I accidentally switched my Mira 3 to phono inputs when using the volume knob today while a CD was playing. I noticed I could still hear the music faintly, even though the CDP is connected to the CD inputs.
Is this common, possibly due to the sensitivity of the phono inputs?
There should be no problem unless you have the CD playing while using the phono inputs. Since all inputs share a common ground path, there is often a small amount of bleedthrough between inputs. If you don't have a turntable, you might try some shorting plugs in the phono inputs. Unfortunatley, right now, I think Cradas is the only company selling such devices and they extract a fairly heavy price for something that used to be a give away in years long past.
