AtlasIED WTSD-MIX31K Indoor/Outdoor 3x1 Analog Wall Mixer

The AtlasIED WTSD-MIX31K is engineered for systems integrators and commercial AV installers who need a compact, multi-source mixing point at the zone level. Designed for indoor and outdoor deployment, it consolidates a balanced XLR mic/line input, a stereo 3.5mm AUX input, and a commercial-grade Bluetooth input into a single balanced bus output — all within a 2-gang wall footprint using standard Cat5/Cat6 infrastructure. Phantom power, a 125Hz low-cut filter, and a local mute button make it equally capable as a paging station or background music source selector in hospitality, corporate, house of worship, and retail environments.

Unlike consumer-grade wall plates, the WTSD-MIX31K uses commercial Bluetooth with no auto-connect behavior and a quick-disconnect bump feature, giving facility managers predictable control in multi-user environments. The customizable Bluetooth Discovery ID and adjustable VOX ducking allow installers to tailor the unit to the deployment without additional DSP hardware. A system priority mute button can silence building-wide BGM, making it practical for emergency paging scenarios.

The included WTSD-PWBOB interface board provides balanced audio output with signal, mute, system priority, and power LED indicators, plus 12V DC logic output for remote amplifier sequencing. For facilities planning a migration to networked audio, the optional TSD-DAC2i converts the analog output to Dante, protecting the infrastructure investment without requiring panel replacement. The WTSD-MIX31K links with other WTSD-series mixers on the same bus, supporting scalable distributed audio designs across multiple zones.
