2U SUB & UPPER BASS PREAMP
SUB SECTION
INPUT
Controls the gain of the whole preamp giving enough headroom for the rest of the stages in the preamp.
4 BAND EQ
4 bands of specially selected frequencies to hit the sweet spots in any enclosure.
When fully anti-clockwise each frequency is FLAT & gain is added as you turn them up.
PARAMETRIC EQ
Sweepable peaking EQ with switchable bandwidth. When button is out the Q is narrow & when pushed in the Q is wider.
Just like the previous EQ stage, when the gain is fully anti-clockwise, the frequency is not boosted.
LF CONTOUR
A specially designed filter has now been implemented into the Bass Preamp allowing you to tailor your sub enclosure with frequency & damping controls to the sound you desire.
FILTER/CROSSOVER
The crossover section of the Bass Preamp has both variable high and low pass sections.
The high pass button allows to select one of the two 24dB/Oct Butterworth filters switchable between 35Hz when the button is out and 27Hz when pushed in
The low pass control is a fully variable 24dB/Oct filter allowing you to sweep between 40Hz - 100Hz with an additional Q control allowing you to shape the low pass to virtually any filter available.
PHASE BUTTON
This push-button allows a reverse phase of 180 degrees when pushed in
