I/ Bộ thu hình và máy phát Sennheiser EW 500 BOOM G4

The ew 500 G4 Wireless Plug-On System from Sennheiser is the latest addition to their evolution series of wireless systems. It operates in the UHF frequency range and can be used with a condenser shotgun or a handheld microphone (sold separately), as part of a wireless RF transmission system for ENG (Electronic News Gathering), presentation, and live stage applications.

The camera-mount receiver—with adaptive diversity technology—features 2000 selectable frequencies (50 MHz) and is tunable in 25 MHz steps. There are 20 fixed-frequency banks with up to 32 compatible frequency presets and 6 user banks with up to 32 user-programmable frequencies.

Furthermore, the plug-on transmitter features 48V phantom power to power condenser microphones and is synchronized with the camera-mount receiver via an integrated infrared interface. Both units are powered by two 1.5V AA sized batteries.
