HM Electronics BH800 Belt Pack

The HM Electronics (HME) BH800 (also widely identified by its interchangeable part number, the BP800) is a rugged, professional-grade wireless intercom beltpack that serves as the mobile user endpoint for the legacy HME System 800 (RW800 base station). Designed specifically for demanding live production, television broadcast, and theatrical environments, this beltpack allows camera operators, stage managers, and technical crew to maintain seamless communication across large venues. Operating in the analog UHF frequency band (typically between 450 and 470 MHz), it delivers strong, interference-resistant signal propagation that can easily penetrate stage walls, concrete corridors, and dense crowds—often outperforming modern high-frequency digital systems in structurally complex buildings.

Unlike basic two-way radios that require push-to-talk (PTT) operation, the BH800 utilizes true full-duplex communication. This allows multiple crew members on the intercom channel to talk and listen simultaneously, creating a natural, telephone-like conversation that is critical during fast-paced live events. The beltpack is housed in a heavy-duty, impact-resistant casing equipped with a sturdy belt clip, built specifically to survive the daily physical abuse of touring. It features dedicated volume controls, an intuitive user interface, and a standard 4-pin XLR connector to accommodate professional production headsets. Power is supplied by a proprietary, removable 4.8V 2000mAh Ni-MH rechargeable battery pack (commonly part number C10326 or K05645), ensuring extended operational time during long show calls.
