Antenna Diversity

LCD Metering

Clear LCD display with real-time RF signal strength and audio level metering gives the operator a complete picture at a glance.

8-Hour Battery Life

Standard AA batteries deliver up to 8 continuous hours of operation — enough for the longest performances without a mid-show change.

100m Range

Up to 100 metres of line-of-sight range enables total freedom of movement across arena stages, outdoor festivals, and broadcast sets.
