audio technica / AT-UMX3

An audio mixer that can be easily connected to a PC via USB. Equipped with a loopback function, it can also be used for streaming, game commentary, etc. Simple design and intuitive operation. The sound quality is particularly compatible with condenser microphones such as the AT20 series.

・ Design technology and sound quality evaluation unique to microphone manufacturers
Supervised by technical and design personnel who have been involved in microphone development for many years.
We design and evaluate sound quality using microphones such as Audio-Technica's AT2020 as a reference.
・ Enhanced noise resistance with dedicated design
Noise generated from peripheral electronic devices such as smartphones and Wi-Fi routers, and external connections. In order to suppress the influence of noise on audio, we have implemented a mechanical shield design using a special filter circuit and metal plate to achieve clean distribution that is resistant to noise.
・ Neutrik XLR/φ6.3mm combo jack is used as the microphone terminal.
- Can supply stable 48V phantom power
・ Hi-Z input terminal that allows you to directly connect an electric guitar, etc.
・Uses high-performance A/D converter of up to 192kHz/24bit
Adopting a high-performance A/D converter with a maximum sampling frequency of 192kHz and a maximum bit rate of 24bit, it is possible to stream at a high resolution comparable to that of a recording audio interface. Outputs the sound of microphones and instruments input into the mixer with clear, high-quality sound.
- Can be used immediately by plug-and-play to PC, smartphone, or tablet*
Compatible with USB class compliant, no special driver installation required.
You can use it immediately by simply connecting it to a device that has a USB Type-CTM terminal. It also comes with a USB cable and USB conversion adapter, so it can be connected to devices with USB Type-A terminals.
*When connecting to a smartphone/tablet, connect the smartphone/tablet to the USB terminal and then connect a commercially available USB power adapter to the USB power terminal to supply power.

・Supports distribution on major distribution platforms
It is compatible with not only Windows and MacOS, but also iOS, iPadOS, and Android OS.
Operation has been confirmed* with major live streaming apps and online chat apps.
*Operation with the app is not guaranteed.
・Direct monitor that allows you to monitor your voice and performance without delay
By monitoring on analog circuits, you can monitor your voice or instrument sound without delay during distribution or recording.
・LOOPBACK function convenient for mixing during live streaming
This is useful when playing BGM on a stream or distributing game sounds from a PC. You can mix the sound source on a device connected digitally (USB IN) with the sound of a microphone or instrument connected to the mixer's analog MIC input or LINE input, and output it from USB OUT.
・Easy to understand control panel
The volume of each microphone input, LINE input, and USB input can be adjusted individually. You can change the audio balance to the optimal level not only before streaming but also during live streaming.
- Microphone mute function that allows you to focus on the sound you want to broadcast
While playing background music during a live broadcast, you can instantly mute unnecessary sounds that you don't want your listeners to hear, such as coughing or delivery chimes, with the touch of a button.
- Microphone monitor mute function that allows you to adjust the sound to be monitored
Sound input to the microphone that can be heard from headphones connected to the main unit. During live streaming, you can mute only this input sound from the headphones. For example, if your voice is a nuisance or you don't want to hear it while streaming a game, you can mute your voice so it won't be heard through the headphones.
