The AtlasIED WTSD-BT is a commercial-grade Bluetooth 5.1 wall plate receiver designed to provide secure, remote wireless audio input to any sound system with a balanced line input. As part of the AtlasIED WTSD active wall plate series, the WTSD-BT delivers long-range performance, low-noise audio quality, and professional connection management for hospitality, education, retail, and multi-use commercial facilities.
Unlike consumer Bluetooth adapters, the WTSD-BT is purpose-built for installed audio systems, offering extended mounting distance, signal control, and daisy-chain expandability through the AtlasIED WTSD low-voltage bus architecture.
Universal Bluetooth Integration for Balanced Audio Systems
The WTSD-BT functions as a universal Bluetooth receiver and connects to systems with a balanced line input using the included:
This makes it compatible with a wide range of commercial amplifiers, mixers, and DSP-based audio systems.
The wall plate can be mounted up to 330 ft (100 meters) from the connected equipment using standard Cat5/6 cabling, allowing Bluetooth access exactly where users need it — without relocating rack equipment.
Commercial-Grade Bluetooth 5.1 Performance
Engineered for professional environments, the WTSD-BT features:
-
Bluetooth 5.1 technology
-
Ultra-low noise audio performance
-
Long-range connectivity
-
No automatic reconnect to last paired device
-
Push-button “bump” disconnect function
The no-auto-reconnect behavior prevents unwanted device takeovers in public environments such as gyms, ballrooms, or classrooms.
The Bluetooth discovery ID can be customized using the DMA Control iOS/Android app, allowing the broadcast name to reflect the venue (e.g., “Ballroom A Audio” or “Gym Sound System”).
WTSD Low-Voltage Bus Architecture
The proprietary AtlasIED WTSD low-voltage bus allows flexible system expansion:
-
Supports single or multiple WTSD wall plates
-
Up to three WTSD devices daisy-chained
-
Audio from each device is summed together
-
Independent control maintained per device
This makes the WTSD-BT ideal for facilities requiring multiple Bluetooth or input locations throughout a building.
Integrated Output Limiter & Status Indicators
To maintain system integrity, the WTSD-BT includes an onboard adjustable output limiter:
-
Adjustable from –3 dB to +21 dB
-
Prevents clipping and distortion
-
Protects the summed bus signal
Front-panel LED indicators provide clear signal and limiter status monitoring, simplifying troubleshooting and setup.
Installer-Friendly, Code-Compliant Design
The WTSD-BT is built for straightforward installation in commercial environments:
-
Fits standard 1-gang electrical boxes
-
Compatible with low-voltage rings
-
Requires only 1.5 inches (38 mm) mounting depth
-
Surface-mount design
-
Meets low-voltage electrical code requirements
-
Uses standard Cat5/6 cable
Its slim profile makes it suitable for both new construction and retrofit applications.
