Sennheiser Microphones
Two EW 112-p G3 microphone sets are available. The microphone transmits a signal via a bodypack transmitter and a portable, battery-powered adaptive-diversity receiver. Both transmitter and receiver are simple and lightweight (160g each), as well as easy to operate, yet rugged. The transmitter and receiver are both 82 x 64 x 24mm in size.
The microphones and receivers both have sturdy metal housing and have a 42MHz bandwidth. They also have an auto-lock function to avoid accidental change of settings, programmable mute function, and user-friendly menu operation with more control options.
The microphone set includes a receiver, transmitter, 2 clip-on omnidirectional microphones, a jack cable, XLR cable, camera adaptor and operating instructions. The microphone operates on 4 AA batteries.
