High-Resolution USB Audio / MIDI Interface (4 in, 4 out)

The four-channel US-4x4HR is a member of the Tascam US-HR series of high-resolution USB audio interfaces and an enhanced version of the popular Tascam US-4x4. It provides four mic / line inputs, two of which can alternatively be used for direct input of a guitar or bass, four balanced line outputs, two headphones connectors, and MIDI I / O to your Windows or Mac computer or your iPhone or iPad*. This interface is ideal for multitrack recording of two instruments and two vocalists, for instance, or multi-media production with high demands on simple operation and studio-quality sound. The included loopback function and support for Open Broadcaster Software (OBS Studio), however, makes it also an excellent choice for two-channel podcast creation and live streaming.

The versatile US-4x4HR incorporates a wealth of features, including high audio resolution up to 24-bit / 192 kHz, ultra-low latency with a Windows buffer size starting at four samples, Ultra-HDDA mic preamplifiers with 48-volt phantom power for superior sound quality with ultra-low noise, a robust USB Type C connector, and a rich assortment of included software to start producing stunning audio right away.

All US-HR models offer a unique dye-cast aluminum honeycomb structure on the side panels with a slight upward tilt. This design not only results in a sleek, eye-catching design, it also provides just the right amount of weight so the interface won't move when cables are connected or disconnected. Equally important, the upward tilt offers the ergonomic benefit of being angled in such a way as to make the interface easy to work with.

With four microphone preamps for multi-mic setups, four configurable balanced outputs, superb sound quality and easy operation, the US-4x4HR is the ideal choice for the demanding musician, producer or home-recordist requiring more than two audio channels.

The Ultra-HDDA (High-Definition Discrete Architecture) mic preamps used on the US-HR series feature a discrete construction. They have a higher number of components and are far away from mass-produced preamps. Their EIN (equivalent input noise) rating, which measures the absence of noise, is truly low for the US-2x2HR and US-4x4HR. Combined with a newly improved audio circuit and support for sampling rates up to 192 kHz, our in-house developed microphone preamplifier delivers enhanced audio performance with the most transparent and low-noise sound, reflected in a signal-to-noise ratio of 110 dB.

One issue when recording using a computer is latency, which is when audio signals are delayed through digital circuitry. Another is setting up the driver software that is used when connecting an audio interface to a computer. In order to eliminate these problems, our driver software introduces only very little latency and is easy to install. Furthermore, by making the external structure of these interfaces as simple as possible, the Tascam US-2x2HR and US-4x4HR allow users who are not expert users of audio equipment to operate them without concern.

The US-4x4HR has four Ultra-HDDA mic preamps. Since up to four condenser mics can be used at the same time, this interface is perfect for recording vocals and acoustical instruments simultaneously. You can also connect two guitars or a guitar and a bass while still having two mic inputs available for vocals.

The unit features four TRS jack outputs, so the individual signals can be output in parallel with the headphones stereo output - often done for multitrack recording. TIP: By using an audio interface to output the sound from a commercial synthesizer app, a richer sound can be achieved.

The Settings Panel, which is installed on your computer, comes with a variety of functions. You can choose whether direct monitoring is done in mono or stereo and adjust the balance between input and computer signals. You can also switch the hardware inputs on and off individually and set the Windows buffer size according to your working environment.

For online broadcasting, Internet communication and other live streaming applications, the US-HR series interfaces offer a Loopback function which can merge input signals 1 / 2 with signals 1 / 2 coming from the computer (each can be set to mono or stereo) and send that mix to the broadcasting or other software on the computer. A software slider allows to adjust the final "broadcast" volume independently from the unit's line output level setting.
