electronic circuitry and have enough practical experience to interconnect sophisticated
electronic equipment correctly.
GROWING and SHRINKING TREMOLO
The Envelope control set
at 5 gives a nice tremolo
feel to the effect; the pat-
tern changes gradually
from one lter on to all
lters on, making the tim-
bre feel like it is growing
and shrinking.

POWER: The MF-105 works
on +9 volts DC and uses a max
of about 240 milliamperes of
current. Use only the power
supply supplied with the MF-
105 or the exact equivalent.
Power sources rated with
voltages in excess of +9 volts
may cause damage to the MF-
105’s circuit.
PEDAL INPUTS: All pedal control input jacks are 1/4” tip-ring-
sleeve (stereo) phone jacks. The sleeves are grounded and the ring
terminals are supplied with +5 volts which is current-limited. The
tip terminals receive the variable voltages from the pedals.
