Simultaneous, two-way, wireless intercom system works well in an event-production scenario – allowing producers/directors to communicate immediately and accurately in full-duplex mode with crew members in different house locations. The director and assistant director can speak simultaneously, while crew members can hear both the director and assistant director. Crew members can participate as listen-only or can access two-way mode with the quick push of a button. The director has priority and controls the discussion. This system in the 2.4 GHz band offers a patented, frequency-hopping technology for low-noise, crystal-clear audio and less interference from other products. The dual-muff headset microphones are ideal for use in high-noise environments.
