Hello.
NAD T748 V1
Works fine, just one problem.
Analog Source one......no sound.
All auther sources works fine but the sound appears only after 10 seconds
That is, if I select an input, it appears on the display but the sound will only appear after 10 seconds. There is never any sound at analog input number 1.
Factory reset doesn't help.
Last firmware is installed.
Thanks
