Product Description

The EM 300-500 G4-AW+ is a premium rackmount wireless receiver offering the widest frequency range in the G4 lineup—an impressive 88 MHz spanning the AW+ band from 470 to 558 MHz. This bandwidth enables up to 32 compatible channels operating simultaneously without interference, making it indispensable for large productions, broadcast facilities, and houses of worship. True diversity reception with dual antennas and tuners provides robust signal handling in complex RF environments. The front panel display delivers clear readouts of RF level, audio level, transmitter battery life, and active frequency. Balanced XLR and unbalanced jack outputs accommodate professional mixing consoles and recording systems. Automatic frequency scanning makes channel setup fast even in RF-congested venues. The EM 300-500 G4 supports Sennheiser's Wireless Systems Manager (WSM) software for networked frequency coordination and remote system monitoring. Its half-rack form factor combines with the GA 3 adapter for compact dual-unit racking. HD Clear Audio mode further extends dynamic range for superior audio performance.
