band.
10.
High Shelf On/Off.
Enables/disables the high shelf EQ. When the Shelf button is not engaged, the
High band is a parametric EQ. Enabling the Shelf button turns the High band into a high shelving EQ
that alters, by a fixed amount, a band of high frequencies at and above a user-selected shelving fre-
quency.
Power User Tip
:
A high shelving EQ is like a treble-control knob on a stereo. In this mode, the Center Fre-
quency control selects the shelving frequency.
Passive Program EQ
1.
On/Off.
Turns the EQ on or off in the signal chain.
2.
Low Boost.
Sets the level of boost applied around the chosen low frequency. This control interacts
nicely with the Low Attenuation control, allowing for boosts in apparent bass energy while keeping
overall bass energy within optimal limits.
3.
Low Attenuation.
Sets the level of attenuation applied around the chosen low frequency.This control
interacts nicely with the Low Boost control, allowing for boosts in apparent bass energy while keeping
overall bass energy within optimal limits.
4.
Low Frequency Select.
Sets the center frequency of the band covered by the Low Boost and Low
Attenuation controls.
5.
High Bandwidth.
Sets the Q (or width) of the effect of the high EQ band.
6.
High Boost.
Sets the level of boost applied around the chosen high frequency.
7.
High Attenuation.
Sets the amount of attenuation applied in a shelving fashion to frequencies at and
above the chosen high frequency.
8.
High Frequency.
Sets the center frequency of the high EQ band.
9.
Attenuation Select.
Sets the frequency at and above which the High Attenuation control attenuates
treble content.
