Wall-Mounted Bi-Directional Mic/Line Dante Interface 1×2

The RDL DB-RN12 is a wall-mounted, bi-directional Dante or AES67 audio network interface for converting mic- or line-level analog audio to network audio and returning network audio to balanced analog outputs. It provides one female XLR mic/line input, one balanced mic/line output through a front-panel XLR jack, and two balanced line outputs on the rear. Its compact format, software-selectable input settings, and PoE operation support streamlined integration into fixed networked-audio systems.

Ideal Use Cases

This model is suited to installations that need a wall-mounted analog connection point linked to a Dante or AES67 network. The local XLR input can accept a microphone or line-level source, while the analog outputs provide access to audio received from the network. Its combination of front- and rear-panel connections supports applications where an accessible XLR output is needed alongside permanently wired balanced outputs.

• Connecting a local microphone or line-level source to a Dante audio network
• Receiving network audio for balanced analog equipment
• Providing front-panel XLR access with rear-panel detachable wiring-block connections
• Adding bi-directional analog audio connectivity where wall mounting is required

Why Choose This Model

The DB-RN12 combines configurable mic/line input gain, P48 phantom power, balanced analog outputs, and network transport in a compact wall-mounted interface. Microphone gain is software-selectable at 35, 42, or 59 dB, while line input gain can be set to unity or 12 dB. P48 phantom power is also software-selectable and follows IEC 61938: 2013. These controls allow the input to accommodate different source levels without relying on fixed analog settings.

Each received network channel includes software-controlled analog output attenuation from 0 to -63 dB, plus OFF. This provides level adjustment before the received signal reaches connected analog equipment.

Installation and Integration

Network connectivity is provided through an RJ45 connector with rear-panel Link and Speed indicators. The interface operates at a 100 Mbps transmission rate and is powered using PoE Class 0 under IEEE 802.3af. Front-panel Sync and Power indicators provide visible operating-status information.

The unit measures 1.80 inches wide by 4.11 inches high by 2.09 inches deep. Its input uses a female XLR connector. The specified outputs include balanced XLR and detachable wiring-block connectivity, together with an additional balanced detachable wiring-block output. The supported ambient operating range is 0° C to 50° C.

Performance Highlights

The DB-RN12 supports 24-bit audio at 44.1, 48, 88.2, and 96 kHz, with 48 kHz identified as the default sample rate. Its stated audio operating relationship is -18 dBFS at +4 dBu, with 0 dBFS corresponding to a +22 dBu reference level.

Both mic and line input modes provide a 20 Hz to 20 kHz frequency response within ±0.5 dB. Equivalent input noise is specified below -128 dBu at 59 dB gain and below -130 dBu A-weighted. Input THD+N is below 0.1% from 20 Hz to 20 kHz at +4 dBu/-18 dBFS, while CMRR is greater than 65 dB from 50 Hz to 120 Hz.

The balanced outputs operate at a nominal +4 dBu and support a maximum level of +22 dBu. Output impedance is 150 ohms balanced, output THD is below 0.01% at 1 kHz, and available headroom above +4 dBu exceeds 18 dB.

What Makes It Different

The defining feature is the combination of bi-directional network audio, software-managed analog input settings, and multiple balanced output connections in a wall-mounted enclosure. The front-panel XLR output offers direct access, while rear detachable wiring blocks support installed cabling. Selectable phantom power, five mic/line gain choices, and per-channel output attenuation make the interface adaptable without changing its physical configuration.

Final Assessment

The RDL DB-RN12 is a focused interface for bringing one analog mic/line source onto a Dante or AES67 network while converting received network channels back to balanced analog audio. With 24-bit operation up to 96 kHz, software-selectable gain and P48 phantom power, balanced +22 dBu maximum outputs, PoE power, and a compact wall-mounted format, it provides a clearly specified connection point for networked-audio integration.
