AU680 Wireless Audio Transmitter & Receiver Kit – 1 Receiver

Wireless audio without a long signal cable

Connect an audio source to compatible output equipment with the AU680 wireless audio transmitter and receiver kit. Whether you are setting up a meeting room, classroom or home audio system, the dual-antenna design helps you position equipment without running a long audio cable between the transmitter and receiver.

Kit configuration and plug choices

This kit includes one transmitter and one receiver. Choose an EU, US, UK or AU plug option to match your power outlet. This listing is the single-receiver kit, not the 2–5 receiver bundle.
