RDL RU-TPS4A – Active Format-A Audio Sender/Distributor with Three Inputs and Four Outputs

The RDL RU-TPS4A is an active audio sender and distributor module designed for professional AV installations, compatible with RDL’s Format-A twisted pair system. It accepts three independent line-level sources (balanced or unbalanced) and distributes them to four RJ45 Format-A outputs, while powering all connected receivers.

Each audio channel is assigned to one Format-A pair (A, B, C) and features individual front-panel level adjustment. Studio-grade buffer amplifiers ensure optimal signal quality. Three dual-LED VU meters provide real-time monitoring of each audio pair.

RU-TPS4A powers all connected Format-A modules, with each output protected by an auto-resetting fuse. Rear-panel LEDs indicate proper voltage at each RJ45 output. The RACK-UP chassis allows mounting of three modules in a single rack unit, and the built-in power bus simplifies expansion with adjacent distributors.
