| Yeah, it is indeed a 4 channel dbx unit. I'm not sure how compatible
it is with other dbx units, i.e. it's 1970s vintage. It was intended
for use with quad open-reel machines in a home stereo.
Gotchas? The channels operate in pairs only, I believe. So if you
want to bounce three tracks down to one, you have to use the whole
thing to decode the three tracks, nothing left to encode the last
track...
Going price these days, in the $50-150 range.

I have one of these on my 1/4" 4-track strereo reel-to-reel deck.
It is dbx type II which is not compatible with tapes encoded with dbx
type I.
>>> Gotchas? The channels operate in pairs only, I believe.
Yes, this is true. Each pair can be switched to either be encoding the
incoming signal or decoding the oout-going signal. So, the reason I
use a 4-track dbx on my reel-to-rell is so I can monitor DECODED dbx
while it is being encoded on the inputs.
Before I used it for this purpose, I used it as a dbx unit for a
4-track multitracker. Since they work in pairs, if you want to record
track #4 while playing along with tracks 1-3, you have to listen to
track 3 in encoded form (i.e., highly compressed). Not ideal but you
might be able to get used to it. (I did.)
For what it's worth, dbx also made a 2-track version called the 122 (I
think) that has only 2 tracks worth of the same circuitry. It was for
use as a front-end to people who wanted dbx encoded stereo cassettes or
reel-to-reels. I've got one of these, also. In fact it's not even
plugged in right now so if anyone wanted to make an offer for it, they
could send me mail.
I'll try to answer any other questions if you can think of any.
