Description:
The RDL DD-BN2ML Wall-Mounted Bi-Directional Mic/Line Dante Interface provides all necessary audio connectivity for this meeting room and is networked with a centrally-located Dante-enabled DSP. The XLR input provides three switches that are set from the front of the unit before the cover plate is installed. One switch enables or disables P48 phantom; the second switch selects the mic or line gain range; the third switch sets the gain. The 3.5mm input sums the left and right channels of a stereo source to mono to feed one Dante network transmit channel. The two male XLR connectors on the D-XLR2M wall plate are wired to the two line level outputs on the rear of the DD-BN2ML to feed the two active loudspeakers. The DD-BN2ML and D-XLRM2 are shown mounted together in a triple-gang RDL surface-mounted box.
INTERCOM USING DECORA®-STYLE LOUDSPEAKERS
Remote Decora Loudspeakers Serve Dual Duty as Microphone and Speaker
AN-2240
Description:
Two RDL D-SP1A Decora-style wall-mounted loudspeakers are used in this intercom system. The control station uses the speaker for monitoring. The remote station uses the D-SP1A as both microphone and speaker, switched by an RDL ST-LCR1 Logic Controlled Relay. Signal amplification and muting is provided by a pair of RDL ST-IC1 Intercom Amplifiers. The D-SP1A simplifies the physical installation and provides superior audio clarity to similarly-sized loudspeakers. The control station is equipped with a push-to-talk microphone to control the direction of the conversation.
NETWORKED AUDIO - ADDING NEW CHANNELS
BGM and Paging Audio Transmitted Between Buildings Over Existing Network
AN-2228
Description:
Dante networked audio is ideal for audio systems with large channel counts and is equally beneficial in much smaller systems. Cost savings can result from utilizing Dante to transport one to four channels of audio over an existing Local Area Network which would otherwise require the installation of dedicated audio cable between buildings in a school, hospital, church, office complex or factory. This diagram shows background music and a paging microphone sent via Format-A directly to a local Mixer-Amplifier in the main building. The Format-A cabling also sends these sources to the RU-FNP Format-A to Network Interface which converts the two sources to two Dante network channels. The signals travel through the network to the satellite building(s) where they are converted back to audio by the FP-NML2 Network to Mic/Line Interface to feed the BGM and Paging inputs of a Mixer-Amplifier.
Description:
A Dante network is used to distribute several sources of facility-wide paging to multiple buildings. Within each building (one is shown), networked audio is converted to RDL Format-A for distribution to three floors using an RU-NFD Network to Format-A Interface/Distributor. Each paging source is routed to Format-A Pair A, Pair B or Pair C through Dante Controller. The RU-NFD provides three Format-A output jacks that each send audio on pairs A, B & C to a twisted pair receiver on one floor, then in turn to additional receivers on the other two floors. By setting each TX-TPR1A receiver to a different receive pair (A, B o
