I'm confused. When I pan the signal on the source, the input levels on my Tascam DP008EX make sense - when the signal is panned left the input level display for channel A is high and when panned right, the one for channel B is high. However, this is not reflected in what I hear in my headphones, where the balance remains constant.
Furthermore, with the input signal panned fully left, the pan knob for channel B does nothing to the monitor signal, while the one for channel A gives a loud signal in both ears when turned left, and a quiet signal in the right ear when turned right.
Can someone explain what is going on please?
