MG100HDFX & HeaphoneS


Hi everyone,

                            I've a very similar question to one that has already been asked. 

Is it safe to use the headphone/line out without any speakers connected to the rear on a MG100HDFX head?

Also, when I do use the speakers, do I have to use both speaker outputs at the rear or is using  just one ok?

One more thing, is it safe to use my faulty G80R CD as a speaker cab with my MG1000HDFX, I'll be using nothing like full power, just having fun in my room?

Thank you in advance,

Hi Vox,

Thank you for your message, you can run an MG without a cab, You can use either speaker sockets as they’re both connected.

The G80RCD as a cab is not recommended as the speaker will be underpowered.
