The Sennheiser EW 100 G4-ME3 is an easy-to-set-up rackmount wireless headset microphone system that brings high-quality, reliable audio to presenters, clergy, lecturers, and performers working in business and educational settings, houses-of-worship, theaters, or on musical stages.

The EW 100 G4-ME3 features a true diversity, half-rack receiver housed in a rugged, full-metal chassis. The receiver's auto-scan function searches a wide 46 MHz UHF tuning range with 1840 selectable frequencies available, seeking out a clean, interference-free channel for your audio transmission.

This system comes with an ME 3-II cardioid headset microphone, which is comfortable to wear and optimized for speech intelligibility. The bodypack transmitter provides up to 8 hours of operation on two AA batteries, with a fixed 30mW RF power output and a transmission range up to 330'. Up to 12 wireless mics can operate simultaneously in the same space, with the receivers linked together for fast, multi-channel frequency setup.

The EW 100 G4-ME3 is backward-compatible with previous evolution systems. You can mix and match G4/G3/G2/G1 receivers or bodypack, handheld, and plug-on transmitters. It is also compatible with EW 300/500 systems.

Headset Mic and Bodypack Transmitter for Hands-Free Presentations

The ME 3-II headset microphone features a directional cardioid polar pattern that helps to reject unwanted feedback sound, making it ideal in environments with loud sound reinforcement.

The headset plugs into the locking 3.5mm connection on the compact SK 100 G4 bodypack transmitter. The adjustable input sensitivity on the transmitter accommodates mic levels ranging from booming voices to quiet speech, and even line-level audio.

The rugged, all-metal transmitter features a programmable mute function and can be locked out to prevent accidental changes during a performance. A backlit LCD displays essential information and provides fast menu access. The transmitter syncs to the receiver via infrared with a quick press on the Sync button.

The SK 100 G4 is powered via two AA batteries or a rechargeable BA 2015 Accupack battery (available separately). Side contacts allow for recharging the Accupack without removing it from the transmitter—requires the L 2015 quick-charging unit (available separately).

Easy-to-Operate Receiver with True-Diversity Reception

The robust, metal EM 100 receiver offers a high-contrast, black and white LCD. The display uses a streamlined menu system with a dedicated Escape button for quick menu navigation and shows battery status of the associated transmitter.

The system features 20 fixed frequency banks with up to 12 compatible frequency presets and 1 user bank with up to 12 user-programmable frequencies.

To prevent interference, the EM 100 receiver's true-diversity reception compares incoming signals on two independent receiver circuits to ensure optimal RF quality. To ensure crystal clear audio, Sennheiser's proprietary HDX compander technology maximizes the microphone's signal-to-noise ratio, while avoiding RF noise.

The built-in equalizer enables you to change the frequency response of the output signal; you can reduce the bass range and boost the treble range. The receiver also offers an adjustable output level range of 48 dB to match the audio input of your mixing board or PA system. Musicians will appreciate the built-in guitar tuner.

The back panel houses a balanced XLR output as well as an unbalanced 1/4" output. A kit is included for rackmount installation. The unit comes with a universal power supply and EU, US, UK, Korea, Australia, and China adapters.

Fast Multi-Channel Setup for Expanded System

To simplify and speed up your workflow, two RJ10 data networking ports allow you to daisy-chain up to 12 receivers and quickly perform a frequency setup for the entire multi-channel system via the Easy Setup function.

If you assign the frequencies manually, you can expand the setup to accommodate a maximum of 20 receivers. An RJ10 cable is included.

Enhance the Performance of Your System

The detachable antennas with BNC sockets allow you to create a larger system using up to four EM 100 receivers connected to a single pair of remote antennas. This setup requires the ASA 214 active antenna splitter (available separately).

Adding a pair of A 1031-U omnidirectional antennas or a pair of A 2003 UHF directional antennas increases the range of your system and offers increased protection against interference.

Add Functionality to Your System

Sennheiser offers a variety of lavalier, headset, and handheld microphone options to adapt your EW system as your needs evolve.

  • The discrete ME 2-II and MKE 2 lavalier mics provide exceptional clarity in spoken word applications.
  • The SKM 100 handheld transmitter is available with three different mic capsule options for presenters and performers who prefer the flexibility of a handheld microphone.
  • The Ci 1 instrument cable lets you connect the bodypack transmitter to a guitar or bass.

Sennheiser EW 100 G4-ME3 Reviews

Prone to EMF

By David
Rated 3 out of 5
Date: 2019-05-08

I recently wrote a five star review but have used this system for a couple of months now and have found it picks up a lot of EMF noise from digital devices close to it. I have it in a rack directly under a Behringer Feedback exterminator. When the FBX is active, it generates a bit of noise that gets induced into the Sennheiser receivers audio section post-RF receiver. This means the receiver (which is digital tone squelched) will show Mute when the systems transmitter is off, but the audio meter will be pegged with noise and the noise goes on to the output of the device so you will hear a bunch of static. The problem goes away when the transmitter is turned on and overpowers the noise, but if the transmitter gets powered off, or signal strength drops out, you will hear the static. I also noticed this problem with Sennheisers previous G3 receivers - in this case, the G3 was sitting beside an active HDMI cable and the same problem - noise induced post-RF section/pre-audio section. Problem goes away once transmitter is active. This is a little annoying. The work-around is an external antenna system plugged into the receiver and placed away from the noise-inducing devices. As an aside, I have an older Audio Technica 3000 series receiver in the same rack next to the G4 directly under the feedback exterminator and no noise is induced in it under any circumstances. So, be forewarned. Buy the G4 system, plan on using external antennas to eliminate audio noise. Otherwise, it is a really nice system, well built and durable. I just hope Sennheiser can figure out this EMF interference problem and fix it.

Rugged, high quality unit

Nice unit.  Very well built, easy to use.  But weve all come to expect that from the upper level Sennheiser stuff anyway.  It is half rack design and I was able to mount it side by side with an older, Audio Technica 3000 series in my rack by only drilling one hole in the connector plate on bottom...fits nicely.  The picture of the headset mic is a little deceiving; the headband looks large and robust, but that wide section youre looking at is just a thin cloth band that does not conform to the molded wire frame assembly like it looks in the picture.  I think they must have put a lot of starch in it to hold that shape for the product photo.  With that said, the headset is still of decent quality overall and I like the fact that it uses a condenser mic instead of dynamic.  I choose this particular headset because I provide wireless for events that have younger children and the fancier, more expensive ear hanging headset mics do not stay on those tiny ears and heads all that well.  This is a little bulkier but will hold on where the other, sleeker models will fall off.  I like everything about the display on both the transmitter and receiver.  Dont misunderstand me; I like the Audio Technica UHF stuff that is available at this price point.  The Sennheiser electronics and features are literally apples to apples the same as the comparable model Audio Technica, but about $20.00 more for the Sennheiser.  For that extra $20 you get a condenser headset mic (the A/T is dynamic) and a little more robust headset.   Im not walking away wishing I could have had...  This is exactly the headset wireless I wanted.
