Sennheiser EW 500 G4-945 Wireless Handheld Microphone System with MMD 945 Capsule (AW+: 470 to 558 MHz)

Sennheiser EW 500 G4-945 Wireless Microphone System: Precision Sound for Live Performances and Presentations

The Sennheiser EW 500 G4-945 is a high-performance wireless microphone system designed for professionals who need dependable audio quality and total control in live environments. Whether you're on stage, in a worship setting, teaching in a classroom, or presenting at a corporate event, this system delivers crystal-clear audio, seamless setup, and the flexibility to adapt to any situation.

Engineered for serious sound applications, the system includes a true-diversity half-rack receiver with a full-metal chassis that’s built to withstand the demands of live performance and touring. The EM 300-500 G4 receiver automatically scans a wide 88 MHz UHF tuning range and provides access to 3520 selectable frequencies. This makes it easy to find a clean, interference-free signal, even in crowded RF environments. The OLED screen offers a bright, high-contrast display with auto-dimming, while the intuitive jog wheel gives you quick access to key functions.

Paired with the receiver is the SKM 500 G4 handheld transmitter, which features the MMD 945 dynamic supercardioid capsule. Known for its tight pickup pattern and superior rejection of background noise, the MMD 945 excels in live sound settings where vocal clarity is a must. It captures every nuance of your voice while minimizing feedback, making it ideal for singers, speakers, and performers working on loud stages.

The handheld mic offers up to eight hours of continuous use on two AA batteries. With selectable RF power output levels of 10, 30, or 50 milliwatts, you can optimize the transmission range and signal strength to suit your venue. You’ll enjoy up to 330 feet of wireless coverage, giving you the freedom to move across the stage or presentation space without signal dropouts.

This system is ready for integration into more complex wireless setups. An Ethernet port on the receiver supports Sennheiser’s Wireless Systems Manager (WSM) software, which allows for remote monitoring, frequency coordination, and system control from your Mac or PC. The software is especially useful in multi-mic configurations, where up to 32 systems can run simultaneously in the same environment.

Backwards compatibility ensures you can use the EW 500 G4-945 alongside earlier Sennheiser evolution series gear, including G1 through G3 systems, as well as with EW 100 and EW 300 components. This makes it an excellent choice for upgrading or expanding your existing wireless setup.

The handheld transmitter is also equipped with an interchangeable capsule design. You can swap out the included MMD 945 for other Sennheiser capsules like the MMD 835, MMD 845, MME 865, MMD 935, or MMD 42, giving you the flexibility to tailor the sound for different applications and vocal styles.

The EM 300-500 G4 receiver supports detailed audio customization, including an onboard EQ for adjusting bass and treble response. Sennheiser’s HDX compander technology enhances the clarity of the signal while reducing unwanted noise. An adjustable output range of 48 dB ensures compatibility with a wide variety of mixing consoles and PA systems. Front-panel headphone monitoring and rear-panel XLR and 1/4-inch outputs provide convenient connectivity options, and the included rackmount kit and universal power supply make installation easy.

You can expand the reach of your wireless system using optional accessories like the ASA 214 active antenna splitter and external directional or omnidirectional antennas. These upgrades improve range and RF stability, especially in complex or high-traffic environments.

As your needs evolve, you can adapt the system using Sennheiser’s bodypack transmitters with compatible accessories. Discreet lavalier microphones like the ME 2-II or MKE 2 are perfect for spoken-word presentations, while the lightweight ME 3-II headset mic is ideal for active speakers and fitness instructors. For musicians, the Ci 1 instrument cable transforms the bodypack into a wireless solution for electric guitar or bass.

Whether you're building a professional live sound rig or looking to upgrade your wireless capabilities, the Sennheiser EW 500 G4-945 offers industry-leading performance, rock-solid reliability, and the flexibility to meet the demands of any stage.
