​The PU-305BDA-TX is an analogue Stereo over CAT5e/6/7 Transmitter which can send and receive analogue audio signals over a single run of CAT5e/6 cable up to 300m. It has the added benefit of RS-232 pass-through allowing control of devices and the Power over Ethernet (PoE) function can power the receiver unit eliminating the need for a second power supply. As the unit has bi-directional capabilities, this device can also receive audio signals back from the connected receiver.

This transmitter is designed to be used with the PU-305BDA-RX Analogue Audio Receiver or the PU-305BD-RX Digital Audio Receiver. When combined with the PU-305BD-RX digital receiver, the analogue audio signal will be converted and outputted as digital audio by the receivers' built-in digital to analogue converter (DAC).
