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-XLR2M are shown mounted together in a triple-gang RDL surface-mounted box.

Description:
All audio processing in this briefing room is handled by a centrally located Dante-enabled DSP. The RDL DD-BN2M Bi-Directional Mic/Line Interface connects the two microphones and the two permanently installed D-PSP1 Decora-Style Active Loudspeakers to the Dante network. Each D-PSP1 serves as a near-field monitor and is fed from the line-level outputs on the rear of the DD-BN2M. Each 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.
TWO MIC INPUTS FEED DANTE™ NETWORK OVER CATx
Dual Mic Preamp Provides 48 V Phantom and Automatic Gain Setting
AN-2239
Description:
The D-TPSM2A Dual Microphone Preamplifier is installed in the meeting room for users to connect one or two wired microphones. The module provides 48 V phantom and is compatible with both dynamic and condenser microphones. Rear panel GAIN switches for each channel are set to AUTO by the installer to automatically provide 60 dB of gain for dynamic mics or 40 dB for condenser mics. The D-TPSM2A output feeds the preamplified microphone signals to two Format-A pairs. The output cable loops through a D-TPSL1A interface which accepts a mono or stereo audio source that it sums to mono. The mono output from the D-TPSL1A feeds the remaining Format-A cable pair. The Format-A cable terminates into an RU-FN Format-A to Network Interface module that converts the sources to three Dante network channels. The line-level output of a wireless microphone receiver is connected to the Aux Input of the RU-FN to feed its fourth Dante output channel. The Format-A input modules are both powered from the RU-FN. A single CATx cable run is the only installed cabling required for audio inputs in this meeting room.
