See Steve's second post of 3/16/02 above.. and connect the outputs (on the right) to whichever channels of the mag input you'd like to sound to come out of.

Simple and cheap.

SO problem is solved for controlling CP50 non sync....better is to use 10K LOG potmeter for controlling audio from CD/DVD to CP.

But why did dolby did such stupid non sync on it?? Is stupid when non-sync don't pass EQ and main volume controll. They might been for external (magnetic in that days) but even then is better to have central processor unit and all sources connected to it(CP50 in this case)and controlling volume along with EQ on it.

The CP50 was designed in the mid '70s to be a retrofitted to 4 or 6 track mag systems. The Ampex system for instance, had a number of inputs on a motorized Ledex switching system. The original unit did not even have an internal VCA fader card and used the house 4 or 6 track mechanical fader instead.

Later units had a Cat. 117 fader card controlled by an external fader box which was a 100K linear pot.

The CP50 succeeded beyond expectations and a lot of mono systems were starting to be upgraded to stereo and this was the first choice of most.

A number of mods were made to the unit over time to help with its shortcomings and the CP50 was eventually superceded by the CP55.

An OK processor.....change all the boards and you get a wonderful processor. It was, however, cheaper to just replace it. Louis

That's basically what I did to get on-screen when my projector 2 input failed inexplicably right before the show. However I would like to take advantage of the center and surround channels and still have a single fader.

Honestly, I'd consider a small stereo mixer for such an application. You'd get volume control over your non-sync material, and you could mix in a microphone for presentations and whatnot.
