What is a Phaser? - 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.
What is a
12-Stage Phaser? -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.
Features
- RATE
- rotary control, which varies LFO's frequency over a 250:1 range.
- AMOUNT - rotary control, which adjusts the amount by
which the LFO output varies the phaser sweep.
- SWEEP - rotary control, which moves the phaser
frequency response over a six-octave range.
- RESONANCE - rotary control, which adjusts the height and
sharpness of the peaks of the phaser frequency response.
- DRIVE - rotary control, which adjusts the gain of
the audio input to the phaser.
- OUTPUT LEVEL - rotary control, which balances the phaser
signals with the bypassed signal.
- LO-HI - rocker switch, which chooses between the low
LFO range (0.01 Hz to 2.5 Hz) and the high LFO range (1.0 Hz to 250 Hz).
- LEVEL - a three-color LED that is used to set the
DRIVE control.
- LFO - a LED that indicates the LFO rate.
- BYPASS - a two-color LED that tells whether the
phaser is active or bypassed.
- ON/BYPASS - a rugged, smooth-acting stomp
switch..
Jack Panel Features
- AUDIO IN - 1/4" phone jack - accepts any
instrument-level or line-level audio signal from -16 dBm to dbm. Input
impedance is one megohm.
- AUDIO OUT - 1/4" phone jack - -4 dBm nominal output
level. dBm absolute maximum output level. Output impedance is 5,000
ohms.
- AUX OUT - 1/4" phone jack - -4 dBm nominal output
level. dBm absolute maximum output level. Output impedance is 5,000
ohms.
- RATE, AMOUNT, SWEEP, RESONANCE -all of which are stereo 1/4" jacks that
accept moogerfooger EP1 (or equivalent) expression pedals, or control
voltages from two-circuit or three-circuit 1/4" jacks.
- SWEEP IN
- provides a means
of applying an external 2.5 volt control signal to the second 6-section
phasing circuit, in place of the LFO. Input impedance is 50,000 ohms.
- LFO OUT - 1/4" phone jack - delivers the LFO waveform
(triangular wave; 2.8 volts) for use by other voltage-controlled
devices. Output imedance is 600 ohms.
- POWER INPUT - jack - accepts standard 9 volt
power adaptors (power adaptor included).
