Sennheiser EM 100 G4 Wireless Receiver

Sennheiser EM 100 G4 Overview

The Sennheiser EM 100 G4 is a true-diversity, half-rack wireless receiver housed in a rugged, full-metal chassis and compatible with the SK 100 G4 bodypack transmitter and the SKM 100 G4 handheld transmitter. It offers 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 EM 100 G4 is backward-compatible with all previous evolution systems. You can mix and match G4/G3/G2/G1 bodypack or handheld, and plug-on transmitters. It is also compatible with EW 500 and EW 300 systems.

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 the battery status of the associated transmitter.
The EM 100 G4’s auto-scan function searches a wide 42 MHz UHF tuning range with 1680 selectable frequencies available, seeking out a clean, interference-free channel for your audio transmission. 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 compandor 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 Receiver

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.
