RDL PS-24AX-EU POWER SUPPLY Universal, 24 volt, 500mA, Euro plug

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.

These modules interface standard line-level audio signals with a DANTE audio network, providing 'flexibility, economy and simplicity' to DANTE networked audio systems. Built in RDL's 'Rack-Up' packaging, they will mount directly to surfaces or using a range of mounting options. Each provides line-level outputs from two or four DANTE network audio channels. They are offered with or without a POE (power over Ethernet) facility.

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.

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.

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.

RU-NMP44 4x4 Network Mixing Processor

Designed for adding volume control, mixing, switching and ducking to existing network audio systems within classrooms, meeting rooms, restaurants/bars, fitness gyms and retail stores, RU-NMP44 is a network mixing processor containing six virtual audio mixers controlled by network commands from RDL and other network remote controls. Each mixer operates independently with input signal attenuation from unity to off. The output level from each mixer is independently adjustable from unity to off. Based on the commands sent to the RU-NMP44, each mixer can be used as a mixer, a source selector, a priority paging inserter and/or as a volume control. The outputs from four of the mixers drive corresponding network audio channels whilst the outputs from two of the mixers drive line-level +4dBu audio outputs. RU-NMP44 can be configured using RDL Console or other compatible network control software.

Up to four preset configurations may be stored in the RU-NMP44, with each preset defining any or all mixer level settings. A preset is activated by a network command, an RDL network or wired remote control, a momentary switch closure or a compatible open-collector from other equipment. RU-NMP44 may be configured to power up to a preset, to the last settings used, or with all levels “off”. If ducking is used, one of the four network audio inputs is assigned as the priority input. That input is connected to all six virtual mixers.

An audio detector with installer-defined threshold and recovery delay may be assigned to one, several, or all of the six mixers. For each of those mixers, the priority input is set to a defined level, and the remaining three inputs are each set to attenuate to a fixed level between -10 and -64dB when a message is detected on the priority input. If hum is anticipated from the paging source, one of four high-pass filter may be enabled.

RU-NMP44 may be powered from an optional external 24Vdc power supply, or it has the ability to operate from a PoE enabled network switch.

Digital audio Ethernet protocol: Dante or AES67. Dimensions (WxDxH): 41.7 x 145.8 x 100.6mm.

Four-channel mono audio mixers in the popular RDL modular Rack-Up formats. Different models have four or five channels, microphone/line and line input types are offered.
