I'm trying to hook up the Polk SurroundBar 360 directly to my receiver without the dvd system (which I don't have).

Does anyone know if the SurroundBar 360 just accepts the line-level speaker signals directly out of a receiver or if it is some digital signal?

So far I ohmed out the pinouts and got the following results (single 8-pin connector):
Pin 1-2: 1.2 ohms
Pin 3-4: ~8 ohms
Pin 5-6: ~8 ohms
Pin 7-8: ~8 ohms

And all other measurements are open circuit (i.e. between Pin 1-4 or 1-7)
So I'm guessing the pin-pairs 3-4, 5-6, 7-8 are 8-ohm speaker connections (left, center, right)? I don't have a clue what Pins 1-2 are for.
Can anyone shed some light?

Update:
Speaker Layout: 8 speakers, 4 on each side.

speakers are paired to the pins:
Speakers 1-2 paired to pin 1-2
Speakers 3-4 paired to pin 3-4
Speakers 5-6 paired to pin 5-6
Speakers 7-8 paired to pin 7-8

Looking at the picture I would expect 7 distinct channels, not just 3(Left/Right/Center). So with an 8 pin connector there's probably a common ground and the 7 channels. You can use a 9volt battery to identify each speaker to each connection. Just google 9v speaker test for info.

Also, is that the correct picture for your soundbar?

you are correct, the picture is wrong (I'll remove it).
I opened up the speaker grill and there are 8 cones, 4 on the left and 4 on the right.
I tested the 8-pin connection with a 9-volt as well as my amp and I got the following:
Pin 1-2: no sound, had to REALLY crank the amp up to hear the sound out of speakers 1 and 2 and gome a bit of distortion along with it.
Pin 3-4: sound out of speakers 3-4
Pin 5-6: sound out of speakers 5-6
Pin 7-8: sound out of speakers 7-8

seems like the pins are direct inputs to paired speakers.
I have a hunch that speakers 1-2 (and pins 1-2) are toasted. What could cause the impedance of the speakers to go from 8ohms to ~1.2ohms?

Hi I realize this thread is 1 1/2 years old, however, i have just gotten the surroundbar as a hand me down and still in the box. I dont have the dvd/receiver. I was wondering if you could help me out, im not real savvy when it comes to electronics but i can take direction well. My goal is to hook the surrondbar to a different receiver for use. I understand the pin layout, i think, but what is used as a ground? In the plug itself, if i pull the plug off is the ground going to be "within each" pin? If you have any info on how i could do this i would greatly appreciate any and all help you can provide on this subject. sorry if all this is hard to understand... thanks

did you ever find a solution? My receiver stopped working, I'd like to use the speaker if I could.

Did anybody ever get this to work with a different receiver (amp)? I have one of these and the console is dying, would love to pair this bar to a new receiver.

This old soundbar sounds very good with a Yamaha RX-V375. Works well, even added rear channel speakers.
