Overview
The EM 300-500 G4 Wireless True Diversity Receiver from Sennheiser is a part of their evolution series, designed for live stage, theatre, and presentation applications. It operates in the UHF frequency range and works with a companion transmitter and microphone (sold separately).
Core Features
The half-rack receiver features 3250 frequencies, tunable in 25 kHz steps. It includes 20 fixed frequency banks with up to 32 compatible frequency presets and 6 user banks with up to 32 user programmable frequencies. The menu-driven backlit OLED display shows current frequency, frequency bank and channel number, RF level, volume level, line output level, lock status, battery status, and muting function.
Connectivity & Control
Enclosed in a rugged metal housing, the EM 300-500 G4 receiver is equipped with a balanced XLR-3M audio output and an unbalanced 6.35 mm audio output. A 6.35 mm headphone output with volume control is provided, along with an Ethernet port (RF45) for remote network-based monitoring and control using Sennheiser's Wireless System Manager software. Two BNC-type sockets are available for connecting the antennas. The receiver operates on the included 12V power supply and includes a GA3 rackmount set.
