The Sennheiser EW 100 G4-Ci1 Wireless Microphone System Kitis an easy-to-set-up rackmount wireless system that brings reliable high-quality, wireless sound to guitar and bass players performing in small to medium-sized venues including concert stages, houses-of-worship, theaters, and clubs.

The EW 100 G4-Ci1 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. The onboard guitar tuner is an added convenience for musicians.

This system includes a Ci 1 cable that connects your instrument to the lightweight bodypack transmitter. The 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 channels can operate simultaneously in the same space, with the receivers linked together for fast, multi-channel frequency setup.

The EW 100 G4-Ci1 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 4' long Ci 1 cable connects the 1/4" output of your guitar or bass to the bodypack transmitter's locking 3.5mm input.

The adjustable input sensitivity on the transmitter accommodates instruments with passive and active electronics, 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 also offers an adjustable output level range of 48 dB to match the audio input of your mixing board or PA system. 

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 discrete ME 2-II and MKE 2 lavalier mics provide exceptional clarity in spoken word applications.
• 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.

Q: 5. When using the plug-on combo, does that make you have to choose between using the receiver with the plug on or the lav mic? So if I wanted to use both at the same time, would it mean that I need to purchase a second receiver?

A: Yes, the Sennheiser EW 100 ENG G4 Camera-Mount Wireless Combo Microphone System gives you the option of using either the bodypack transmitter or the plug-on transmitter with the receiver. You would need to purchase a second receiver on the same frequency band to be able to use both transmitters at the same time.

Q: 6. 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.
