And with dual TRS / XLR inputs plus a stereo 1/8 aux input, you can plug in all of your gear without odd cables and adapters.- NO MIXER? NO PROBLEM: Connect any combination of audio sources, including guitar, microphone, keyboard, or DJ mixer. The built-in 2-channel mixer on the rear panel has two combo input jacks for easy plug-and-play plus an 1/8" stereo line in for connecting the audio output from a smartphone or media player.- POSITIVE FEEDBACK: MUSIC DUCKING- Youve got music playing nice and loud but, its time for another announcement. Sure, you could mess with your levels every time, but whos 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. FEEDBACK ELIMINATOOR- Ever get a little too up close and personal with the microphone only to hear a loud, ear-destroying squeal? Thats commonly known as feedback. And its an unfortunate issue that physics wont change its mind on. But wait! Hit the Feedback Eliminator button and laugh in the face of those silly acoustic laws.
