9、ith low latency USB port (USB-B type, USB 2.0 standard) Use the included USB cable to connect the unit to a computer. To connect to an iOS device, use a Lightning to USB Camera Adapter made by Apple Inc. CAUTION When using a US-2x2 that is connected to a computer, it will operate using USB bus power

10、. However, the power supply will be insufficient when using the unit connected to an iOS device by USB, so you will need to purchase a separate AC adapter designed for use with this unit (TASCAM PS-P520, DC5V). (When using a US-4x4, always connect the included AC adapter.) A driver is included for u

14、ion in this manual, please refer to the computer operation manual. To use this unit with a computer, dedicated software must be installed on the computer. For details about software installation, see“Installing the dedicated software”on page 6. Conventions used in this manual The following conventio

15、ns are used in this manual. Buttons, connectors and other physical parts of this unit are written using a bold font like this: PHONES knob. Information shown on the computer display is written like this “OK”. Additional information is provided as necessary as tips, notes and cautions. TIP These are

16、tips about how to use the unit. NOTE These provide additional explanations and describe special cases. CAUTION Failure to follow these instructions could result in injury, damage to equipment or lost recording data, for example. Using the TEAC Global Site You can download this Reference Manual and t

19、4 front panelUS-2x2 front panel 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 thro

20、ugh 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. 4USB indicator This lights when the USB connection is working. 5 LINE OUT knob Use to adjust the o

21、utput level of the LINE OUT 1-2 jacks. 6 PHONES knob Use to adjust the output level of the PHONES jack ( 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

22、in other trouble. 7 Phantom 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

23、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 c

24、onnect 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

25、 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 phan

26、tom 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

27、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. N

28、OTE 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/

29、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 adj

30、ust the monitoring balance between the signals from this units input jacks and from the computer. The volume of signals input through this units 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

31、 right (COMPUTER). This knob does not affect the recording level of input signals. TASCAM US-2x2/US-4x4 5 2 Names and functions of parts w PHONES 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 O

32、UT 12 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.

34、r. Use this to input MIDI signals. y USB port Use the included USB cable to connect the unit to a computer. (Supports USB 2.0.) CAUTION When using a US-2x2 that is connected to a computer, it will receive power from the computers USB port. Depending on the computer, the USB port might not be able to

35、 supply enough power to operate the unit. When connected to a USB 3.0 port, it will function in High Speed mode equivalent to USB 2.0 (480 Mbps maximum). After waking a computer from suspend (sleep) mode, if the unit does not operate properly, turn it off and turn it on again or disconnect and recon

36、nect the USB cable. u DC 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 computers USB port, so a dedicated AC adapte

37、r (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). i DC IN 12V connector (US-4x4 only) Connect the included DC12V AC adapter (GPE248-12
