Thanks for clarification, could not see a physical button or mention of it in any review.Hi - The Tucana does have balance control. My Tucana 2 does anyway!
This button allows the user to vary the sound balance between the loudspeakers. Turning the volume knob anti-clockwise will move the sound to the left, clockwise will move it to the right. The balance control is not unique to the input in use and will affect all sound sources.
is the button on the handset?
ignore last comment, I have just seen it.
It was the original Tucana I was looking at though
