[sdiy] OT: Dynair Mini-Pre ???

[Glen]

Is anyone familiar with these units? 

The back panel has two inputs, one is labeled "lo" and uses a male XLR
jack. The other is labeled "hi" and uses a female RCA phono jack. The
output appears to be a balanced output, and makes use of a barrier-style
terminal strip. That's right, you connect the output cable to screw
terminals, instead of a jack.

The front panel has a toggle switch labeled "power", a neon power indicator
lamp, a small analog meter, and a rotary-style "level" control.

I'm not sure if these are old mic preamps, or if they are meant for some
sort of scientific instrumentation application. I tried searching the
internet, but didn't come up with very much. The Dynair company seems to
have either been bought by another company, or perhaps has simply ceased
operations.

I'd appreciate hearing from anyone that knows anything about these units.


thanks,
Glen
