Sennheiser XSW 1-835-A Wireless vocal set. Includes (1) EM XSW 1, (1) SKM 835 XSW (cardioid, dynamic) (1) NT 12-5 CW and (1) MZQ 1 clip, frequency range: A (548 - 572 MHz)

Product Overview

The Sennheiser XSW 1-835-A is an entry-level analog UHF wireless vocal set for singers, presenters, and AV integrators who need a straightforward single-channel system without complex RF configuration. The set pairs the EM XSW 1 tabletop receiver with the SKM 835-XSW handheld transmitter, which uses the proven e835 cardioid dynamic capsule. Operating in the A frequency range (548–572 MHz), it delivers up to 10 simultaneously compatible channels with antenna-switching diversity for reliable signal in standard venue environments. Everything needed for immediate deployment is included: receiver, handheld transmitter, NT 12-5 CW power supply, and MZQ 1 mic clip.

Product Description

The XSW 1-835-A is designed for installations and live events where simplicity, speed of setup, and proven vocal sound are the priorities. The EM XSW 1 receiver integrates its antennas directly into the chassis, eliminating external antenna cables for standard counter or tabletop placement. Antenna-switching diversity monitors both antennas and selects the stronger signal path, reducing dropouts in typical single-room RF environments. Infrared remote channel synchronization allows the receiver to program the SKM 835-XSW transmitter frequency with a single button press, avoiding manual RF menu navigation during setup. The SKM 835-XSW handheld transmitter carries the e835 cardioid dynamic capsule, which provides consistent directional pickup, strong rejection of stage monitors, and a natural vocal character suited to speech and amplified singing. The UHF A band (548–572 MHz) provides a stable spectrum allocation for professional wireless in many markets. Up to 10 XSW 1 channels can be coordinated simultaneously within the available bandwidth, making this set expandable for multi-microphone installations. The receiver's front-panel display shows RF level, AF level, and battery status at a glance. The NT 12-5 CW power supply connects the receiver to standard AC power, and the MZQ 1 clip allows stand mounting of the handheld transmitter when not in use. The XSW 1-835-A is the recommended starting point for small venues, corporate AV, and houses of worship deploying their first UHF wireless vocal system.

Frequently Asked Questions

What is the difference between the XSW 1 and XSW 2?

The XSW 2 uses true diversity reception with two independent RF paths and external antennas, which provides more reliable signal in demanding RF environments with multipath interference. The XSW 1 uses antenna-switching diversity with integrated antennas, which is appropriate for smaller venues and less complex RF conditions. The XSW 2 also offers 960 selectable frequencies versus 10 on the XSW 1.

How many XSW 1-835-A systems can run simultaneously?

Up to 10 channels can operate simultaneously within the A frequency range (548–572 MHz). The usable number in any specific venue depends on local RF conditions and any other wireless systems operating nearby.

Does the receiver require external antennas?

No. The EM XSW 1 has integrated antennas for standard tabletop deployment. External antenna distribution is not required for typical single-room installations.

What microphone capsule is in the SKM 835-XSW?

The SKM 835-XSW uses an e835-class cardioid dynamic capsule, the same capsule design used in Sennheiser's wired e835 vocal microphone, known for its consistent directional pickup and feedback rejection on live stages.

Is the XSW 1-835-A compatible with other XSW 1 sets?

Yes. All XSW 1-series sets in the same frequency range (A) share channel coordination, allowing vocal and instrument sets to be used simultaneously within the same 10-channel pool.
