Cursor Buttons 
The cursor buttons are used to select parameters and options on the 
LCD. The selected parameter or option appears highlighted. 
The [ 
à 
] and [ 
¨ 
] cursor buttons move the cursor left and right, and 
the [ 
¹ 
] and [ 
  
] cursor buttons move the cursor up and down. 
Cursor buttons are also used to position the cursor in a name when 
naming mix scenes, user effects programs, user EQ programs, and 
user dynamics programs. They are also used to select LCD functions 
listed on the UTILITY and MIDI LCD function menus.
When a display left or right icon appears at the left or right side of the 
display, indicating that another display is available, the [ 
à 
] and [ 
¨ 
] 
cursor buttons are used to select the display. 
PARAMETER Wheel 
The PARAMETER wheel is used to adjust the parameter selected 
using the cursor buttons. Its detented action gives it a positive feel, 
allowing quick and accurate parameter adjustments. Turning it clock-
wise increases the selected parameter value, or turns the parameter 
ON. Turning it counterclockwise decreases the selected parameter 
value, or turns the parameter OFF. The faster you turn it, the faster 
the parameter value changes.
The PARAMETER wheel is also used to scroll through mix scenes, 
effects programs, EQ programs, and dynamics processor programs. 
When naming mix scenes, user effects programs, user EQ programs, 
and user dynamics programs, the PARAMETER wheel is used scroll 
through the available characters. 
ENTER Button 
The [ENTER] button is used to confirm settings made using the 
PARAMETER wheel and to toggle two-option parameters such as EQ 
ON/OFF and Effect ON/OFF. It is also used to access LCD functions 
listed on the UTILITY and MIDI LCD function menus.

SEL Buttons 
The [SEL] buttons are used in conjunction with the LCD functions. 
To perform an action on a channel, first select it using a [SEL] button, 
then choose a function using the function buttons to the left of the 
LCD. This form of editing is similar to computer word processing. 
First, you select your text, then execute a function. 
The input channel, stereo input channel, and stereo output [SEL] 
buttons select their respective channels. The RTN/SEND [SEL] but-
ton, on the other hand, is used to select RTN1, RTN2, SEND3, and 
SEND4. Pressing it repeatedly cycles through the options in the fol-
lowing order: 
RTN1—>RTN2—>SEND3—>SEND4—>
When SEND3 and SEND4 are used as a stereo pair, SEND3 and 
SEND4 are selected together. The order then becomes: 
RTN1—>RTN2—>SEND3-4—>
RTN1, RTN2, SEND3, and SEND4 are selected automatically when 
the corresponding [SEND] button is pressed. For example, pressing 
[SEND1] selects RTN1 and pressing [SEND3] selects SEND3.
When a channel is selected, its [SEL] button LED lights up and its 
name appears in the SEL CH area of the LCD. Stereo-pair channels 
are selected together. The channel currently selected by the 
RTN/SEND [SEL] button is indicated by the highlighted arrow head 
at the right side of the LCD.

Phantom Power 
Phantom power provides a +48V DC power source for condenser 
type microphones. It is applied to XLR input channels 1 through 8. 
The PHANTOM MASTER switch on the rear panel is used to turn it 
ON and OFF. Phantom power is applied simultaneously to all eight 
inputs. It cannot be set for individual inputs.
With phantom power set to ON, non-phantom powered micro-
phones, dynamic microphones, and balanced line-level sources can 
still be connected to inputs 1 through 8. However, be careful with 
unbalanced sources.  
Pad 
The Pad function attenuates input signals by 20dB. This is useful 
when inputting high level signals that overload the input preamp. By 
increasing the effective range of the GAIN control, high-level signals 
can be adjusted accurately. Pad can be set individually for the 16 input 
channels. The PAD switch at the top of each channel is used to turn 
it ON and OFF: switch up for OFF, down for ON.  
Gain 
The GAIN controls are used to optimize the input channel signal lev-
els. Use them with the METER LCD function, which shows the input 
signal levels. Ideally the level should be set relatively high and it’s OK 
for it to reach CLIP   
occasionally  
. If CLIP is reached often, however, 
back off the GAIN control a little, otherwise signal distortion may 
occur. The GAIN control should be set with some care, because if it 
is set too low, the S/N performance will suffer, and if it is set too high, 
unpleasant signal clipping and distortion may occur.

