Bi-Directional Mic/Line Dante Interface 2 x 2 w/PoE-2 XLR In, 2 Out on Rear-Panel Terminal Block-White

Ideal Use Cases

The RDL DD-BN2M is a complete wall-mounted, bi-directional 2 x 2 Dante audio network interface for systems requiring two local analog inputs and two local analog outputs at one wall location. Two front-panel female XLR connectors accept microphone- or line-level sources, while two balanced outputs are provided on a detachable rear-panel terminal block. This configuration suits fixed Dante installations that need accessible source connections and concealed output wiring.

Each input includes independent Phantom, Mic/Line, and Gain selectors. Switch-selectable P48 phantom power supports compatible microphones, while three mic gain settings and three line gain settings accommodate different source levels.

Why Choose This Model

The DD-BN2M combines analog input, analog output, Dante networking, and PoE operation in one compact wall-mounted interface. Audio is transmitted over a 100 Mbps Ethernet connection using the Dante protocol. The interface supports 24-bit audio at 44.1 kHz or 48 kHz, with 48 kHz as the default sample rate.

Its two outputs can operate as balanced +4 dBu nominal connections or switch-selectable unbalanced -10 dBV connections. Maximum output levels are +24 dBu balanced and +10 dBV unbalanced, providing 20 dB of headroom above the stated nominal output levels.

Installation and Integration

The interface measures 3.52 inches wide, 4.11 inches high, and 2.09 inches deep. It mounts in a North American dual electrical box, with a four-square deep box recommended, or in an RDL WB-2U international wall box. The specified mounting elevation is no more than 2 meters.

A rear RJ45 connector provides the network connection and includes Link and Speed indicators. Power is supplied through PoE Class 0 compliant with IEEE 802.3af, eliminating the need for a separately specified local power connection. Front-panel Sync and Power indicators provide operating-status visibility.

Performance Highlights

The DD-BN2M has a specified frequency response of 20 Hz to 20 kHz within ±0.5 dB. Microphone gain settings are 40 dB, 48 dB, and 62 dB. The primary gain specification lists line settings of unity, 8 dB, and 19 dB. Input impedance is greater than 2.5 kΩ in microphone mode and greater than 5 kΩ in line mode.

THD+N is specified below 0.1% from 20 Hz to 20 kHz at +4 dBu/-20 dBFS, with typical performance of 0.015% at 1 kHz. CMRR is greater than 65 dB from 50 Hz to 120 Hz, and input-to-input crosstalk is specified below the noise floor at operating level and maximum microphone gain.

The balanced outputs have a 150 Ω output impedance, while unbalanced operation has a 2.5 kΩ output impedance. Output THD is below 0.01% at 1 kHz. Output noise is specified below -80 dB relative to +4 dBu or -10 dBV and below -100 dB relative to +24 dBu.

What Makes It Different

The physical connection layout distinguishes this model: frequently accessed mic/line inputs remain on the front, while output and network wiring stay on the rear. Each input can be configured locally for phantom power, signal type, and gain. The combination of two XLR inputs, two detachable terminal-block outputs, Dante transport, and IEEE 802.3af PoE provides both input and output connectivity within a single wall-mounted unit.

Final Assessment

The RDL DD-BN2M is a purpose-built choice for a wall-mounted 2 x 2 Dante endpoint. Its 24-bit conversion, selectable mic or line operation, P48 phantom power, balanced or unbalanced output levels, compact dimensions, and PoE power requirement provide a clearly defined interface for integrating two analog sources and two analog outputs with a Dante audio network.
