4 – Preparation
Connecting with a computer
Use the included USB cable to connect the unit to a computer USB port compatible with 2.0, 3.0 or higher USB specications.
When the USB connection is working, the USB indicator on the front of the unit lights.
ATTENTION
i When operating the US-4x4HR with USB bus power, use a
commercially-available Type-C–Type-C cable to connect it to a USB Type-C port on the computer. If there is a problem with the power supply, the phantom power indicator will blink. In this case, use the included AC adapter (PS-P1220E, DC12 V). (see “Using with an AC adapter” on page 10)
i If you connect this unit to a computer via a USB hub, for
example, bus power could be insucient, and audio signal dropouts, clicking noises and other interference could occur due to the inuence of other USB devices connected to that hub. For this reason, we strongly recommend connecting this unit to a separate USB port. Connecting USB keyboards and mice, however, to the same bus should not be a problem.
Connecting with iOS devices
To connect with an iOS device that has a Lightning connector use a Lightning to USB Camera Adapter* and the USB cable included with this product.
To connect with an iOS device that has a USB Type-C connector, use a commercially-available Type-C–Type-C cable.
* You must obtain a genuine Apple Lightning to USB Camera
Adapter separately.
NOTE
When connected, this unit will not provide power to the iOS device.
Audio connections
Analog audio signals input into this device from mics, guitars, keyboards and other audio equipment can be converted into digital signals and transmitted to the computer via USB. In addition, by connecting speakers (through an amplier if not powered) or headphones to this unit, you can monitor audio signals that are input to this unit and output from the computer.
V
CAUTION
Before connecting audio equipment, set the GAIN, LINE OUT and PHONES knobs to their lowest values. Failure to do so could cause sudden loud noises from monitoring equipment, and this could damage the equipment or harm hearing.
Connecting microphones
Dynamic mics
Connect these to the IN1/IN2 (and IN3/IN4 on US-4x4HR) input jacks on the front of the unit.
Condenser mics
When using condenser mics that require phantom power, connect them to the IN1/IN2 (and IN3/IN4 on US-4x4HR) jacks , and set the phantom power switch to +48V.
When the phantom power switch is set to +48V, the phantom power indicator on the front of the unit lights.
V
CAUTION
Lower the LINE OUT and PHONES knobs before changing the phantom power switch between +48V and OFF. Depending on the connected mics, sudden loud noises from monitoring equipment could occur, and this could damage the equipment or harm hearing.
ATTENTION
i Before connecting condenser mics, turn this unit and all
equipment to be connected o (standby).
i The phantom power switch changes the setting for all input
channels simultaneously (2 inputs on US-2x2HR and 4 inputs on US-4x4HR). Do not set the phantom power switch to +48V when connecting a mic that does not require phantom power.
i Do not connect or disconnect mics while the phantom power
switch is set to +48V. Doing so could cause a loud noise and might damage this unit and connected equipment.
i Set the phantom power switch to +48V only when using
a condenser microphone that requires phantom power. Setting phantom power to +48V when a dynamic mic or other equipment that does not require it is connected could damage this unit and the connected equipment.
i When using condenser mics that require phantom power
and dynamic mics together, be sure to use balanced dynamic mics. Unbalanced dynamic mics cannot be used when phantom power is enabled.
i Supplying phantom power to some ribbon mics could break
them. If you are unsure, do not supply phantom power to a ribbon mic.
i 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.
Connecting guitars
When connecting a guitar or bass directly to this unit, use the IN1 or IN2 jack on the front of the unit and set the MIC/LINE INST switch for that jack to INST.
12 TASCAM US-2x2HR/US-4x4HR

4 – Preparation
Connecting analog record players
The output of an analog record player cannot be connected directly to this unit. To connect an analog record player to this unit, a phono amp and equalizer (or an audio amplier that has phono input jacks) must be connected between them.
Connecting monitor speakers
Connect monitor speakers (powered speakers or an amplier and speaker system) to the LINE OUT (BALANCED) 1-2 jacks on the back of the unit.
Use the LINE OUT knob on the front of the unit to adjust the speaker volume.
Connecting headphones
Connect headphones to the PHONES jack (standard stereo) on the front of the unit.
V
CAUTION
Before connecting headphones, minimize the volume with the PHONES knob. Failure to do so could result in a sudden loud noise that could harm hearing, for example.
NOTE
The same signals are output from both the and jacks of the US-4x4HR.
Using direct monitoring
When the Settings Panel LINE OUT 1-2 or LINE OUT 3-4 setting is Monitor Mix, the MONITOR BALANCE knob and input monitoring without delay (direct monitoring) are enabled.
Use the MONITOR BALANCE knob to adjust the monitoring balance between the signals from this unit’s input jacks and the output signals from the computer.
NOTE
i This setting adjusts the monitoring balance. It does not aect
recording levels.
i When using this function, conrm that the input is not set
as an output (monitoring on, for example) in the DAW or other recording software. Input signals could be added to computer output signals, resulting in the doubling of sounds.
MIDI connections
Connect sound modules, keyboards, synthesizers, drum machines and other MIDI devices to the unit in the following manner.
o If you want to monitor sound from a MIDI device, connect its
audio outputs to the IN1/IN2 (or IN3/IN4 on US-4x4HR) jacks on the front of the unit or use an external mixer.
o You can also use the MIDI IN and OUT connectors on the
back of the unit to send and receive MIDI timecode (MTC). By doing this, you can use an application that supports MTC to synchronize a multitrack recorder (MTR) and MIDI devices.
ATTENTION
i The USB indicator might stay lit even after the connected
computer is shut down. This is because some computers continue to provide power through USB cables even after being shut down.
i When using an audio application, if the “MIDI music playback
(default device)” is set to “Microsoft GS Wavetable SW Synth” in the Sound and Audio Devices Properties Control Panel, MIDI performances can be heard through this unit’s LINE OUT (BALANCED) 1-2 (and 3-4 on US-4x4HR) as well as PHONES jacks.

5 Buer Size (Windows only)
You can adjust the size of the buer used to handle the audio input and output signals transferred to and from the computer.
Smaller buer sizes result in less audio signal delay (latency), but require high-speed processing by the computer.
If the processing cannot keep up, for example, due to other system operations, clicking and popping noises might occur and the audio signal might even drop out.
Increasing the buer size will stabilize operation and suppress negative eects on audio signals, but the delay in audio signals sent to the computer will increase.
You can adjust the buer size used with this unit according to your use conditions.

9 – Troubleshooting
Sound breaks up or there is noise
The processing load on the computer causes sound to break up and noise to occur.
Here are some methods to reduce the load on the computer.
1. A wireless LAN and software running in the background,
including antivirus software, regularly put processing loads on the computer, which can cause sound to break up and other noise.
Stop wireless LAN transmission, antivirus software and other software running in the background when using this unit.
2. Set the buer size (latency) in the audio application that
you are using or in this unit’s Settings Panel to a larger value (Windows only).
NOTE
Consult the maker of the audio application that you are using for methods to reduce its load on your computer.
3. Change the settings of your computer so that they are
