API 565

API 565 500-Series Discrete Filter Set

• 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
