RDL RU-BNFP Format-A Bi-Directional Network Interface, PoE
The RU-BNF modules are Dante audio network interfaceproducts compatible with RDL Format-A twisted pair products. These modules aredesigned to be mounted in equipment racks, closets, conference tables and onshelves or backboards in commercial/industrial installations.
APPLICATION
The RU-BNF is an RDL Format-A sender/receiver that connectsto a Dante-enabled network, providing all the features of an RDL RU-FN Format Ato 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 RDLFormat-A. Each network channel corresponds to Pair A, B or C of the Format-Aoutputs. The unit converts a fourth Dante audio channel to a balancedline-level AUX output.
One front-panel green signal LED corresponds to each of thefour Dante input channels. Received audio level is indicated on thevariable-intensity LED indicator, facilitating setup when a networked computeris not connected at the module’s location.
The Format-A output is distributed to three separaterear-panel RJ45 jacks. Each Format-A output jack provides up to 200 mA of powerto connected Format-A receivers. Multiple receivers may be daisy chained fromone 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-stylespeakers, are to be individually connected to a separate output jack.
The RU-BNF output jacks support the entire range of Format-Areceivers, making each output pair available for end-user connection on variouswall plates, or feeding other equipment using rack-mounted, shelf-mounted orutility Format-A receivers. The wide array of Format-A receivers providecompatibility with commercial audio equipment operating at standardprofessional levels. High resolution digital audio converters coupled withRDL’s renowned analog filters provide superior fidelity with a very low noisefloor. Each Format-A receiver may be connected near the RU-NFD or up to severalthousand feet distant.
The RU-BNF converts the three Format-A audio pairs to Dantenetworked digital audio channels. Each network channel corresponds to Pair A, Bor C of the Format-A input. The unit converts a fourth input, balanced orunbalanced line-level AUX, to Dante.
One front-panel green signal LED corresponds to each of thethree Format-A input channels. Received audio level is indicated on thevariable-intensity LED indicator, facilitating setup when a networked computeris not connected at the module’s location. A Dual-LED VU meter facilitatesadjustment of the front-panel AUX input gain control. The AUX input supportsthe complete range of normal unbalanced and balanced line-level sources.
