The complete set includes a pocket transmitter, a stationary True-Diversity receiver, and the matching Ci1 guitar cable.

A wired connection can quickly become a limitation on stage. It limits your range of motion, can get caught between stands, and makes dynamic performances more difficult. With the Sennheiser XSW 2-Ci1, you can move much more freely while the instrument signal is transmitted analog via the UHF frequency band. The A-band frequency range used extends from 548 to 572 MHz.

The system is designed specifically for guitarists, bassists, and other musicians who use instruments with a suitable jack output. The included Ci1 guitar cable connects the instrument to the SK-XSW bodypack transmitter. The EM-XSW2 receiver picks up the radio signal and transmits the audio signal to the downstream audio device via an XLR or jack output.

With a switching bandwidth of 24 MHz, eight frequency banks (each with twelve channels), and a total of 96 selectable frequencies, the system can be adapted to a variety of performance environments. The built-in scan function helps you find available frequencies. This is particularly helpful when other wireless systems are already in use at a venue or when the existing wireless environment is not fully known prior to the performance.

The stationary receiver is housed in a rugged metal enclosure and comes with a rack kit. This makes the Sennheiser XSW 2-Ci1 A-Band Instrument suitable for both portable standalone use and installation in a compatible rack. A carrying case, the required power supply, and two AA batteries for the transmitter are also included. You thus receive a largely fully equipped set that can be put into operation without extensive additional components.

A sturdy receiver is therefore not only visually appealing but can also be an advantage in the demanding day-to-day reality of live events.

Analog UHF transmission is ideal for musicians who prefer a classic wireless system with straightforward operation. The instrument signal is transmitted from the bodypack transmitter to the receiver with a transmission power of 10 mW. The specified audio frequency range of 50 to 16,000 Hz is optimized for the transmission of typical instrument signals.

Technical Details of the Sennheiser XSW 2-Ci1 A-Band Instrument System

Analog UHF Transmission in the A-Band

The Sennheiser XSW 2-Ci1 A-Band Instrument 548–572 MHz, True-Diversity UHF Wireless System uses analog transmission technology. The frequency range extends from 548 to 572 MHz, covering a total switching bandwidth of 24 MHz. Within this range, eight frequency banks are available, each with twelve channels.

A total of 96 frequencies can be selected. This selection makes it easier to adapt to local radio conditions and to other wireless systems at the event venue. Before each use, you should check which frequencies are permitted and available at the respective location. Radio frequencies may be regulated differently by region and may overlap with other applications.

The integrated frequency search feature assists with system setup. Using the scan function, the receiver can search for available frequencies. This eliminates the need to assess the radio environment exclusively by hand. This saves time and facilitates a structured setup, especially at changing event locations.

True-diversity receiver for stable signal reception

The EM-XSW2 is designed as a true-diversity receiver. In such a system, two reception paths—or antenna signals—are evaluated. The receiver can use whichever signal path is stronger at any given time, thereby reducing the risk of brief reception dropouts.

Radio waves can be reflected in rooms and on stages. Depending on the transmitter’s position, this can result in areas with stronger or weaker reception. Since musicians move around during a performance, reception conditions can change constantly. Diversity technology helps compensate for these changes and maintain the most stable signal path possible.

The receiver features external BNC antennas. The antennas can be removed and replaced as needed or repositioned within a professional setup. The package includes the antennas required for regular operation of the system.

SK-XSW Bodypack Transmitter with 10 mW Transmit Power

The compact SK-XSW bodypack transmitter is attached to a guitar strap, clothing, or a suitable bag. It connects to the instrument via the included Ci1 guitar cable. The transmission power is 10 mW and is optimized for use with the stationary receiver.

The transmitter is powered by two AA batteries. Two compatible batteries are included in the set, so you can test and use the wireless system immediately after setup. There is no built-in rechargeable battery or separate charging system. For longer events, it is therefore recommended to have additional AA batteries on hand.

A battery level indicator shows the status of the batteries in use. This allows you to check the battery level before your performance and replace the batteries in a timely manner if necessary. This reduces the risk of the transmitter’s power supply unexpectedly failing during a performance.

Audio frequency range from 50 to 16,000 Hz

The system’s audio frequency range extends from 50 to 16,000 Hz. This allows the Sennheiser XSW 2-Ci1 to transmit typical instrument signals and makes it particularly suitable for electric guitars, electric basses, and other instruments with a compatible output.

The actual sound is not determined solely by the wireless link. The instrument itself, the pickups, the cables used, effects units, amplifiers, and speakers all influence the final sound. The wireless system handles the task of transmitting the signal between the instrument and the downstream audio equipment across the stage without the need for a continuous guitar cable.

For musicians, this means greater freedom of movement. They can move away from the amplifier while playing, take up different positions on stage, or enter the audience area before a performance to assess the overall sound from various vantage points.

XLR and jack outputs for flexible connections

The stationary receiver features both an XLR output and a jack output. This allows the system to be connected to a variety of audio devices. The XLR output, for example, is suitable for connecting to a mixing console, a stage box, or a professional audio system. The jack output can be used, among other things, to connect to a guitar amplifier, effects unit, or other compatible devices.

The output level can be switched between Mic and Line. This feature is important because microphone inputs and line inputs expect different signal levels. By selecting the appropriate setting, you can better match the output signal to the input being used and avoid clipping or a level that is too low.

During setup, you should first check which input is being used on the connected device. Then, set the receiver’s output accordingly. Further fine-tuning is done using the level controls on the mixing console, amplifier, or audio interface.

Adjustable squelch to suppress unwanted signals

The Sennheiser XSW 2-Ci1 features an adjustable squelch. This squelch function determines the minimum signal level at which the receiver enables the audio output. If the transmitter signal is not strong enough, the squelch can suppress unwanted noise or interference.

Setting the squelch too low can cause faint interference to become audible. If the value is set too high, the usable range may be reduced. Therefore, the setting should be adjusted to suit the specific environment. In a low-interference environment, a moderate setting is often sufficient, while in more congested radio frequency bands, an adjustment may be necessary.

Rugged stationary receiver with rack kit

The EM-XSW2 receiver measures 200 mm wide, 42 mm high, and 127 mm deep. It weighs approximately 0.7 kg. Thanks to its compact design, the receiver can be placed on an amplifier, a table, or inside a suitable rack.

The included rack kit facilitates integration into a professional transport or stage rack. A secure mounting protects the receiver during transport and ensures a clean setup. Especially for recurring events, a pre-configured rack can reduce setup time, as power and audio connections can sometimes be permanently set up in advance.

The metal housing enhances the receiver’s stability. The controls remain easily accessible, while the external BNC antennas for radio reception can be properly aligned. For a reliable connection, the antennas should not be obstructed by large metal objects and should be positioned with a clear line of sight to the stage area whenever possible.

What’s Included with the Sennheiser XSW 2-Ci1 A-Band Instrument

The set includes an SK-XSW bodypack transmitter and an EM-XSW2 diversity receiver. The bodypack transmitter transmits the signal from the connected instrument, while the receiver picks up the radio signal and sends it to the amplifier or mixing console.

An NT 12-5 CW power supply is included to power the receiver. Two AA batteries power the bodypack transmitter. The included Ci1 guitar cable connects the instrument to the transmitter.

In addition, a rack kit and a carrying case are included. The rack kit allows for stationary or mobile rack mounting of the receiver. The carrying case makes it easy to store and transport all components together. This keeps the transmitter, cables, and accessories in one place and ensures they’re quickly available for your next performance.
