Product information - API Select SR22

The compressor circuitry of the ATI Paragon Studio consoles

  • 2-channel compressor
  • multi-mono or stereo operation via link circuitry
  • true RMS power summing for stereo operation
  • patented Thrust circuit for full basses and crisp highs
  • ratio, Threshold and make-up gain continuously adjustable
  • analog VU meter (switchable for gain reduction and output level)
  • LED display for overloads
  • Hard- or Soft-Knee switchable
  • balanced XLR and 6.3mm jack inputs and outputs
  • perfect complement to the API SR24 EQ

Circuitry with a history

The API Select SR22 uses the same compressor circuitry as ATI' s Paragon analogue consoles, which merged with API in 1999. Live mixers of this series were to be found on the big stages worldwide for almost 20 years and accompanied a multitude of international artists.

Control options

Threshold, ratio and (make-up) gain can be adjusted continuously per channel. The SR22 offers ratios up to a maximum of 10:1. If used in stereo mode via the link function, the settings of the left channel determine the control behavior. Push buttons can be used to activate the patented Thrust circuit and Hard/Soft knee. Furthermore, the needle of the VU meter can optionally display the degree of level reduction or the output power.

RMS power summing & bypass via relay

For stereo operation, the processing of the left channel is not simply transferred 1:1 to the right channel, but an analog summing takes place beforehand. This way the response of the compressor is influenced by the actual stereo signal and not only by the left channel. In addition, the SR22 has a relay-controlled bypass, which avoids unnecessary signal paths of the clean signal in the unit.

"Thrust" circuit

The patented Thrust circuit activates a filter before the RMS detector that balances the energy level between low and high frequencies, as in typical side-chain applications. This creates a powerful sound that still sounds less compressed.
