Sennheiser EW 100 G4 – Professional Wireless Microphone System

The Sennheiser EW 100 G4 is a professional wireless microphone system from Sennheiser’s Evolution Wireless series, the G4 being the fourth generation of a platform that has been trusted by live performers, broadcasters, video producers, and event sound engineers worldwide for over two decades. Building on the Evolution Wireless legacy with improved RF technology, enhanced frequency agility, and a refined user interface, the EW 100 G4 provides reliable, clear wireless audio in demanding live and studio environments. Whether used for live vocal performance, presenter wireless for conferences, instrument pickup, or video production, the EW 100 G4 delivers the professional-grade audio quality and operational reliability that Sennheiser’s Evolution Wireless series is renowned for.

UHF Wireless Technology and Frequency Agility

The EW 100 G4 operates in the UHF frequency band, with multiple frequency bands available to comply with local spectrum regulations across different territories. Within its operating band, the system offers up to 42MHz of switchable bandwidth with 1680 tunable frequencies, providing exceptional flexibility to avoid interference from other wireless systems and broadcast signals at busy venues. Sennheiser’s auto-scan function automatically searches the available spectrum and selects the clearest channel, simplifying setup at venues with complex RF environments. The EW 100 G4 system also supports synchronisation via infrared between the transmitter and receiver for rapid frequency matching during setup.

Reliable RF Performance and Range

Sennheiser’s Evolution series RF design has always prioritised signal reliability in challenging environments, and the EW 100 G4 continues this tradition with a transmission range of up to 100 metres in open space. True diversity receiver design uses two antenna inputs with continuous signal comparison to select the stronger signal, virtually eliminating the dropouts and artifacts associated with multipath RF interference in enclosed spaces with reflective walls and obstacles. The automatic frequency management system continuously monitors the RF environment and can reroute to a clear frequency if interference is detected during operation.

Transmitter Options and Audio Quality

The EW 100 G4 is available in configurations including handheld (with e835 or e865 capsule), bodypack for lavalier or instrument, and rack receiver with various transmitter combinations. The audio signal quality is excellent, with the system’s analogue frequency modulation delivering low latency and natural sound character that avoids the processing artefacts associated with digital wireless systems at this price point. The system handles a wide dynamic range, and the clip LED on transmitters provides clear indication of input overload before distortion occurs in the audio path.

Rack Receiver and System Integration

The EW 100 G4 rack receiver occupies 1U of standard 19-inch rack space and provides balanced XLR and unbalanced jack audio outputs for connection to mixing consoles, cameras, and recording equipment. The large LCD display shows operating frequency, audio level, RF signal strength, and battery status. The receiver can be network-controlled via Sennheiser’s Wireless Systems Manager software for multi-system installations where centralised monitoring and frequency coordination of multiple wireless systems is required.

The Professional Wireless Standard

The Sennheiser EW 100 G4 is available at Pro Audio Video with an authorised Indian warranty. For performers, event sound engineers, video producers, and corporate AV professionals who require reliable, clear, and easily managed wireless audio in a proven and widely-supported platform, the EW 100 G4 remains one of the most trusted choices in professional wireless microphone systems worldwide.
