The D SERIES-BTN44 modules are Dante networked, wall-mounted audio interfaces that include bidirectional Bluetooth audio, unbalanced analog stereo or mono audio inputs and outputs, and a balanced or unbalanced line-level output. Stereo audio from a compatible Bluetooth-enabled device feeds two Dante network audio channels. Stereo audio connected to a front-panel Mini-Jack or L and R RCA jacks feeds two other Dante network audio channels.

Stereo audio is available to users through a front-panel Mini-Jack fed from two Dante network channels. A rear-panel terminal block provides either a balanced (+4 dBu) or unbalanced (-10 dBV) output from one Dante network channel. That output may feed a variety of RDL wall panels to provide a specific mic or line level output to users, or it may be used to feed the audio power amplifier in the associated audio zone. One Dante channel may be routed back to a connected device through the Bluetooth interface enabling full duplex communication.

The D SERIES-BTN44 modules are powered from PoE. The installer can customize the module name and programming password through the Bluetooth connection using a smartphone, computer or tablet terminal program. These modules feature studio-quality circuits and analog filters to provide audio performance exceeding expectations from consumer interface technologies. High performance, simplicity of operation and efficiency of installation make RDL the best value in professional Bluetooth interfaces.

D-SERIES

D Series products are user controls, indicators and connection plates that are compatible with Decora® style mounting. D Series modules and jacks connect directly to a variety of active RDL modules in multiple product series and are compatible with many OEM products. Products in this series may be active or passive. All D Series front panels are constructed of stainless or carbon steel for durability, shielding and static protection. Stainless steel models feature a brushed finish with direct lettering. Painted models are finished with a reverse-printed front-panel polycarbonate laminate which provides an attractive, durable finished appearance.

Connector plates offer pass-thru jacks or rear-panel solder terminals. Transformer-isolated connector modules are equipped with a shielded enclosure and a rear-panel terminal block.

Active models include remote controls to provide source selection, routing, level control, muting, source or level LED indication and more.

The depth of D Series products is sufficiently shallow to permit mounting not only in standard North American electrical boxes but also in RDL wall boxes designed to fit in narrow walls used in international installations. RDL also offers a variety of related accessories for wall mounting, surface mounting and desktop chassis mounting of D Series products, as well as matching metal trim plates.

Attractive styling, ease of installation, long-life pushbuttons, high quality connectors and worldwide mounting possibilities make D Series products a preferred long-term resource for system design solutions. D-SERIES modules are designed and manufactured in the U.S.A.
