Default Question about Lm4780 kit

Pardon my ignorance, but I'm very new at all of this. I want to build a chip amp(s) to use in a bi-amp setup. I'm a tad confused about the dual mono 4780 amp available at I'm thinking that "dual mono" means two chips, each bridged. Is this correct?

Thanks in advance for the info.

Dual mono simply means 2 mono amps with individual power supplies.

Each amp board has both channels of the LM4780 paralleled making it a mono board.

If you share a common power supply then it is a "stereo" configuration as it is two channels sharing some common circuitry.

If you use two power supplies with two traffos then you have 2 distinct mono amplifiers, thus "dual mono".

I hope that helps clear it up.

BTW Brians LM4780 kit is the bomb. Enjoy it. I have built 6 of them.
