RDL Wall-Mounted Bi-Directional Mic/Line Dante Interface 2 x 2 - DD-BN22

Product Overview

The RDL DD-BN22 is a wall-mounted, bi-directional Dante audio interface designed for permanent installation in commercial AV environments where analog mic and line sources need to connect to a Dante audio network. Supporting two channels of Dante transmit and two channels of Dante receive, this XLR wall plate Dante network audio device enables integrators to bring balanced analog signals onto a Dante network—and return Dante audio back to analog outputs—from a single, Decora-style wall plate. The DD-BN22 is PoE powered, requires no special configuration software, and fits a standard dual-gang electrical box, making it a straightforward choice for conference room audio infrastructure, boardroom installs, and distributed AV systems where clean, network-based audio routing is required.

Product Description

The RDL DD-BN22 bi-directional Dante wall plate provides two XLR mic/line inputs and two XLR mic/line outputs on its front panels, translating analog signals to and from a Dante audio network with 24-bit A/D and D/A conversion. Discrete mic preamps handle the input signal chain, with switch-selectable mic gain settings of 40 dB, 48 dB, or 62 dB to accommodate a wide range of microphone types and placement distances. For line-level sources, gain can be set to unity, +12 dB, or +19 dB. Per-input switches for P48 phantom power enable or disable, gain range selection, and gain level are accessible from the front panel when the cover plate is removed—no laptop, no software, no network configuration required for basic setup.

On the output side, each channel can be switch-configured for balanced professional line level (+4 dBu) or mic level with –50 dB attenuation, giving system designers flexibility when feeding downstream devices such as DSPs, amplifiers, or recording interfaces. The unit is powered entirely over PoE, eliminating the need for a local power supply or additional wiring beyond a single Cat cable run to a PoE-capable network switch. Front-panel green LEDs confirm valid PoE power and active Dante network synchronization, providing at-a-glance status during commissioning or troubleshooting.

Physically, the DD-BN22 mounts in a standard US dual-gang electrical box. For installations in thinner walls or European-equivalent construction, RDL's WB-2 back box is supported. The stainless steel chassis is paired with dual powder-coated or stainless steel Decora front plates, with multiple finish options available and optional customized graphics for professional-grade labeling. Engineered and manufactured in the USA, the DD-BN22 is appropriate for permanent commercial AV installations where reliability, signal quality, and clean network integration are priorities.

Key Features

• Bi-Directional 2x2 Dante Interface — Two channels of Dante transmit (analog in to network) and two channels of Dante receive (network to analog out) in a single wall plate.
• XLR Mic/Line Inputs with Discrete Preamps — Balanced XLR inputs with discrete mic preamps and 24-bit A/D conversion deliver clean, low-noise signal capture from microphones or line-level sources.
• Switch-Selectable Mic Gain — Per-input gain settings of 40 dB, 48 dB, or 62 dB accommodate dynamic and condenser microphones across varied room sizes and mounting positions.
• Switch-Selectable Line Gain — Unity, +12 dB, or +19 dB line gain options support direct connection of program sources, presentation audio, and other line-level equipment.
• P48 Phantom Power Per Input — Independent phantom power enable/disable switch on each input channel allows mixed microphone types on the same device without signal compromise.
• Professional and Mic Level Output Selection — Each output channel can be set to balanced +4 dBu professional line level or mic level (–50 dB attenuation) to match downstream device requirements.
• PoE Powered — Single Cat cable delivers both network connectivity and DC power via PoE; no local power supply or additional cabling required.
• No Configuration Software Required — Basic operation and gain staging are set via front-panel DIP switches accessible behind the cover plate, reducing commissioning time on the jobsite.
• Status LEDs — Green LEDs confirm valid PoE power and Dante network synchronization at a glance during installation and ongoing operation.
• Dual-Gang Electrical Box Mount — Fits standard US dual-gang boxes; compatible with RDL WB-2 back box for thinner or non-standard wall construction.
• Multiple Finish Options with Custom Graphics — Powder-coated or stainless steel Decora front plates with optional custom labeling for professional, permanent AV installations.
• USA Engineered and Manufactured — Built to commercial AV quality standards with stainless steel chassis construction.

Technical Specifications

Frequently Asked Questions

Q: Is the DD-BN22 compatible with all Dante-enabled devices and DSPs?
A: Yes. The DD-BN22 is a standard Dante device and is compatible with any Dante-enabled platform—including DSPs, mixers, amplifiers, and recording systems from manufacturers such as Biamp, QSC, Shure, and others—using Audinate's standard Dante Controller software for network routing.

Q: Does the DD-BN22 require configuration software for basic operation?
A: No special software is required for basic configuration. Gain levels, gain range selection, phantom power, and output level are all set via DIP switches accessible from the front panel when the cover plate is removed. Dante channel routing is handled through Audinate's free Dante Controller software, which is standard practice across all Dante installations.

Q: What gang box does the DD-BN22 require?
A: The DD-BN22 mounts in a standard US dual-gang electrical box. For installations in thinner walls or non-standard construction, RDL offers the WB-2 back box as an optional accessory to provide proper depth and support.

Q: What PoE standard is required to power the DD-BN22?
A: The DD-BN22 is powered via PoE (Power over Ethernet). A PoE-capable network switch or PoE injector is required at the network infrastructure level. Consult RDL's published specifications or your RDL dealer for the exact PoE class requirement to confirm switch compatibility.

Q: Can phantom power be enabled on just one input while the other remains off?
A: Yes. Phantom power (P48) is switch-selectable independently per input channel, allowing one input to power a condenser microphone while the other input handles a dynamic mic or line-level source without interference.

Q: What finish options are available, and can the plates be customized?
A: The DD-BN22 is available in multiple finishes with dual powder-coated or stainless steel Decora front plates. Optional customized graphics are available for professional labeling, which is useful for permanent installations in boardrooms, government spaces, or any environment where clear source identification is required.

Q: Is the DD-BN22 suitable for capturing both microphone and line-level sources simultaneously?
A: Yes. Each input is independently configurable for either mic gain (40 dB, 48 dB, or 62 dB) or line gain (unity, +12 dB, or +19 dB), so one input can be set for a microphone while the second handles a line-level source such as a laptop audio output or program feed.

Q: Where is the DD-BN22 manufactured, and does it carry a warranty?
A: The DD-BN22 is engineered and manufactured in the USA. For warranty terms, contact Creation Networks or refer to RDL's official warranty documentation provided with the product.
