RDL RACK-UP DANTE NETWORK INTERFACES - Format-A - Input

Compatible with RDL Format-A twisted-pair products, these models are RDL Format-A receivers that interface with a DANTE-enabled network. The 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. They are offered with or without a POE (power over Ethernet) facility.

The 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-aluminum and steel panels. The rear panels have 'clear bold white lettering' for the terminal blocks and connectors. Reverse-printed, front-panel, polycarbonate 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.

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 synchronization. For further information, see DANTE Networking Basics.

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

Optional accessories: See RDL Rack-Up Mounting Accessories for 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-FN

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

RU-FNP

The RU-FNP is equipped for POE, which powers the RU-FNP and the connected Format-A senders. If POE power and an external 24V DC supply are both feeding an RU-FNP, the unit will run from the external supply and will seamlessly switch over to POE power upon loss of the external supply. POE relies on the use of a POE enabled network switch. The RU-FNP will reserve power from the switch even while being powered from an external 24V DC supply.
