Michi P5 Preamp Tone control Distortion

@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!

I Have the P5 and wasn't aware of this problem. I have never tried the tone controls, I'm surprised so many of you are using tone controls. 

@ron1264
can you try tone control 
you don’t have to use it just turn on and see if you can hear any distortion hissy or hum
