API 565

The 565 Filter Bank module has circuits that are true to the musical filters of the famed 215 module found in large format API consoles.

• Sweepable low-pass filter (500Hz to 20kHz, -6 or -12dB slope)

• Sweepable high-pass filter (20Hz to 400Hz, -12 or -18dB slope)

• Variable notch filter with adjustable Q (fully sweepable between 20Hz and 20kHz)

• Individual bypass switches for each filter section

• Transformer Balanced Output to +28 dBu

• Traditional API fully discrete circuit design

• Uses API 2520 and 2510 Op-Amps as well as the same discrete transistor buffers used in the famous 550 series equalizers
