No sound , no signal !

Welcome.
This is not how it should be. Open a support ticket, please.

Silly question, but did you go straight to browse or have you also tried the tuner?
Do the LEDs above the chicken knob flicker when you plug a cable into the input and just touch the end of the cable?

Hello , I just receive my KEMPER , and I can't try it !
There is no sound and no signal in the "input" (rear and front) . I turned it on and go to "browser" , but nothing .I've tried many cables in the input .

Thanks
Gwen

Please check out the manual first. Are the output setted right? F.e. Main out stereo? What about headphone out, also no signal? Output led on when playing. Output volume checked in the output section?

This may sound silly but did you turn the master volume up or just the volume for the profile. Output volume must be up eg mainouts/monitor etc

I had the same issue - see here:

UPDATED/FIXED New owner - no sound when using front input please help

Hello , I havé no sound with all inputs !

Here is the issue that is mentioned by Aussiejoe "Unit went back to the distributor, turns out it was an unseated/improperly seated internal connector that was the issue."
