Operating in the A band (516–558 MHz) with 1680 selectable frequencies and true diversity reception, it provides a reliable wireless instrument solution for live performance and professional AV installation. At $679, it is Sennheiser's mid-tier professional wireless instrument platform for demanding venues and touring applications.

Product Description

The EW 100 G4-CI1 represents a significant step up from the XSW platform in RF performance, frequency agility, and build quality. The EM 100 G4 receiver uses true diversity reception with two independent RF circuits and external antennas, providing robust signal performance in larger venues, outdoor stages, and environments with complex RF interference. With 1680 selectable frequencies across the A band, the system offers comprehensive frequency coordination capability for dense multi-channel deployments alongside other G4-series systems. The SK 100 G4 bodypack transmitter has a rugged metal housing, a 3.5 mm locking microphone input and a switchable 6.3 mm instrument input via the CI 1 cable, allowing it to serve both instrument and microphone wireless functions across the same platform. The EM 100 G4 receiver features an intuitive front panel with graphical display, RF and AF metering, and transmitter battery status monitoring. Auto scan and infrared sync allow rapid frequency coordination during setup. The SK 100 G4's high-headroom input handles the wide dynamic range of passive and active guitar pickups. The EW 100 G4-CI1 is appropriate for professional guitarists and bassists, touring musicians, houses of worship with multiple instrument channels, and AV system integrators building permanent professional wireless installations where the increased frequency density and build quality of the G4 platform are required over the XSW product line.

Frequently Asked Questions

How does the EW 100 G4-CI1 compare to the XSW 2-CI1-A?

The EW 100 G4 offers 1680 selectable frequencies versus the XSW 2's 960, a more advanced graphical display with auto-scan, a more rugged metal transmitter housing, and higher build quality throughout. It is the appropriate choice for professional touring and installation scenarios where the XSW 2's capabilities are a limiting factor.

Can the SK 100 G4 bodypack also be used with microphones?

Yes. The SK 100 G4 has a 3.5 mm locking microphone input in addition to the CI 1 instrument input, making the same bodypack usable across instrument and microphone wireless applications within the EW 100 G4 platform.

Is the EW 100 G4-CI1 compatible with EW 300 G4 or EW 500 G4 receivers?

The SK 100 G4 bodypack transmitter operates on the same frequencies as EW 300 G4 and EW 500 G4 receivers in the same frequency band. Confirm frequency band and compatibility for the specific receiver model before cross-pairing components.

How many EW 100 G4 systems can operate simultaneously?

With 1680 selectable frequencies, the EW 100 G4 supports a substantially higher number of simultaneous channels than the XSW platform. The exact number depends on frequency coordination planning, local RF conditions, and other wireless systems in the same venue.

Does the auto scan function automatically avoid local RF interference?

Yes. The EM 100 G4 receiver's auto scan function analyzes the available spectrum and identifies clear frequencies within the A band, selecting the best available channels for use and avoiding occupied frequencies from local RF sources and other wireless systems.
