Overview
The RU-BNF modules are Dante audio network interface products compatible with RDL Format-A twisted pair products. These modules are designed to be mounted in equipment racks, closets, conference tables and on shelves or backboards in commercial/industrial installations.
APPLICATION: The RU-BNF is an RDL Format-A sender/receiver that connects to a Dante-enabled network, providing all the features of an RDL RU-FN Format A to Network Interface and an RU-NFD Network to Format-A Interface/Distributor.
Network to Format-A Interface/Distributor Section
The RU-BNF converts three Dante audio channels to RDL Format-A. Each network channel corresponds to Pair A, B or C of the Format-A outputs. The unit converts a fourth Dante audio channel to a balanced line-level AUX output.
One front-panel green signal LED corresponds to each of the four Dante input channels. Received audio level is indicated on the variable-intensity LED indicator, facilitating setup when a networked computer is not connected at the module’s location.
The Format-A output is distributed to three separate rear-panel RJ45 jacks. Each Format-A output jack provides up to 200 mA of power to connected Format-A receivers. Multiple receivers may be daisy chained from one output jack, or may be connected by home run to each of the three outputs. Higher current Format-A receivers, such as RDL D-PSP1A powered Decora-style speakers, are to be individually connected to a separate output jack.
The RU-BNF output jacks support the entire range of Format-A receivers, making each output pair available for end-user connection on various wall plates, or feeding other equipment using rack-mounted, shelf-mounted or utility Format-A receivers. The wide array of Format-A receivers provide compatibility with commercial audio equipment operating at standard professional levels. High resolution digital audio converters coupled with RDL’s renowned analog filters provide superior fidelity with a very low noise floor. Each Format-A receiver may be connected near the RU-NFD or up to several thousand feet distant.
Format-A to Network Interface Section
The RU-BNF converts the three Format-A audio pairs to Dante networked digital audio channels. Each network channel corresponds to Pair A, B or C of the Format-A input. The unit converts a fourth input, balanced or unbalanced line-level AUX, to Dante.
One front-panel green signal LED corresponds to each of the three Format-A input channels. Received audio level is indicated on the variable-intensity LED indicator, facilitating setup when a networked computer is not connected at the module’s location. A Dual-LED VU meter facilitates adjustment of the front-panel AUX input gain control. The AUX input supports the complete range of normal unbalanced and balanced line-level sources.
The Format-A input jack provides up to 200 mA of power to connected Format-A senders. Multiple senders may be daisy chained from the Format-A input jack.
The RU- BNF Format-A input supports the entire range of Format-A senders, making each input pair available for end-user connection on various wall plates, or receiving signals from other equipment using rack-mounted, shelf-mounted or utility Format-A senders. The wide array of Format-A senders provides compatibility with commercial audio equipment operating at standard professional levels. High resolution digital audio converters coupled with RDL’s renowned analog filters provide superior fidelity with a very low noise floor. Each Format-A sender may be connected near the RU- BNF or up to several thousand feet distant.
The RU-BNF is powered from an external 24 Vdc power supply, available separately. The external supply powers the RU-BNF, Format-A senders connected to the Format-A input jack and Format-A receivers connected to all three Format-A outputs. The RU-BNFP is equipped for PoE which powers the RU-BNF, Format-A senders connected to the Format-A input, and Format-A receivers connected to the primary Format-A output jack. Audio is also distributed to the other two output jacks. Remote Format-A receivers connected to those other two output jacks are only powered from the RU-BNFP if an external 24 Vdc power supply is connected. If PoE power and an external 24 Vdc supply are both feeding an RU-BNFP, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external 24 V supply. The power feeding each Format-A RJ45 connector is separately protected by an automatically resetting fuse. A power LED is associated with each connector, facilitating identification of wiring faults.
PoE relies on the use of a PoE enabled network switch. The RU-BNF will reserve power from the switch even while being powered from an external 24 Vdc supply.
The RU-BNF is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. Built to last. Built to outperform.
