DANTE AUDIO INTERFACES Output


RN02 Output, 2x 3-pin XLR, mic/line

RN02 is a wall-mounted Dante or AES67 audio network interface. It features two balanced XLR mic or line outputs on the front panel and on a rear-panel detachable wiring block. The module is configured and adjusted using RDL CONSOLE or other network control software. Two Dante or AES67 audio channels are converted to balanced line level feeding front-panel XLR jacks and a rear-panel detachable wiring block. Each output provides balanced +4dBu for a network digital audio level of -18dBFS. Each front-panel output is equipped with a software-controlled mic/line output attenuator pad. When an output is set to mic level, the step attenuator reduces the mic output in 1dB steps to a maximum attenuation of 63dB below mic level, then OFF.

Valid PoE power and synchronisation to the Dante network are indicated by green LEDs visible from the front of the unit. RN02 fits a standard US single-gang electrical box or can be used with the RDL EP-1 adaptor for mounting in EU/UK square back boxes with 60 mm distance screw hole mounting centres. Weight: 195g

The level of each output channel may be adjusted separately or together. If two or more user adjustment controls are desired in the same zone, an RDL NMC1R may be used to remote control NVC2, allowing adjustment by either unit. Network bandwidth typically supports up to 4x remote controls per zone. Weight: 168g
