1

 SIG indicators

The SIG indicators light green when signals (of at least −32 

dBFS) are input through the IN1/IN2 jacks (and US-4x4 IN3/

IN4 jacks).

2

 PEAK indicators

The PEAK indicators light red when signals that are about 

to distort (−1 dBFS or higher) are input through the IN1/IN2 

jacks (and US-4x4 IN3/IN4 jacks).

3

 GAIN knobs

Use to adjust the input levels of the IN1/IN2 jacks (and 

US-4x4 IN3/IN4 jacks).
Adjust these so that the PEAK indicators do not light red.

USB indicator

This lights when the USB connection is working.

5

 LINE OUT knob 

Use to adjust the output level of the LINE OUT jacks.

6

 PHONES knob

Use to adjust the output level of the PHONES jack.

CAUTION

Before connecting headphones, minimize the volume with 

the 

PHONES

 knob. Failure to do so might cause sudden loud 

noises, which could harm your hearing or result in other 

trouble.

7

 Phantom power switch/indicator

Use this switch to p48V phantom power to the IN1/

IN2 jacks (and US-4x4 IN3/IN4 jacks).
The indicator lights when the phantom power switch is set 

to +48V.

CAUTION

• 

Set the

 LINE OUT

 and 

PHONES

 knobs to their minimum 

values before changing the phantom power setting. 

Depending on the connected mics, sudden loud noises from 

monitoring equipment could occur, and this could damage 

the equipment or harm hearing.

• 

The phantom power switch changes the setting for both 

US-2x2 input channels (all four US-4x4 input channels) 

simultaneously.

• 

Do not connect or disconnect mics when the phantom 

power switch is set to 

+48V

.

• 

Set the phantom power switch to 

+48V

 only when using a 

condenser microphone that requires phantom power.  

Turning phantom power 

+48V

 when a dynamic mic or other 

mic that does not require it is connected could damage this 

unit and connected equipment.

• 

Do not supply phantom power to an unbalanced dynamic 

mic.

• 

Supplying phantom power to some ribbon mics will break 

them. If you are unsure, do not supply phantom power to a 

ribbon mic.

• 

If you connect this unit to a laptop computer that is running 

on battery power and set the phantom power switch to 

+48V

, the computer battery charge will be consumed more 

quickly.

8

 IN1/IN2 (BALANCED/UNBALANCED) jacks

These input jacks are XLR/TRS combo jacks on the US-2x2 

and separate XLR and standard TRS jacks on the US-4x4.
Use the MIC/LINE INST switches on the front of the unit to 

enable balanced line (MIC/LINE) input or unbalanced (INST

input for the standard TRS jacks.
When directly connecting a guitar, bass or other instrument, 

set the MIC/LINE INST switch to INST.

9

 IN3/IN4 (BALANCED) jacks 

These XLR analog mic input and standard line level TRS jacks 

are balanced input jacks.

NOTE

On the US-4x4, the 

IN1

-

IN4

 (

8

9

) inputs each have two 

jacks (XLR and TRS). Do not input signals through both 

jacks of the same input at the same time. If signals are 

input through both at the same time, neither signal will be 

received properly.

0

 MIC/LINE INST switches

Set according to the IN1/IN2 jack input sources.
Set to MIC/LINE when connecting electronic instruments, 

audio devices, mics and similar equipment.
Set to INST when connecting an electric guitar, electric bass 

or other equipment with high output impedance.

q

 MONITOR BALANCE knob 

When recording input signals, use this to adjust the 

monitoring balance between the signals from this unit's 

input jacks and from the computer. 
The volume of signals input through this unit's input jacks 

increase the more the MONITOR BALANCE knob is set 

to the left (INPUT) and signals output from the computer 

increase the more this is set to the right (COMPUTER).
This knob does not affect the recording level of input

signals.

w

 PHONES jack 

Use this standard stereo phone jack to connect stereo 

headphones. Use an adapter to connect headphones with a 

mini plug.
