This is my first ear monitor system so i decided to go with a middle of the road system. Not wanting to break my bank account but i also didn't want a cheap unit either,OK here we go. Solid unit but first thing the ear buds are horrible, you will definitely need an upgrade. And two it does NOT come with an antenna extension for rack mounting which was include in earlier models, it has all the other hardware but no extension which i had to go to there web site and purchase. Nice unit but if your a working musician you will have a few extra expenses to get you going.
