DB-TPS2A

RDL DB-TPS2A – Active Two-Pair Audio Sender Format-A with RCA Inputs

The RDL DB-TPS2A is an active audio sending module designed for professional AV installations, compatible with RDL’s Format-A twisted pair system. It features two unbalanced RCA inputs for left and right channel audio sources, transmitting signals to cable pairs B and C. Its compact design allows for wall box mounting, making it ideal for conference, education, and commercial environments.

The module uses studio-quality active buffering circuitry to ensure optimal audio performance and signal integrity. Power can be supplied locally via a terminal block or remotely through the twisted pair cable. An integrated auto-resetting fuse protects against overloads, and a front-panel LED indicates power status.

With pass-through RJ45 jacks and compatibility with single-pair senders, the DB-TPS2A offers flexible integration into larger Format-A systems. It supports daisy-chaining and feeds both signal and power to connected modules.
