Tascam US-4x4HR High-Resolution USB Audio/MIDI Interface
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-4×4. 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.
Lower noise and distortion – better sound than ever
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.
Features:
- Advanced version of our popular US-4×4 with even better sound quality
- Provides four audio inputs and four audio outputs as well as a MIDI interface to a Windows or Mac computer or iOS device
- Audio resolution up to 192 kHz / 24 bit
- USB Audio Compliance 2.0 for iOS connection
