Introducing the Atlas Sound Indoor/Outdoor Analog Wall 3x1 Mic/Line/BT/AUX Mixer W/Optional Dante® Audio Network Interface WTSD-MIX31K, a versatile 3x1 Mic/line/Aux/Bluetooth Analog Mixer designed to deliver exceptional audio performance and flexibility. This mixer offers a balanced microphone/line input, an auxiliary 3.5mm input, and Bluetooth connectivity, all summed to a balanced line output.

Equipped with commercial-grade Bluetooth technology, the WTSD-MIX31K ensures ultra-low noise levels, long-range connectivity, and convenient features such as no auto-connect and a quick disconnect bump feature. Installers can customize the Bluetooth Discovery ID name using the dedicated renaming app.

Switching between mic or line level for the XLR input is easily done via a front panel switch, accessible through a pinhole. The high-gain mic inputs feature user-enabled phantom power for condenser microphones, along with a 125Hz low-cut filter to eliminate unwanted low-frequency interferences. A local mute button allows for muting the output to the bus, while the system priority button can mute building-wide background music (BGM) systems, isolating the room as needed. Additionally, the adjustable VOX (Voice-Activated Switching) feature mutes the AUX input background audio when announcements are present, ensuring clear and uninterrupted communication.

The AUX input, provided through a stereo 3.5mm jack, is electronically summed to achieve optimal audio performance. Separate level controls for each input allow precise control over the audio mix, enabling the desired balance.

The WTSD-PWBOB is included with each unit, offering a balanced audio output with signal, mute, system priority, and power LEDs. Additionally, it provides a 12V DC logic output for remote system muting or power sequencing.

For enhanced versatility, the WTSD-MIX31K can be converted into a Dante® Digital Network audio mixer by integrating it with the optional AtlasIED TSD-DAC2i converter. This enables seamless integration into Dante® networked audio systems, expanding the mixer's capabilities and compatibility.

Experience exceptional audio quality, flexible control, and seamless connectivity with the WTSD-MIX31K Analog Mixer. Whether for professional installations, venues, or broadcasting applications, this mixer delivers reliable performance and comprehensive features to meet your audio needs.
