Moog MF-108M User Manual

WELCOME TO THE WORLD OF MOOGERFOOGER®
ANALOG EFFECTS MODULES!

Your MF-108M Cluster Flux is a rugged, professional-quality instrument,
designed to be at home on stage or in the studio. Its great sound and jaw­dropping effects come from state-of-the-art analog circuitry, designed
and handcrafted by our team at MOOG Music in Asheville, North Carolina.

The MF-108M is rooted in the analog wizardry of Bob Moog’s mooger­fooger designs. It is a direct descendent of the original Moog® modular
synthesizers and professional rack effects.

Your Cluster Flux offers two basic functions: A dual-range Bucket Brigade

Device (BBD) Delay Line designed for very short delay times and a multi­waveform Low Frequency Oscillator (LFO) capable of modulating the Delay
Line for a variety of effects including Chorus, Flanging and Vibrato.

Several of the performance parameters are voltage-controllable. This means
you can use expression pedals, a MIDI-to-CV converter or any other source
of control voltage, such as other moogerfoogers to play your MF-108M.

In addition, the front panel rotary controls and switches can be controlled
through the use of MIDI and the LFO can be synced to a MIDI Clock.

While you can use it on the floor like a conventional ef fects box, your
Cluster Flux is much more versatile. Its sound quality is higher than most
fixed-function “stomp boxes” you may be accustomed to. You will find that
your Cluster Flux is a deep electronic musical resource that offers a very

large range of analog sound processing possibilities.

GETTING STARTED

1. Unpack your Cluster Flux and gently tap the wooden side pieces of your
new moogerfooger to wake it up after the long journey to its new home.

2. Connect the instrument cable from your sound source to the AUDIO IN jack.
You can feed virtually any instrument or line-level signal through your MF-108M.

3. If you plan on using MIDI, connect a MIDI Cable from the out on the MIDI
controller of your choice to the MF-108M’s MIDI in.

NOTE: The Cluster Flux defaults to MIDI Channel one. Make sure your MIDI controller is
transmitting on MIDI Channel one.

4. Connect an instrument cable from the L/MONO Out jack to a line-level

input on your amp or mixer. Turn the volume control on your amp down but

not off.

5. Using the supplied power adapter, plug the cord into the +9V jack. Then
plug the power adapter itself into a power voltage receptacle.

Note: the CLUSTER FLUX requires a +9VDC rated for at least 300 mA . CENTER

POSITIVE power supply

6. Notice that the BYPASS LED is green. This indicates that the MF-108M’s
effect is on. Red indicates that the effect is OFF (bypassed). Make sure the
Cluster Flux effect is off by pressing the BYPASS switch before continuing.

7. Play your instrument (or signal source). Adjust the volume control on your
amplifier so the sound level is comfortable.

8. Set the MF-108M panel controls to the settings shown in figure 1 to explore
the Flanging effects of the Cluster Flux, or figure 2 to explore the Chorus
effects of the Cluster Flux.

9. Turn on the MF-108M and play your instrument at its maximum level. Set
the DRIVE control so the DRIVE indicator lights up yellow with the peaks of
the input signal. Adjust the OUTPUT control so the Cluster Flux’s effected
signal is about the same loudness as the bypassed signal. You can also use
the OUTPUT as a boost if you like.

10. Low-pitched, sustaining sounds with a bright timbre will work best to

learn the sounds of your new Cluster Flux. Because the Cluster Flux was
designed with far more range control than traditional Flanger and Chorus
devices, you will discover a much larger palette of tones and effects

1. CLASSIC FLANGING

This effect features an up-and-down modu­lation of the input signal. Some describe it
as a whooshing or jet plane sound.

•Move TIME left to raise flanging frequency
and right to lower it

•Try negative FEEDBACK for a lower pitched,
hollow flange

•For best flanging results MIX control should

be mostly wet

•As RATE increases, try decreasing the
AMOUNT for more musical results

2. CLASSIC CHORUS

This effect features a subtle up-and-down
modulation of the input signal’s pitch. With
a 50-50 mix of wet and dry signal, the result
is a lush, swirling tone.

•Longer TIME settings cause a more audible
pitch modulation

• Adding FEEDBACK to a Chorus effect
gives it a metallic edge

•For best results MIX should be set to
center position

•As RATE increases, try decreasing the
AMOUNT for more musical results
