The Sennheiser EW 100 G4-835-S is an easy-to-set-up rackmount wireless handheld 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 G4-835-S 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 includes an SKM 100 G4-S handheld transmitter equipped with an interchangeable MMD 835 dynamic cardioid microphone capsule optimized for speech. The handheld 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 G4-835-S 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 MMD 835 dynamic capsule features a cardioid polar pattern that minimizes background noise and feedback.

The rugged, all-metal handheld transmitter features a 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 SKM 100 G4-S is powered via two AA batteries or a rechargeable BA 2015 Accupack battery (available separately). An LA 2 charging adapter (available separately) allows for recharging the Accupack without removing it from the transmitter—requires the L 2015 quick-charging unit (available separately).

The transmitter's interchangeable capsule design allows you to use a variety of optional dynamic and condenser mic capsules, with pickup patterns ranging from wide omnidirectional to narrow supercardioid —capsules include the MMD 835, MMD 845, MME 865, MMD 935, MMD 945, and MMD 42.

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.

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 bodypack transmitter with variety of lavalier and headset 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 lightweight ME 3-II is a comfortable, durable headset microphone for active presentations.
• The Ci 1 instrument cable lets you connect the bodypack transmitter to a guitar or bass.

Related Questions and Answers

Q: 1. Do the receivers rotate? I have a Canon XA30 I'm looking to use with two mics at the same time, and the two mic inputs are side by side. How will two receivers hook up at the same time?

A: The Sennheiser AVX receivers do rotate on the XLR jack almost a full rotation. You can easily connect both receivers to the mic inputs on the XA30 or similar camera.

Q: 2. I'm shooting with a 16mm camera so won't be able to phantom power the receiver. Can I power it w/ an external battery instead?

A: You could use a portable phantom power supply such as the Mackie M48 Single-Channel 48V Phantom Power Supply (B&H # MAM48) or the Xvive Audio P1 Portable Phantom Power Supply with Rechargeable Battery (B&H # XVP1) to power the Sennheiser AVX EKP Camera-Mount Digital Plug-In Receiver included with the Sennheiser AVX-Combo SET Digital Camera-Mount Wireless Microphone System.

Q: 3. Can I use my own Cos-11 mic with this transmitter?

A: If your COS-11 is wired properly for Sennheiser EW Evolution Wireless, yes you can. If not, and if you're not equipped to wire it yourself, B&H sells a COS-11 Pre-Wired for Sennheiser. Item# SAC11WNSETRB

Q: 4. Anyone have experience mounting two receivers side-by-side on an EVA1? Want to make sure they would fit before purchasing the dual kit…

A: Yes this 3 shoe extension. Goes on the camera shoe and then you can mount both receivers onto 2 of the 3 shoes. BH #VECB465 you can find it on the B&H website.

Q: 5. Is this set compatible with Roland BA330 PA system?

A: Yes

Q: 6. If I want 4 lavs across two cameras, will buying these work or will I get some feedback?

A: The Sennheiser AVX series wireless microphone systems are single-channel so only one transmitter can be used with each receiver. The Sennheiser AVX 2-Person Digital Camera-Mount Wireless Combo Microphone System with Case Kit will allow you to mic two people and both receivers can be connected to the same camera. In order to mic four people at the same time using the AVX systems, you will need to have four individual AVX systems (or two of the AVX 2-Person Kits). So you can use two of the AVX 2-Person Kits with your two cameras. Up to eight of the AVX systems can be used simultaneously within a 98-foot range. Interference and feedback would not be a problem.

Q: 7. How well suited is this for live events, such as a ballroom with a presentational speaker? Will lots of people in the room interfere with the signal if the tech table is in the back? Will the automatic gain control affect the person trying to bring the voice up on the board?

A: The AVX system is very good, but it has a short operating range of up to 98 feet (line of sight) and you may experience problems with signal dropout if the receiver is too far from the transmitter or if anything blocks the signal path between the transmitter and receiver. If you want to have the same flexibility as the AVX combo system to be able to switch between lavalier and handheld mics, you may like the ew 100 G4 combo system which includes the ew 112P wireless lavalier system combined with an SK 100 plug-on transmitter that will attach to any dynamic mic with an XLR output connector, allowing you to select your own handheld mic. If you prefer the Sennheiser wireless handheld mic, you can purchase an SKM 100 G4 Handheld Wireless Microphone Transmitter with No Mic Capsule (B&H # SESKM100G4A1) with a Sennheiser MMD 835 Cardioid Dynamic Capsule (B&H # SEMMD835) and combine it with an ew 112P G4 lavalier system (B&H # SEEW112PG4A1). Please contact us if you would like further assistance.

Q: 8. Is there a way to listen to the audio while simultaneously recording with the XLR adaptor?

A: Headphones from your camera.

Q: 9. It should be noted, that while this system includes 2 transmitters, only 1 can be used at a time. -- Does this mean I can't use two lavs at the same time, or one lav and one handheld during a shoot?

A: The transmitters work independently. You can use two of the mics at the same time in any combination, so long as you can accept two lines of audio into the device you are using.

Q: 10. Does this kit comply with the current FCC spec for wireless transmission?

A: Yes, the Sennheiser AVX-Combo SET Digital Camera-Mount Wireless Microphone System is legal for use within the USA without an FCC license. It operates on the 1.9 GHz band.
