hello, I have a Yamaha RX-750 Stereo, my equipment sounds good unless I activate PURÉ DIRECT, if I deactivate the button nothing sounds, therefore I have no balance, I have no bass, I do not have highs, which may be, help me
I cannot think of a reason why you'd not be able to portray the same audio you are successfully portraying while the receiver is set to its PURE DIRECT mode if you disengaged that mode? What happens if you try engage the STRAIGHT mode?
All I can suggest is that you try a factory reset. If this fails to rectify the situation then I'd suggest that it is a fault you'd need a Yamaha service centre to look into.
