Dual Lowpass Mode:
The Voyager XL Dual Lowpass filter mode features
two lowpass filters which are routed to the left
and right audio output, creating a stereo effect. The
CUTOFF knob controls the frequency cutoff of
both filters. The filters can be set to the same cutoff
frequency, or adjusted to different cutoff frequencies
using the SPACING control. When the two filters 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 filters identically.
Highpass Lowpass Mode:
In Highpass/Lowpass mode, the Voyager XL filters
are configured as a lowpass and highpass filter in
series, resulting in a bandpass filter. The output of the
bandpass filter is routed to both outputs. As with the
Dual Lowpass mode, the CUTOFF control changes
the cutoff frequency of both filters, and the SPACING
control sets the frequency difference between the
highpass filter and lowpass filter. The spacing between
the two filters creates a variable passband. In this mode,
the RESONANCE control affects only the lowpass filter,
thus making for some distinctive and usual filter sounds.
The Voyager XL has two voltage controlled filters (VCF’s) that can be configured either as dual lowpass
filters or as a combination of highpass & lowpass through a front panel switch. Additionally, the cutoff slope
of each filter can be changed in software, resulting in a wide range of unique and interesting sounds.
