HF Freq This parameter determines the HF band center frequency to
be boosted or attenuated by the band Gain setting. The
available range is 1.5 kHz to 18 kHz.
HF Gain This control determines the amount by which the frequency set-
ting for the HF band is boosted or attenuated. The available
range is ±20 dB.
HF Hi-Q Enable The filter slope of the HF band can be changed with this control.
When Hi-Q is off, the Q is 0.7. When Hi-Q is active, the Q is 2.
Higher Q values mean the peak (or trough) has steeper slopes.
Hi-Q is active when the button is gray and the yellow indicator illuminates. Hi-
Q is off by default.
Note: Hi-Q has no effect when the band is in shelf mode.
HF Shelf Enable The HF band can be switched from bell mode to shelving mode by
clicking the shelf enable button. Shelf mode is active when the but-
ton is gray and the yellow indicator illuminates. Shelf is off by de-
fault.

boosted or attenuated by the HMF Gain setting. The available
range is 800 Hz to 9 kHz.
