AES TONE GENERATOR
812-OP/M
MADE IN THE USA
A PRODUCT OF THE GENFLEX SYSTEM
For Future Generations
The GenFlex 812-OP/M is a high performance 24
bit digital audio generator. The 812-OP/M is a
single module for use with the SPG-812 GenFlex
frame. The function of thismodule is to produce a
single AES/EBU digital audio signal for use as a
digital tonesource or as a digital audio timing
reference.
The generator has a set of features designed to
make it fit into a wide variety of applications. These
features include genlocking of the audio to digital
or analog video within the Genflex frame. Also, the
user may select to have this module free run with
its high stability oscillator. Internally, the creation of
the audio tone is done with a 24 bit audio "wave
table" stored in ROM. The output from the ROM is
formatted and output as digital audio. The user
may select the amplitude and frequency of the
audio tone from a fixed set of 8 combinations.
Within this set of eight there are three frequencies
(1KHz, 400Hz, 60Hz) and three levels (OdBFS, 10dBFS, -20dBFS)* The module has the ability to
produce "digital silence" or one of the eight
combinational tones on the output.
There are three digital outputs conforming with the
AES3-ID interconnection
standard. This generator runs at the professional
sample rate frequency of 48kHz. LEDs are used to
indicate tone frequency and level, digital silence,
lock status, and power indication. Further, the user
has control of some of the user status bits through
dip switches on the module.
The GenFlex audio generator is built with quality
throughout the unit. With its ability to produce 24
bit digital audio, it can produce the highest
resolution audio available in the AES3 format. The
812-OP/M is an addition to Link's GenFlex family
of analog/digital generator products. It is designed
to reside in
auxiliary slots with a possible total of five modules
plus one 812-OP/E audio module.
* 60Hz tone has 2 levels (OdBFS and -20dBFS).
The other tones have three levels.
* 60Hz tone has 2 levels (0dBFS and -20dBFS).
The other tones have three levels.
