INDOOR/OUTDOOR ANALOG WALL 3X1 MIC/LINE/BT/AUX MIXER W/OPTIONAL DANTE

The AtlasIED WTSD-MIX31K is an indoor/outdoor analog wall mixer built around three balanced microphone/line inputs, a front-panel 3.5mm auxiliary input, and Bluetooth connectivity. Its 3×1 configuration brings multiple audio sources together in a wall-mounted format, while the WTSD Bus output provides the specified connection to the wider WTSD system. Optional Dante support adds a network-audio path when required.

Ideal Use Cases

This model is suited to indoor or outdoor audio locations that require accessible wall-based control of several source types. The three balanced microphone/line inputs accommodate systems that need multiple wired audio feeds, while the front-panel 3.5mm connection provides a convenient local music input. Bluetooth connectivity supports another source option without occupying the wired auxiliary input. Because Dante is optional, the mixer can be selected for an analog WTSD installation or specified where Dante network-audio integration is part of the system design.

Why Choose This Model

The WTSD-MIX31K combines microphone, line, auxiliary, and Bluetooth source connectivity in one wall mixer. Its music input is a front-panel 3.5mm stereo connection with stereo signals summed for the mixer. The listed auxiliary input specification is 1V (0dBV), unbalanced, with 10kΩ impedance. Balanced line input level is specified at 500mV (-6dBV). This range of available inputs gives the model a clearly defined role when a single wall location must manage both installed audio feeds and locally connected sources.

For microphone support, the mixer includes defeatable 24VDC phantom power. A red front-panel indicator shows when phantom power is on, while the associated DIP switch is located on the rear panel. A separately defeatable 125Hz/12dB low-cut filter provides another installer-configurable input function.

Installation and Integration

The mixer measures 4.37 inches high by 4.34 inches wide by 2.5 inches deep, with corresponding metric dimensions of 111mm by 110mm by 62.6mm. Its listed product weight is 0.53 lb (0.24kg), and its shipping weight is 1.3 lb (0.61kg). These dimensions and weights provide concrete planning information for the intended wall installation.

The specified output type is WTSD Bus, and the listed connector type is an XLR female socket. Installer-adjustable phantom power and low-cut filter switches are positioned on the rear panel, so their required settings should be established during setup. Dante capability is optional rather than stated as standard, making its inclusion an installation-level decision. No mounting accessories, Dante interface components, power requirements, or included-box contents are identified in the supplied product data.

Performance Highlights

The WTSD-MIX31K has a stated frequency response of 20Hz to 20kHz within ±1dB. Total harmonic distortion is specified at 0.06% at 1kHz. The balanced line input level is 500mV (-6dBV), while the unbalanced auxiliary input is rated for 1V (0dBV) with 10kΩ impedance. These published values make it possible to evaluate source compatibility and the mixer’s stated audio performance before integration.

The 125Hz/12dB low-cut filter can be defeated when filtering is not required. Likewise, the 24VDC phantom-power function can be disabled for sources that do not need it. Both functions use rear-panel DIP switches, with the phantom-power status also represented by a red front-panel indicator.

What Makes It Different

The defining feature of this model is its combination of three balanced microphone/line inputs with two convenient local source options: a front-panel 3.5mm stereo-summed input and Bluetooth connectivity. It retains an analog WTSD Bus output while offering optional Dante capability for projects that call for network audio. That combination distinguishes the WTSD-MIX31K as more than a single-source wall input and gives it a focused 3×1 mixing role.

Final Assessment

The AtlasIED WTSD-MIX31K is a practical choice when the specified design calls for an indoor/outdoor analog wall mixer with three balanced microphone/line inputs, local auxiliary audio, and Bluetooth. Its published 20Hz–20kHz response, defeatable phantom power, defeatable low-cut filter, WTSD Bus output, and optional Dante capability provide a detailed foundation for system planning. The 36-month warranty from the date of purchase completes the supplied specification set.
