Active Two-Pair Twisted-Pair Sender with XLR Mic and Stereo RCA Inputs – RDL D-TPSL2A

RDL D-TPSL2A — Active Two-Pair Twisted-Pair Sender (XLR Mic & Stereo RCA Inputs)

The RDL D-TPSL2A is an active two-pair sender designed to transmit audio from common studio and consumer sources over Format-A two-pair twisted-pair cabling. It accepts a balanced XLR microphone input alongside stereo unbalanced RCA inputs, enabling a single device to handle both mic and line-level sources. By converting these inputs to a Format-A two-pair twisted-pair output, the unit addresses installation challenges where long or consolidated cabling runs are required. The active electronics ensure proper signal conditioning for reliable transmission over twisted-pair cable. This sender is useful when conventional XLR or RCA cabling is impractical or when integrating audio into existing twisted-pair infrastructure. The D-TPSL2A is built for professional installation environments and system integration projects where straightforward, dependable audio distribution is needed.

Key Features:

• Active two-pair sender for Format-A twisted-pair audio distribution
• Balanced XLR microphone input
