6 Description of Effects
6.1 Hall, Room, Plate
These three effects are used to create a natural rever-
beration . The reverb decay time and the brightness
of the effect signal are adjustable with the control
FX VARIATION (5) (
Hall simulates the reverberation in a large hall . It is
characterized by long early reflections and a soft,
long reverberation . This effect is often used for solo
instruments and lead vocals .
Room simulates the reverberation in an empty room
of medium size . It is characterized by short and dis-
tinct early reflections and a short reverb decay time .
This effect is ideal for percussion instruments .
Plate simulates the sound of a reverb plate . In the
past, reverb plates were used in studios to create
artificial reverberation . They provide a reverberation
with emphasis on the high frequencies . There are
no early reflections so that information concerning
the size of the room is missing and the sound of the
effect is somewhat artificial . This reverberation is
often used for solo instruments and vocals .
6.2 Vocal, Gate
These reverb effects do not simulate natural acous-
tics; they are used to create special effects .
Vocal simulates the reverberation in a large hall,
however, with the addition of small echoes to
improve the characteristics of vocals . The reverb
decay time and the brightness of the effect signal
are adjustable with the control FX VARIATION (5) .
Gate (gated reverb) simulates a reverberation that
is cut off by a noise gate when the reverb signal falls
below an adjustable value instead of slowly decay-
ing . This effect is ideally suited for percussion instru-
ments of very short sound, e . g . snare drums and kick
drums . The reverb decay time and the gate threshold
are adjustable with the control FX VARIATION .
6.3 Echo, Delay
The MFX-16M offers two echo effects for various
applications:
Echo: This effect is ideally suited for vocals . It creates
echoes with a different delay time in the left and
right stereo channels . The delay time is adjustable
with the control FX VARIATION (5) .
Delay: For this classic echo effect, the number of
echoes is adjustable with the control FX VARIATION .
To define the delay time, briefly press the button
TAP/ F1 (6) [at least 4 times] . The interval between
the last two actuations will define the delay time
(1 .3 sec . max .) . To synchronize the beat of the

echoes, press the button TAP/ F1 several times to
the beat of the music .
The green LED above the button TAP/ F1 will
flash at an interval corresponding to the delay time
adjusted .
6.4 Chorus, Flanger, Phaser, Tremolo, Rotary
These effects are modulation effects, i . e . the input
signal is modulated (e . g . in its pitch) and mixed to
the original input signal . Depending on the type of
variation, various effects will result .
Chorus: This effect is used to make an instrument
or a voice sound "richer" . To obtain this effect,
part of the input signal is delayed (approx . 30 ms),
the pitch is slightly varied all the time (vibrato) and
mixed to a part of the original input signal . The fre-
quency of the vibrato is adjustable with the control
FX VARIATION (5) .
Flanger: The Flanger effect was originally created
when the same piece of music was played simulta-
neously on two tape decks and the output signals
of the units were mixed . Since the two units were
not completely in sync due to tolerances, increasing
time differences would result between the signals .
When the signals of the tapes were mixed, various
frequencies sweeping across the frequency spectrum
would cancel each other due to the variations in
speed . From the acoustic point of view, you get the
impression of a jet plane flying through the music .
Slowing down a tape reel ("flange") would system-
atically increase the intensity of this effect . The speed
of the frequency cancellations is adjustable with the
control FX VARIATION .
Phaser: The distortion in sound typical of the Phaser
is created when the phase of a part of the input
signal is shifted and mixed to a part of the original
input signal . The control FX VARIATION defines the
phase shifting speed . The effect is mainly used for
guitars, electric pianos and keyboards .
Tremolo: A tremolo is created when the volume of
a signal is modulated . The effect is ideally suited for
guitars, bass guitars and keyboards . The speed at
which the volume is modified is adjustable with the
control FX VARIATION .
Rotary: This effect simulates rotating speakers (Leslie
effect) . The effect became popular in the era of the
Hammond organ for which it was mainly used . Today
it is also often used by guitarists .
For the simulated rotation of the speakers: Press
the button BYPASS / F2 (8) or actuate a footswitch
connected to the jack FOOTSWITCH (13) to stop
(LED above the button BYPASS / F2 lighting up) and
restart (LED not lighting up) this effect . The "rotating
