Craig,

The "balance" control - if you have configured the Sub AF control
as balance - will increase the audio level in one ear (e.g., main
receive in the left ear) and decrease it in the other ear (e.g.,
sub receiver in the right ear) or vice versa in either dual Rx
or Diversity mode.

If you are using dual RX mode (only) and have set L - MIX - R to
Ab  Ab, the mix control will change the relative proportion of
each signal in both ears (e.g., go from all main to all sub or
vice versa).

73,
