Why does the Ur28m power off automatically when using 1/8in 2tr(line) output.
I sometimes use the Ur28m without my computer and just play my Ipod through the 1/8 inch output but after about 20 mins it shuts down and I have to turn it back on. There must be a way to change this feature. If it powered down after an hour or so that would be fine. But every 20 mins is very annoying.
