Any para psychologists out there ?
Used to assume this was caused by my room. Now no idea. Symptoms :My amp has 2 volume controls, one for each channel.with left hand ser volume, when I turn up right hand volume only I hear the sound basically centred between speakers in other words predominantly to the left of my right hand speaker and I am sonically unaware of right speaker’s presence unless I get up really, really close to it. It quite literally seems to disappear and the sound seems to be generated from inside my rather hefty bureau situated between the 2 speakers. rather as if a balance control had been turned to the left but of course a) my amp has no balance control and b) the left hand speaker has zero volume so the word balance is not applicable. My left hand speaker seems perfectly normal , indeed predominant in the bass.
So I proceed to swap l and r input from deck to my phono amp. Disconnect left input. Hello buzz on right hand channel with no left connected. When I connect left, buzz disappears and all is well ( apart from the original imbalance ). Swap inputs and buzz changes sides.
So, one channel would seem to have an earth buzz when the other rca is not connected. Buzz disappears when other rca is connected. No hassle, presumably easy to sort. But my question is : when using one earth for both channels can this cause as if it were a suck out of highs andmids in the earth less channel enough to affect lateral lobing enough to simulate a central image ? I can’t believe I have written that.
