Sennheiser XSW 1-CI1-A Wireless Instrument set. Includes (1) EM XSW 1, (1) SK XSW, (1) NT 12-5 CW, and (1) CI 1 instrument cable, frequency range: A (548 - 572 MHz) - 506994

Product Overview

The Sennheiser XSW 1-CI1-A is an entry-level analog UHF wireless instrument set for electric guitar, bass guitar, and other line-level or passive instrument sources. The set includes the EM XSW 1 tabletop receiver, the SK XSW-A bodypack transmitter, the CI 1 instrument cable, and a power supply — everything needed to go wireless from a standard 6.3 mm instrument output. Operating in the A frequency range (548–572 MHz), it supports up to 10 simultaneously compatible channels with antenna-switching diversity reception.

Product Description

The XSW 1-CI1-A delivers reliable UHF wireless performance for instrumentalists who need freedom of movement on stage without compromising signal integrity. The SK XSW-A bodypack transmitter accepts instrument signals via the included CI 1 cable, which terminates in a standard 6.3 mm mono jack on one end and connects to the bodypack's locking input on the other. This makes the set compatible with passive and active electric guitars, bass guitars, and electronic keyboards without any adapters. The EM XSW 1 receiver uses antenna-switching diversity with integrated antennas, selecting the stronger of two antenna signals to reduce dropouts in typical single-room environments. Infrared remote sync allows the receiver to program the SK XSW-A transmitter's channel with a single button press, eliminating manual frequency entry during setup. The UHF A band (548–572 MHz) provides a stable professional spectrum allocation, and up to 10 channels can be coordinated simultaneously, allowing this instrument set to share a frequency pool with XSW 1 vocal sets in band or ensemble deployments. The receiver's front-panel display shows RF level, AF level, and battery status. The NT 12-5 CW power supply is included for standard AC connection. The XSW 1-CI1-A is appropriate for small venues, houses of worship, school productions, and corporate event stages where a simple, compact wireless instrument solution is required.

Frequently Asked Questions

What instruments are compatible with the CI 1 cable?

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

Can this set be used alongside XSW 1 vocal sets?

Yes. All XSW 1-series sets in the A frequency range share the same 10-channel coordination pool. An instrument set and one or more vocal sets can operate simultaneously within that pool.

Does the SK XSW-A bodypack support microphone inputs?

The SK XSW-A accepts both mic/line and instrument inputs. In this set it is configured with the CI 1 instrument cable, but the same bodypack is used in the XSW 1-ME2-A and XSW 1-ME3-A lavalier and headmic sets with the appropriate microphone capsule.

Is the XSW 1 receiver rack-mountable?

The EM XSW 1 is a tabletop unit and is not designed for standard 19-inch rack mounting without an optional rack kit. For rack deployments, the EM-XSW 2-A true diversity receiver with external antennas is a more suitable choice.

How is the transmitter frequency synchronized to the receiver?

Point the SK XSW-A bodypack at the EM XSW 1 receiver's IR sensor and press the sync button on the receiver. The receiver transmits the channel frequency to the bodypack via infrared, completing setup without manual frequency entry.
