Much the same as my 5 channel version but with a 25-0-25 500va as no bridging going on here. Using 2 x 8 way Speakons for the speakers to connect to my Linkwitz Orion's
Excellent. I really like the layout of your amps. You will find that you will get better performance (lower THD hum and noise etc) if we take the 0v -speaker wire from the provided pad holes on each amp on the PCB ground plane. This is due to the star ground being before the capacitor bank which is on the 8PAKAMP PCB. So the current in the 0v power wire going to the PCB modulates. So the smoothest best place to take the 0v is on the PCB where the cap bank 0v ground plane is. This would make your star ground a lot smaller as well.
About to use a lot of these 8PAKAMP'S in a new 1000 seater theater for a full dipole speaker system that is huge.
