The Q+ system includes the QX-6A wireless intercom master station and from 1-6 QTR-2 belt packs. QX-6A master station and belt packs work in the high VHF frequency range of 150-216 MHz. The Q+ system offers hands free, full-duplex, continuous communication. Up to six people can be equipped with wireless FM belt pack remotes on the Q+. The QX-6A master station can connect into virtually any wired system-- typically Clear-Com, RTS, Telex and ROH. When the QX-6A is connected into a hardwired intercom system, the number of master stations and belt pack remotes (six per station) is limited only by the number of available frequencies.
