Sennheiser EW G4 4-Channel Wireless Mic System — A Band

      Sennheiser EW G4 is the evolution wireless system built for every stage, big or small, indoor or outdoor, and it has become the reference choice for musicians, sound designers, broadcasters, and business users alike. At its core is Sennheiser’s most flexible live platform: a true diversity, half-rack receiver in a full-metal housing with an intuitive LCD or OLED display for complete control, paired with reliable transmitters, bodypacks, and handheeds across the 100, 300, 500, and IEM series. Setup stays effortless thanks to fast infrared synchronization between transmitter and receiver, while professional users gain serious headroom with frequency coordination software and advanced multi-channel control. Whether it is a solo performer on a small stage, a multi-channel festival rig, a worship or theater venue, or a film set that needs to capture everything in one take, G4 covers the application without compromise in live sound quality.

The G4 lineup is engineered for scalability. The 100 series delivers up to 42 MHz of bandwidth with 1,680 selectable frequencies, fully tunable in a stable UHF range, supports up to 20 compatible channels, and offers fast frequency allocation by linking up to 12 receivers at once, with a transmission range of up to 100 meters and RF output power of up to 30 mW depending on local regulations. The 500 series takes it further for demanding multi-channel work with up to 88 MHz of bandwidth, 3,520 selectable frequencies, up to 32 compatible channels, and an Ethernet connection for the Wireless Systems Manager (WSM) control software, which makes frequency coordination in large installations straightforward. The IEM series brings the same 42 MHz stability to in-ear monitoring with a stereo transmitter, up to 16 compatible channels, and adjustable RF output of 10, 30, or 50 mW. Across the family, the wide frequency choices and robust UHF performance help keep systems interference-free even in congested RF environments.

On the practical side, G4 is as easy on the road as it is in the installation. Transmitters and bodypacks are sturdy and consistent in the hand, speech-optimized capsule options serve presentation and broadcast duties, and every 100 series set ships with a GA 3 rackmount kit included. Remote control and monitoring through Sennheiser Control Cockpit and WSM keeps business, education, and live users in charge from anywhere in the room, which is why G4 has become the go-to series for universities, conference facilities, and touring applications. The combination of simple operation, professional-grade RF performance, and a broad ecosystem of compatible components makes Sennheiser EW G4 a dependable, future-proof investment for venues, rental companies, and working sound professionals.
