Sennheiser EW 500 G4-935 Wireless Handheld Microphone System - AW+ Band - 509781

Product Overview

The Sennheiser EW 500 G4-935 is a tour-grade UHF wireless handheld microphone system combining the SKM 500 G4 transmitter with the proven e935 dynamic cardioid capsule and the EM 500 G4 half-rack true diversity receiver. Operating in the AW+ band (470–558 MHz), it provides 88 MHz of tuning bandwidth and up to 3,520 selectable frequencies for interference-free wireless in congested RF environments. The system delivers professional-grade vocal sound with the reliability expected on touring stages, in houses of worship, and in fixed-install AV applications. At $999, it represents the 500-series platform's ideal balance of capsule performance, system flexibility, and rackmount convenience.

Product Description

The EW 500 G4-935 builds on the proven evolution wireless G4 platform, pairing the robust SKM 500 G4 all-metal handheld transmitter with the e935-S dynamic cardioid capsule — one of Sennheiser's most trusted live vocal transducers. The e935-S delivers smooth, natural vocal reproduction with a fast transient response and solid resistance to handling noise, characteristics that make it reliable in the hands of any live performer. The EM 500 G4 receiver occupies a single half-rack space and provides true diversity reception, with independent antenna switching that eliminates RF dropout over ranges up to 330 ft. line-of-sight. The HDX compander maintains signal clarity by minimizing compander artifacts, and the OLED display with automatic dimming ensures readability under any stage or house lighting. Auto-frequency scan searches the band for clear channels, while IR sync instantly pushes frequency and parameter settings from receiver to transmitter without manual entry. Pilot tone squelch mutes the audio output when the transmitter is powered off, preventing RF noise bursts through the PA. The EM 500 G4's Ethernet port enables connection to Sennheiser's free Wireless Systems Manager (WSM) software for remote frequency coordination and monitoring across up to 32 simultaneous channels. The system is backward-compatible with G1, G2, and G3 evolution transmitters and receivers. In the box: EM 500 G4 rackmount receiver, SKM 500 G4 handheld transmitter with e935 capsule, GA 3 rack kit, NT 2 power supply, two antennas, and a mic clip.

Frequently Asked Questions

Q: What capsule does the EW 500 G4-935 include?

The system includes the e935-S dynamic cardioid capsule, which provides smooth, natural vocal reproduction with fast transient response and high resistance to handling noise. It is one of Sennheiser's most widely used live vocal capsules.

Q: What frequency band is SKU 509781?

SKU 509781 is the AW+ band variant, covering 470–558 MHz. This band provides 88 MHz of tuning bandwidth with up to 3,520 selectable frequencies for operation in congested RF environments.

Q: How do I sync the transmitter to the receiver?

Point the transmitter's IR window at the receiver's IR port and press the sync button on the receiver. All frequency and parameter settings transfer from receiver to transmitter automatically within seconds.

Q: How many simultaneous channels can I run in one venue?

Up to 32 intermodulation-calculated channels can operate simultaneously within the AW+ band. Sennheiser's free Wireless Systems Manager (WSM) software assists with frequency coordination for large channel counts.

Q: Is this system compatible with my existing evolution G3 equipment?

Yes. The EW 500 G4 platform is backward-compatible with G1, G2, and G3 evolution series transmitters and receivers, allowing you to integrate it into an existing evolution wireless setup.

Q: What outputs does the EM 500 G4 receiver have?

The receiver provides a balanced XLR output and a 1/4" output. Both can connect to mixing consoles, powered PA systems, or audio interfaces. Output level is adjustable via the receiver menu.

Q: Can I use rechargeable batteries?

Yes. The SKM 500 G4 transmitter accepts the optional Sennheiser BA 2015 rechargeable accupack in addition to standard AA batteries, providing approximately 8 hours of operation per charge.

Q: What is pilot tone squelch and why does it matter?

Pilot tone squelch detects when the transmitter is powered off and automatically mutes the receiver's audio output, preventing RF noise bursts from reaching your PA system during performer entrances and exits.
