SHERMAN FILTERBANK2
Instrukcja Obsługi

Suppose you want all frequencies to pass (Lp + Bp + Hp): set the Lp Bp Hp balance on Bp and the correction knob halfway -Bp+LpHp. This gives following calculation : Bp + 0.5(-Bp+Lp+Hp) = Bp - 0.5Bp + 0.5Lp + 0.5Hp = 0.5Bp + 0.5Lp + 0.5 Hp = 0.5(Bp + Lp + Hp) You can make up for the weaker output with more input. Fiddle around with these knobs until you know what to expect from them ! By turning the input level up, the sound will start to distort, with more harmonics being added at the input stage. Always remember that too much input can push away the resonance peaks, giving you the impression that the resonance knobs don't work properly. Try it out, it's one of the features you should be very familiar with; on the thin line between producing an over-the-top distorted racket and a noisy sound with low dynamics, the FB works best. It's up to you to find the right equilibrium. Keep in mind that you always can adjust the balance between the processed signal and the original signal, or compare them with the Bypass-Effect knob.
HI BOOST

In low frequency settings, a weak high �eee� sound can occur. This is perfectly normal and typical for the Filterbank. Don�t worry, it�s not broken. It�s mainly audible as as crossing over between both filters. When the harmonics switch is not in the �free� position, the �eee� sound in filter �1�, caused by freq of filter �2� can be avoided by increasing the frequency of filter �2� a bit, as this filter �2� setting is not significant anyway. If you want to work in this sub bass range, the "eeee" can be easily suppressed by turning down the hi eq on you mixing console. LOWEST FREQUENCY RANGE Our warning �Dangerous frequency range� is not a joke. Speaker coils can actually burn when they move too slow, and have lack of ventilation. This can happen at high volume and unhearable low frequency. The FB can easily produce frequencies below 1 Hz. The bottom frequency can change in different environment temperatures. This is a disadvantage of this analog system, the price to be payed for an extreme range. By inside adjustment, this bottom frequency can be changed. To do this, you must open the Filterbank and look for the trim holes marked �F1� an �F2�. With a tiny screwdriver, you can re-adjust the bottom frequency of each filter to your needs. Please don�t touch any other trim holes !

The 3-way switch

HI CUT

on the input stage allows Hi boost

(effective at low input level) as well as Hi cut effective at high input level)
SENSITRIG

The 3-way switch

LIMIT

allows "Sensitrig" (which makes the

triggering twice as sensitive for, e.g. clean string pad filtering) and "Limit", which leaves the filters more �breathing room� for selfoscillation if the input stage is extremely overdriven.
