GETTING STARTED

   Here are some simple instructions on how you can quickly plug in and try out your MF-
102.

1. Unpack your MF-102. You can place it on a table or on the floor. We suggest that
you place it on a table while you become familiar with its features.
2. Check that the power adaptor is designed to 9 volts and is rated at your
country's standard power voltage (120 volts A.C. for the United States and Canada; 100

volts for Japan; and 220 volts A.C. for most other countries). Plug the power adaptor's
cord into the MF-102's '+9V' jack. Then plug the power adaptor itself into a power
voltage receptacle.

Figure 1. Basic connections: Instrument to AUDIO IN, monitor amp to AUDIO OUT, and power adaptor to +9V.

3. Note that the BYPASS light is on. It will light up either red or green. Red indicates that
the MF-102's ring modulator is off-line (bypassed), while green indicates that the ring
modulator is on-line. Pressing the 'stomp switch' will toggle the BYPASS light between red
and green. For now, leave the BYPASS light on red.

   Refer to Figure 1 for steps 4. and 5.
4.   Connect an instrument cable from the MF-102 AUDIO OUT jack to a line-level input
of your amp or mixer. Turn the volume control on your amp down but not off.
5. You can feed virtually any instrument-level or line-level signal through your MF-102.

Examples are guitar, bass, keyboard, theremin, drum machine, or Effects Send output
on your mixer. Connect an instrument cable from  your signal source to the MF-102
AUDIO IN jack. Play your instrument (or turn on the signal source). Turn the DRIVE control
clockwise until the LEVEL indicator lights up yellow most of the time.
6. The BYPASS light should still be red. Continuing to play your instrument, adjust the

volume control of your monitor amp until the loudness is comfortable. Your instrument
should sound clean and undistorted.
