Does anyone out there have any technical info for a DBX-118? These are circa 1980.
I have two of these, my friend has 3. I've been keeping them running for a few years now.
I managed to find a schematic for the motherboard. The plug-in modules, however, are a question mark.
There are three plug-ins. One is called the RMS board, the other two are VCA boards.
The RMS generates a DC control voltage by averaging the audio inputs.
The control voltage is applied to the VCA boards to control the output audio level.
My problem is no schematics for the plug-ins and no setup/alignment info for any of the adjustments. Although they seem to work, it would be nice to know how these things should be setup.
Yes, thanks Carl I do have that one.
The only mention I have found stating the VCA and RMS schematics are available is by email from a fellow and the email address is missing. Frustrating...
There are thumbnail images of both schematics but the resolution is way to low to get a clear image.
I have fixed a couple of these replacing chips but have no alignment procedure for the unit.
