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.
