RDL AV INTERFACES - RACK-UP Series

RDL Rack-Up series are 1/3 rack-width, rack-mounting modules, 1U high, offered with a wide range of functionality. Some Rack-Up modules are constructed in solid, encapsulated, durable, industrial, black plastic enclosures; Max Rack-Ups are assembled using heavy-duty, extruded-aluminium and steel panels. The rear panels have 'clear bold white lettering' for the terminal blocks and connectors. Reverse-printed, front-panel, poly-carbonate laminates provide a durable finished appearance for rack-mounted or free-standing use. Certain Rack-Up modules are often used free-standing; all Rack-Ups may be rack mounted by means of a range of mounting options, listed within this group.

DANTE INTERFACES - Format-A - Bi-directional

Compatible with RDL Format-A twisted-pair products, these models are both RDL Format-A receivers and RDL Format-A senders that interface with a DANTE-enabled network. A Format-A RJ45 input has three audio channels which are converted to Dante networked digital audio channels. A fourth, balanced or unbalanced, line-level, auxiliary input is also converted to Dante. Three of the DANTE audio channels are converted to RDL Format-A outputs. A fourth DANTE channel is converted to a balanced, line-level, auxiliary output. They are offered with or without a POE (power over Ethernet) facility.

The modules provide all the features of an RDL RU-FN(P) Format A to Network Interface and an RU-NFD(P) Network to Format-A interface.

The Radio Design Labs Format-A system uses standard IT, networking cables to send receive and distribute audio signals. As a result, systems may be installed in existing buildings using the existing 'flood' wiring, thus avoiding the cost, damage and consequent making good of installing fresh cable. For further information, see RDL FORMAT-A SYSTEM

Format-A to Network:

The front-panel has a 'signal' LED corresponding to each of the three Format-A input channels. Received audio level is indicated on these variable-intensity LED indicators, facilitating setup when a networked computer is not connected at the location of the module. A dual-LED VU meter helps with adjustment of the AUX input gain control, again on the front-panel. This auxiliary input 'supports the complete range of normal unbalanced and balanced line-level sources.'

On the rear, the Format-A input connector provides up to 200mA of power to connected Format-A senders. Multiple senders may be loop-connected; they may be connected near the receiver or 'up to several thousand feet distant'. The power feeding the Format-A RJ45 connector is separately protected by an automatically resetting fuse. A power LED is associated with the connector, facilitating identification of wiring faults. A further RJ45 connector provides the single Ethernet connection used to send and receive; the auxiliary input is a detachable terminal block. Power is connected using another detachable block and a coaxial inlet.

Network to Format-A

The front-panel has a 'signal' LED corresponding to each of the four DANTE input channels. Received audio level is indicated on these variable-intensity LED indicators, facilitating setup when a networked computer is not connected at the location of the module.

On the rear, the three Format-A outputs are distributed to three separate RJ45 connectors; each output connector provides up to 200mA of power to connected Format-A receivers. Multiple senders may be loop-connected; they may be connected near the receiver or 'up to several thousand feet distant', but some higher-current Format-A receivers should be connected individually to a separate output socket. The power feeding each of the Format-A RJ45 connectors is separately protected by an automatically resetting fuse. A power LED is associated with each connector, facilitating identification of wiring faults. The auxiliary output is a detachable terminal block.

Optional accessories: Mounting accessories offer a variety of mounting panels, trays, brackets and adapters. 57-402, an 'RDL PS-24AX POWER SUPPLY Universal, 24 volt, 500mA, UK plug' is a suitable power supply.

These two models differ principally in terms of the powering arrangements:


RU-BNF

The RU-BNF is powered from an external 24V DC 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.


RU-BNFP

The RU-BNFP is equipped for POE which powers the RU-BNFP, the Format-A senders connected to the Format-A input, and the Format-A receivers connected to the primary Format-A output connector. Audio is also distributed to the other two output connectors. Remote Format-A receivers connected to these other two output connectors are only powered from the RU-BNFP if an external 24V DC power supply is connected. If both POE power and an external 24V DC supply are 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 24V supply. POE relies on the use of a POE-enabled network switch. The RU-BNFP will reserve power from the switch even while being powered from an external 24V DC supply.

Powering

Powering: All units require a 24V DC power supply; each has both screw terminals and coaxial socket for power input. A ‘universal’ supply is available, 57-401, with 24V 3A output, which requires an IEC cord set. See RDL POWER SUPPLIES for more details. Note that all RDL modules with co-axial power input/output sockets use connectors with 2.5mm pins.
