hi Biasrocks , thank you i'll try it
hi ChrioN , there less problem than the gssl i think, there is some resistors changement , the link is in this thread, if i find it i'l post it.
To add a little more from memory.
After adjusting QBias, I set up the limiter as specified in the instructions.
20:1, Attack & Release full CW, Input & Output around midway point.
When I was aligning the meter for 10db of reduction, I used a -10dBu tone in my DAW and brought that up to around read 0dBVU (1.22vac) on the limiter. I went into GR metering and played with the input level until I was just bumping into the start of gain reduction, where the meter just started to show GR and then backed it off slightly to show no GR. That way when I increased the tone in my DAW by 10db I was guaranteed to be getting 10db of GR through the limiter. Then it was a matter of bouncing between the ON/OFF Attack position and adjusting the tracking to get it to read 10db of GR on the meter.
Regarding mods.
I mapped out all of the differences between MNats REV A version and three versions of the Urei schematic (REV A, AB, B). I setup the GC Amplifier and QBias control to be exactly like the "REV B" version of the schematic, which I verified against the real version of the limiter. It came down to 3 resistor value changes and one additional resistor; plus two more changes if you REALLY want to be picky and be true to the original version.
I like the sound a lot and I'm not having any issues with All Buttons In mode, aside from it sounding pinched if you hit it too hard and don't have your ATT/REL settings in an appropriate spot.
I will say, that it seemed to be a bit more challenging setting up the REV A metering when compared to the REV J I completed a while back. But the resulting sound was well worth the trouble.
