    Default Is this wrong!!!?



    Hi all,

    I got my amp from thomann today, the t.amp 1400.


    a few issues....

    I need to buy a deeper flight case for it.

    It hums when i turn the volume up on the amp!

    and ive turned it off but the fault light is appearing!!!!! It very slowly dims after a few minutes after power off.
    (Doesnt appear when on)

    Whats wrong and why is these (second two) things happening!?

    Please help.

    As regards the fault light i have no idea but hum through the amplifier is usually caused by poor shielding on the signal cables

    Fault light could be it just turning off? Sort of system shut down procedure.

    I thought of something like that but wasnt sure it was the fault light. No help in the manual.

    Mixer to amp is the normal culprit for amp hum however i worked a venue the other week where the hum was coming off the mains. I changed my extension lead onto a different ring main and the hum vanished

    I got the leads from Simon Cowey. Ive looked at them and they look ok though.

    I have the German lead with a convertor thing on it.

    The power info is:

    200v-260v
    50hz-60hz

    Is that just an average IEC kettle lead?

    The fault lights do come on when you turn it off for a while until the current has discharged. Mine does it and I don't think it is a problem.

    The hum could be due to a ground loop. Have you tried changing the position of the ground lift switch?

    Does it happen if you have no inputs plugged into the amp?

    It is just a normal kettle plug lead. I use a different one to the one supplied with a 13amp plug on it.

    The plug I have is IEC 250v 13A.(english plug) Is that ok with the T.Amp 1400?

    And the hum comes out of the speakers. Not from the amp

    Is the ground loop the switch on the back? 0---0 0-\-0 Sort of thing?
