Sennheiser XSW 2-CI1-A Wireless instrument set. Includes (1) EM XSW 2, (1) SK XSW, (1) NT 12-5 CW, (1) CI 1 instrument cable and (1) GA 1 XSW 2, frequency range: A (548 - 572 MHz) - 507136

Product Overview

The Sennheiser XSW 2-CI1-A is a mid-tier analog UHF wireless instrument set that combines the true diversity RF performance of the XSW 2 platform with a standard 6.3 mm instrument cable input for electric guitar, bass, and other line-level instrument sources. The set includes the EM XSW 2-A true diversity receiver, the SK XSW-A bodypack transmitter, the CI 1 instrument cable, and a power supply. Operating in the A frequency range (548–572 MHz) with 960 selectable frequencies, it delivers significantly more reliable RF performance than the XSW 1, making it suitable for professional stage and installation use.

Product Description

The XSW 2-CI1-A provides instrumentalists with a professional-grade wireless solution that addresses the RF shortcomings of entry-level antenna-switching systems. True diversity reception on the EM XSW 2-A uses two independent RF receiver circuits with external antennas, continuously selecting the stronger signal path to eliminate multipath dropouts that can occur in larger stages, outdoor venues, and environments with complex RF interference patterns. With 960 selectable frequencies across the A band, the system can be precisely frequency-coordinated alongside other XSW 2 systems and avoid local RF interference far more flexibly than the 10-channel XSW 1 platform. The SK XSW-A bodypack transmitter connects to instruments via the included CI 1 cable, which terminates in a standard 6.3 mm mono jack compatible with passive and active electric guitars, bass guitars, and electronic keyboards. No additional adapters are required. Infrared sync allows rapid frequency pairing between the receiver and bodypack. External antennas on the EM XSW 2-A can be repositioned or extended with optional cables for venues where the receiver is rack-mounted away from the stage. Front-panel displays on both transmitter and receiver show RF level, AF level, and battery status. The XSW 2-CI1-A is appropriate for professional guitarists and bassists in live performance settings, houses of worship with multiple instruments on stage, and touring acts requiring a reliable compact wireless instrument system.

Frequently Asked Questions

Why choose the XSW 2-CI1-A over the XSW 1-CI1-A?

The XSW 2 uses true diversity reception with two independent RF paths and 960 selectable frequencies, versus the XSW 1's antenna-switching diversity and 10-channel limit. For professional stages, larger venues, outdoor events, or any environment with significant RF interference, the XSW 2 provides substantially better reliability and frequency coordination capability.

What instruments are compatible with the CI 1 cable?

The CI 1 cable has a standard 6.3 mm mono jack, compatible with passive and active electric guitars, bass guitars, and any instrument with a standard instrument output including electronic keyboards.

Can the XSW 2-CI1-A be used alongside vocal sets in the same band?

Yes. All XSW 2-series sets in the A frequency range share the same 960-frequency pool and can be frequency-coordinated together, allowing instrument and vocal sets to operate simultaneously.

Is the SK XSW-A bodypack also used in lavalier and headmic sets?

Yes. The SK XSW-A bodypack is the same transmitter used across the XSW 1 and XSW 2 bodypack sets, including the ME2 lavalier and ME3 headmic configurations. The input is configured with the appropriate cable or connector for each application.

Can external antennas be remoted to improve RF coverage?

Yes. The EM XSW 2-A's external antennas support optional extension cables for remote antenna placement, which is particularly useful in rack-mount installations where the receiver is positioned away from the stage or performance area.
