Filter, Frequency and Range Controls

FILTER FREQ Slider: Sets the filter frequency within its operating range. When no envelope or LFO signals are

present, the frequency of the filter is set by the position of this slider. To perform a manual

filter sweep, simply push this slider up or down.

RANGE Switch: Changes the sweep range of the filter:

LOW position gives the filter a sweep range from 150 Hz to 5 kHz.

HI position gives the filter a sweep range from 350 Hz to 12 kHz .

OVER/UNDER RANGE LEDs: Indicates that the filter is being swept to its limits of the frequency range.

OVER RANGE RED LED: Indicates the frequency has been swept to or above

the maximum range of the filter.

UNDER RANGE YELLOW LED: Indicates the frequency has been swept to or

below the minimum range of the filter.

FILTER MODE Switch: Selects the type of filter characteristic:

LP: Low Pass Mode turns the filter into a Low Pass filter which only passes audio below the

cutoff frequency. With no envelope or LFO modulation, the cutoff frequency is set by the

FILTER FREQ slider and RANGE switch.

BP: Band Pass Mode turns the filter into a Band Pass filter which only passes audio in the

region around the center frequency. With no envelope or LFO modulation, the center fre-

quency is set by the FILTER FREQ slider and the RANGE switch.

HP: High Pass Mode turns the filter into a High Pass filter which only passes audio above the

cutoff frequency. With no envelope or LFO modulation, the cutoff frequency is set by the

FILTER FREQ slider and RANGE switch.

Q Slider: Adjusts the filter’s quality factor or “Q”, also known as resonance. With this slider you have control of the

filter’s “peak” from a flat roll-off curve to a highly emphasized peak at the cutoff or center frequency. The higher the

control setting, the greater the peak of the filter, which will produce a more pronounced filter effect.
