The Controls and Connectors
English
The Controls and Connectors
Front Panel
Mixer section
[HI-Z INPUT 1] button
This button switches the HI-Z on ( 0)/off ( /) 
for the analog input jack 1. When directly con-
necting an electric guitar or electric bass that 
has passive pickups and no built-in preamp to 
the analog input jack 1,  turn the [HI-Z] button 
on. 
NOTE
• Use an unbalanced phone cable when you connect  an electric guitar or electric bass and turn the [HI-Z] 
button on. If you use a balanced cable or an XLR 
cable in such a case, this device will not work cor-
rectly.
• If no device is connected to analog input jack 1, turn  this button off. Otherwise noise may occur.
 [MONO] button
This button allows analog  input jacks 1 and 2 to 
be used either as separate mono channels or as 
a stereo pair. When the button is on ( 0), analog 
input jacks 1 and 2 function as independent 
mono channels feeding both the L and R LINE 
OUT jacks. It is used to monitor the sound of 
the microphone or guitar connected to the ana-
log input jack 1 in the center of the monitor 
speakers. When the button is off ( /), analog in-
put jack 1 and 2 function as a stereo pair: the 
analog input jack 1 signal feeds the L LINE 
OUT jack and the analog input jack 2 signal 
feeds the R LINE OUT jack. Switching this but-
ton on/off does not affect the signal sent to the 
computer.

The Controls and Connectors
English
INPUT 1/2 GAIN controls/PEAK 
Indicator
Adjusts the input signal  level. The signal that 
has passed through the GAIN control will be 
sent to the computer. To achieve the best bal-
ance of the recording level between S/N ratio 
and dynamic range, adjust the level so that the 
PEAK Indicator lights only occasionally and 
briefly on the highest input transients.
 [PHANTOM INPUT 1&2] button/
Indicator
This button switches the phantom power 
(+48V) on ( 0)/off ( /). If you turn the button 
on, the CI2+ supplies phantom power to the an-
alog input jack 1 and 2 (XLR-type). The indica-
tor lights when the button  is turned on. Turn this 
button on when using a phantom-powered con-
denser microphone.
CAUTION
• Make sure that phantom power is turned OFF un- less it is needed.
• When turning phantom power ON, make sure that  no equipment other than phantom-powered de-
vices such as condenser microphones are con-
nected. Devices other than condenser 
microphones may be damaged if connected to the 
phantom power supply. Note, however, that the 
switch may be left on when connecting to balanced 
dynamic microphones. When connecting an unbal-
anced device to the analog input jacks (1/4" phone 
type) and phantom power is turned on, hum or 
noise may result; this is not a malfunction or fail-
ure in the device.
• Do not connect or disconnect a device while phan- tom power is applied. Doing so can damage the 
connected device and/or the unit itself.
• To protect your speaker system, leave the monitor  speakers (powered spe akers) turned off when 
switching the phantom power on/off. It’s also a 
good idea turn all master control and output vol-
ume controls down to minimum. Neglect of these 
precautions may result in large noise bursts that 
may damage your equipment, your ears, or both.
 MASTER control
Adjusts the signal level  sent to the LINE OUT 
jacks. This allows you to adjust the overall vol-
ume without changing the relative volume bal-
ance among the channels. This control does not 
affect the signal sent to the computer.
 PHONES control
Adjusts the signal leve l sent to the PHONES 
jack, since this output signal is not affected by 
the MASTER control.
 MIX control (INPUT—DAW)
Adjusts the signal level balance between the 
signal from the analog input jacks and the sig-
nal from an application software, such as DAW. 
This control does not affect the signal sent to 
the computer.
AI KNOB section
The functions of the AI  KNOB section differ ac-
cording to the mode, Norm al or Browse. Normal 
mode is the conventional mode. When a window 
such as Browse Sounds window in Cubase is 
opened, the mode changes to the Browse mode 
automatically. In Browse mode, you can use the 
button   AI KNOB,   [LOCK] button,  
 [PRE-
VIOUS] button,   [NEXT] button, and  ! [AC-
TION PAD] button to navi gate through Cubase 
windows, e.g. the Browse Sounds dialog. Below 
are the explanations of the function in Normal
