A USB Audio Mixer for Live Streaming by a Microphone Manufacturer


Recently, streaming has become popular not just on PCs but also on smartphones, allowing anyone to start easily at any time. Live streaming, where people share their hobbies or their own content such as games, art, and music, and interact with other users in real-time, has garnered interest. To support users new to streaming, Audio-Technica has designed a compact and feature-rich USB audio mixer. The AT-UMX3 is an ideal tool for both beginners and experienced streamers, providing high-quality sound both at your desk and on the go.


AT-UMX3: Usage Image


There's no need to worry about equipment setup for your first stream. It's usable without the need for dedicated drivers, and it features two types of LINE inputs: one that supports Hi-Z input and one for stereo, allowing you to mix instrument sounds with microphone audio for streaming. For example, it's possible to connect a guitar or keyboard for "singing while playing" or "cover song" streams. Additionally, it comes with a Loopback function that allows you to mix input sounds with sounds played on the device for streaming. With Loopback turned on, you can stream with background music or simultaneously broadcast game sounds and voices.


This USB audio mixer, the first of its kind from Audio-Technica supervised by microphone design experts, is equipped with features necessary for live streaming, offering easy operation for beginners and a compact size that won't trouble you for storage space.
