My board has arrived. Checking connections..

J2 = Hot lead, J1 = Neutral. Earth ground = J25?

Speaker outputs A&B (speaker 1), C&D (speaker 2); B&D are "+“. A&C are “-“ ?

Inputs D-GND-C (channel 1; D&Gnd for SE input)...B-GND-A (channel 2; B&Gnd for SE input)

What are C8 & C9 used for?

Thanks, Pete

Successfully connected and running. Already sounds spacious and deep. Will run on the test speakers for a day then onto the main speakers.

Regards, Pete
