K9 | Professional Dual Digital UHF Wireless Lavalier System

The Saramonic K9-US is a professional dual digital UHF wireless microphone system built for filmmakers, videographers, and high-level content creators who need a seamless, remote-controlled audio solution for two people. It features 24-bit digital wireless sound transmission and is equipped with miniature lavalier mics, giving you detailed, cinema-quality sound, while keeping the setup discreet. The system features a dual-channel camera-mount receiver that connects to cameras, mixers, and recorders with XLR or 3.5mm analog outputs, and digitally connects to mobile devices and computers via USB-C. The transmitters also feature 32-bit float or 24-bit on-board recording with advance timecode synchronization, ideal for avoiding dropped signals and heavy RF interference while syncing perfectly to your project in post-production. The transmitters and receiver feature rugged aluminum construction, making them tough enough for demanding field production environments.

Ultra-Wide UHF, Power, and Performance Professional Productions Need
The K9-US is designed for professionals, with the performance and power pros need. It features an ultra-wide frequency UHF operating spectrum of 550-960MHz with GPS-based frequency updates and advanced auto frequency scanning. It also includes three sets of frequency specific antennas, 550-608, 614-698, and 863-960MHz, letting users choose the best frequency band for their needs, and not forcing you to cut the antennas. The transmitters also feature selectable RF power of 10, 25, 50, or 100mW. Giving users the power and reliability needed for professional applications and that 2.4GHz systems just cannot match, especially in heavy RF environments or scenarios with lots of obstacles.

Powerful and Flexible Body Pack Transmitters with Remarkable Dynamic Range
The K9TX transmitters feature locking 3.5mm inputs, allowing you to transmit microphones or line-level signal. The transmitters feature 130dB dynamic range, allowing you to capture every sonic detail from a whisper to a scream. The transmitters are also compatible with 3.5mm TRS Sennheiser pin-out mics and feature selectable 3V or 5V, allowing you to choose hundreds of other lavalier, headset, and other mic options to expand the system further. Switch to line-level and connect to mixers, music players, or any line-level device output you want to transmit wirelessly to the receiver. Perfect for capturing an IFB mix from the production mixer or recorder for a real-time feed to directors, producers, and camera operators.

Miniature Lavaliers that are Discrete, Rugged, and Ready for Real Action
The K9-US includes two miniature lavaliers that are not just tiny but can handle anything your wild production throws at them. Designed to capture crystal clear audio these tiny lavaliers deliver unmatched durability, and crystal-clear sound in any environment. Ultra-compact and discrete with a 3mm diameter, making them ideal for concealing in clothes or in costumes on set. But they are not just tiny, they are tough. They are IP67 rated, for resistance to water and dust and feature a Kevlar® reinforced cable with a remarkable tensile strength. Ensuring these lavs can handle the toughest environments from the desert to a rainstorm and the wear and tear of a pro production.

Portable Dual Receiver with Dual LED Screen and Adaptable Outputs
The lightweight K9RX dual cam-mount receiver features flexible output options, allowing users to maximize their recording capabilities. It features two locking 3.5mm analog outputs that can be configured to your needs, with a generous 120dB of analog output. A USB-C port give you a digital output for mobile devices and computers, or an external powering input to power the receiver with a battery pack. A 2nd LED display on top of the receiver provides easy viewing of receiver status while in a mixer bag or on-camera. Capable of running up to 20 systems simultaneously in the same area, the K9-US is designed to handle large productions with ease. The elbow-style antennas allow easy positioning for optimum reception when on camera or in a bag, and the SMA connection allow the use of antenna distribution systems, and external antenna paddles for even more stability and flexibility.

32-Bit Float Recording Transmitters with Advanced Timecode Synchronization
The K9TX transmitters feature both 24-bit and 32-bit float on-board recording with advanced timecode synchronization. Ideal for situations and scenarios with heavy wireless interference, allowing you to record your talent and ensure frame accurate synchronization with your camera or recorder. Each transmitter includes a 32GB MicroSD card and can be expanded up to 256GB, allowing an incredible amount of recording power. The K9TX transmitters can jam sync to external timecode sources into its 3.5mm input and wirelessly using the Saramonic TC NEO (Sold Separately). The transmitters can also store up to 8 sync groups, allowing you to easily change your configuration as you change timecode sources.
*Simultaneous recording and wireless transmission are disabled within the US*

Total Control with the Saramonic System Mobile App
Remote control of system settings and configurations of the K9-US system is easy with the Saramonic System app. Allowing you to remotely scan and select frequencies, coordinate multiple systems, adjust gain and output settings, manage power settings, mute and unmute transmitters, and engage the transmitters' backup recorders—all without physically handling the devices. Ideal for filmmakers who need to work fast, streamlining their workflow, and ensuring great sound every time.
