Page 6: Fuctions And Operation
Functions and Operation Constant Q and proportional Q modes Each frequency band consists essentially of two fully parametric equalizers: one for constant Q mode and one for proportional (or variable) Q mode, selectable per band. The PQ is the fi rst equalizer to offer both modes, endowing it with double equaliza- tion power for demanding corrective and creative applications. - Page 7 Amplitude Amplitude settings are freely adjustable from -/+ 15 dB in proporional mode and from -/+ 20 dB in constant Q mode. Frequency Each channel provides fi ve fully parametric frequency bands covering 10 Hz to 28 kHz. Each band overlaps its neighbor by one octave and can be independently acti- vated and deactivated.
