RDL DD-BTN44 Bi-Directional Line-Level and Bluetooth Audio Dante Interface

The RDL D SERIES-BTN44 modules (DD-BTN44) 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.
