Wall-Mounted Bluetooth Dante Interface- White

Ideal Use Cases

The RDL D-BTN21 is designed for installations that require a fixed, wall-mounted connection between Bluetooth audio and a Dante or AES67 network. It provides bidirectional Bluetooth audio, supporting applications in which audio must move between a Bluetooth-enabled source and a networked audio system. Stereo and summed mono audio are supported, giving the interface a defined role in systems using either format. The white finish is suitable for installations specified with a white wall-mounted interface.

Why Choose This Model

The D-BTN21 combines Bluetooth audio connectivity and standards-based network audio within a compact wall-mounted device. It supports both Dante and AES67 digital audio protocols, allowing it to operate within compatible networked audio environments. The RJ45 network connector supports a 100 Mbps transmission rate and includes Link and Speed indicators for checking the Ethernet connection.

Audio is handled at a 48 kHz sample rate with 24-bit depth. The specified nominal operating references are 20 dBFS = +4 dBu for balanced audio and -20 dBFS = -10 dBV for unbalanced audio. These published levels provide system designers and installers with concrete information for coordinating the interface with the rest of an audio system.

Installation and Integration

The wall-mounted format places Bluetooth access at a fixed location while connecting the interface to the audio network through RJ45. Power is supplied by PoE through the RJ45 connection, eliminating the need for a separately specified power connection. The D-BTN21 uses Class 0 PoE and conforms to IEEE 802.3af.

Front-panel Bluetooth and Network Sync indicators provide visible status information at the installed location. Link and Speed indicators are also provided at the network connector. The unit measures 1.71 inches wide by 4.11 inches high by 2.09 inches deep, or 4.34 by 10.44 by 5.31 centimeters. Its specified ambient operating range is 0 degrees C to 40 degrees C.

Supporting documentation identified in the source data includes a PDF datasheet and brochure. Engineering resources include an American DXF functional block file and American DXF front and rear panel diagrams. These materials can support planning, documentation, and installation work using the published product information.

Performance Highlights

The central performance capability is bidirectional Bluetooth audio over a Dante or AES67 network. This allows the interface to accommodate audio traveling in either direction between its Bluetooth function and the networked audio system. Audio can be carried in stereo or as summed mono, while the fixed 48 kHz, 24-bit specification defines the supported digital audio format.

The 100 Mbps network connection provides the specified Ethernet transmission rate. Network Sync status is visible from the front panel, while the RJ45 Link and Speed indicators help confirm network activity and connection speed. PoE supplies operating power through the network connection using the stated IEEE 802.3af Class 0 implementation.

What Makes It Different

The D-BTN21 brings together a wall-mounted form factor, bidirectional Bluetooth audio, Dante or AES67 compatibility, and PoE operation in one interface. Rather than being described only as a Bluetooth input, it is specifically identified as bidirectional. Its support for both stereo and summed mono audio further defines how it can participate in a networked audio design.

The combination of a white wall-mounted enclosure, compact dimensions, front-panel Bluetooth and Network Sync indicators, and Ethernet Link and Speed indicators makes the product’s operating state accessible at both the room-facing panel and network connection. Published operating levels, environmental limits, network speed, sample rate, and bit depth provide concrete parameters for integration.

Final Assessment

The RDL D-BTN21 is a focused network audio interface for systems requiring wall-mounted, bidirectional Bluetooth connectivity. Dante and AES67 protocol support, 48 kHz/24-bit audio, stereo or summed mono operation, 100 Mbps Ethernet, and IEEE 802.3af Class 0 PoE define its core capabilities. Its compact white format and visible status indicators complete a clearly specified interface for compatible Bluetooth and networked audio installations.
