Music Ducking

You’ve got music playing nice and loud but, it’s time for another announcement. Sure, you could mess with your levels every time, but who’s got time for that. Simply press the Music Ducking button, and channel 2 will automatically turn down whenever you speak into the mic on channel 1.

Keep Everyone’s Ears Safe from Feedback

Feedback Eliminator

Ever get a little too up close and personal with the microphone only to hear a loud, ear-destroying squeal? That’s commonly known as feedback. And it’s an unfortunate issue that physics won’t change its mind on. But wait! Hit the Feedback Eliminator button and laugh in the face of those silly acoustic laws.
