The lack of a published spec for noise may just say it all, R.

If you have the Gain Staging correct and still hear hiss noise, then the unit is too noisy to use.

Correct Gain Staging is to always have the Output or Master volume set LOWER than the ones before it. Get any gain at the preceding controls and just barely crack the output until you get the needed level, then check for noise.

If it hisses then, it is a noisy piece of gear. Toss it.
