I have noticed that when recording with the internal microphone there is a
very slight amount of processor noise, it is only noticeable when things are
very quiet. Is this typical for this unit? I assume if I got a real mic it
would go away. The noise is absent while recording off the FM tuner.
Also in the menus where you choose a range of items such as playback speed, if you left-arrow to decrease speed does it go to the minimum value or wrap around to the maximum again?
