Low
Coils additionally produce a more pleasant harmonic spectrum, which is
especially important for the precision and tangibility of bass sounds.
The Sub Bass filter is exceptionally suitable in presenting voluminous and
powerful deep bass sound and produces a fat bass layer. In combination
with the Low filter extensive possibilities for processing of bass sounds are
provided. This way it is possible to produce a beautiful bass layer with the
Sub Bass filter into which frequency-selected accents – using the Low filter –
can be interspersed. Instruments provided with such processing give a
powerful bass foundation with clear definition; impure bass equalization is
eradicated.
Low
The Low filter spans the frequency range of 10 to 250 Hz (Frequency
control).It can be described as a decisive low band filter that in distinction to
many comparable concepts deals exclusively with the low tonal range and
in this manner can be utilized very accurately and with high sensitivity.The
maximal amplification or reduction (Cut/Boost control) of the selected
frequency is +/- 15 dB.
The Q factor can be varied from 0.5 to 5Q with the Bandwidth control. A
lower Q factor determines a larger bandwidth at the selected frequency,
whereas a greater Q factor defines a smaller bandwidth.
Please read the information about proportional-Q principle of the filter and
the recommendation of setting of bandwidth on page 8.
