Silent Disco Transmitter — 1500ft Range

This RF transmitter delivers wireless audio up to 1500 feet with no lip-sync delay, supporting up to 100 headphones simultaneously. Three selectable channels let groups switch between different audio streams. It is built for silent discos, campus events, and group TV listening where wired connections are impractical.

Upgrade From Wired Or Single-Channel Systems

Replaces cabled headphone distribution and single-channel wireless kits that limit listener count or channel choice. The jump is worth it when you need to cover a large venue, serve dozens of listeners at once, or offer multiple audio programmes without running new cables.

Plug-In Setup With Steel Housing

Connect the included AC adapter and RCA-to-AUX cable to your source, then power on and select a channel via the backlit display. The rugged steel case and supplied travel case protect the unit during transport. Ensure the source device has an RCA or AUX output; units without that connection will need an adapter not included.
