The AtlasIED WTSD-ML provides remote mic/line audio input to any audio system with a balanced line input. The WTSD-ML audio wall plate requires a PWBOB analog interface box and external power supply to operate (both included). The WTSD-ML can be installed up to 330 ft (100 meters) from the amplifier, providing flexible placement options. The WTSD-ML uses commercial grade microphone preamps featuring ultra-low noise performance, high-gain output, mic or line level selection, phantom power, 20 dB pad, 120 Hz high pass filter and rotary detented level control. Installation meets low voltage standards and is straightforward, with the wall plate fitting into a standard single gang electrical box or low voltage ring and requiring only 1.5 inches (38 mm) of clearance depth.

The AtlasIED WTSD proprietary low-voltage bus is designed to support a single wall plate or multiple WTSD devices. Up to three WTSD devices can be daisy-chained on the same bus, with audio from each device summed together while maintaining independent control. The WTSD-ML includes an onboard signal limiter to manage the level placed on the summed bus, with adjustable settings from −3 dB to 21 dB. The WTSD faceplate provides signal and limiter status indicators.
