WELCOME TO THE WORLD OF MOOGERFOOGER
ANALOG EFFECTS MODULES!
Your MF-104M Analog Delay is a rugged, professional-quality instrum ent,
designed to be at home on st age or in the studio. Its great sound and jawdropping effects come from state-of-the -art analog circuitry, designe d
and handcrafted by our team at Moog M usic in Asheville, Nor th Carolina.
The MF-104M is rooted in the a nalog wizardry of Bob M oog’s Moogerfooger designs. It is a direct descendent of th e original M oog® modular
synthesizers and professional rack ef fects .
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 produ ce the sound q uality of the best
vintage delay devices.
The MF-10 4M 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 Freque ncy Oscillator (LFO)
enables you to create a variety of effect s including chorus , pitch shifting,
and vibrato by modulating the Delay Line.
Several of the perform ance parameters are voltage- controllable. This
means you can use expression pedals like the Moog EP 2, a MIDI-to-CV
converter or any other source of control voltage, such as Moo gerfoogers
to play your MF-10 4M.
In addition, the front panel rotary controls and switch es can be controlle d
through th e use of MIDI and the LFO can be synced to a MIDI Clock.
While you can use it on the floor like a conventional effec ts box, your Analog
Delay is much m ore versatile. Its soun d quality a nd versatilit y is higher than
most fixed-function “stomp boxes” you may be accustomed to. You will
find that your Analo g Delay is a deep e lectronic musical resource that
offers a ver y large range of analo g sound processing possibilities.

Unpacking
1. Remove your new Mooger fooger f rom the packa ging and allow it a few
moments to get its land le gs after the long journ ey 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 M usic.
3. Don’t forget to r egister your Analog Delay. Why? Moog is cons tantly
updating its pr oduct s. The on ly way to know about an update is by
regist ering. The easiest way is by visiti ng: www.moogmus ic.com/register
Connecting
1. Connect an instrument ca ble from your sound source to the AUDIO IN
jack on your MF-104M. You can feed virtually any instr ument or line-level
signal through your MF-104M.
2. If you plan on using MIDI, connect a MID I cable from the out on the M IDI
controller of your choice to the MF-104M’s MIDI IN.
NOTE: The An alog Delay defaults to M IDI Chan nel one. M ake sure you r MIDI contro ller
is transmit ting on MI DI Chann el one.
3. Connect an instrument ca ble from the M IX OUT jack to a line-level in put
on your amp or mixer.
4. Using the supplied power adapter, plug the cord into the +9V jack. Then,
plug the power a dapter itse lf into a wall receptacle.
NOTE: The M F-104M requires a power supply o f +9VDC , CENTE R POSIT IVE, rate d for
at least 40 0mA .
5. Once the power supply is plugged in your Mooge rfooger is ready to
work. You’ll notice that the BYPASS indicator is red. This indicates th e
effect is OFF.

LFO CONTROLS (RIGHT PANEL):
LFO - Six-position rotary switch sel ects the LFO wave shape for de lay
time modul ation. Select from Sine, Triangle, Square, Ram p, Sawtooth, and
Sample and Hold modulation.
LFO RATE - Adjusts the LFO rate from 0.05 Hz to 50 Hz (wider range
available via control voltage s and MIDI).
LFO AMOUNT - Controls the a mount of LFO modulation of the delay time.
NOTE: More d etails on the se controls c an be found o n page 17.

SETTING LEVELS
1. Turn your amp or mo nitor on, then, turn its volume control
down but not of f.
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 an d the OUTPU T 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 ef fect is ON. If you pre ss and hold
the BYPASS switch, you’ll see the LED change from red to
orange or gree n. Orange or green indicate that the effect
is on but in diffe rent modes . For now we ’ll foc us on Normal .
•NORMAL MODE – Green LED
•SPI LLOVE R MODE – Orange LED
•OFF – Red LED
4. While playing your instr ument (or signal source) turn the
DRIVE control clockwise as in Figur e 3 until th e LEVEL
LED stays green with occasional orange flashes on pe aks.
Note: Red in dicates cli pping - this is OK if you want to use t he Drive
control to ad d some disto rtion.
5. Tap the BYPASS switch until the BYPASS ind icator is red .
This means the effec t is OFF (bypassed).
6. Play your instrument or source again. Then adjust the
OUTPUT LEV EL control until the overall volume with the
effect o n and with the ef fect bypassed is the same. You may
have to switch the effe ct off and on a few times an d make
small adju stments . 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 Analo g
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.
If you really n eed some instant gr ati fic ati on s kip to pag e 13
for som e great s etups.
GETTI NG TO KNOW THE D ELAY LINE
As you go through this section, adjust controls as sh own in
the illustrations on the rig ht side of the page to hear how different Delay Line settings affect the audio output.
Adjust the Delay Line settings as shown in Fi gure 4 then
play your instrument. That’s the clas sic “slapback” echo.
Now increase the FEEDBACK control to 5 and play your
instrume nt again. You’ll hear a fast series of decaying e cho es.
As you increa se the FEEDBACK more of the delayed
signal gets sent back through the Bucket Brigade Device
which means a longer se ries of repeats.
Adjust the set tings again as shown in Figure 5 and st art
jamming. There’s that slapback aga in 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 th e
difference, even if your ea rs are a little co oked from a rece nt
overdose of decibels.
Your Analog Delay was designed with an area of overla p in
the SHORT and LONG delay ranges , with the SHORT range
having a higher frequency respon se. This provid es the abilit y
to fine tune the tonal characteristics of the delayed sound
(see Figu re 6).

DIGGING IN
As you already know by now the MF-1 04M has a Delay Line and a LFO.
To demonstrate how they work we’ll first check out the De lay Line with
the LFO of f. Next, we’ll go over the LFO with the Delay Lin e at the
minimum setting. Then, we’ll put th em together to create some magic.
NOTE: It only s eems like ma gic. In actuality it ’s some ser ious know how o n the part
of Moog’s p roduct des ign team.
