Sennheiser XSW 1-ME2-A Wireless lavalier set. Includes (1) EM XSW 1, (1) SK XSW, (1) ME 2-II lavalier microphone (omnidirectional, condenser) and (1) NT 12-5 CW, frequency range: A (548 - 572 MHz) - 506980

Product Overview

The Sennheiser XSW 1-ME2-A is an entry-level analog UHF wireless lavalier set for presenters, instructors, and broadcast talent who need a discreet clip-on microphone without a wired cable run. The set pairs the EM XSW 1 tabletop receiver with the SK XSW-A bodypack transmitter and the ME 2-II omnidirectional electret condenser lavalier microphone. Operating in the A frequency range (548–572 MHz), it supports up to 10 simultaneously compatible channels with antenna-switching diversity. At $379, it is a complete out-of-box solution for lapel microphone wireless in small to mid-size venues.

Product Description

The XSW 1-ME2-A provides a proven lavalier wireless solution for conference rooms, lecture halls, houses of worship, and corporate AV environments where presenters need freedom of movement and a low-profile microphone presence. The ME 2-II is an omnidirectional electret condenser lavalier that clips to a lapel, collar, or tie and captures natural speech with even sensitivity from all directions, making it tolerant of head movement and less prone to off-axis dropout than directional capsules in a presenter context. The SK XSW-A bodypack transmitter has a dedicated microphone input compatible with the ME 2-II's 3.5 mm locking connector, ensuring a secure physical and electrical connection during active movement. Infrared remote channel synchronization between the SK XSW-A and the EM XSW 1 receiver allows fast, one-press frequency pairing without manual RF menu navigation. The EM XSW 1 receiver uses antenna-switching diversity with integrated antennas, selecting the stronger signal path to reduce dropouts in typical single-room installations. Up to 10 channels can be coordinated simultaneously within the A frequency band, allowing this lavalier set to share a channel pool with other XSW 1 vocal or instrument sets in multi-mic environments. The receiver's front-panel display shows RF level, AF level, and battery status. The NT 12-5 CW power supply is included for AC connection. The XSW 1-ME2-A is the correct choice when a non-directional, low-profile lapel solution is preferred over a headworn microphone.

Frequently Asked Questions

Why use an omnidirectional lavalier instead of a directional one?

Omnidirectional lavaliers like the ME 2-II capture sound from all directions equally, which makes them less sensitive to microphone placement on the presenter's clothing and tolerant of head movement. They also have a more natural, open sound for speech. The trade-off is slightly less feedback rejection compared to a directional capsule, so monitor levels should be set conservatively.

Can the ME 2-II be used with other Sennheiser wireless systems?

The ME 2-II uses a 3.5 mm locking miniature connector compatible with Sennheiser bodypack transmitters across multiple product lines, including XSW, EW, and EW-D series. Confirm the specific connector compatibility for each system before mixing components.

How many XSW 1-ME2-A systems can operate simultaneously?

Up to 10 XSW 1-series channels can be coordinated simultaneously within the A frequency range. The actual usable number depends on local RF conditions and other wireless systems in the same venue.

What is the difference between the XSW 1-ME2-A and the XSW 1-ME3-A?

The XSW 1-ME2-A uses the ME 2-II omnidirectional lavalier, which clips to the chest or lapel. The XSW 1-ME3-A uses the ME 3-II cardioid condenser headworn microphone, which mounts around the ear for a more consistent microphone-to-mouth distance and improved feedback rejection. The headworn mic is preferred for high-SPL environments; the lavalier is preferred for on-camera or low-profile applications.

Is the XSW 1-ME2-A appropriate for outdoor use?

The ME 2-II lavalier can be used outdoors with appropriate windscreens, but the EM XSW 1 receiver is designed for indoor installation. Outdoor deployments with the receiver placed outside would require environmental protection.
