Dual Lowpass Mode:
The Voyager XL Dual Lowpass lter mode features
two lowpass lters which are routed to the left
and right audio output, 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, the resulting sound can vary from
something simple (like a mild phaser effect) to sounding
like two very different synths playing at the same time.
In Dual Lowpass mode, the RESONANCE control
affects both lters identically.
Highpass Lowpass Mode:
In Highpass/Lowpass mode, the Voyager XL lters
are congured as a lowpass and highpass lter in
series, resulting in a bandpass lter. The output of the
bandpass 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 distinctive and usual lter sounds.
The Voyager XL has two voltage controlled lters (VCF’s) that can be congured either as dual lowpass
lters or as a combination of highpass & lowpass through a front panel switch. Additionally, the cutoff slope
of each lter can be changed in software, resulting in a wide range of unique and interesting sounds.
