The AtlasIED WTSD-BT provides remote Bluetooth audio input to any audio system with a balanced line input. The WTSD-BT audio wall plate requires a PWBOB analog interface box and external power supply to operate (both included). The WTSD-BT can be installed up to 330' (100m) from the amplifier, providing flexible placement options. The WTSD-BT uses commercial-grade Bluetooth 5.1 technology featuring ultra-low noise performance, long-range connectivity, no auto-reconnect behavior, and a quick disconnect bump feature. The Bluetooth discovery ID name can be customized using the DMA Control iOS / Android app, allowing the broadcast to be tailored to the venue. 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" (38mm) of clearance depth. The AtlasIED WTSD proprietary low-voltage bus is designed to support a single wall plate or multiple WTSD devices. Up to (3) WTSD devices can be daisy-chained on the same bus, with audio from each device summed together while maintaining independent control. The WTSD-BT includes an onboard signal limiter to manage the level placed on the summed bus, with adjustable settings from -3 dB to 21 dB. The DMA-BT faceplate provides signal and limiter status indicators.
