital card, and the external AES input. Left/Right
channel ID that synchronizes to the cyclops feature can also be selected.
Audio Embedded in the SDI Outputs
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. Similarly, the stereo analog output of each
generator can be driven from any of these audio signal pairs.
