WELCOME TO THE WORLD OF MOOGERFOOGER
ANALOG EFFECTS MODULES!
Your MF-104M Analog Delay 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-104M 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.
Housed in a rugged steel and hardwood enclosure, your MF-104M
Analog Delay features an all-analog signal path. Its finely-tuned frequency
response and overload contours produce the sound quality of the best
vintage delay devices.
The MF-104M Delay Line incorporates a dual-range Bucket Brigade
Device (BBD) providing a range of delay times from 40 milliseconds to
800 milliseconds. A multi-waveform Low Frequency Oscillator (LFO)
enables you to create a variety of effects including chorus, pitch shifting,
and vibrato by modulating the Delay Line.
Several of the performance parameters are voltage-controllable. This
means you can use expression pedals like the Moog EP2, a MIDI-to-CV
converter or any other source of control voltage, such as Moogerfoogers
to play your MF-104M.
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 effects box, your Analog
Delay is much more versatile. Its sound quality and versatility is higher than
most fixed-function “stomp boxes” you may be accustomed to. You will
find that your Analog Delay is a deep electronic musical resource that
offers a very large range of analog sound processing possibilities.

GETTING STARTED
Let’s get started by unpacking and setting up your MF-104M. Here are
some simple instructions on how to plug in and try your new MF-104M.
Guitar or Instrument Expression Pedal
Power Supply
Unpacking
1. Remove your new Moogerfooger from the packaging and allow it a few
moments to get its land legs after the long journey to its new home.
2. Inside the box you’ll find your Analog Delay, AC adapter, warranty card,
and this manual. Save the box in case you ever need to ship your MF-104M
back to Moog Music.
3. Don’t forget to register your Analog Delay. Why? Moog is constantly
updating its products. The only way to know about an update is by
registering. The easiest way is by visiting: www.moogmusic.com/register
Connecting
1. Connect an instrument cable from your sound source to the AUDIO IN
jack on your MF-104M. You can feed virtually any instrument or line-level
signal through your MF-104M.
2. If you plan on using MIDI, connect a MIDI cable from the out on the MIDI
controller of your choice to the MF-104M’s MIDI IN.
NOTE: The Analog Delay defaults to MIDI Channel one. Make sure your MIDI controller
is transmitting on M IDI Channel one.
3. Connect an instrument cable from the MIX OUT jack to a line-level input
on your amp or mixer.
4. Using the supplied power adapter, plug the cord into the +9V jack. Then,
plug the power adapter itself into a wall receptacle.

5. Once the power supply is plugged in your Moogerfooger is ready to
work. You’ll notice that the BYPASS indicator is red. This indicates the
effect is OFF.

THE MF-104M FRONT PANEL
The FRONT PANEL of the MF-104M Analog Delay contains the
performance controls and LED indicators.
MF-104M
ANALOG DELAY
LFO CONTROLS (RIGHT PANEL):
LFO - Six-position rotary switch selects the LFO wave shape for delay
time modulation. Select from Sine, Triangle, Square, Ramp, Sawtooth, and
Sample and Hold modulation.
LFO RATE - Adjusts the LFO rate from 0.05 Hz to 50 Hz (wider range
available via control voltages and MIDI).

