Chip amp hookup

[argonrepublic]

I have a couple of STK4044 modules. I am about to attempt firing them up. The PCB has labels -VDC, +VDC, Gnd, Gnd, Gnd, +sig, +sig, HP, HP.
I am assuming, that sig+ is the input for each respective channel and HP is the output power from the module. Are all 3 grounds shared in a chip amp like this? Can I feed these modules with a preamp? I have a transformer, rectifier, 6800uF 56Volt capacitors and 500ohm resistors to power these up. Is there anything else I need?
The picture is not very large but may be readable.

Just a minute.... not very large How big did you want it.

I think you need to do some checks before firing it up. The speaker output will go to the coils (+S I would have said, just from you asking and me looking) so thats total uncertainty. Have a measure and refer to the data shhet for the IC to check the inputs, but once the speaker out is determined the other has to be input by default.

My scan didn't work out so well. I was hoping it would be more legible. I will take some time and study the datasheet.
Thanks

I got caught attaching that picture... the site went slow... if you can't see it refresh the page

Your picture is massive

Looks like pin 3 is the only ground to be connected.
