Saramonic has released updates to its K9 wireless microphone system and expanded its product lineup with new Bluetooth timecode generators. The changes address a previously reported RF behavior and add timecode functionality aimed at professional production workflows.
550 MHz RF Behavior
Both the Deity Theos and Saramonic K9 wireless microphone systems were observed to emit a brief signal at approximately 550 MHz during transmitter power‑up, regardless of the selected operating frequency.
In RF‑dense environments such as broadcast facilities, stadiums, and theaters, this behavior raised concerns due to the potential for interference with other wireless equipment. In some venues, this led to restrictions on the use of systems exhibiting this behavior.
Firmware Update for the K9 System
According to Saramonic, the 550 MHz power‑up transmission has been addressed in a firmware update for the K9 system. Following the update, the transmitter initializes directly on its assigned operating frequency without emitting the transient signal at 550 MHz.
This change reduces the likelihood of unintended interference during power‑up and aligns the system more closely with professional RF coordination requirements.
Timecode Ecosystem Expansion
In addition to the firmware update, Saramonic has introduced the TC‑NEO Bluetooth timecode generators. These units can be jam‑synced with compatible devices, including the K9 system, enabling timecode‑based synchronization for multi‑camera and dual‑system audio workflows.
This expands the K9 ecosystem and brings it closer to feature parity with competing wireless systems that offer integrated timecode support.
Battery Design Considerations
The TC‑NEO timecode generators feature non‑user‑replaceable batteries. Saramonic has stated that it plans to support battery replacement through service options, including mail‑in replacement and the potential sale of replacement batteries.
Long‑term implementation and availability of these options remain to be seen.
Summary
With the firmware update addressing the power‑up RF behavior and the addition of Bluetooth timecode generators, Saramonic has made functional updates to the K9 system.
These changes may be relevant for users evaluating wireless audio solutions that require improved RF behavior and timecode integration for professional production environments.
