Wireless ifbs (wireless talent cueing) help any live or recorded broadcast run more smoothly, enabling the talent to react to direction on set. However, the price for a good ifb system is out of reach for most people. We are happy to introduce VocoPro silent-pa-ifb system! It is a game changer in both price and functionality. It costs less than 1/5 of the price of leading wireless ifb system. And you will still get the same clear sound and long range. The straightforward design is easy to use and requires no synchronization or set-up. Our basic ifb system comes with one transmitter for the director and 4 receivers for the talent. Additional packages include 12 receivers, or 30 receivers. Use one transmitter to send out audio to multiple receivers, or use Additional transmitters with different frequencies to send out to different team on the Set.
