Hi!

I'm new in the marshall world and don't have any experience in speakers but I recently have bought a Marshall Acton Bluetooth, but the speaker when turned on and no sound have a static noise (like zzzzzz something like that) and even when I put some sound the noise continues but I only can detect if I put my ear in the speaker. 

It's that normal? I'm asking because I have the speaker connected with my Amazon Echo Dot and I want that they stay always on and I don't want that static noise...

Regards.

Good day,

I try connect Marshall Acton to my PC with Bluetooth 2.0, but require PIN code. 0000 or 1111 not work.
What is the pin on this speaker?
