Passive Single-Pair Twisted-Pair Sender, Format A, Balanced Line Input – RDL TX-TPS6A

RDL TX-TPS6A — Passive Single-Pair Sender, Format A, Balanced Line Input

The RDL TX-TPS6A is a passive single-pair sender designed to transmit a balanced audio or signal line over a Format-A twisted-pair cable. As a passive device, it requires no power and provides a simple, reliable interface between a balanced line-level source and a twisted-pair run. The unit is intended to preserve signal integrity while enabling longer cable runs and easier wiring practices in installations that use standard Format-A pair mapping. Installers and integrators will appreciate the straightforward wiring and compact form factor that simplify rack or junction-box mounting and reduce installation time. Because it is passive and connection-focused, the device is well suited for replacement, retrofit, or new installations where a powered line driver is unnecessary. The TX-TPS6A is useful in environments where maintaining balanced audio performance across twisted-pair infrastructure improves noise rejection and overall system reliability.

Specifying the TX-TPS6A helps streamline connectivity in commercial AV, distributed audio, and other low-voltage signal projects. Its passive operation reduces points of failure and ongoing maintenance for MRO teams and OEM assemblies. Tri-Tek Electronics stocks and distributes RDL products for customers in Mesa, Phoenix, Chandler, Tempe, Gilbert, Scottsdale, Glendale, and nationwide.

Key Features:

• Passive single-pair sender for Format-A twisted-pair wiring
• Accepts balanced line input for improved noise rejection
• No external power required — passive operation

Specifications:

• Manufacturer: RDL
• MPN: TX-TPS6A

Typical Applications:

• Field AV installations requiring balanced audio over twisted pair
• Audio distribution and signal routing in commercial or institutional projects
• OEM assemblies and MRO replacement parts where passive senders are specified
• Retrofit and upgrade projects using Format-A twisted-pair infrastructure

Installation or Use Example:

• An AV technician installs the TX-TPS6A at an equipment rack to send a balanced line-level output from a mixer over existing Format-A twisted-pair cabling to a remote receiver; the passive sender is wired to the mixer’s balanced output and connected to the pair mapped on the building’s twisted-pair run, simplifying the installation and avoiding the need for local power at the sender location.
