500 Series discrete filter set
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 sectionTransformer Balanced Output to +28 dBuTraditional API fully discrete circuit designUses API 2520 and 2510 Op-Amps as well as the same discrete transistor buffers used in the famous 550 series equalizers
