Network to Mic/Line Interface-Dante Input-2 Balanced Mic/Line Outputs

The RDL FP-NML2 connects standard audio amplifiers to a Dante network by converting two Dante digital audio signals into two balanced analog outputs. Each output is switch-selectable for microphone or line level, allowing the interface to accommodate different downstream input requirements. High-resolution 24-bit digital-to-analog conversion, RDL analog filtering, and automatic output muting support clean, controlled audio integration.

Ideal Use Cases

The FP-NML2 is designed for systems that need to deliver Dante network audio to conventional amplifiers or other equipment with analog microphone- or line-level inputs. Its two balanced outputs make it suitable when two Dante signals must be converted to professional analog audio within a compact installation.

Selectable microphone and line output levels provide flexibility when integrating equipment with different input sensitivities. At line level, the interface supplies a nominal +4 dBu output with more than 18 dB of headroom. This makes the FP-NML2 particularly useful when existing analog amplification must be incorporated into a Dante-based signal path.

Why Choose This Model

The FP-NML2 combines Dante connectivity with two professional balanced analog outputs. Audio is transported through a 100 Mbps RJ45 network connection and converted at 24-bit resolution. Supported sample rates are 44.1 kHz and 48 kHz, with 48 kHz identified as the default.

Each output can be switched between microphone and line level, avoiding the need for a separate fixed-output interface for each application. The balanced outputs use a detachable terminal block for secure installation wiring. Ethernet Link, Ethernet Speed, and SYNC indicators provide visible operating-status information.

Installation and Integration

The network connection is provided through an RJ45 connector with Link and Speed indicators. Two balanced analog outputs are presented on a detachable terminal block. The enclosure measures 4.85 inches wide, 1.75 inches high, and 3.25 inches deep, or 12.3 by 4.45 by 8.26 centimeters.

The FP-NML2 can be rack mounted or surface mounted. It requires 24 Vdc at 100 mA and includes both a power jack and a 24 Vdc pass-through connection. The pass-through jack allows the power supply to be shared with RDL amplifiers. Recommended power supplies listed in the source data are the PS-24AS for the USA and the PS-24AX for international use.

The specified ambient operating range is 0 degrees C to 40 degrees C. The combination of compact dimensions, detachable output wiring, visible network indicators, and two mounting approaches supports straightforward integration into permanent audio installations.

Performance Highlights

The FP-NML2 delivers a nominal +4 dBu line-level output, with the audio operating reference specified as 18 dBFS equals +4 dBu. Headroom above +4 dBu is greater than 18 dB. Frequency response extends from 20 Hz to 20 kHz within ±0.5 dB, while THD+N is specified at less than 0.1 percent.

Noise below +4 dBu is specified at less than -80 dB while an output is active and less than -95 dB while the outputs are muted. Crosstalk is listed at less than 90 dB at 1 kHz and less than 80 dB from 20 Hz to 20 kHz. Output impedance is 150 ohms balanced or 75 ohms unbalanced.

When the digital audio inputs become inactive, the analog outputs mute automatically. This behavior helps control inactive output channels without requiring a separate external muting device.

What Makes It Different

The FP-NML2 is more than a basic network-to-analog converter. Its two outputs can each be selected for microphone or line operation, while line mode provides professional +4 dBu nominal output and substantial headroom. The design also pairs 24-bit conversion with RDL analog filtering for the stated low-noise and low-distortion performance.

The 24 Vdc pass-through connection further distinguishes this model in installations using compatible RDL amplifiers. It provides a practical way to share a power supply while retaining separate Dante conversion and amplifier functions.

Final Assessment

For a system requiring two Dante audio signals to feed balanced analog microphone- or line-level inputs, the RDL FP-NML2 offers a focused integration solution. Its 24-bit conversion, selectable output levels, +4 dBu line operation, greater than 18 dB headroom, automatic muting, status indicators, and rack- or surface-mounting capability directly address professional network-to-analog audio requirements.
