just recieved a new naiant box.will try to post pix soon. i have not yet field tested it. in the shop i have connected a pair of schoeps and a pair of b and k,s. both sounded clear and quiet. no hum or noise while gain was pushed all the way up.this box runs on 4 double a batteries. have not tested to see how long they will run until they die and box shuts down. box has two individual led meters for power and gain. low and high toggle switches for gain control. not sure of the exact measurement. one mini jack line out one mini jack mic in(never going to use it). 2 xlr in and 2 xlr outs. battery tray on one side. external power jack on the other side. more info to follow once it has been tested in a live situation. jon makes these boxes by hand lovingly.aluminum cases and hand soldered. that is all. todd
