Does anyone know anything about the Optimod 8000A...?


Used to use one.

Anyone still use it ...?


Probably - the smaller stations probably still have one, and the newer ones

may have
it as a backup if they still maintain an analog program STL feed.

Can it be used for recording...?


Why would you want to?

Ruff....value these days....?


Tell you what...if you have one, and $200 to go with it, I'll take it off

your hands.

Thanks..........Mike


Sure. Sorry to abuse your curiosity, but these boxes are some 10-20 years

old, and
they're really designed as the final link in a broadcast audio chain. Good

in their
day, today's technology (DSP, mostly) has far outstripped the

previously-novel way
that this machine dealt with clipping and compression artifacts.


They were made between 1975 and 1980, so they are actually between 24 and 29
years old.

There was a recording studio version made called the 418A that used the 8000's
audio processing but with user-selectable pre-emphasis and no low-pass filters
or clippers. It can be useful as a vocal limiter.

In general, these units will require replacement of the electrolytic
capacitors in the power supply, particularly the ones located close to the
power regulator transistor heat sinks. If this is done periodically, they seem
to be more or less immortal.
