1. PAD switches 
These switch the input Pad, which attenuates the input signal by 
20 dB. See “Pad” on page 18 for more details. 
2. GAIN controls 
These control the gain of the input preamp. See “Gain” on page 18 
for more details.  
3. LCD 
This is a 240 x 64 dot backlit graphic LCD and it displays the LCD 
functions and their parameter values graphically and numerically. 
4. SCENE MEMORY buttons 
These buttons are used to select, store, and recall mix scenes. See 
“Scene Memories” on page 61 for more details. 
5. Function buttons 
These buttons access the various LCD functions. The name of the cur-
rently selected LCD function is shown in the FUNCTION area on the 
LCD. 
6. SEL buttons 
The SEL buttons are used to select channels. Input channel and stereo 
input channel [SEL] buttons select their respective channels. The 
RTN/SEND [SEL] button, however, is used to select SEND3, SEND4, 
RTN1, and RTN2. Pressing it repeatedly cycles through the four 
options. The currently selected RTN/SEND channel is indicated by 
the highlighted arrow at the right side of the LCD. When a channel is 
selected, its [SEL] button LED lights up. 
7. ON buttons 
These buttons are used to turn channels ON and OFF. Input channel 
and stereo input channel [ON] buttons turn their respective channels 
ON and OFF. The RTN/SEND [ON] button, however, is used to turn 
SEND3, SEND4, RTN1, and RTN2 ON and OFF. You must, therefore, 
use the RTN/SEND [SEL] button to select the RTN/SEND channel 
that you want to turn ON or OFF beforehand. When a channel is ON, 
its [ON] button LED lights up. When a channel is turned OFF, the 
LED goes OFF. 
8. Faders 
These are multifunction controls, which means they are used to con-
trol more than one signal. They’re motorized, too, which means that 
they position themselves automatically when, for example, a mix 
scene is recalled, a number of faders are grouped, or an automated 
mix via MIDI is played back. See “Faders” on page  25 for more details. 
9. CUE/2TR IN switch 
This switch determines the signal source for the monitor output and 
phones. CUE selects the Cue bus, and 2TR IN selects the 2TR IN con-
nection.

10.PHONES LEVEL control 
This is used to adjust the headphone output level.  
11.MONITOR OUT LEVEL control 
This is used to adjust the monitor output level. 
12.LCD Contrast control 
This is used to adjust the LCD contrast. Set it so that the LCD appears 
clear and easy to read. You may need to adjust it again when 
ProMix 01 warms up or when the LCD is viewed from a different 
height or angle.  
13.ENTER button 
The exact operation of this button depends on the selected LCD func-
tion. Essentially, it performs two operations. First, to enter/confirm 
settings made using the PARAMETER wheel. Second, to set param-
eters that have only two options. For example, EQ ON/OFF and Peak 
Hold ON/OFF.  
14.PARAMETER wheel 
This is used to adjust parameter values. Turn it clockwise to increase 
a value, and counterclockwise to decrease it.  
15.Cursor buttons 
These are used to select parameters and options on the LCD. 
16.Stereo output meters 
These 12-segment LED meters display the stereo output levels. See 
“Metering” on page 19 for more details.

1. PHANTOM MASTER switch 
This switch is used to turn the +48V DC phantom power ON and 
OFF. Phantom power is switched simultaneously for input channels 
1 through 8.  
2. 2TR IN 
These are RCA/phono jacks with a –10 dB nominal input level. Sig-
nals input here are fed through to the CUE/2TR IN switch and are 
monitored via the monitor out and headphones. The outputs of a 
2-track master recorder can be connected here for confidence mon-
itoring and playback.  
3. ST IN 
These are unbalanced 1/4 phone jacks with a +4dB nominal input 
level. Signals input here are fed through to the stereo input channel. 
The outputs of an external effects processor, or other device with ste-
reo line-level outputs can be connected here. 
When no plugs are inserted, the 2TR IN signals are fed through to the 
stereo input channel (see above note).  
Note:   
When no plugs are inserted into the ST IN phone jacks, the 2TR 
IN signals are fed through to the stereo input channel. This means that 
you can apply EQ, etc., to the 2TR IN signals. When plugs are inserted 
into the ST IN phone jacks, however, this connection is broken.