1. Press [METER]. 
The METER LCD function 
appears. 
2. To turn the Peak Hold func-
tion ON and OFF, press 
[ENTER] or use the PARAM-
ETER wheel.
3. Use the [ 
à 
] [ 
¨ 
] cursor but-
tons or press [ENTER] to 
switch between the two 
METER displays. 
Metering 
ProMix  01 features comprehensive signal level metering. Input chan-
nels, the stereo input channel, RTN1, RTN2, SEND3, and SEND4 are 
all metered using the METER LCD function. The stereo output is 
metered using the dedicated 12-segment LED meters. Peak hold is 
available for all meters.
The METER LCD function consists of two displays. One shows the 
16 input channels. The other, the stereo input (ST IN), RTN1, RTN2, 
SEND3, and SEND4. Both displays are shown below.
The Peak Hold function can be turned ON and OFF on either display. 
Peak hold levels are cancelled when Peak Hold is turned OFF or 
another LCD function is selected. The stereo output meter peak hold 
is not affected when other LCD functions are selected.  
The following table lists the meter signal source points. 
When the stereo output meter’s 0dB LED lights up, the DIGITAL REC 
OUT still has 20dB of headroom. 
Note:  
It’s OK for signal levels to reach CLIP occasionally. If CLIP is 
reached often, however, back off the GAIN control a little, otherwise sig-
nal distortion may occur.

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 15dB LED lights up, 
which is 5dB before the CLIP LED.

Phase 
The Phase function reverses the polarity of the hot and cold feeds in 
a balanced input (i.e. pins 2 and 3). The phase can be set for the input 
channels and stereo input channel. It can be used to compensate for 
incorrectly wired cables and connectors. It is also useful, for example, 
when a snare drum is miked top and bottom. In this case the bottom 
microphone signal needs to be phase reversed. 
Shown below is the PHASE LCD function. 
The parameters are: 
N 
  
—  
normal phase. 
R 
  
—  
reverse phase.
Stereo-pair channels are controlled together, as shown below.

EQ 
ProMix 01 EQ is three-band fully parametric, with variable Q, fre-
quency, gain, and ON/OFF parameters. Initially the EQ is configured 
as a conventional three-band EQ, with shelving-type low and high 
and peaking-type mid. However, high and low can also be configured 
as peaking types. EQ can be applied to the inputs channels, stereo 
input channel, RTN1, RTN2, and stereo output. Stereo-pair input 
channels are controlled together.
Shown below is the EQ LCD function. The top-half shows the EQ 
response curve, the bottom-half, the EQ parameters. The vertical dot-
ted line indicates the frequency of the selected band. 
EQ parameters are:
Q is stated in musically intuitive octave values. The following table 
compares octave values with conventional decimal Q values.

EQ Library 
The EQ library is used to store EQ settings. Settings are stored as EQ 
programs, and there are 30 preset programs (1–30) and 20 user pro-
grams (31–50) for you to store your own EQ settings. When STORE 
is selected on the LIBRARY LCD function, user program 31, the first 
user program, is selected automatically. You cannot select preset pro-
grams 1 through 30 while the STORE option is selected. User EQ pro-
grams can be named for easy identification.
Shown below is the LIBRARY LCD function. The response curve of 
the selected EQ program is shown to the right. Library programs are 
listed in the center and the name of the EQ program last recalled or 
stored is highlighted. Also there is an equal symbol (=) between the 
program’s name and number, not a period like the other programs. 
The PARAMETER wheel is used to scroll through the program list. 
When another program is selected, its name flashes. If it is recalled, 
it stops flashing, appears highlighted, and the period between its 
name and number changes to an equal symbol (=).
