Active Three-Pair Twisted-Pair Sender, Format A, Balanced Inputs – RDL TX-TPS3A

RDL TX-TPS3A — Active Three-Pair Twisted-Pair Sender with Balanced Line Inputs

The RDL TX-TPS3A is an active three-pair sender designed to transmit balanced audio signals over twisted-pair cable using the Format-A wiring convention. It accepts balanced line-level inputs and conditions those signals for reliable long-distance transmission on standard twisted-pair infrastructure. By using balanced inputs, the sender helps minimize hum and interference, preserving audio fidelity for paging, distribution, and remote audio feeds. The three-pair arrangement consolidates multiple channels onto a single cable run, reducing cable bulk and simplifying rack-to-rack or floor-to-floor connectivity. Installers and integrators benefit from predictable wiring and consistent channel separation that speeds field termination and troubleshooting. OEM buyers and MRO teams can deploy the TX-TPS3A as a repeatable, serviceable component for retrofit work, spare-part inventories, or custom audio products. Electronics hobbyists will also find the unit useful for experiments and small-scale remote audio links where balanced transmission is preferred.

The sender is intended to mate with compatible receivers or baluns that restore the balanced audio at the far end, following Format-A pair assignments. Clear, purpose-built functionality makes the TX-TPS3A a practical option where low-noise, multi-channel twisted-pair transport is required.

Key Features:

• Active three-pair sender compatible with Format-A twisted-pair wiring
• Balanced line-level inputs to reduce noise and preserve signal integrity
• Consolidates three independent audio channels onto twisted-pair cable

Specifications:

• Manufacturer: RDL
• MPN: TX-TPS3A

Typical Applications:

• Multi-channel audio distribution in commercial AV systems
• Paging, intercom, and background music installations using twisted-pair backbone
• OEM integration and MRO spare inventory for audio products
• Electronics bench testing and hobbyist remote audio projects

Installation or Use Example: During a facility audio upgrade, a field technician routes a single Format-A twisted-pair backbone between equipment rooms, connects three balanced outputs from a mixer to the TX-TPS3A, and verifies each channel at the remote receiver. The consolidated cabling and balanced connections reduce installation time and simplify ongoing troubleshooting.
