I came across this project
http://www.diyfactory.com/projects/diy12au7comp/diy12au7comp.htm
I am in no way a tech, have never used an oscilloscope and barely know ohms law. I have built quite a few Paia kits successfully and this doesn't look all that difficult. And I managed to figure out and fix a power supply problem in an Otari 5050. Any thoughts?
BTW, it is designed for -10db not +4, looks like it can have a balanced input, but not a balanced output, thinking a Jensen xformer may be the ticket there.
I have been using an ART MDC2001 for mixdown. But I'd like to get a dedicated compressor limiter for that function, something w/o too many knobs. (Giving a lot of thought to the ART Leveler or dbx 262.)
But this unit claims a gain of 10:1
"The overall gain, when not compressing, is fixed at about 10:1 (20dB). The idea of a "unity gain" limiter is only valid when you hope to never use the limiter, and have plenty of headroom for the peaks you hope won't happen. When you plan to compress a lot of peaks, and don't have gobs of headroom like the old tube studio systems, a compressor/limiter needs to have gain. I assume that you have a level control on the device driving the compressor (usually your mastering mixer) where you can adjust "drive" and thus the amount of compression."
I'm not clear on what the designer is saying here.
Plus I would have thought that 20dB of gain from -10 puts that in the +4 range? (isn't that a 12dB gain?)
I'd like the option to use this with my DAT which is +4. (The OTari is selectable.)
