API Audio 2500 by Jim Keaney @ Devotion Recording
The API 2500 stereo compressor is my compressor of choice when it comes to my 2-buss mix. I mix mostly 'rock' genres, and this compressor glues my mixes together very nicely. I usually mix into this compressor with the gain reduction kissing around -2db. It's subtle but makes a big difference for me.
This device is laid out in a very straight-forward design which makes it easy to use and understand all the controls. It has the typical threshold, ratio, attack & release controls of many compressors, but it also offers some interesting others. It comes with API's patented "Thrust" circuit which I tend to leave on medium or normal, unless I'm looking to really crush something and get that pumping vibe happening (loud). It also has a knee control and API's "new" or "old" switch, which basically changes the compression from feeding-back or forward-feeding compression. Both offering unique results. The other controls include stereo linking, which lets the 2 channels (left & right) compress individually or work 'linked' together in increments of 60, 70, 80, 90, or 100%. Also has a hi-pass and low-pass option. Finally, the output section includes a bypass AND "in/out" button, in case you'd like to keep the "sound/color" that the unit adds to the signal, without actually using any compression. It definitely has a "color", which API is known for. In particular, I love the saturation/glue I can get from the "make-up gain" knob. There are lighted VU meters for each channel with a switch for viewing In, Out & Gain Reduction.
This comp is known to shine on the drum-buss. I like to use it for tracking vocals as well. Highly recommended and I can't foresee myself ever selling mine.
