The CB/12/W2040-EB-O from Hamilton is a complete 12-user wireless listening system. It consists of a wireless transmitter, 12 wireless beltpacks, and 12 pairs of earbuds.
Operation of the system is simple. Just connect the transmitter to the output of a tape player, CD player, or other audio device, and play your desired audio. The signal is broadcast by the transmitter and picked up by the beltpacks. The system has a wireless range of up to 300', allowing listeners a high degree of mobility. The beltpacks have standard headphone jacks, allowing you to use any standard headphones in place of the included earbuds if desired. Built-in volume controls allow each user to set their own volume level without affecting other listeners. Each beltpack can operate for up to 35 hours after an overnight charge.
The color of the transmitter and beltpacks indicates the wireless frequency. Four different colors are available, allowing you to use up to four different audio programs in the same space without interference.
