This version was designed to be portable (smaller dimensions and weight) and therefore to make travel/touring easier. It's also meant to last longer (built out of proper wood - wenge), to sound better (better components) and it has 6 independent audio outuputs (1/4 inch jack) that allow manipulation of the outcoming sound and eventually to do multi-channel performances. It also has a bigger variety of controls, amongst other things.
Consists of: 6 Radios, 6 Keys, 6 Tunning dials, 6 Volume controls, 6 AM/FM switches, 6 LED lights, 6 antenas, 6 audio outputs and 1 power socket.
