Its design incorporates a two-input, two-output 24-bit audio interface with balanced inputs, input inserts, guitar impedance matching, phantom powering, and a 16-channel MIDI interface. Because the US-122 is USB-based, it's the ideal companion to any desktop- or laptop-based digital recording setup. And since it's as compact, like a laptop, requiring no additional power source, it can be combined with one to create a complete portable digital audio workstation solution. Features The input section comprises a 24-bit audio interface, capable of streaming two simultaneous channels of audio into your computer. Inputs include two balanced XLR mic inputs with phantom power capability, two 1/4" balanced line inputs (switchable to high-impedance unbalanced, for direct input of a guitar, bass or other hi-Z source), with TRS inserts on each input channel. Outputs include a pair of unbalanced line outputs on RCA connectors, and a separate headphone output. The US-122 also features MIDI input and output ports, allowing you to send and receive data between your computer and other MIDI-equipped devices. What's in the package The US-122 package contains the following items in addition to the main unit and this manual. When opening the package, please make certain that all the included items are present.

PHONES level control Controls the level to the headphones output. 3 USB indicator Indicates a valid USB connection to the host computer when lit. 4 DIRECT switch Enables/disables direct monitoring of the input signals 5 MONO switch Enables/disables mono output from the direct monitoring system. 2 MIDI IN indicator Indicates presence of incoming MIDI data at the MIDI input. MIDI OUT indicator Indicates transmission of MIDI data from the MIDI output. 6 -- TASCAM US-122 2 ­ Controls and indicators 6 DIRECT MONITOR level control Adjusts the level of the direct monitoring signal, when this is enabled. A PHANTOM switch Switches +48V power to the microphone inputs to allow powering of condenser microphones. NOTE NOTE 7 L and R input level controls Input level adjustment. Rotate clockwise to increase the input level of audio sources. 8 MIC/LINE / GUITAR switches Switch inputs individually between mic/line level and Hi-Z (guitar) level. Only use the phantom powering with condenser microphones which need it. Keep this switch in the OFF position with all other kinds of equipment connected to the XLR inputs. To avoid noise and possible damage to equipment, turn down the input LEVEL controls when switching the phantom power on and off. Also note that this setting consumes power. If you are operating the unit with a battery-powered laptop computer, this will reduce the battery life of the computer. 9 SIGNAL indicators Indicate the presence of an audio signal on the respective channel (specifically, when the input level exceeds -37 dBFS). OL indicators Indicate an overload of the input level to the respective channel (specifically, a level of -2.5dBFS).
