| Switched LF Shelving filter | -3dB break-frequency tunable from 18 Hz to 360 Hz; maximum reduction -20dB. |
|---|
| Switched CurveShape EQ | +3dB break-frequency tunable from 2.5 kHz to 30 kHz; HF gain adjustable from +0 dB to +18 dB; the slope of the HF filter varies interactively and directly with the CurveShaper™ frequency and gain settings |
