Sennheiser XSW IEM SR Wireless In-Ear Monitor Transmitter

Pair this half-rack stereo UHF transmitter with XSW IEM bodypack receivers to build your own in-ear monitor system -- Sennheiser's XS Wireless makes it easy.

Part of the Sennheiser XS Wireless IEM system, the XSW IEM SR transmitter is a single half-rack stereo UHF transmitter with rugged metal housing. Package includes one XSW IEM SR Transmitter, one Antenna and one NT 12-5 CW power supply with power adapters.

The rugged XS Wireless IEM transmitter features metal housing designed for ever-changing stages, rehearsals, and travels. The transmitter can be operated stand-alone or as part of a rack with the optional rack mount kit. The removeable BNC antenna allows for various mounting options.

The backlit front interface offers easy and simplified access in a clearly arranged menu. Just a few clicks, even on dark stages, and you can optimize input signals, link additional receivers with the infrared panel, or simply monitor the audio status.

The two XLR combo inputs on the back are open for both XLR or 6.3 mm (1/4 inch) connections, resulting in a high flexibility with different cabling options. A 6.3 mm (1/4 inch) headphone jack output on the front can be used for wired, stationary monitoring or as a quick overview option in larger setups.

Advanced transmitter settings like gain, input sensitivity, mono or stereo options, and easy frequency management with eight frequency banks with 12 precalculated channels each allow perfect monitoring for any demand, on any stage and in any location.
