1SIG 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).
2PEAK 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).
3GAIN 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.
4USB indicator
This lights when the USB connection is working.
5LINE OUT knob
Use to adjust the output level of the LINE OUT 1-2 jacks.

to adjust the output level of the PHONES |
1 and |
2 jacks on US-4x4). |
|
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.
7Phantom power switch/indicator
Use this switch to provide +48V 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.
8IN1/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.
9IN3/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.
0MIC/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.
QMONITOR 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.

2 – Names and functions of parts
WPHONES jack
Use this standard stereo phone jack to connect stereo headphones(
1 and 
2 jacks on US-4x4). Each of these jacks outputs the same signal as the LINE OUT 1–2 jacks. Use an adapter to connect headphones with a mini plug.
NOTE
The same signals are output from both the 1 and 2 jacks of the US-4x4.

UDC IN 5V connector (US-2x2 only)
To use this unit when connected to an iOS device, connect a DC5V TASCAM PS-P520 adapter here (sold separately).
NOTE
When using a US-2x2 that is connected to a computer, it will receive power from the computer's USB port, so a dedicated AC adapter (sold separately) should not be necessary.
Depending on the computer, however, the USB port might not be able to supply enough power to operate the unit.
In this case, use a dedicated AC adapter (sold separately).

Installing the dedicated software
To use this unit with a computer, dedicated software must be installed on the computer.
The dedicated software might be updated at any time. Download the latest software for the operating system you are using from the TEAC Global Site (http://teac-global.com/).
iiTo use this unit with a Windows computer, install the included driver. When you install the driver, a Settings Panel application will be installed at the same time.
iiTo use this unit with a Mac, install the Settings Panel application. The standard OS driver will be used.
iiWhen using this unit with an iOS device, the standard OS driver will be used, so there is no need to install dedicated software.
CAUTION
Before starting to install software, quit other applications.
Installing the dedicated driver for Windows
NOTE
•Complete installation of the driver on the computer before connecting the unit to it with the USB cable.
•If you already connected the unit to the computer using the USB cable, and the Found New Hardware Wizard launched, close the Wizard and disconnect the USB cable.
•When you install the Windows driver, the Settings Panel is also installed at the same time.
88 Driver installation procedures
1.Download the latest driver for the operating system you are using from the TEAC Global Site (http://teac-global.com/) and save it on the computer to be used with the unit.
2.Uncompress the saved driver (zip file) on the computer desktop or another location.
3.When uncompressed, separate folders are created for 32-bit and 64-bit versions. To launch the installer software, doubleclick the “US-2x2_US-4x4_ InstallerXX.exe” exe file (“XX” is the number of bits) that is suitable for the OS being used.
CAUTION
If you open a zip file without decompressing it and doubleclick the “US-2x2_US-4x4_Installer.exe” file in the folder that opens, installation will not start. Right-click the zip file and select “Extract All”, for example, to decompress it and then try again.
4.When a “Security Warning” or “User Account Control” screens appear, click the “Run” or “Yes” button.
5.Next, select the desired language and click the “OK” button.
6 TASCAM US-2x2/US-4x4

Working with Gatekeeper
When using Mac OS X, depending on the Gatekeeper security function setting, a warning message might appear during installation.
The solution depends on the warning message shown. See the following explanations for details.
iiWhen the Gatekeeper setting is “Allow applications downloaded from: the Mac App Store”
The following security warning might be shown: “US-2x2_ US-4x4 Installer.dmg” can't be opened because it was not downloaded from the Mac App Store."
In this case, click the OK button to close the message. Then, control-click (or right-click) the file and click “Open”.
Click the “Open” button if the following security warning message appears: “US-2x2_US-4x4 Installer.dmg” can't be opened because it was not downloaded from the Mac App Store. Are you sure you want to open it?"
This warning message might also appear when the Gatekeeper setting is something other than “Allow applications downloaded from: the Mac App Store”.
The security warning message “US-2x2_US-4x4 Installer.dmg” can't be opened because it was not downloaded from the Mac App Store." could appear again, and you might not be able to open the file.
In this case, copy the file from the folder where it is to the desktop or another folder, and then open it. Alternatively, change the Gatekeeper settings to “Allow applications downloaded from: the Mac App Store and identified developers” and try opening it again.
iiWhen the Gatekeeper setting is not “Allow applications downloaded from: the Mac App Store”
‘“US-2x2_US-4x4 Installer.dmg” is an application downloaded from the Internet. Are you sure you want to open it?” might appear as a security warning message. In this case, click the “Open” button.
