Radio Design Labs D-TPSML1A Active Twisted Pair Sender

Product Description

The RADIO DESIGN LABS D-TPSML1A is an active single-pair sender designed to transmit balanced audio signals over twisted pair wiring. It converts a standard balanced or unbalanced audio source into a format suitable for transmission across Cat-type or equivalent twisted pair cable runs. This device is used by audio-visual technicians and systems integrators in fixed installation environments where signal integrity over longer cable runs is required. The active circuitry helps maintain signal level and reduce noise pickup across extended distances.

The D-TPSML1A is suited for professional audio distribution in commercial and institutional settings such as conference rooms, houses of worship, performance venues, and broadcast facilities. It functions as the send-end unit in a twisted pair audio extension system, pairing with a compatible receiver at the far end of the cable run. Installation is typically performed by licensed low-voltage contractors or AV systems integrators.

Key Features

• Active single-pair sender for balanced audio transmission over twisted pair cable
• Designed for fixed installation in professional AV signal distribution systems
• Helps preserve signal level and reduce interference over extended cable runs
• Compact form factor suited for rack, wall, or surface mounting in AV installations

Compatibility

Designed as an OEM-style sender unit for use in professional twisted pair audio distribution systems requiring an active send-end device.

Installation Notes

Installation is typically performed by a licensed low-voltage or AV systems contractor. Power down or de-energize the audio system before making connections. Follow applicable low-voltage wiring codes and the facility's AV system documentation. Do not connect to high-voltage circuits or use outside the rated operating parameters of the unit.
