Alta Moda AM-10 500-Series Compressor/Limiter - Used  From Alta Moda

The Alta Moda Audio AM-10is a single channel compressor/limiter designed for use in API? 500 Series compatible rack systems. The AM-10 features a discrete FET gain control element with independent compression and limiter functions.
The compression section of the AM-10 uses a soft-knee feedback-type topology, reminiscent of many classic and much-admired compressors of yesteryear. The compressors timing can be controlled automatically (Auto mode) or dramatically altered using the wide-ranging and fully variable attack and release controls. A built-in three-position high pass sidechain filter has also been included for enhanced low-frequency control.
The limiter section is a peak detecting hard-knee style, its control signal being taken from the output of the Effect level pot. Limiting ranges from approximately 25dB down to 4dB. With a little experimentation, many severe and colorful compression effects are possible. This section also includes its own three-position high-pass sidechain filter.
Both sections can be independently linked to other AM-10 units the compressor uses true power summing when linked, while the limiter section uses greater-of-two peak response when linked.
Separate 7-element LED meters monitor gain reduction and output level simultaneously.
The AM-10s mix section is comprised of two controls: a level control for the gain cell and a Dry signal level control, giving the ability to blend varying amounts of dry and compressed signals together at the output.
