hey guys, just now i tried the pro EQ,
what i notice:
1. low : there's a reduce for the low frequency.
2. High and mid : there's a slight gain reduce.
the change at the low frequency makes the humming (surrounding sound) became less,
the bass instrument and the punch still the same, but the lower frequency reduced (i believe its called sub low. am i right?).
because of it, the sound become more tight with a less humming background.
and by generating a tighter sound may emphasis vocal, or other instrument.
it makes the music become more accurate.
sorry for my bad english. >.<
