Hi there !
First, sorry for incoming mistakes, I am a french guy
. So here is the situation: I just received from Thomann my new rig composed of gk mb 500 and gk no 212 8 ohms. As the title implies, I am experiencing some hiss coming from the speakers... this happens no matter what I set as Eqs and it happens too when my bass isn't plugged in and even when the master volume is zero. Of course, it increases as I up the volume. Well this hiss isn't that annoying when I play but it bothers me when doing nothing... does some of you have clues of what is happening ?
Thanks for your answers
