Sennheiser ew 500 G4 Wireless Instrument Microphone Set

The Sennheiser 509669 is a wireless instrument microphone set that gives guitarists and bassists the freedom to move across the stage without losing their tone. Built on the ew 500 G4 platform, it delivers the clarity and stability professionals expect in clubs, theaters, and touring rigs.

The kit includes an SK 500 G4 bodypack transmitter, an EM 300-500 G4 half rack receiver, a GA3 rackmount kit, and a Ci1 instrument cable that plugs directly into your guitar or bass. Together these components create a cable-free signal path from instrument to mixing console while keeping setup straightforward.

With a tuning range that spans 88 MHz and room for up to 32 simultaneous channels, the system performs reliably even in crowded frequency areas such as festival stages or broadcast heavy venues. True diversity reception inside a metal housing continually selects the stronger of two antenna signals, which greatly reduces dropouts.

Day to day operation is simple. Press the sync button and the infrared link transfers frequency, gain, and naming information from the receiver to the transmitter in seconds. If you manage several systems, connect them over Ethernet and use Sennheiser Wireless Systems Manager software for fast, offstage coordination.

Selectable RF output levels of 10, 30, or 50 mW let you match local regulations while maintaining the range required for small clubs or large arenas. The transmitter runs up to eight hours on two AA batteries, so a single set of cells can carry you from soundcheck through encore.

A metal chassis built for the road and a bright OLED display that shows frequency, link quality, and battery status give musicians and engineers confidence night after night. Whether you are stepping onto a festival stage, leading worship, or tracking in the studio, the ew 500 G4 Instrument Set keeps your sound balanced and present in the mix.
