Additional Information
The Hollyvox G51 beltpack (BP51) is part of Hollyland’s full-duplex ENC wireless intercom system, designed for productions that need reliable crew communication without the weight or cost of legacy analogue party-line comms. Operating in the 1.9GHz band with up to 400m line-of-sight range, it supports up to 3 groups with unlimited cascaded connections for larger crews.
Dual-mic environmental noise cancellation keeps voice clear even on loud stages or outdoor sites, and a 1500mAh battery gives up to 6 hours of use per charge, with 3.5mm, 0B10 and USB-C headset connections for flexibility across different headset types.
