Here you can see Bruno Mars perform at the 2016 Grammy Awards. Mars’s front-of-house mixer Chris Rabold and monitor engineer Ramon Morales have been ecstatic with the sound quality and reliability of the Digital 9000. Currently, the pair is in rehearsals for Bruno Mars’ upcoming 24K Magic Tour, where the Digital 9000 will serve as the tour’s primary wireless system, making the decision to use it in a broadcast environment for the first time an easy one. “In a situation like the Grammy Awards, you have a very limited amount of time to dial in your settings,” Rabold said. “What’s great about Sennheiser and the Digital 9000 is that your sound is essentially there as soon as you turn the system on.”

Microphone can be seen in the photo.
