For Global Production
Designed with ultra-wide 550-960 MHz UHF coverage and GPS-based frequency system, K9 XTX digital wireless microphone system automatically adapts to local RF regulations wherever you work. It's the perfect choice for professionals on the move who need a portable wireless system with superior range and more reliable connectivity than typical 2.4 GHz systems.
Broad Mic Support
The plug-on transmitter design works seamlessly with any microphone or line-level source via a standard 3-pin XLR connector. Phantom power is selectable at 3V, 5V, 12V, 24V and 48V, and can be turned off for use with dynamic microphones and line-level devices right out of the box.
Reliable Recording
With support for 32-bit float internal recording, the K9 XTX captures a 130 dB dynamic range that not only delivers distortion-free audio but also adapts better to complex sound environments. It delivers clean, reliable audio in unpredictable recording scenarios while providing greater flexibility and protection during post-production.
Synchronization
K9 XTX keeps sync simple from the first take. Built-in timecode reading and generation, wireless sync through the Saramonic System App, and wired input from third-party timecode devices—keeping audio and video precisely aligned while saving time in post-production.
Saramonic System App
The Saramonic System App enables remote control of up to 48 devices, allowing you to manage device groups, activate sleep mode to extend battery life, update firmware, and more. This means you can make adjustments to your audio settings without having to physically touch the devices, making it easier to work when you're on set.
Extended Runtime
Powered by two exchangeable AA batteries, K9 XTX delivers 7+ hours of operation. The display shows battery status at a glance, while USB-C external power and charging support give you extra flexibility when the shoot runs long.
The K9 XTX delivers stable transmission up to 150 m.
The locking XLR connector ensures a firm and secure fit.
The K9 XTX features a large color screen with easy-to-read menus and controls, so you can easily check device status and get instant feedback during production.
Built to perform from -30°C to 60°C, the K9 XTX withstands extreme cold and heat in demanding environments. When paired with the waterproof case (sold separately), it achieves IP66-rated water resistance, providing added protection against sweat and moisture in wet outdoor and production settings.

Wireless frequency regulations differ from region to region. If you're unsure which K9 frequency range is right for your area, feel free to contact your local Saramonic sales representative or retailer, who can help you choose the appropriate frequency range for your region and application.
Yes. The K9 XTX features a standard 3-pin XLR connector and works with dynamic microphones, condenser microphones, recorders, and other XLR-equipped audio devices.
Choose a plug-on transmitter if you want to convert a standard, wired handheld or shotgun microphone (like a SG MIC) into a wireless mic. Bodypacks are better for lavalier mics, headsets, and situations where you need to hide the transmitter in clothing. Check more from this article.
Absolutely. By eliminating long microphone cables, the K9 XTX allows crews to move quickly between locations, reduce setup time, and maintain a cleaner production environment—especially useful for documentaries, news gathering, and fast-paced field productions.
The K9 XTX works with the Saramonic System App, allowing sound teams to remotely monitor and control up to 48 devices from a smartphone or tablet. Users can adjust gain, change frequencies, mute channels, and perform firmware updates without physically accessing transmitters, helping streamline workflow on complex multi-talent productions.
Unlike traditional plug-on transmitters that rely on analog compander technology, the K9 XTX uses a digital wideband UHF transmission system with up to 130 dB input dynamic range to preserve the natural sound and dynamics of professional microphones. Built-in 32-bit float onboard recording also provides a high-quality backup recording for added production security.
The K9 XTX comes standard with 64 GB of high-speed internal storage, which provides hours of reliable backup recording out of the box. For extended documentary shoots or multi-day productions where offloading data immediately isn't possible, the transmitter supports external storage expansion up to 256 GB via a dedicated TF card slot, giving production crews maximum flexibility and absolute peace of mind while capturing critical 32-bit float audio.
The K9 XTX features an integrated timecode generator and reader that can synchronize wirelessly within the Saramonic ecosystem or via cable with external master clocks and compatible cinema cameras. By embedding matching timecode into recorded media, editing software such as DaVinci Resolve and Adobe Premiere Pro can automatically synchronize audio and video, significantly reducing post-production workflow time.
