Vivolink VLEXTA170 AV extender AV vysílač a přijímač černý

The Vivolink VLEXTA170 is an AV transmitter and receiver pair designed to extend audio signals over Cat5e/Cat6 (CATx) cable up to 100 m. It accepts TOSLINK, coaxial and stereo analogue inputs and supports a Power-over-Cable (PoC) function that can deliver power from the receiver to the transmitter. The unit is compact and suitable for integration in installations requiring wired audio distribution over longer distances.

Advantages

The VLEXTA170 provides loss-minimised audio transmission over a single CATx cable with support for multiple input formats (TOSLINK, COAX, stereo). Its PoC capability simplifies installation by removing the need for a separate power supply at the transmitter end. The compact black enclosure and standard AC input voltage (100–240 V) make it adaptable to various AV setups.

Suitable for

• Extending digital or analogue audio from source equipment to remote zones (up to 100 m)
• Installation in conference rooms, classrooms and small AV systems
• Setups where a single-cable run and remote powering reduce cabling complexity

How to use

Connect the audio source to the transmitter using the appropriate input (TOSLINK, COAX or stereo analogue). Run a CATx cable between the transmitter and the receiver up to 100 m. Connect the receiver to mains power (100–240 V AC); if PoC is supported and enabled, the receiver will supply power to the transmitter over the CATx cable, eliminating the need for a local power adapter at the transmitter. Finally, connect the receiver output to the destination audio system and verify signal and power indicators.

Recommendations

For reliable performance, use good-quality Cat5e or Cat6 cables and avoid running the cable parallel to high-voltage power lines. Verify compatibility of digital audio formats with source and destination devices. If PoC is used, confirm that the receiver provides PoC power and that the transmitter supports it to prevent power issues.
