in an ambisonic listening system, ambdec's job is to *render* the
b-format signal as appropriate for your speaker layout.
hence, there will only be a single ambdec instance and configuration for
any given speaker layout.

i'm not sure i understand what you do with your 60 stereo pairs, but you
will probably want to mix them into a b-format master bus, using an
ambisonic stereo panner. listen closely for comb filtering, though, if
you ever end up putting the two signals of a stereo pair very close
together. coincident stereo works best here.
