F1 (Studio Filter Preamp)
The F1 uses the same filter typology that we use on our NFP filter preamps.
It consists of two separate filters; on one side the filter can sweep between 50Hz and 6Khz and you can select between Low-Pass and Hi-Pass.
The second filter sweeps between 120Hz and 4kHz and you can select between Low-Pass and Band-Pass.
On both you can increase, or decrease, its resonance via the RES controls (one for each Filter) and make it sound fairly flat or boosted by increasing amounts.
A PAN (blend) control allows to blend both signals and it is followed by a Master Volume.
The filters range, together with the ability to select the filter type, makes the F1 very useful, both as an effect or as an utility tool whether you are in the studio, or performing live, both with bass and guitar.
Features:
High Headroom: A voltage doubler (internal circuit) doubles the voltage being fed. This makes it possible to have 36v of internal running operation when powering from an 18v supply. {The pedal can be run from 9v to 18v (max)}.
The higher voltage operation significantly increases the headroom and prevents unwanted clipping/distortion, caused by hotter signals).
LO-P and HI-P switch: select between Low Pass or High Pass for the left filter.
Filter Sweep (left): sweep from 50Hz to 6kHz.
RES (left): Increase or decrease the Resonance for this filter.
LO-P and BD-P switch: select between Low Pass or Band Pass for the right filter.
Filter Sweep (right): sweep from 120Hz to 4kHz.
RES (right): Increase or decrease the Resonance for this filter.
PAN: Blend between both filters.
VOL: Master volume for the active signal.
