The RDL D-TPS3A Format-A Three-Pair Audio Sending Module is a professional audio interface designed to transmit microphone and line-level audio signals over twisted-pair cabling in commercial and installed sound systems. Featuring a balanced XLR microphone input with 24 V phantom power and two unbalanced RCA line-level inputs, the D-TPS3A provides a versatile solution for connecting multiple audio sources to an RDL Format-A audio distribution system.
Ideal for commercial AV installations, conference rooms, educational facilities, houses of worship, industrial environments, and distributed audio systems, the RDL D-TPS3A delivers reliable audio transmission with exceptional hum rejection, low noise, and minimal distortion.
The module features a studio-quality microphone preamplifier with rear-panel switch-selectable gain settings of 50 dB (normal) or 63 dB (high), accommodating different microphone signal levels. The balanced XLR microphone input transmits audio over Format-A Pair A, while the left and right RCA line-level inputs transmit independently over Pairs B and C, allowing three audio signals to be distributed through a single twisted-pair cable.
Designed for installation flexibility, the RDL D-TPS3A audio sender supports either local 24 VDC power or remote power supplied through compatible twisted-pair connections. A front-panel blue LED provides visual confirmation of module power, while its rugged construction makes it suitable for wall boxes, AV equipment racks, and industrial enclosures.
Whether you're integrating microphones into a conference room, distributing audio sources throughout a commercial building, or expanding an existing RDL Format-A twisted-pair audio system, the D-TPS3A provides dependable performance and professional-quality audio connectivity.
