    104Z and set the panel controls for the ‘basic’ setup. Next, we'll explain how your MF-104Z works. After that we'll go through the panel features and give you suggestions on how to use your MF-104Z in some specific applications. At the end of this booklet, you'll find technical specifications, service, and warranty information, and information about Moog Music.

  • Page 3: Getting Started

    Here are simple instructions on how you can quickly plug in and try out your MF-104Z. 1. Unpack your MF-104Z. You can place it on a table or on a floor. We suggest that you place it on a table while you become familiar with its features.
  • Page 4 5. Connect an instrument cable from your signal source to the AUDIO IN jack. You can feed virtually any instrument-level or line-level signal through your MF-104Z. Examples are guitar, bass, keyboard, theremin, drum machine, or Effects Send output on your mixer.
  • Page 5 With the FEEDBACK control above 8, the echoes build up chaotically into some amazing electronic textures. In the next sections we'll explain how an analog delay works and look at your MF-104Z in more detail. For now, get a feel for your MF- 104Z's controls by experimenting with different settings.

  • Page 6: What Is An Analog Delay

    The design of your MF-104Z Analog Delay is unique because it combines authentic, finely-tuned vintage analog bucket-brigade delay circuitry with analog-synthesizer-style voltage control of delay...

  • Page 7: Performance Parameter Controls

    This characteristic gives a natural-sounding mix for most music signals. If you're applying a sustained steady pitch to the MF-104Z and the MIX control is set near midposition, you may find that the direct and delayed signals alternately reinforce and cancel each other in rapid succession as the delay time is varied.

    Then, when you switch your MF-104Z on again, a new echo stream will begin to build up. This is a convenient way of `canceling' an echo stream while you're playing.

  • Page 9: The Audio Level Controls

    MF-104Z audio input circuitry. Once you set the DRIVE control as described above, the input level is optimized for best operation of your MF-104Z's circuitry. Do not change the DRIVE setting except to tweak the input level or to compensate for changes in the level of your instrument signal.
  • Page 10 LOOP OUT jack and the LOOP IN jack. Connect the external sound processor and set the LOOP GAIN control as follows: 1. Use patch cords to connect a) the MF-104Z LOOP OUT jack to the Audio In (instrument) jack on your processor, and b) the Audio Out (amplifier) jack on your processor to the MF-104Z LOOP IN jack.

  • Page 11: Audio Outputs; Expression Pedals

    TIME, and FEEDBACK, has an expression pedal/control input which duplicates its effect. This enables you to plug in up to three expression pedals to play the MF-104Z with your feet as well as your hands. The moogerfooger EP-1 Expression Pedal is designed for this purpose or you can use expression pedals with equivalent specifications.

    MIDI-to-CV converters, etc. You will find examples of interfacing your MF-104Z with external control signals on Pages 19-20, and you will find technical information on Pages 17-18. TYPICAL SETUPS Here are a few interesting setups for your to experiment with. Try changing the knobs with your hands.

    The AUX OUT goes directly to one input on your amplifier or mixer, while the main AUDIO OUT goes through the MF-104Z. Thus, the direct sound is not colored, but the echoes swirl because of the phaser modulation.
