RDL TX-TPSA1A – Three-Pair to Single-Pair Format-A Active Combiner

RDL TX-TPSA1A is a professional Format-A module that actively combines audio signals from three twisted-pair channels (A, B, C) into a single output pair. Designed for AV installations requiring signal consolidation, it ensures high-quality audio transmission and seamless integration with other Format-A devices.

The front-panel RJ45 input receives audio and power from one or more Format-A senders. Signals on all three pairs are actively summed and routed to a single output pair (A, B, or C), selectable via a front-panel switch. The LOOP IN jack passes through the remaining two pairs and power, allowing daisy-chaining of additional Format-A modules.

The module can be powered via any of the three RJ45 jacks or through an external 24 V DC supply. An auto-resetting fuse protects the output voltage, and a blue LED indicates valid power. Studio-grade active balanced circuitry ensures clean, isolated signal mixing.
