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 - Output

These RDL Format-A 'sender/distributors' provide an interface between a DANTE audio network and RDL Format-A twisted-pair products. Three of the DANTE audio channels to 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.

DANTE is a software and hardware solution, offering high-performance audio distribution over standard IP networks, supporting hundreds of simultaneous channels of uncompressed audio with low latency and accurate synchronisation.

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.

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. A further RJ45 connector provides an Ethernet connection; the auxiliary input is a detachable terminal block. Power is connected using another detachable block and a coaxial inlet.

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-NFD

The RU-NFD is powered from an external 24V DC power supply, available separately. The external supply powers the RU-NFD and Format-A receivers connected to the Format-A outputs.


RU-NFDP

The RU-NFDP is equipped for POE which powers the RU-NFD and the Format-A receivers connected to the primary Format-A output socket. Audio is also distributed to the other two output sockets. Remote Format-A receivers connected to those other two output jacks are only powered from the RU-NFDP if an external 24V DC power supply is connected. If POE power and an external 24V DC supply are both feeding an RU-NFDP, 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-NFDP 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.
