What customers say
Professional audio engineers overwhelmingly praise the Shure ADX FD HH for its mission critical reliability and pristine audio quality.

Its high value stems from unparalleled dependability where failure is unacceptable, setting the industry standard for wireless performance.
Know before you buy
Frequency Diversity allows the transmitter to send audio on two independent frequencies simultaneously. If one frequency experiences interference, the system automatically maintains the audio signal on the second frequency, ensuring a seamless, uninterrupted performance.
Yes, the ADX2FD features an interchangeable capsule design. You can easily swap the included KSM9 condenser capsule for other compatible Shure microphone heads to suit different vocal styles or acoustic environments.
ShowLink provides real-time remote control over all transmitter parameters. This allows you to adjust gain, frequency, or RF power settings from the mixing console without needing to physically access the transmitter on stage.
The AES 256-bit encryption is a standard feature of the Axient Digital system designed for secure, private transmission. It can be enabled within the system settings to ensure your audio signal remains protected from unauthorized interception.
The SB920 rechargeable battery provides up to 9 hours of continuous operation. You can monitor the remaining battery life in hours and minutes directly from the transmitter display or the receiver software.
The cardioid pattern is ideal for general vocal use as it captures sound primarily from the front while rejecting noise from the rear. The supercardioid pattern is more directional, offering better isolation and higher gain-before-feedback in loud stage environments.
