Professional videographers know, it's much better to have the mic close to your subject than having it stuck on the camera. You will capture much clearer and cleaner sound from your talent. Vocopro’s Field-Quad and Field-Quad-Film wireless mic systems allow 4 to 16 users to send their voice loud and clear simultaneously via 24-bit digital transmission. The handy built-in mixer lets videographers control volume and balance on the fly via the 3.5mm mixed out or use the four independent balanced outputs to connect to a field mixer. Available in 4, 8, 12, and 16 channel configurations with lavaliere or handheld microphones. It requires no set up or sync, just insert fresh batteries* power it up and play. *AA batteries not included
