MFC1 MIDI Foot Controller 
The MFC1 is a MIDI foot controller that can transmit MIDI Program 
Change messages. This could be used with ProMix 01 for recalling 
mix scenes. With the addition of an optional FC7 Foot Controller and 
footswitch, the MFC1 can also transmit MIDI Control Change mes-
sages, which could be used for real-time ProMix 01 parameter 
control.

Input Specifications
*1. Sensitivity is the lowest input level that will produce an output of +4dB (1.23V), 
the nominal output level when ProMix 01 is set to maximum gain (all level controls 
and faders set to maximum).
*2. XLR-type connectors are balanced (1=GND, 2=HOT, 3=COLD).
*3. MIC INPUT phone jacks are balanced (Tip=HOT, Ring=COLD, Sleeve=GND). 
*4. STEREO IN phone jacks are unbalanced.

A/D converter  
 — An electronic device that converts analog signals 
into digital signals.  
Aliasing  
 — A type of signal distortion that occurs during A/D con-
version if the sampling frequency is less than twice that of the highest 
audio frequency. A/D converters employ aliasing filters to filter out 
audio frequencies higher than half the sampling frequency.

Dynamic mix automation  
 — Mixdown automation where mix 
settings are adjusted in real time.  
Dynamic range  
 — The difference between the loudest and quietest 
signal levels in a system. In an audio device, usually the difference 
between the maximum output level and the residual noise floor. In a 
digital system, the available dynamic range is determined by the data 
resolution, about 6dB per digital bit. Hence, a 16-bit system theoret-
ically provides a 96dB...

Peaking  
 — A type of EQ circuit used to cut and boost a band of fre-
quencies. It produces a mountain-peak type response curve. The 
width of the frequency band is controlled by the Q parameter. Mid-
band EQ is usually of the peaking type.  
 Compare with  
 Shelving.  
PCM  
 — An abbreviation for Pulse Code Modulation. In the second 
part of the A/D conversion, the pulses derived using PAM are con-
verted into binary data words using PCM.

Shelving 
 — A type of EQ circuit used to cut and boost frequencies 
above or below a set frequency. It produces a shelf-looking response 
curve. High and low EQs are usually of the shelving type. ProMix 01 
high and lows, however, can also be configured as peaking types.
