Query: Hisssssssss

I bought this and returned it the same day. Static hiss is the problem. When recording in a silent room, the created file has a large amount of quite loud static/hiss. The voices were recorded quite well, but I found the amount of background hiss simply unacceptable. Very dissapointing as the recorder worked well otherwise. Note that I also used an Olympus ME51S microphone, the hiss was present whether it was used or not.
