ShowLink® Live Frequency Swap, Zero Dropouts | Dallas Sound Guys

We saw interference rising, switched channels mid-show, and the audience never heard a thing.

• Live RF interference detected during program
• Seamless frequency change on an active transmitter (seconds, no audible hit)
• Clean, uninterrupted audio for presenters & recording

In a crowded RF environment, a presenter’s mic began trending toward a problem frequency. Stopping the show wasn’t an option—and neither was risking a dropout.

• Active RF monitoring: We watched the spectrum and noise floor in real time to spot the trend early.
• Axient Digital + ShowLink® control: Because ShowLink provides a dedicated 2.4 GHz control path to ADX transmitters, we could push a new frequency to the live mic without touching the talent or pausing the show.
• Pre-planned backups: Clean backup channels were coordinated ahead of time, so the swap was instant and invisible to the room.

No dropouts. No RF noise. The presenter continued, recording feeds stayed clean, and the audience noticed…nothing (which is exactly the point).

• Wireless: Shure Axient Digital with ADX transmitters and ShowLink® remote control (enables on-the-fly parameter changes, including frequency).
• Coordination: Pre-coordinated primary + backup channels; directional antennas and proper gain structure.
• Monitoring: Real-time spectrum observation and proactive thresholding to act before issues are audible.

Will the audience hear a “hit” when you change frequencies?
With Axient Digital ADX + ShowLink and pre-coordinated clean channels, the change can be executed seamlessly mid-show.

Do you need special hardware for ShowLink?
Yes—Axient Digital’s ShowLink workflow uses a dedicated 2.4 GHz control link to supported ADX devices (via a ShowLink access point) so parameters can be adjusted live.

Can you do this with multiple mics on a bigger show?
Yes. We scale the same approach—monitoring, backup channels, and ShowLink control—across all active transmitters.
