We love the new addition to Gunpoint’s 51x Rack. qmp audio Built this lovely API 525 compressor. This pair of optionally linked compressors have a real sweet tone. We’re totally looking forward to be running these out on some vocals and bass tracks.
This 525 has an LED gain reduction meter. Two EA 2623-1 transformers feed the output and sidechain. This circuit uses 3 2520 opamps ( that’s quite a bit of soldering those tiny bits ). qmp audio chose to replace the originals 2510 opamp for a Lundahl LL1540 input transformer. Why not? A little extra iron can be a good thing. Another modification from the original 525 is the addition of a variable attack time.
