Sennheiser EW 500 G4-945-AW+ Wireless Vocal Microphone Set

The Sennheiser 509782 is a wireless vocal microphone set that gives live performers and audio engineers a dependable way to capture voices on small club stages, large touring rigs, and everything in between. It builds on Sennheiser’s well-known evolution wireless series, offering the freedom of a handheld transmitter combined with the control of a half-rack receiver.

An 88 MHz tuning range allows up to 32 channels to operate at the same time, which makes the system a strong choice for festivals, houses of worship, and corporate events that need many open frequencies inside one venue. The metal receiver features true diversity reception and an OLED screen, so you can check RF strength, audio levels, and battery status at a glance even in dim stage lighting.

Pairing the handheld transmitter and receiver takes only seconds thanks to infrared sync. When a show calls for complex coordination, the built-in Ethernet port links the receiver to Sennheiser’s Wireless Systems Manager software, letting technicians scan the spectrum, assign frequencies, and monitor every channel from a laptop at front of house.

The included SKM 500 G4 handheld transmitter houses a dynamic capsule with a cardioid pickup pattern. This design focuses on the performer’s voice and reduces bleed from drums, guitar amps, or stage monitors, which helps front-of-house mixers deliver sound that is both clear and powerful without fighting feedback.

RF output can be set to 10, 30, or 50 mW, giving you options for short-range gigs, crowded RF environments, or long cable-free runs across festival stages while still meeting local regulations. An eight-hour operating time keeps the show running through headline sets, rehearsals, and encores.

The package ships ready for the road with a rackmount kit, two rod antennas, and a universal power supply. Operating in the 470 to 558 MHz range, the system adapts to many regional TV-band allocations, making it a practical choice for touring acts and rental companies.
