API 525 500 Series Compressor Reviews

Single-channel Modular Compressor, 500 Series, Classic Reissue with Variable Threshold and Output Levels, "Ceiling" Control, VU Meter, and De-ess Function

With the API 525, you get to snag the sound of API's famous 525 — a modular compressor originally introduced in the 1970s. This compressor reissue is a "feedback" type of compressor, for classic sonic character and exceptional dynamics control behavior. Onboard the API 525, the cool multi-function "ceiling" control can lower threshold while raising output level to match, so you can adjust dynamics without changing level. As part of API's modular 500 Series, you'll enjoy classic-but-versatile character in a flexible and reasonably priced design, with the API 525.

API magic

By Bruce B. from Texas
Music Background: Singer/songwriter, music production

This will take a little getting use to. It is really simple to operate - Connect, twist knobs, be amazed.This thing sounds great on vocals and acoustic guitar. I have not use it on bass because I have a bass set up and have captured the sound I want with that setup.

It is truly a wicked little piece of gear. I am using it with the API 512V into the 525 then thru a UA 1176 for vocals.
512V and 525 are good for acoustic guitar.

Hey, it is API...Duh. You either like this stuff or you don't. Some people like Chevy and some people like Fords. It is a matter of taste. Me, I love the API gear.

How much do I love my 525's?

By Robert L. from New York, NY

Enough that I now have 4 of them. My favorite compressor. I got a second pair because I realized the one thing my recordings 'suffered from' when I work at other studios is I didn't have 525's to record through. I am one of those engineer's that records with compression by choice, and the 525 is outstanding for this. Never sounds bad, never squashes it too much, just makes what I'm doing sound better. I was thinking of getting a API 2500 instead, but the main thing I don't like about that particular model is the lack of a Ceiling knob. The Ceiling knob is a 'group' knob for the amount of gain and compression you want. If you want more or less of both, just turn the knob. I know that doesn't sound exciting, but in practice its the genius of this box. I have most of the classic compressors, yet the 525 sees the most action. Try it, you might like it too
