Tascam - US-4x4HR
USB audio interface, 4 balanced XLR / jack inputs with low-noise Ultra-HDDA microphone preamplifiers (EIN: -125dBu) and 2 line outputs (6.3 mm jack, balanced). Built-in loopback function and compatibility with OBS Studio (formerly Open Broadcaster Software) make it an excellent choice for creating podcasts and live streaming.
Presentation
The compact US-4x4HR audio interface is packed with features, including high-resolution audio (up to 24-bit/192kHz), ultra-low latency with a Windows buffer size starting at 4 samples, Ultra-HDDA mic preamps with 48-volt phantom power for excellent sound quality with extremely low background noise, a robust USB-C connector, and a rich collection of bundled software to get you started with audio production straight away.
