Saramonic WiTalk9 WT9S Wireless Intercom System for 9 Users

The Saramonic WiTalk9 WT9S is a full‑duplex wireless intercom system that keeps production crews, live‑event teams, and broadcast staff in constant, hands‑free communication. Operating interference‑free over a long 1,640‑foot (500‑meter) range, this professional intercom delivers reliable, crystal‑clear audio while giving each user complete mobility on set.

Each lightweight headset weighs just 8.0 oz and includes a replaceable 1,450 mAh lithium‑polymer battery, providing up to 10 hours of runtime for the master unit and 15 hours for every remote. Saramonic’s ClearTalk™ three‑mic array noise‑cancellation algorithm (up to 50 dB of suppression) ensures voices cut through even loud environments, while IPX5‑rated housings, dual antennas, and adaptive frequency hopping maintain secure, dropout‑free links indoors or outdoors.
