Sennheiser EW 500 BOOM G4 Wireless Plug-On Microphone System for Cameras

Professional Wireless Audio for High-Stakes Video Production

The Sennheiser EW 500 BOOM G4 is a camera-mount plug-on microphone system crafted for filmmakers, videographers, and journalists who need broadcast-quality audio in demanding environments such as busy city streets. As part of the respected EW Series, this system delivers a highly capable and affordable solution built to perform reliably in challenging RF environments.

With its expansive 88 MHz operating bandwidth and up to 3520 UHF frequencies, the EW 500 BOOM G4 enables clean, interference-resistant transmission. Its adjustable RF output offers up to 50 mW of power, supporting as many as 32 simultaneous mic setups depending on regional regulations.

Flexible Plug-On Configuration for On-Camera and Field Use

At the core of the system is a plug-on transmitter that connects to your favorite handheld or shotgun mic via XLR. This includes 48 V phantom power so you can deploy condenser microphones with confidence. A locking ring secures the connection and the integrated mute switch gives fast, on-the-fly control on set.

The compact camera-mount receiver delivers crisp audio to your camcorder, cinema camera, or DSLR/mirrorless rig. With both XLR and 3.5 mm output cables included, you have the flexibility to integrate into a wide range of professional and consumer devices.

Durable Build Designed for Field Reliability

Built with rugged metal housings, both the transmitter and receiver are ready for extended location shoots. Displays on each unit provide battery level, signal strength, and audio level information in daylight conditions. The receiver mounts via a shoe adapter and can rotate 320 degrees to stay clear of accessories. A headphone output lets you monitor audio in real time while recording.

Advanced RF Management for Interference-Free Performance

The system automatically scans for the cleanest frequency when powered on and syncs transmitter and receiver via infrared with the push of a button. Switchable RF levels let you conserve battery life or boost signal strength as needed. The transmitter’s adjustable input sensitivity handles everything from hearty vocals to quiet speech or line-level signals. The receiver offers up to 42 dB output gain to match various camera inputs.

With adaptive-diversity reception, the system seamlessly switches between dual antennas to maintain strong signal clarity during movement or obstruction, extending reliable coverage up to 330 feet.

Broadcast-Quality Sound with HDX Compander Technology

Delivering studio-grade audio quality, the system uses Sennheiser’s HDX compander to preserve clarity and eliminate unwanted noise during RF transmission. This ensures your audio remains true to the original source, providing rich, detailed speech or dialog capture even in high-pressure shooting scenarios.

Designed for Real-World Use

Smart system features enhance usability. Battery-life indicators and auto-lock settings prevent accidental changes. The RF mute function prevents unintended transmissions when the transmitter is powered off. With up to 8 hours of runtime on AA batteries or compatible rechargeable BA 2015 packs, the system supports long sessions without downtime. Optional quick-charging solutions let you recharge the battery without disassembly. Even better, the SKP 500 transmitter can work with any number of EW Series receivers, allowing flexible configuration across large productions.

Compatible with Legacy EW Systems for Maximum Flexibility

The EW 500 BOOM G4 is backward-compatible with earlier Sennheiser Evolution Wireless systems (EW 100, G1, G2, G3). This interoperability enables creators to mix and match transmitters and receivers across generations and adapt to evolving production needs.
