Sennheiser ew IEM G4-Twin Overview

The Sennheiser ew IEM G4-Twin Wireless Monitor System Kit is part of the evolution family of wireless monitoring systems and includes an SR IEM G4 transmitter, two EK IEM G4 stereo receivers, two pair of IE 4 earphones, a rod antenna, GA 3 rackmount kit, and four AA batteries. This kit can be used as a rugged, all-in-one, two-person wireless in-ear monitoring system for live stage, theater, and house-of-worship applications. The system provides up to 1680 frequencies tunable in 25 kHz steps to deliver clear, audio without interference and dropouts. Additional transmitters and receivers can be added for up to 16 wireless IEM channels.

Please note: Although this set comes with two receivers, the transmitter will send on only one frequency at a time, and both receivers will operate on that same frequency.

  • Up to 42 MHz bandwidth with 822 selectable frequencies, fully tunable in stable UHF range
  • Transmission range: up to 300′
  • High RF output power (up to 30mW) depending on country regulations

SR IEM G4 Stereo Transmitter

  • The half-rack, stereo transmitter’s menu-driven backlit OLED display shows current frequency, frequency bank and channel number, metering of AF level, transmission status, equalizer settings, lock status, and input sensitivity. An auto-lock feature is provided to prevent settings from being accidentally altered.
  • Additionally, associated receivers can be synchronized with the transmitter via an integrated infrared interface. This transmitter is built with two electronically balanced XLR-1/4″ combo sockets, a 1/4″ headphone output with headphone volume control, an Ethernet port (RJ45 for remote network-based monitoring), and a 50-ohm BNC-type antenna input. Finally, it has a rugged metal housing and includes a 12V power supply and a GA 3 rackmount kit.

Two EK IEM G4 Stereo Bodypack Receivers with IE 4 Earphones

  • Each bodypack receiver’s menu-driven backlit display shows current frequency, frequency bank and channel number, metering of RF level, metering of AF level, lock status, and battery status. An auto-lock feature is provided to prevent settings from being accidentally altered.
  • In addition, each of the two receivers includes a switchable high-boost and a multi-level limiter. The limiter is adjustable from -18 to -6 dB in 6 dB steps, or it can be bypassed (off). Built in a rugged metal housing, the unit is powered by two 1.5V AA sized batteries or by a Sennheiser BA 2015 rechargeable accupack. The earphone output uses a 3.5mm stereo jack socket.
  • The two pair of IE 4 earbuds deliver outstanding sound quality and feature exchangeable eartips, so you can customize the fit to ensure high isolation from outside noise and an excellent bass response.
