Thank you for the update will have to check it out, don't have a network connection near the amp so will have to get a router bridge or extender.

So I am guessing the new firmware didn't solve the problem?

@lordrootman

Update can be done through the USB port too I forgot about it. BTW did you do a factory reset after doing the firmware update as its recommended in the manual.

@jiya3600 Yes I did reset to factory but no any improvement on distortion 
do you see any improvement on distortion or noise ?

@lordrootman

I just did the firmware update, did a full reset & reboot issue not resolved. I tried every single input as soon as the tone control is engaged for that particular input there is hum and distortion from both channels. The hum and distortion is not very loud but it's there no both channels.

As soon as I disengage tone control and put any input in direct mode completely silent. Don't know what to do at this time!
