Critic Reviews

API The Channel Strip Review

mixonline.com

API's The Channel Strip packs a punch with its seamless integration of classic 500 Series modules into a convenient rackmount format. The 512C preamp, 527 compressor, and 550A EQ deliver stellar sound quality, making it a versatile tool for any studio. The extensive I/O and routing options enhance its flexibility, allowing simultaneous use of its components. However, the auto-gain makeup in the compressor can be excessive, and the blue markings may be hard to read under certain lighting. Despite these minor flaws, it's a must-have for those seeking robust, reliable audio processing.

This is all I’ve got now; I used to have racks of stuff. I record vocals, guitar and bass into an Apple MacBook Pro through a signal chain comprising little more than the Antelope Eclipse 384, an API Channel Strip and a Shure microphone.
