Dual Lowpass Mode:
The Voyager’s Dual Lowpass mode provides two
identical lowpass  lters which are routed to the left and
right audio outputs respectively, creating a stereo effect.
The
CUTOFF
knob controls the frequency cutoff of
both  lters. The  lters can be set to the same cutoff
frequency, or adjusted to different cutoff frequencies
using the
SPACING
control. When the two  lters are
set at different cutoff frequencies and routed to two
different speakers, what you hear can be a fantastically
swirly and vocal sound – similar to a phaser effect. In
Dual Lowpass mode, the
RESONANCE
control affects
both  lters identically.
Highpass/Lowpass Mode:
In Highpass/Lowpass mode, the Voyager’s  lters are
con gured as a lowpass and highpass  lter in series,
resulting in a bandpass  lter. In this con guration, the
output of the  lter is routed to both outputs. As with
the Dual Lowpass mode, the
CUTOFF
control changes
the cutoff frequency of both  lters, and the
SPACING
control sets the frequency difference between the
Highpass  lter and Lowpass  lter. The spacing between
the two  lters creates a variable passband. In this mode,
the
RESONANCE
control affects only the Lowpass
 lter, thus making for some terri cally interestingly  lter
sounds.
The Voyager has two voltage controlled  lters (VCF’s) that can be con gured either as dual lowpass  lters
or as a combination of highpass & lowpass through a front panel switch.
