Tone Control Bypass engages the soundstage depth circuitry, which uses advanced biometric feedback mechanisms and transmogrifiers to alter the soundstage depth.
To alter the soundstage *width,* you need to rotate the bass control all the way up, then down, then back to its default position.
To alter soundstage *height,* you need to roate the treble control all the way down, then up, then back to its default position.
To avoid smart-ass replies, you need to post questions about electronics in the appropriate forum, ie, not the forum called "Loudspeakers."
