.Thebehaviourofeach
individualbandcanbechangedtoavarietyofdifferentfiltershapes,includinghighandlowshelves,notch,
andbandpass.ChangingthefiltertypeisachievedbypressingBYPASStobypassthefilterandthen
pressingENTER duringeditinganyparticularband.Formoredetailsaboutthevarioustypesoffilter

Note that 2 bands each will be lost when using 48 dB slope crossover filters, resulting in a maximum of 5
bands of EQ when both high and low pass are set to 48 dB/Octave.
