API 527 Compressor #1291-13 (Used)

API 527 Discrete 500 Series Compressor with Thrust Circuit

The API 527 compressor is a single channel module based on API's 225L discrete channel compressor. The 527 features comprehensive controls including variable attack, release, ratio, and output gain controls. The unit also includes API's patented 'Thrust' circuit, first offered on the 2500 Stereo Bus Compressor. A 10 segment LED meter is switchable between gain reduction and output level.

"Anyone who has used the 225L compressor found in API consoles has expressed a longing for the same kind of flexibility and control in the 500 Series for some time" said Larry Droppa, President of API. "We're delighted to now offer the 527 to complement our vintage 525 compressor, which has been many engineers' favorite compressor over the years.
