When camera, lighting and direction are spread across a stage or location, timing beats shouting. The Accsoon CoMo 1H6R is a 7‑person wireless intercom headset kit with one host and six remote headsets for hands‑free talkback in cinema, broadcast and streaming crews. It runs in the 1.9 GHz band and keeps everyone in the same group with full‑duplex audio—speak and listen at the same time—out to 400 m line‑of‑sight (site conditions permitting). An external antenna on each headset helps maintain a reliable connection when the team splits into different zones.
Speech intelligibility is the point: dual‑mic ENC attenuates ambient noise while keeping consonants readable, and the flip‑to‑mute microphone lets you cut the mic instantly for a private note. Frequency response is specified at 150 Hz–7 kHz with >65 dB SNR, matching voice bandwidth without the brittle edge that causes fatigue. Single‑ear, over‑ear construction leaves one ear available for room sound, and the boom can be placed on the left or right. Accsoon also specifies zero sound leakage, useful on drama takes or in galleries where you can’t spill chatter into the room.
Beyond the 1H6R package, the system links up to 9 headsets per group (1 host + 8 remotes); the host stores pairing and rebuilds the connection automatically after a signal loss. Controls stay direct: power, pairing, 7‑step listening volume, and an ENC button (enabled by default). For complex venues—double stage, separate camera unit and RF team—two independent CoMo groups can work in the same area without mutual interference, so comms stay separated without adding a base station.
Power is handled with 2320 mAh swappable batteries: remotes are rated for 13 hours, while the host runs 10 hours with 4 remotes or 8 hours with 8 remotes connected; recharge time is ≤ 2 hours. Kits ship with spare batteries, multi‑bay charging and a storage container, which matters when call time is before sunrise. Deploy it for multi‑camera live shows (director ↔ camera ops ↔ shader), on‑set coordination between producer and roaming operator, or studio/venue comms for broadcast TV, reality production and livestreams. Specified operating temperature: −15 to 45 °C.
