EQ Display: The heart of the Programmable EQ is the 7-band graphic

equalizer display. The LED display shows the currently active settings of

the equalizer within a range of +/-18 decibels (dB) for each of the seven

accessible bands. The left and right arrow buttons select the frequency

band to be adjusted and the main encoder knob adjusts the level of the

selected band up or down. The center frequency (in Hz) of each band is

indicated at the bottom of the display.

Band Select Buttons:

The band select buttons ﬂank the display and are

indicated by left and right arrows. Press a corresponding button to select

a higher or lower frequency to be edited.

Note: The equalizer can be quickly “zeroed” by pressing the left and right

arrow buttons simultaneously.

Encoder:

The main knob on the unit is an encoder style control that

allows incremental up or down level changes to the selected frequency

band in 1dB steps. The maximum range is +18dB and the minimum is

-18dB for each frequency band.

SELECT Button:

Pressing the select button will scroll through the

four user presets. The display will update to show the saved equalizer

curve and output for each preset location. Also, the four LEDs above

the SELECT button will indicate which of the four presets is currently

selected.
