The API Select SR24 is a 2-channel equalizer with 4 bands per channel in a 19", 2U rack chassis. It offers 4 semi-parametric EQs per channel with continuous pots for frequencies and gain. Each channel can also be taken out of the signal path via a relay controlled bypass, for easy A/B comparison.
Design with history
The SR24 is based on the design of the 562 EQ from APSI, a subsidiary of API from the 70s-80s. To this day, the 562 EQ is a popular tool among professional audio engineers, but is becoming increasingly difficult to obtain as it is no longer built. API wants to remedy this situation and launches the SR24, a model that is carefully modeled after the original. The user has two channels of the classic analogue equalizer available in a 2U rack unit.
