Network to Line Level Interface-Dante Input-2 Balanced Line Outputs

The RDL RU-NL2 is a two-channel network-to-line-level interface designed to convert two Dante network audio signals into professional analog outputs. Each of its two outputs is balanced and presented on a detachable terminal block, with a nominal +4 dBu output level and more than 18 dB of headroom. High-resolution 24-bit digital-to-analog conversion, RDL analog filtering, and automatic muting when digital inputs become inactive support clean, controlled integration with professional line-level equipment.

Ideal Use Cases

The RU-NL2 is suited wherever two Dante audio sources must feed analog equipment at professional line level. The two-output design supports installations that need a direct bridge between networked audio and balanced analog signal paths without adding unrelated functions. Its 5.8-inch-wide, 1.7-inch-high, and 5.2-inch-deep chassis can be rack mounted or surface mounted, allowing its placement to follow the installation. Separate audio and network indicators are useful when source activity and Dante synchronization need to be checked at the unit.

Why Choose This Model

Choose this model when the requirement is specifically to convert two Dante network audio signals into two balanced analog outputs. It supports 44.1 kHz and 48 kHz sample rates, with 48 kHz as the default, and uses 24-bit conversion. The stated audio operating relationship is 18 dBFS = +4 dBu, aligning the digital and analog sides around the unit’s professional nominal output level. Output impedance is 150 Ω balanced or 75 Ω unbalanced, while the detachable terminal block provides practical wiring access. The RU-NL2 also gives visible confirmation through power, audio-signal, network system, network sync, Ethernet link, and Ethernet speed indicators.

Installation and Integration

Network connection is through RJ45 at a 100 Mbps transmission rate. Power for the RU-NL2 is 24 Vdc at 105 mA, connected through either the power jack or detachable terminal block. The listed recommended supplies are the PS-24AS for the USA and PS-24AX for international use. PoE operation belongs to the related RU-NL2P model and should not be assumed for this RU-NL2. For placement, the enclosure is equipped for rack or surface mounting. Its specified ambient operating range is 0° C to 40° C. Once network audio is routed, the indicators allow power, audio presence, network system status, synchronization, link, and speed to be observed directly.

Performance Highlights

The RU-NL2 covers 20 Hz to 20 kHz with a stated ±0.5 dB frequency response. THD+N is specified below 0.05%. Noise relative to +4 dBu is below -80 dB while an output is active and below -95 dB when the outputs are muted. Crosstalk is specified at less than 85 dB from 20 Hz to 20 kHz, and the product information describes crosstalk as below the noise floor. With more than 18 dB of headroom above +4 dBu, the interface accommodates signal peaks beyond nominal operating level. If the digital audio inputs are inactive, the analog outputs mute. Audio signal LEDs indicate activity for the Dante sources, while system and sync indicators report network condition.

What Makes It Different

What distinguishes this unit is its focused combination of two-channel Dante reception, professional +4 dBu analog output, and RDL analog filtering in a mounting-ready enclosure. Its defined role is a precise two-channel transition from Dante network audio to line level. Balanced detachable-terminal-block outputs suit wired integration, while the status LEDs expose both audio activity and network state. The combination of 24-bit conversion, specified low-noise and low-distortion performance, automatic output muting, and more than 18 dB of headroom addresses conversion performance as well as day-to-day system visibility.

Final Assessment

For a system requiring two Dante signals to emerge as two balanced professional analog feeds, the RU-NL2 provides the relevant conversion, output level, monitoring, and mounting provisions in one interface. Its 44.1/48 kHz support, 24-bit depth, +4 dBu nominal outputs, 20 Hz to 20 kHz response, and clear network and signal indications make its capabilities straightforward to match against an installation specification. Select the RU-NL2 when 24 Vdc power is appropriate; the stated PoE option applies specifically to the separate RU-NL2P model.
