Saramonic K9 XTX UHF Wireless XLR Plug-On Transmitter

Saramonic K9 XTX UHF Wireless XLR Plug-On Transmitter — A digital UHF plug-on transmitter that turns an XLR microphone or line-level source into a wireless channel for the Saramonic K9 system. It locks onto the XLR output and supplies selectable 3, 5, 12, 24, or 48 V phantom power, or none for dynamic microphones and line sources. Transmission covers 550 to 960 MHz with GPS-based frequency updates, a 130 dB dynamic range, and up to 150 m of range.

The XTX records 24-bit or 32-bit float WAV files to microSD (64 GB included, up to 256 GB) and reads and generates SMPTE LTC timecode with 0.15 ppm clock accuracy, synced through the Saramonic System app or by cable from a third-party timecode box. K9 systems sold and operated in the US cannot transmit wirelessly and record onboard at the same time. Two AA batteries provide 7+ hours, USB-C supplies external power, and a large color screen shows device status.

Available as the transmitter alone or as the XTX Kit (sold in the US as the K9 Duo Kit), which adds a K9 bodypack transmitter with a 3 mm lavalier and a K9 dual-channel camera-mount receiver.
