Moog Music MF-101 Lowpass Filter - Manual (Page 11)

TECHNICAL INFORMATION
NOTE: The following information is intended for use by people who understand analog electronic circuitry
and have enough practical experience to interconnect sophisticated electronic equipment correctly.
POWER: The MF-101 works satisfactorily on +9 to +15 volts DC and uses about 100
milliamperes of current. If your power adaptor shows up missing or inoperative, you
can power your MF-101 from any other power adaptor with a +9 volt or +12 volt rating
and with the same power connector.
If you use a power source other than that which was supplied with the MF-101, be
sure that the voltage never exceeds +15 volts. Power voltages in excess of +15 volts
may cause serious damage to the MF-101's circuit.
PEDAL INPUTS: All pedal control input jacks are 1/4" tip-ring-sleeve phone jacks. The
sleeves are grounded and the ring terminals are supplied with +5.7 volts which is
current-limited to about 0.5 milliamperes. The tip terminals receive the variable voltages
from the pedals.
Correct wiring of an expression pedal for the MF-101.
An expression pedal for use with the MF-101 should contain a 50KW or 100KW
potentiometer which is connected from the sleeve to the ring terminals. The
potentiometer wiper is connected to the tip terminal. The pedal cable should be
shielded, with the shield connected to the sleeve terminal.
