DDB-BN22

RDL DDB-BN22 - wall-mounted bidirectional Dante 2x2 interface with XLR microphone/line inputs and outputs, PoE power, black

The RDL DDB-BN22 is a wall-mounted Dante network interface that operates in both directions: sending audio to the network and receiving it from it. It has two XLR microphone/line inputs that convert signals from microphones or line sources into two Dante transmission channels. It also features two XLR outputs that receive two Dante channels and provide them at microphone or line level. This allows microphones to be connected at a single wall point and the signal to be routed, for example, to a recorder, camera, or sound system. The interface is powered via PoE and fits into a standard double electrical box or an RDL WB-2U box. No special software is needed for configuration, as each input has microphone/line mode switches, 48V phantom power, and gain controls, while each output has a microphone/line level switch. Discrete microphone preamps, 24-bit A/C and C/A processing, and RDL analog filtering ensure clean, low-noise audio. Metal XLR connectors, a stainless steel housing, and black Decora faceplates guarantee durability and an aesthetic appearance.
