HARMONICS Switches
With the HARMONICS switches you choose the fre-
quency range of the fundamental tone area that should
be processed with the HARMONICS control. There are four avail-
able frequency ranges. For reasons of space, we have rounded fre-
quency values for the front lettering.
Filter 1:
Center Frequency: 9,8 kHz, Bandwidth: 9.6 kHz, Max. Gain: +15 dB
Filter 2:
Center Frequency: 6.6 kHz, Bandwidth: 5 kHz, Max. Gain: +15 dB
Filter 3:
Center Frequency: 2.8 kHz, Bandwidth: 9 kHz, Max. Gain: +15 dB
Filter 4:
Center Frequency: 1.9 kHz, Bandwidth: 4.7 kHz, Max Gain: +15 dB
The frequency ranges are based upon our experiences and test
series to offer ideal processing ranges for a wide variety of instru-
ments (and vocals of course). You may find further information
under „Applications” on page 10.
SATURATION Control
As the name implies, the SATURATION control deter-
mines the degree of the tube saturation. At the most
extreme level this SATURATION control output level
may increase the overall output level by approximately
6 dB.
The SATURATION control offers a wide range of effects intensity
from most subtle to brutal harmonic distortion. Aside from har-
monic tube distortion, the accompanying tube limiting effect
should also be considered. For further details on the saturation
effect refer to the “Introduction” on page 5 and 6.
