The Sennheiser EW 100 G4-ME4 is an easy-to-set-up rackmount wireless lavalier 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-ME4 features a true diversity, half-rack receiver housed in a rugged, full-metal chassis. The receiver'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.

This system comes with an ME 4 cardioid lavalier microphone optimized for speech intelligibility in loud environments. 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-ME4 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.

The ME 4 lavalier microphone features a directional cardioid polar pattern that helps to reject unwanted background sound, making it ideal in environments with loud sound reinforcement.

The lav 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).

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 offers an adjustable output 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.

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.

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.

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

• The lightweight ME 3-II headset mic provides 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.

Q: 1. Will the plug-on wireless transmitter attach properly to a side-exit XLR boom pole (particularly K-Tek Avalon), or will it not attach firmly enough, please? Would it be necessary to buy something like a K-Tek KlassicPro upgraded to their KPTA plug-on TX adapter? Is there another brand/model of boom pole that would suit the Sennheiser plug-on TX?

A: The SKP 100 G4 Plug-On Transmitter within the Sennheiser EW 100 ENG G4 Camera-Mount Wireless Combo Microphone System may not attach firmly to a side-exit XLR connection on a boompole. The transmitter features a fastening collar to tighten however it is uncertain whether this is sufficient to prevent the connection from loosening. The KPTA Sidekick Plug-On may help in that it keeps the transmitter in a more ideal orientation.

Q: 2. Does this come with an XLR cable?

A: They Sennheiser ew 512P G4 system comes with the CL500 receiver 3,5mm male to XLR male receiver output cable (B&H # SECL500), which connects the wireless system to a professional camera, recorder, mixer, etc. An additional CL1 3.5mm male to 3.5mm male receiver output cable (B&H # SECL1) is also included for connection to DSLR cameras and other devices with a 3.5mm input jack.

Q: 3. has anyone use Sennheiser EW 112P G4 to send line level audio from a computer audio out to a mixer board line level in stereo i know i will need a 3.5 to 3.5 mm for the transmitter and 3.5 to RCA for the mixer board line in?

A: While the Sennheiser EW112PG4 can be used to transmit line level audio wirelessly, it will only send a single channel of audio. You can mono sum the output of the computer using this device, BH #RALTIBLOX , use the BH# SECL2 cable for xlr into the transmitter, and go single XLR out into the mixer. If you need stereo sends, you would need two transmitters and two receivers for the 2 channels of audio. Here a system, more designed for stereo transmission, BH #ALSTEALTHWRL.

Q: 8. Would this lavalier mic work in europe? italy?

A: The wireless systems that are sold by B&H are intended for use in North America without a license. The FCC regulations vary in different countries, so a license may be required. The A1: 470 to 516 MHz, A: 516 to 558 MHz, and G: 566 to 608 MHz frequency bands for the Sennheiser EW 112P G4 Camera-Mount Wireless Omni Lavalier Microphone System are all able to be used in Italy, however, a license is required. As additional options for a Sennheiser wireless system that you can use in Italy without a license, you may want to consider the Sennheiser AVX-ME2 SET Digital Camera-Mount Wireless Omni Lavalier Microphone System (B&H #SEAVXME2SET4) or the Sennheiser XSW-D LAVALIER SET Digital Wireless Omni Lavalier Microphone System (B&H # SEWXSLSTR). The AVX system operates on the 1.9 GHz frequency band and includes a plug-in receiver which can be connected to a 3.5mm mic input using the included XLR to 3.5mm cable. The XSW-D system operates on the 2.4 GHz frequency band and can also be used with an XLR female to 3.5mm cable to connect to a 3.5mm mic input. Both systems include the Sennheiser ME 2 II Lavalier Microphone, which is the same microphone that is included with the EW 112P G4 system.

Q: 9. Can I get a shotgun mic in this kit instead of the handheld?

A: The plug-on transmitter is designed to be used with dynamic microphones only, and will not work with a shotgun mic, which are condenser mics. The SKP500 will work with shotgun mics, but is not available in this kit configuration: https://www.bhphotovideo.com/c/product/1385730-REG/sennheiser_skp_500_g4_gw1_skp_500_g4_pro.html

Q: 10. I've read that the AVX series introduces a 19 ms delay. Does this system introduce any delay? I will sometimes want to run wireless and wired microphones at the same time.

A: Hi Dave - the evolution Wireless series is an analog wireless system that operates on UHF frequencies - there's no delay with respect to transmission time. However, the distance of your wired microphone capsule from your wireless lav capsule should also be taken into consideration - due to timing differences between direct audio and distant audio, you can get a phasing sound, making your audio a bit hollow or lacking body. The AVX system operates on a DECT Wireless standard, which has 19ms of delay - we generally recommend to not mix G4 and AVX wireless together for that reason.
