Before wrapping up a Mackie SRM450 powered speaker I took some
representative DC voltages on the complementary pair power devices of the
bass driver amp, for me and all else, future reference.
-42, -88, -42.8
41.2, 88, 42
What would the circuit type/ class name be, for this sort of biasing?

in comparison for horn side amp, same devices
0, -43, -.55
.55 , 43, 0

**There are only Class A, Class A/B, Class B and Class D amplifiers used in
audio. Anything else is just marketing bull***. What you have is a Class
A/B amp, with a switched rail power supply. Class H, Class G, et al are just
marketing terms.
