Pathos Logos - Volume control problem


Posting for a friend.
Turned the power on, and once ready to go.
Just touch the volume control from zero to the first notch up and the volume starts blasting (at almost full gain)!
Have to immediately power down to avoid any possible damage on the speakers.

Anyone any suggestions on what I should do? other than sending the unit out to the dealer for service. Would appreciate any input.

Thanks

You need to list the whole system. The other components may play a factor. Also list exactly how everything is connected.
oppo bdp83
connected to micromega dac via coaxial digital
pathos amplifier via unbalance connection

no phono in the amplifier
