Sennheiser EW IEM G4 – Wireless In-Ear Monitor System

Product Overview

The Sennheiser EW IEM G4 is a complete wireless in-ear monitor system for professional live sound, giving a single performer a reliable stereo monitor mix on stage. Built on the proven evolution wireless G4 platform, this UHF in-ear monitoring system pairs a half-rack stereo transmitter with a rugged bodypack receiver and IE 4 earphones. With up to 42 MHz of switching bandwidth and up to 16 compatible channels, it scales cleanly for houses of worship, auditoriums, and touring productions. Available in A (516–558 MHz), A1 (470–516 MHz), and G (566–608 MHz) frequency bands.

Product Description

The EW IEM G4 set includes the SR IEM G4 stereo transmitter, the EK IEM G4 stereo bodypack receiver, IE 4 earphones, a rod antenna, and a GA 3 rackmount kit for immediate rack installation. The transmitter's full-metal housing and backlit OLED display give engineers direct control over frequency, RF power, and audio metering, while infrared sync lets the transmitter configure the receiver in seconds. Compatibility with Sennheiser's Wireless Systems Manager (WSM) software supports coordinated frequency allocation across larger multi-channel deployments.

The system tunes across a stable UHF range with up to 1,680 selectable frequencies in 25 kHz steps, and the Sennheiser HDX compander delivers clear, low-noise audio across the full spectrum. Switchable RF output power (10/30/50 mW, subject to regional regulations) and a transmission range of up to 100 m / 300 ft provide flexibility for stages of any size. The bodypack adds a switchable high-boost and adjustable limiter to protect performers' hearing. For multi-performer rigs, expand RF distribution with the AC 3200-II antenna combiner and a A 5000-CP directional antenna. See more in our Sennheiser collection.
