Markbass Blackline 101 hiss problem

[Nuno O.]

Hi,

I just got a Markbass Blackline 101 and noticed a hiss even if nothing is connected. However, when using the headphones no hiss is heard. Is this something that others are experiencing or might be something to do with this amp or the electricity installation in my flat?

Thanks in advance for your tips and suggestions.

That indicates the hiss is sourced in the power amp section, so it's probably not the mains. It's an inexpensive amp so it may be normal for it.
