Moog MF-103 12-Stage Phaser
The Moog MF-103 12-stage phaser is a
direct descendant of the original Moog modular synthesizers, yet can be used with any instrument
level to line level signal. It contains two compete modular functions: a 6 or 12-stage phaser
with resonance control, and wide range LFO with amount control.
The 12-Stage Phaser's control parameters are Sweep frequency, Resonance, LFO Rate and LFO
Amount. All of these parameters can be controlled by the great feeling knobs that beg to be
tweaked as well as expression pedals or external control voltages. Panel switches select
range of LFO Rate and 6 or 12 stage phasing. 1/4" jacks are provided for audio input and
outputs, pedal/control inputs, LFO out and auxiliary sweep input for bi-phase effects. The
heavy-duty yet smooth-acting bypass switch allows tabletop or floor use.
A phaser is a type of comb filter, so called because its frequency response has several dips
and peaks, like the teeth of a comb. As the phaser response sweeps back and forth across the
frequency spectrum, the harmonics of the audio input signal are alternately increased and
decreased. This produces the classic phaser "whooshing" sound.
Phasing is one of the best ways to impart motion to a track and to make sounds come alive.
With the MF-103 Phaser you can get swirling, shimmering, vibrating effects; fill up a whole
stage from one sound source; even create brand new sonic textures.
The MF-103 produces two comb-filter responses. They are called 6-Stage and 12-Stage, because
of the number of phase-shifting circuits that are used internally. The 6-Stage mode has three
dips in its frequency response, while the 12-Stage mode has six dips. These two modes have
distinctly different sound qualities. In addition, the MF-103 features a variable feedback
circuit which increases the resonance, or depth of the phaser sound. Power supply is included: 110v for use in US or Canada. $299 $20 Optional European
