• Sennheiser launches XS Wireless IEM in-ear monitoring system


    Sennheiser launches XS Wireless IEM for musicians seeking to switch from floor wedges to wireless IEMs.

    XS Wireless IEM (or XSW IEM for short) is a complete starter set for personal monitoring and has been reportedly designed to set a new standard for simple, flexible, and reliable wireless in-ear monitoring, by enabling users to quickly establish an easy-to-manage wireless connection in the professional UHF range.

    Aligned and pre-calculated frequency presets helps get musicians started. If desired, transmission frequencies can also be selected manually.

    Backlit displays on both the receiver bodypack and the rack-mount transmitter reportedly help to clearly see settings even in poor lighting conditions. In addition, the system offers a limiter to protect user’s hearing and a high-frequency boost to increase detail and intelligibility.

    For their monitor sound, users can opt for a mono mix (one mix, and the pan control adjusts the volume for the left and right ear) or a stereo mix. The latter provides two options: With Focus mode switched off, the pan control will change the left/right volume; with Focus mode switched on, it will determine which of the two input signals will be heard louder, creating a personal mono mix tailored to the musician’s needs.

    An infrared sensor helps to easily multiple bodypack receivers to one transmitter. ​XSW IEM includes a stereo bodypack receiver with in-ears and batteries and a stereo transmitter with antenna, rack-mount kit and a power supply with various country adapters.

    When starting out, using one transmitter and any number of bodypack receivers is a cost-effective way to monitor a band’s sound. At a later point in their career, they may want to create more individual mixes, and can do so by simply adding an additional IEM transmitter.

    XSW IEM retails at $929 CAD (US MSRP) plus tax, additional receivers and transmitters at $529 CAD (US MSRP) each.

    XSW IEM is available in five UHF frequency ranges which are aligned with the XSW family of wireless microphones and instrument transmitters.
