Flexible multi-channel audio setup
The SubZero UHF 3-Channel Silent Disco Transmitter features an RCA stereo input for audio devices and a 3.5mm microphone input. These can be used individually or simultaneously, giving you flexibility over what’s broadcast to your audience.
The transmitter operates on one of three selectable frequencies, matched to the three received frequencies on the SubZero Silent Disco Headphones. By using up to three transmitters simultaneously - each set to a different frequency - you can deliver separate audio streams, such as different music genres, live commentary or translations, across multiple channels. Listeners can switch between these effortlessly on their individual headset, creating a personalised listening experience for festivals, conferences, and private events.
If you're looking for a complete silent disco setup, a custom bundle combining transmitters, headphones and chargers is available here.
Ranges to suit any event
Designed for both indoor and outdoor use, the SubZero UHF 3-Channel Silent Disco Transmitter adapts to events of all sizes. A high/low power switch lets you control signal strength to match your setup. High-power mode delivers maximum range (500m), ideal for expansive spaces like festivals or large conferences, while low-power mode reduces range (75m) and conserves battery for off-grid events, perfect for smaller venues or outdoor use.
The strong UHF signal ensures reliable, interference-free audio, so attendees can move freely while enjoying a smooth and consistent listening experience.
Battery-powered operation for ultimate portability
The SubZero Silent Disco Transmitter features a built-in rechargeable battery, providing up to six hours of uninterrupted use. This makes it perfect for events in locations without mains power, such as outdoor festivals, remote venues, or pop-up installations. A four hour charging time minimises downtime, giving event organisers a reliable, portable solution for any audio setup.
Unlimited headphone connectivity
Designed to accommodate events of all sizes, the system supports an unlimited number of compatible SubZero Silent Disco Headphones. Whether it’s a small group activity or a large-scale festival, every attendee can connect and choose their preferred channel.
