MIDI-to-CV converter, or any other source of control voltages to 'play' your MF-103. While you can use it on the floor as a conventional effects box, your MF-103 is much more versatile and its sound quality is higher than the single fixed-function "stomp boxes"...

Here are some simple instructions on how you can quickly plug in and try out your MF-103. 1. Unpack your MF-103. 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.
6. Now set the MF-103 panel controls as follows (See Figure 2): RATE AMOUNT SWEEP RESONANCE Left Switch Right Switch 6-STAGE Figure 2 - Basic settings for becoming familiar with your MF-103. Press the stomp switch. The BYPASS light will now turn green. Playing your instrument, set the DRIVE control so that the LEVEL indicator lights up yellow most of the time.

Figure 3 - Typical spectrum of a musical sound. A filter, or equalizer, is a signal-modifying device that colors a sound by emphasizing some parts of the audio spectrum and attenuating (cutting down) other parts. In general, a filter or equalizer has a ‘quality’ of its own which is superimposed on the tone color of the original sound.

MF-103. PHASER PARAMETERS The following phaser parameters are under your control in the MF-103: MODE: 6-STAGE or 12-STAGE, selectable by the right-hand rocker switch. OUTPUT: AUDIO (main output), or AUX, each with its own output jack.

The phaser parameters are independent of one another. This means that you can set them in any combination that you wish. There is no such thing as a “wrong” combination of settings of the MF-103, so you can experiment all you like to find new, exciting effects for your music.

Note that neither the DRIVE nor the OUTPUT LEVEL controls affect the strength of the bypassed signal. Figure 10 – Block diagram of the MF-103 , showing panel controls, switches, and jacks. Pedal/control jacks are not shown, but performs the same functions as the control knobs.
MF-103 with external control signal sources in the Technical Information section on Pages 14 and 15. In addition to the four expression pedal inputs, your MF-103 has an LFO output jack and a SWEEP IN jack. The LFO jack may be used as control or audio signal sources to control other voltage-controlled devices, including other moogerfooger analog effects modules.
Rotating Speaker: Feed the AUDIO output to one speaker and the AUX output to another speaker for this rotating speaker simulation. Plug your expression pedal into the RATE control input to use your foot to simulate slowing down and speeding up the rotation.

200 milliamperes, and has the appropriate power connector. If you use a power source other than that which was supplied with the MF-103, be sure that the voltage never exceeds +15 volts. Power sources with voltages in excess of +15 volts may cause serious damage to the MF-103's circuit.

AUDIO and AUX output jacks. Thus, when the phaser is bypassed, the signal levels at the output jacks are the same as what your instrument is producing. However, the MF-103 will not pass an audio signal unless power is applied to it.
You must obtain prior approval and an RMA number from Moog Music before returning any product to us. Wrap your MF-103 carefully and pack it with the power adaptor in its original carton. The warranty will not be honored if the product is not properly packed.
