Overview

K9-US Professional Dual Digital UHF Wireless Mic System

Performance, reliability and pro features that 2.4 GHz just can't match.

A premium, dual-channel UHF digital wireless lavalier microphone system designed for filmmakers, videographers, and high-level content creators who demand crystal-clear, broadcast-quality audio.

Delivering Ultra-Wide UHF Spectrum, Pro-Level Performance and Reliable Power

Operates in the ultra-wide 550–960MHz spectrum with GPS-based frequency updates, auto frequency scanning, and selectable RF output power. Delivers a strong, reliable transmission even in crowded RF environments, outperforming 2.4GHz systems.

Powerful Bodypack Transmitters with Industry-Leading Dynamic Range

Record cinema-quality sound with the K9TX bodypack transmitters that offer locking 3.5mm TRS mic/line inputs and a remarkable 130dB dynamic range to capture every nuance—from soft whispers to loud vocal bursts with stunning clarity. 

Miniature Lavaliers that are Discrete, Rugged and Ready for Real Action

Two ultra-compact 3mm lavaliers are included. Engineered for durability and discretion, they deliver broadcast-quality audio performance in even the toughest environments. Featuring IP67 water and dust resistance and Kevlar reinforced cables, providing exceptional strength and reliability from desert shoots to stormy weather.

Portable Dual Receiver with Dual LED Screen and Flexible Output Options

The lightweight dual receiver offers both analog (120dB) and digital output options. 
A top-mounted LED display makes status monitoring easy in audio bags or on camera. Elbow-style antennas ensure optimal positioning, while SMA connectors support antenna distribution systems and external antennas for added stability.

32-Bit Float Onboard Recording Transmitters

Transmitters features on-board 24-bit and 32-bit float recording, perfect for environments with heavy RF interference. The included 32GB microSD cards (expandable to 256GB) offer extensive recording capacity and peace of mind in challenging recording environments.

Advanced Timecode Synchronization

Your recordings are always in sync with built-in frame-accurate timecode synchronization. Jam sync to external timecode sources via 3.5mm, or wirelessly with the Saramonic TC NEO timecode generator (sold separately). With 8 programmable sync groups, managing complex multi-system setups has never been easier.

Total Control with the Saramonic System Mobile App

Take full control of your setup with the Saramonic System app. Remotely manage frequencies, gain, power, mute, transmitter recording, timecode sync, and more without touching the hardware. Enhance your workflow and ensure your audio remains flawless, especially on fast-paced film sets or a dynamic live shoot.
