API 225L Compressor

API: 225L Compressor Features Threshold control from +10 to -20 dBu Variable compression ratio from 1 to infinity Release time constants: continuously variable from .3 seconds to 3 seconds Attack time constants: continuously variable from 1 millisecond to 25 milliseconds "OLD" or "NEW" sound HARD or SOFT compression knee Auto-makeup Gain LED Gain Reduction meter API 2510 and API 2520 op-amps Transformer output to +28 dBu The API 225L Compressor is ideal for all studio, live sound and broadcast applications. Regardless of the threshold or ratio settings, the output level always remains at unity. This unique feature allows for real-time adjustments without the need for changing the output level. Both NEW ("feed forward") and OLD ("feed back") methods are selectable on the front panel, providing two choices of gain reduction. NEW gain reduction is typical of the newer VCA type compressors that rely on RMS detectors for the gain control voltage. OLD or Feed-Back method is what most of th
