User manual MOOG MF101

[. . . ] After that we'll give you some suggestions on how to use your MF-101 in specific applications. At the end of this booklet you'll find technical specifications, service and warranty information. GETTING STARTED Here are some simple instructions on how you can quickly plug in and try out your MF101. We suggest that you place it on a table while you become familiar with its features. 2. Check that the power adaptor is rated at your country's standard power voltage (120 volts A. C. [. . . ] The SMOOTH-FAST switch determines whether or not the envelope signal is smoothed out. Some sounds (like guitar chords) have long, rough envelopes, and they often sound better if the envelope is smoothed out before going to the filter. Other sounds (like snare drum) are quick and sharp, and sound really good with the switch in the Fast position. The ENV light shows how strong the envelope signal voltage is at any one time. The stronger the audio input, the brighter the ENV light will be. Audio Input Level and Mixing The DRIVE and MIX controls and the LEVEL light are all part of the audio input level and mixing circuitry. With this control you can set the right input gain for virtually any instrument or line-level signal source. Turn this control counterclockwise for strong input signals, and clockwise for weaker sound sources. The DRIVE control is always active, even when the MF-101 is in BYPASS mode. The MIX control crossfades from the straight input signal to the filtered signal. The LEVEL light tells how strong the input signal is after being adjusted by the DRIVE control. As the signal level increases, the light goes from off, to green, to yellow, and finally to red. When the light is green, the signal is below the level that results in audible distortion. When the light is yellow, some low order distortion may be audible, giving the sound a subtle warm analog quality. When the signal is strong enough to drive the light into the red, the distortion at the output becomes stronger and more distinctly audible. Watch this light when you set the DRIVE control for the desired effect. Simplified Block Diagram of the MF-101 EXPRESSION PEDALS AND VOLTAGE CONTROL You now know what each of the rotary control knobs does to the sound of the MF101. With the exception of DRIVE, each knob has an expression pedal input which duplicates its effect. This enables you to plug in up to four expression pedals to play the MF-101 with your feet as well as with your hands. See the Technical Information section on Page 12 for more information on pedal specifications. When you plug an expression pedal into one of the pedal inputs on your MF-101, the pedal adds to the effect of the corresponding control. For example, let's say that you plug an expression pedal into your MF-101's CUTOFF input. With the pedal all the way back, the cutoff frequency of the filter is set by the CUTOFF knob. Then, when you advance the pedal, the cutoff frequency of the filter goes up, just as if you turned the CUTOFF knob up. [. . . ] Then send it to Moog Music (UPS is recommended) with transportation and insurance charges paid.
