Orban Optimod 8000A.....?
 

Hello................NG
Does anyone know anything about the Optimod 8000A...?
Anyone still use it ...?
Can it be used for recording...?
Ruff....value these days....?
Thanks..........Mike

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.

And so is the remakable Robert Orban, it would appear! I know this is
a personal question, Bob, but do you go in for a re-cap every ten
years?

Thanks for a lot of great designs over the years. Long may you run!

It's a multiband compressor combined with a multiplex stereo generator.

Anyone still use it ...?

Some stations still do. If you aren't hitting it hard, it's fine for a
station that isn't trying for extreme loudness. The 8100 gives a little
bit better modulation but not by all that much.

Can it be used for recording...?

Not really, because the output is a multiplex composite signal.

I dunno, call one of the used equipment brokers. Harris-Allied's guys
always have some in stock. They are pretty common.

No, but I arrange for regular oil changes :-)