DELAY LINE CONTROLS (LEFT PANEL):
TIME - Adjusts delay times from 40ms to 400ms in Short mode and 80ms
to 800ms in Long mode.
RANGE - Selects between Short and Long delay times and bright or dark
filter. The Short setting is brighter while the Long setting is darker.
FEEDBACK - Provides continuous control from no feedback to greater
than infinite. NOTE: Feedback settings above 8 can cause the unit to self-oscillate.
LEVEL CONTROLS (CENTER PANEL):
DRIVE - Allows 35 dB of adjustment of the input signal for optimum signal
path, level matching and overdriving sound sources.
LFO AMOUNT - Controls the amount of LFO modulation of the delay time.
NOTE: More details on these controls can be found on page 17.
THE MF-104M BACK PANEL
The BACK PANEL has all the connection points for sending audio signals in
and out, control voltage inputs, MIDI input, and power supply connector.
AUDIO IN
MIX OUT DELAY OUT
AUDIO IN - 1/4” TS jack. Accepts any instrument level to line level
audio signal.
MIX OUT - 1/4” TS jack. Adjustable output level for instrument or line
level output.
DELAY OUT - 1/4” TS jack. Supplies wet-only output.
FEEDBACK, TIME, LFO RATE, MIX, LFO AMOUNT - All are 1/4” TRS
jacks that accept Moogerfooger EP-2 (or equivalent) expression pedals,
or 0-5VDC control voltages from either two-circuit (TS) or three-circuit
(TRS) 1/4” jacks.
FEEDBACK INSERT - Supplies line-level send and return via a 1/4” TRS jack
for inserting effects into the feedback loop of the Delay line
MIDI IN - Accepts a 5-pin DIN input for controlling the MF-104M via MIDI.

OUTPUT - Allows gain and attenuation of output signal for compatibility
with a wide range of input devices.
MIX - Crossfader control for blending wet and dry signals to the output.

1. Turn your amp or monitor on, then, turn its volume control
down but not off.
2. On the MF-104M, turn all controls except the MIX and
OUTPUT LEVEL to their far left position. Turn the MIX knob to
12:00 and the OUTPUT LEVEL to 9:00 as shown in Figure 1.
3. Press the BYPASS switch so the BYPASS LED turns green
(Figure 2). This means the effect is ON. If you press and hold
the BYPASS switch, you’ll see the LED change from red to
orange or green. Orange or green indicate that the effect
is on but in different modes. For now we’ll focus on Normal.
•NORMAL MODE – Green LED
•SPILLOVER MODE – Orange LED
•OFF – Red LED
4. While playing your instrument (or signal source) turn the
DRIVE control clockwise as in Figure 3 until the LEVEL
LED stays green with occasional orange flashes on peaks.
Note: Red indicates clipping - this is OK if you want to use the Drive
control to add some distortion.
5. Tap the BYPASS switch until the BYPASS indicator is red.
This means the effect is OFF (bypassed).
6. Play your instrument or source again. Then adjust the
OUTPUT LEVEL control until the overall volume with the
effect on and with the effect bypassed is the same. You may
have to switch the effect off and on a few times and make
small adjustments. Once you find the sweet spot keep those
knobs set to maximize fidelity and signal-to-noise ratio.
Since we know you are eager to start hearing what your Analog
Delay can do, let’s dig in, learn a little, and hear how the Delay
Line and LFO work together to create some amazing sounds.
FIGURE 2
DIGGING IN
As you already know by now the MF-104M has a Delay Line and a LFO.
To demonstrate how they work we’ll first check out the Delay Line with
the LFO off. Next, we’ll go over the LFO with the Delay Line at the
minimum setting. Then, we’ll put them together to create some magic.
NOTE: It only seems like magic. In actuality it’s some serious know how on the part
of Moog’s product design team.
GETTING TO KNOW THE DEL AY LINE
As you go through this section, adjust controls as shown in
the illustrations on the right side of the page to hear how different Delay Line settings affect the audio output.
Adjust the Delay Line settings as shown in Figure 4 then
play your instrument. That’s the classic “slapback” echo.
Now increase the FEEDBACK control to 5 and play your
instrument again. You’ll hear a fast series of decaying echoes.
As you increase the FEEDBACK more of the delayed
signal gets sent back through the Bucket Brigade Device
which means a longer series of repeats.
Adjust the settings again as shown in Figure 5 and start
jamming. There’s that slapback again but the delayed sound
is darker (has less treble). Now increase the FEEDBACK to 5.
Play while listening to the echoes and you’ll really notice the
difference, even if your ears are a little cooked from a recent
overdose of decibels.
Your Analog Delay was designed with an area of overlap in
the SHORT and LONG delay ranges, with the SHORT range
having a higher frequency response. This provides the ability
to fine tune the tonal characteristics of the delayed sound
(see Figure 6).
