Dual Lowpass Mode:
The Voyager’s Dual Lowpass mode provides two
identical lowpass fi 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 fi lters. The fi lters can be set to the same cutoff
frequency, or adjusted to different cutoff frequencies
using the SPACING control. When the two fi 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 fi lters identically.
Highpass/Lowpass Mode:
In Highpass/Lowpass mode, the Voyager’s fi lters are
confi gured as a lowpass and highpass fi lter in series,
resulting in a bandpass fi lter. In this confi guration, the
output of the fi lter is routed to both outputs. As with
the Dual Lowpass mode, the CUTOFF control changes
the cutoff frequency of both fi lters, and the SPACING
control sets the frequency difference between the
Highpass fi lter and Lowpass fi lter. The spacing between
the two fi lters creates a variable passband. In this mode,
the RESONANCE control affects only the Lowpass
fi lter, thus making for some terrifi cally interestingly fi lter
sounds.
The Voyager has two voltage controlled fi lters (VCF’s) that can be confi gured either as dual lowpass fi lters
or as a combination of highpass & lowpass through a front panel switch.