4. INPUT (BAL) 
Input channels 1 through 8 have balanced XLR-3-31 type connectors 
for connecting microphones. The nominal input level is –60dB to 
+4dB. They are wired according to the IEC 268 standard: Pin 
1–ground, pin 2–hot (+), and pin 3–cold (–). Phantom powering is 
available for condenser type microphones, and it is set using the 
PHANTOM MASTER switch.
Input channels 9 through 16 have balanced phone jack connectors. 
The nominal input level is –60dB to +4dB. Wiring is sleeve–ground, 
tip–hot (+), and ring–cold (–). They can be used with balanced or 
unbalanced plugs. 
Besides connector type and phantom power, the input circuits for 
inputs 1 through 16 are the same. So with an adaptor cable, inputs 9 
through 16 can also be used with balanced microphones.  
5. POWER switch 
This is a push-type power switch. It’s recessed to prevent accidental 
operation. Press once to power ON; press again to power OFF. 
6. PHONES 
This is a stereo (TRS) 1/4 phone jack. A pair of stereo headphones 
can be connected here for monitoring. The phones output signal 
source is the same as that of the monitor output. The headphone level 
is set using the PHONES LEVEL control. 
7. MONITOR OUT 
These are unbalanced 1/4 phone jacks with a +4dB nominal output 
level. They output the monitor signals, and can be connected to the 
inputs on a monitor amplifier. The monitor signal source is deter-
mined by the CUE/2TR IN switch and CUE modes. The output level 
is set using the MONITOR OUT LEVEL control.  
8. AUX SEND 
These are unbalanced 1/4 phone jacks with a +4dB nominal output 
level. They output the SEND3 and SEND4 signals, and can be used 
to feed external effects processors, foldback amplifiers, or multitrack 
recording equipment. 
SEND3 and SEND4 can be configured as a stereo pair. In this case, 
an additional pan control on each input channel and a balance control 
on the stereo input channel allows input signals to be panned between 
these outputs. See “SEND3-4 Stereo Pair” on page  46 for more details.  
Note:   
Make sure that the balanced devices you connect to the INPUTs 
also use pin 2–hot, pin 3–cold wiring. If they’re wired differently, unde-
sirable phase shifts may occur. Refer to their user manuals for details.

9. STEREO OUT 
These are balanced XLR-3-32 type connectors with a +4dB nominal 
output level. They are wired pin 1–ground, pin 2–hot (+), and pin 
3–cold (–).They output the main stereo signals and can be connected 
to power amplifiers in sound reinforcement applications.  
10.REC OUT 
The ANALOG outputs are RCA/phono jacks with a –10dB nominal 
output level. They output the main stereo signals for recording, and 
can be connected to cassette and other analog recorders. They can also 
be used instead of the XLR STEREO OUTs to connect ProMix 01 to 
your home hi-fi system.
The DIGITAL COAXIAL output is an RCA/phono jack. It outputs the 
main stereo signals for recording, and can be connected to DAT, MD, 
and DCC digital recorders via a 75 ohm coaxial cable. The digital out-
put format is IEC958 (Consumer).  
11.MIDI 
These are standard MIDI IN and OUT connections. They can be used 
to connect a controlling computer or MIDI sequencer for automated 
control. They can also be used for control of other ProMix 01s in a 
multiple system. See “MIDI” on page 79.  
Note:  
When the STEREO OUT XLRs are used with unbalanced con-
nectors, their maximum output level is reduced by 6dB. This means that 
the STEREO OUT signal actually clips when the 12dB LED lights up, 
which is 8dB before the CLIP LED.

An Analog Mixer Analogy
If ProMix 01 had an analog mixer interface, it might look something like this. If you’re familiar with analog 
mixers, you may find this illustration reassuring, and the cross references will certainly help you locate infor-
mation quickly. Remember that ProMix 01 offers a lot more than what’s shown below, i.e., scene memories, 
full MIDI control, two internal effects, three dynamics processors...

ProMix 01 User’s Guide 
About the User Interface 
ProMix  01 user interface is straightforward and easy to use. It consists 
of a large backlit LCD display, four cursor buttons, a detented 
PARAMETER wheel, ENTER button, and the channel [SEL] buttons. 
Each of these are explained in detail in the following sections. Func-
tions without dedicated controls are organized into LCD functions, 
which are selected using the function buttons to the left of the LCD. 
LCD Display 
The large backlit 240 x 64 dot graphic LCD display provides clear indi-
cation of mix settings and operating status. As well as showing param-
eter values numerically, faders and rotary controls are represented 
graphically, so you can actually see pan positions and fader positions. 
In addition, EQ curves are displayed graphically and signal levels are 
metered. The following illustration shows information that is always 
displayed and explains what it means. 
The following table shows what can appear in the FUNCTION, 
MEMORY, and SEL CH areas of the LCD.
