Additionally, in the presence of RF interference, the GLX-D receiver and transmitter will seamlessly move together to clean frequencies with no audio signal interruption. Each GLX-D transmitter is powered by a custom, intelligent lithium-ion battery for up to 16 hours’ continuous use at full charge.
