Additional Information
The Hollyland Hollyvox G51 is a full-duplex wireless intercom system built for production teams who need reliable, hands-free communication across a busy show or event site. Operating on the 1.9GHz band with GFSK modulation, it delivers clear two-way audio with environmental noise cancellation (ENC) built into every beltpack, keeping crew talk audible even in loud venues or outdoor environments.
This 4-beltpack configuration ships with single-ear headsets and supports up to three separate communication groups with unlimited cascade connections, making it easy to scale for larger crews. Each beltpack runs up to 6 hours on its 1500mAh lithium battery, with the full 8-unit charging base topping up a complete set in around 2.5 hours, so units can be rotated through a full shoot or event day without downtime.
