Default Arjen Helder TA2020 6ch amp...

I've been trying to work out how to wire up my 6ch TA2020 and unfortunately Arjen has not got back to me with a schematic (even though I've asked for it several times...)

Can anyone take a look at this amp and tell me how you think the input wiring works.

eBay - The UK's Online Marketplace

The speaker connections are on the other side of the heatsink (not visible in the photos)

The inputs are on that ribbon cable but they are not labled on the board. I'd expect 3 inputs per channel pair L+R+G - so a total of 9. The ribbon cable has 10 strands - a group of 7 and then a group of three a little back from the others.

Help greatly appreciated.

Looks like a nice amp. Did yours come with the white ribbon cable as in the picture? Am guessing that this provides the inputs and the red and black cables are +V power and ground. But Arjen Helder will have to give the final say. Looks ike the TA2020 can go up to 14V for 4 ohms and 13V for 8 ohms:

Yeah the cable is soldered in. It's a lovely board (for 0.99!) and Arjen shipped it with a 6 channel volume pot which I wasn't expecting.

Just wish I knew the intended wiring...

Still no response from Arjen....

that's 4 ebay contacts and 2 emails directly to helderhifi that have been ignored... not what I expected from Arjen.
