Introducing the VocoPro SilentPA-IFB-4 One-Way Wireless IFB Communication System, a budget-friendly and versatile option for film production or live and recorded broadcasts. This system offers similar clear sound and long-range capabilities as leading wireless IFB systems, but at a fraction of the cost. The SilentPA-IFB-4 includes one transmitter and one headset mic for the director, plus four receivers for the crew, with the option to purchase additional packages that can accommodate up to 12 or 30 receivers. Multiple transmitters with different frequencies can also be used to send audio to different teams on set.
