Atlas Sound WTSD-MIX31K – Indoor/Outdoor Wall Mixer with Bluetooth and Dante

Product Overview

The Atlas Sound WTSD-MIX31K is a 3-input analog wall mixer designed for indoor and outdoor commercial audio installations requiring flexible source mixing with optional Dante network audio capability. As an indoor outdoor analog wall mixer with Bluetooth and AUX input, it addresses distributed audio needs in facilities where microphone, line-level, and wireless Bluetooth sources must be combined and routed to a common bus. Long-tail use cases include commercial wall-mount mixer with Dante interface, multi-zone background music controller with priority mute, and outdoor paging mixer with Bluetooth connectivity.

Product Description

The WTSD-MIX31K integrates three input types — a balanced XLR mic/line input, a 3.5mm stereo AUX input, and a Bluetooth stereo input — into a single wall-box form factor rated for indoor and outdoor deployment. The Bluetooth section uses commercial-grade technology with ultra-low noise, long-range connectivity, no auto-connect behavior, and a quick-disconnect bump feature for controlled session management. The Discovery ID can be renamed using the included installer app, making multi-unit deployments manageable. Input selection between mic and line level on the XLR input is made via a front panel pinhole switch. Phantom power (24VDC, defeatable) is provided for condenser microphones, and a 125Hz low-cut filter reduces low-frequency interference. A local mute button silences the output to the bus, while a system priority button enables building-wide BGM muting to isolate a single room. An adjustable VOX function automatically mutes AUX background audio when an announcement is present on the mic input. The included WTSD-PWBOB interface board provides balanced audio output with signal, mute, system priority, and power indicator LEDs, along with a 12V DC logic output for remote muting or power sequencing. Multiple WTSD-MIX31K units can be linked on a shared bus for multi-room systems. For Dante-enabled networks, the unit connects to the optional TSD-DAC2i analog-to-Dante converter, providing IP audio distribution without replacing the analog signal chain.

Key Features

Technical Specifications

Frequently Asked Questions

Q: Can the WTSD-MIX31K be used outdoors?

A: Yes. The unit is designed for indoor and outdoor use. The optional WTSD-COVER water-resistant stainless steel locking cover provides additional protection for outdoor wall-box installations.

Q: Does the Bluetooth input auto-connect to devices?

A: No. The commercial Bluetooth module does not auto-connect, which prevents unauthorized or unintended sources from connecting. A quick-disconnect bump feature allows the installer to manage session control.

Q: How do I add Dante network audio capability?

A: The WTSD-MIX31K interfaces with the optional AtlasIED TSD-DAC2i analog-to-Dante transmitter. This converts the analog balanced output to a Dante-compatible digital audio stream without altering the analog signal chain.

Q: Can multiple WTSD-MIX31K units be linked together?

A: Yes. Multiple units share the same WTSD bus via RJ45, allowing several wall mixers to feed a common downstream system, such as the WTSD-PWHUB receiver with limiter.

Q: What power supply does the WTSD-MIX31K require?

A: The unit ships with the WTSD-PWBOB interface and power supply included. No separate power supply purchase is required.

Q: Can the Bluetooth Discovery ID be customized?

A: Yes. The Discovery ID name is field-customizable using the AtlasIED installer renaming app, which is important for facilities deploying multiple units in adjacent spaces.

Q: What is the maximum cable run for the balanced output?

A: The high-gain balanced line output supports cable runs up to 400 feet, making it suitable for large commercial facilities with long wire runs between the wall plate and amplification equipment.
