Reliable sound over long distances

The RF Venue RF PA Extension Kit is a wireless audio system designed to streamline PA deployments by eliminating cable clutter. It enables flexible, long-distance setups that would otherwise be impractical or impossible due to difficult cable routing – with clear line-of-sight, a range of nearly 100m is possible. Frequency synchronisation between the transmitter and its receivers is handled at the push of a button within the 2.4GHz wireless band. The receivers' rugged housings are IP44‑rated, providing protection against dirt and water, so they can be used outdoors under everyday conditions. An integrated delay feature also enables straightforward configuration of a delay line. Additional receivers can be purchased to expand the system's scale as required.

A wide range of applications

To ensure optimum sound quality even in challenging on‑site conditions, the RF Venue RF PA Extension Kit operates with True Diversity reception. Because each receiver can either output the same stereo signal or one of the two mono channels, a wide range of applications are feasible, from L/R setups on large stages to more complex tasks such as feeding dual zones or extending coverage across distributed loudspeaker arrays. With a maximum delay time of 800ms, the system can be used to set up a delay line that distributes daisy-chained speakers over distances of up to 274 metres. Balanced combo inputs on the transmitter ensure clean signal paths, with balanced loop‑outs for sidefill monitors or a backstage feed. To make all this straightforward, key parameters – such as group, channel, antenna selection, and sync status – are shown on the LCD screens of the transmitter and its receivers.

RF Venue RF PA Extension Kit

Perfect for pros and amateurs

The RF Venue RF PA Extension Kit is a PA wireless solution that's perfect for musicians, DJs, mobile entertainers, event service providers, and festival organisers. It's an ideal solution wherever reliable, cable‑free audio flexibility is required, bridging even long distances wirelessly. Conference teams, crews working on municipal events, and open‑air operators will find it to be a highly effective wireless system for any sound reinforcement setup, as it can be deployed in changing configurations much more easily than when working with cabling. Experienced users seeking perfect audio synchronisation will appreciate the system's delay function. Because no complex audio network needs to be configured – just the wireless link between the devices themselves – the RF Venue RF PA Extension Kit is suitable not just for professionals but also for advanced amateurs.

Lange auf so ein Produkt gewartet

Alles, was es bis jetzt im normalen Handel an Funklösungen gab ist gegen das System Spielzeug. Im Freien habe ich das System bis 250m um Häuserecken herum getestet, super Sound, keine Abbrüche. Ideal in Verbindung einer EV Everse Akkubox, dort kann der 12V Anschluss direkt mit dem Empfänger gekoppelt werden.
Ich werde definitiv weiter Empfänger bestellen.
Einziger Kritikpunkt: die vorderen BNC Anschlüsse hatten einen Wackelkontakt, konnte aber in Eigenregie schnell repariert werden.
