What is the RDL TX-TPS6A?
The RDL TX-TPS6A is a passive single-pair Format-A sender that transformer-isolates a +4 dBu balanced line source onto twisted pair cable. Because it needs no power, it suits distributed audio systems where local power is unavailable.
How does it work?

A low-impedance balanced source connects to the detachable terminal block, and a studio-quality transformer isolates it from the RJ45 output. A front-panel switch selects whether the signal drives pair A, B or C, and the module must feed pair A when combined with a two-pair stereo sender. A LOOP IN jack accepts signals and power from other Format-A senders, and power present there passes through to the output. Compatible Format-A receivers include the TX-TPR1A, TX-TPR6A and DS-TPR2A.
What are the key features?
- Passive operation — The module requires no power to operate.
- Transformer isolation — A studio-quality transformer isolates the audio source from the twisted pair cable.
- Selectable Format-A pair — A switch chooses which pair, A, B or C, carries the signal.
- Loop-in daisy chaining — A LOOP IN jack combines signals and power from other Format-A senders.
- Low distortion — RDL specifies 20 Hz to 20 kHz (±0.1 dB) response and THD+N below 0.035% from 50 Hz to 20 kHz.
