Ok so i have an Integra DTR 40.2 and as dose for a lot of these amps the dang HDMI board died and so i got to looking at this guy and was like (what if i just use the power amp board and build one heck of a 7 channel amp from it).
Now i haven't got to pulling it all part yet but unless someone can point out where to buy a HDMI board I'll just have a big 40lb paperweight and will be forced to just go ahead and make something cool.
While i was looking at it, the amp board is built really conveniently as far as all i need to do is.
(Get a new case and install/do the following)
1. Install a power switch, fuse, power filter and surge protect
2. Install the same old main power transformer that the amp board used
3. Run 7 channels of RCA inputs to the amp board
4. Run 7 channels of speaker connections from the amp board to the new case (banana plug type for me)
5. Ground everything to the case
but here is where i am stumped.....on the amp board there is a 9 pin out for various things and are in the order as followed
Pin-1 VOLH
Pin-2 SEC1H
Pin-3 VPROTECT
Pin-4 IPROTECT
-----------------------------
Pin-5 GND DG
Pin-6 +3.3VMPU
Pin-7 THERMAL1
Pin-8 FANCTRL
Pin-9 12VFAN
I know Pin 5, 6, 7, 8 and 9 go to the fan and thermal system and its independent from everything, so i wouldn't need to hook anything up to those pins.
BUT for pins 1, 2, 3, and 4 i have no idea what i would need to do to get this hooked up right or if i need to hook up anything to it at all so here is where i need help.
what do they mean and what do i need to do to those pins?
I would have uploaded the PDF but its too large for this sights limits
