The Sennheiser SKP 2000XP-GW is a professional plug-on transmitter designed for use with wired microphones, converting them into wireless systems within the 558-626 MHz frequency range. This transmitter is particularly valuable for broadcast, film, and live production where the audio quality of a specific wired microphone is required, but wireless mobility is essential. It features a built-in, high-quality preamplifier with switchable 48V phantom power, allowing it to power and interface directly with professional condenser microphones that require phantom power, such as shotgun mics or large-diaphragm studio condensers. The unit also includes a line-level input with adjustable gain for connecting other audio sources like instruments or playback devices. Its robust metal housing and secure locking connectors ensure reliability in demanding field conditions.

The transmitter operates on the evolution wireless G4 platform (or similar 2000 series), offering stable RF performance and easy integration with compatible Sennheiser receivers. It features a clear OLED display for monitoring settings such as frequency, RF and audio levels, battery status, and gain. The adjustable audio gain allows for optimal level matching to prevent clipping and maximize dynamic range. The unit is powered by two AA batteries, providing several hours of operation, and includes comprehensive power management features. An integrated belt clip and a standard 1/4-inch thread permit flexible mounting on a camera, belt, or stand. The ability to remotely control certain parameters from the paired receiver enhances operational efficiency during complex shoots.

As a B-Stock item, the SKP 2000XP-GW is a fully functional transmitter that may have been returned, demoed, or have minor cosmetic imperfections, but it delivers the same performance and reliability as a new unit at a reduced cost. This presents an excellent opportunity for broadcasters, sound mixers, and content creators to acquire a versatile and professional wireless tool that extends the functionality of their existing high-quality microphones. By combining transparent preamp quality, flexible powering options, and robust wireless transmission, this plug-on transmitter is a key component for professional wireless audio workflows.
