Description

The DDS-RN42 is a complete wall-mounted Dante audio network interface. It features two XLR mic or line inputs on the front panels, two balanced line inputs on a rear-panel detachable terminal block and two balanced line outputs on front-panel XLR jacks. The module is configured and adjusted using RDL CONSOLE or other network control software. The DDS-RN42 fits a standard US dual-gang electrical box or an RDL WB-2 back box for installations in thinner European or equivalent walls. The DDS-RN42 is PoE powered, and is available in multiple finishes with optional customized graphics.

Mic/Line to network section
The two XLR inputs are each converted to a separate Dante network transmit channel. Three gain settings are software-selectable for both the mic and line input ranges to match condenser or dynamic mic levels and standard line levels. P48 phantom voltage may be software enabled when an input is set for mic level.

Line to network section
The two rear-panel balanced or unbalanced inputs are each converted to a separate Dante network transmit channel. Control software sets the gain for an input level of either +4 dBu or -10 dBV. RDL Decora®-style jack plates matching the appearance of the DDS-RN42 are optionally available for connection of various audio sources to the rear-panel inputs. An input plate may be located together with the DDS-RN42 in a triple gang box or may be mounted remotely in a single box.

Network to line section
Two Dante audio channels are converted to balanced line level feeding front-panel XLR jacks. Each output provides +4 dBu balanced for a network digital audio level of -18 dBFS. Each output is equipped with a software controlled attenuator adjustable in 1 dB steps to a maximum attenuation of 62 dB then OFF. The outputs are connected through a detachable terminal block.

Valid PoE power and synchronization to the Dante network are indicated by green LEDs visible from the front of the unit.

The DDS-RN42 is a professional grade product with RDL mic preamplifiers for studio quality fidelity and low noise performance, coupled through XLR jacks housed in a steel chassis with dual powder-coated or stainless steel Decora front plates.

The DDS-RN42’s superior performance specifications make it ideally suited to installations requiring network control and exceptional value in commercial networked audio systems. This full-featured product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. Designed to outperform. Built to last.
