DDS-BN22

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

The RDL DDS-BN22 is a wall-mounted Dante interface featuring stainless steel front panels, which transmits audio from and to the Dante network at a single connection point. Two XLR inputs accept signals from microphones or line sources and send them to the network as two Dante transmit channels. Two XLR outputs provide two Dante receive channels at microphone or line level. This allows for connecting microphones and obtaining signals for cameras, recorders, broadcasts, or local sound reinforcement in one location on the wall. The module is powered via PoE and fits in a standard double electrical box or in the RDL WB-2 box designed for thinner walls. Configuration is done using switches on the module, without special software. For each input, the microphone/line mode, 48V phantom power, and gain are selected, and for each output, the microphone or line level is set. Discrete microphone preamps, 24-bit conversion, and RDL analog filtering ensure clean sound with low noise. The stainless steel housing and panels, along with metal XLR connectors, provide an elegant appearance and high durability for intensive use.
