Wall-Mounted Bi-Directional Mic/Line Dante Interface 2X2 - Black

Ideal Use Cases

The RDL DB-RN22 is designed for installed audio systems that need to place two analog microphone or line sources onto a Dante or AES67 network while returning two network audio channels to balanced analog outputs. Its wall-mounted format provides two female XLR inputs on the front panel and two balanced, detachable wiring-block outputs on the rear. This arrangement supports installations where input connections need to remain accessible while network and output wiring are positioned behind the unit.

Each input can be configured for microphone or line operation. Software-selectable gain and P48 phantom power make the interface suitable for supported microphones as well as line-level sources. The two analog outputs provide software-controlled attenuation for the received network channels.

Why Choose This Model

The DB-RN22 combines bidirectional 2 x 2 analog audio conversion, Dante or AES67 networking, and PoE power in one compact wall-mounted interface. It supports 24-bit audio and sample rates of 44.1, 48, 88.2, and 96 kHz, with 48 kHz as the default. A 100 Mbps RJ45 connection provides the network interface, accompanied by rear-panel Link and Speed indicators.

Input gain options accommodate different source levels. Microphone gain is selectable at 35, 42, or 59 dB, while line input gain can be set to unity or 12 dB. P48 phantom power is independently software-selectable for each input and conforms to IEC 61938: 2013.

Installation and Integration

The unit measures 1.80 inches wide, 4.11 inches high, and 2.09 inches deep. Its wall-mounted construction places both XLR input connectors and the Sync and Power indicators on the front panel. The balanced analog outputs, Ethernet connection, and Ethernet Link and Speed indicators are located on the rear.

Network audio operates through Dante or AES67 at a transmission rate of 100 Mbps. Power is supplied through PoE Class 0 in accordance with IEEE 802.3af. During configuration, gain and phantom power can be selected in software for each input. Each analog output also has software-controlled attenuation from 0 to -63 dB, plus an OFF setting, applied to its received network channel. The specified ambient operating range is 0° C to 50° C.

Performance Highlights

The DB-RN22 covers 20 Hz to 20 kHz with a stated frequency-response tolerance of ±0.5 dB. Its operating relationship is +4 dBu at -18 dBFS, while 0 dBFS corresponds to +22 dBu. Maximum balanced output level is +22 dBu, with more than 18 dB of headroom above the nominal +4 dBu operating level.

At 59 dB input gain, equivalent input noise is specified below -128 dBu and below -130 dBu A-weighted. Input THD+N is below 0.1% from 20 Hz to 20 kHz at +4 dBu/-18 dBFS. CMRR is greater than 65 dB from 50 to 120 Hz, and input-to-input crosstalk is specified below the noise floor at operating level with maximum microphone gain.

The balanced outputs have a 150-ohm impedance and total harmonic distortion below 0.01% at 1 kHz. Output noise is below -80 dB relative to +4 dBu and below -100 dB relative to +22 dBu. The two inputs have an impedance greater than 1.2 kilohms.

What Makes It Different

This model brings both analog-to-network and network-to-analog paths into the same wall-mounted unit. Two accessible front-panel XLR connectors accept mic or line signals, while two rear balanced outputs deliver received network audio. Software control extends beyond input selection: it covers three microphone gain settings, two line gain settings, P48 phantom power, and independent analog output attenuation.

Support for both Dante and AES67 provides two specified network-audio protocol options. Four supported sample rates, 24-bit conversion, PoE operation, and dedicated front and rear status indicators complete the interface’s defined integration feature set.

Final Assessment

The RDL DB-RN22 is a focused 2 x 2 interface for wall-mounted Dante or AES67 audio integration. It combines two configurable XLR mic/line inputs with two balanced analog outputs, software-selectable gain and phantom power, and software-controlled output level. Its 20 Hz to 20 kHz response, 24-bit audio support, selectable sample rates through 96 kHz, compact dimensions, and IEEE 802.3af PoE requirement provide a clearly specified foundation for bidirectional analog and network audio connections.
