Saramonic K9 Dual-Channel Digital UHF Wireless Audio System for Filmmakers

Meet K9, Saramonic’s first digital UHF wireless microphone for professional filmmakers. Featuring an ultra-wide 550-960MHz UHF spectrum and audio frequency scanning, it resists interference in crowded RF clutter. With digital transmission, a 130dB dynamic range, and 32-bit float onboard recording, the system captures detail-rich recordings and ensure safe backup. Timecode-enabled, K9 syncs with cameras down to the frame, eliminating manual syncing in post-production. The 3mm diameter ultra-miniature lav mic delivers unmatched durability, and flawless sound in any environment. With Saramonic System, all info and configurations are taps away on the phone, giving recordists easy full control.

Incredibly Stable
Using the reliable UHF spectrum with GPS-based frequency updates, the K9 digital wireless microphone system outperforms 2.4GHz with superior interference resistance. Auto frequency scanning finds the cleanest channel, ready for global action.

Every Sound, Pristine
Record in cinematic quality. Digital transmission ensures no audio quality loss, while a 130dB input dynamic range perfectly captures everything from shouts to whispers, and the 120dB analogue output reproduces sonic detail. True, clear and immersive.

Small, Rugged, Ready for Action
The K9 comes with the smallest 3mm miniature lavalier mic in the industry, easy to hide so you can seamlessly fit it into your on-camera look. Featuring IP67 dust and water resistance and Kevlar-reinforced cabling, it stands up to everything from rain to desert and the wear-and-tear of daily use.

Make Every Sound Heard
Unexpected audio spikes or whispers on set? No compromises. With K9’s 32-bit onboard recording, fix it all in post - every detail, whether clipped or too quiet. With 32GB of storage, your audio is safe, so you can tell your story with peace of mind.

Sync Effortlessly, Work Faster
Audio and video drift apart? K9’s timecode keeps everything in sync. Wirelessly connect to a timecode generator (purchased separately) via Saramonic System - one tap aligns all devices to the exact frame, or use a 3.5 mm wired connection to sync with 3rd-party gear. No more manual post-production headaches.

Take Total Device Control
Introducing Saramonic System, an audio smart control app that makes the K9 work more efficiently. You can remotely control up to 48 devices - manage device groups, activate sleep mode to extend battery life, update firmware version and much more. Everything you need is right at your fingertips.

Pure Design, All on Point
Inspired by Nordic minimalism, the K9 is sleek yet powerful. The receiver features a 1.47" colour display and an innovative top screen, making it easy to read at a glance, even in direct sunlight. Hidden buttons prevent accidental presses, and 8 coloured tags help you quickly identify devices. So you can focus on the story, not the gear. And the durable metal bodypack transmitter is lighter than a phone at 125g, ensuring comfort movement for actors during shoots.

Power Through the Day
The K9 transmitter lasts up to 9 hours, and the receiver up to 8 hours. You can swap batteries in a snap - compatible with multiple types - or power via USB-C while recording, keeping the sound rolling nonstop. For eco-friendly workflows, opt for rechargeable batteries and an 8-slot charging dock. Power your day, your way.

Fits Every Setup
The K9 comes with a variety of adapters, compatible with cameras, recorders, computers, mixers and phones, offering versatile use in various settings to meet your needs. Great for  recording, live streaming and stage shows.
