PC76-U Type - Where did this come from?
The Prochannel has compressors based on the PC76-U Type and PC4K-5 Type. Can you kindly tell me where these come from? I assume it's some vintage series of gear but what?

PC as in Pro Channel
76-U as in 1176 Universal Audio
4k-5 as in SSL 4000 series, possibly the 5 refers to its 5.1 surround capability.

That's all make believe of course.
BTW, the real 1176 was made and marketed by UREI.

The 1176 Compressor The Universal Audio or UREI 1176 is a FET (Field Effect Transistor) Compressor. It was developed in 1966 by Bill Putnam, and was originally rooted in the 1108 Preamplifier. It has become most renowned and common compressors along with the LA-2A in top of the line studios and recordings today. The 1176 is a Class A line level limiting amplifier. It does have a relatively high noise level for high end audio gear, and subsequent revisions have attempted to remove some of the noise, some of these are marked by the an LN following it (1176LN). Making Sense of the Controls Ratios The 1176 has ratios of 4,8,12,and 20 as well as an unconventional "nuke" option when all 4 are pushed in. It also has input and ouput gain adjustment, (the input essentially acting as your threshold, and the output as makeup gain.) The VU meter has options to show Gain reduction as well as show audio level or to switch the unit off.

You might also want to emphasize that "real" 1176's also have input and output level metering.

Real 1176s have a lot more meat in the low end and a presence in the upper vocal range that people find well matched to small speaker playback. I do find that the PC76-U is very close to operational aspects of a real 1176. It responds very similar to the real thing. The differences are the rich deep low end the outboard adds to a kick drum and the release response which is much less grainy and smooth on the real thing. The pump of the compressor is also more impactful when using outboard. But, that said, the Prochannel does a pretty darn good job overall. Roughly 70% of the real world experience. Regarding the SSL, I don't have access to one of those but I like the sound as it closely matches the response and tonality of a lot of Nashville records where the SSL 9000 rules as king. Quick and snappy. Also if you push it hard it takes on the sound of pop & rock records. Anyone have an SSL at their disposal for a direct comparison?

The 76 CW's software implementation of a rack mount Universal Audio 1176. I had a Purple version of this one:  The 4K is basically a bus compressor torn out of a SSL 4000 studio console. Again, CWs take on this compressor.

And Mike....if I recall correctly...you have a couple in you possession (dang you  ). And...you are correct...the full functionality is not there...I miss those buttons.

Actually no. They have input and output level controls but not input & ouput metering. The metering is either gain reduction or level ouput at +4 or +8.

Middleman, Yes, you are correct. Katie, I actually have a pair of Purple MC77s.... which I casually describe as 1176s. They have the extra metering options. best regards, mike
