Ahhh, I remember the days. I've since moved on to HEOS. The Amp, Link and Drive all have dual mono output. Just saying...

All I see on the back panel are left and right outputs. Are you able to sum the channels internally?

You can select stereo or dual mono in the settings menu. Comes in handy occasionally

Great feature. Are you able to point HEOS to a shared folder yet?

Sure, any phone or tablet on the network, any PC, hard drive, NAS, thumb drive, whatever you need.

Tom, could you point out where you are finding this "setting" on the HEOS Amp and the HEOS Link. I have setup both, and am unable to find this option.

This thread made me stop on a job yesterday. Client has a Parasound P3 and A31. He wanted to integrate a subwoofer. Only cable ran was a single rg59. I recalled this thread and contacted parasound to find out what they would recommend. They liked the edcor piece better than the monacor due to its input impedance. But they also informed me that I could use a Y adapter to combine the left and right outputs from the preamp with no worry of damaging anything. They told me it would force the P3 to output mono...must be some circuitry in there to do this. He was not sure if it also forced the xlr outputs to mono. It did not. I just threw a Y cable in and hooked up the amp with xlr cables and called it good.

On the music tab, click settings in the top left corner, my devices, select the device, output mode, select stereo or dual mono

Crazy! I do not have a Output Mode on either of mine? Maybe mine are early production runs? This would be a nice option to have, especially for doing outside audio.

If you're centered between the speakers, any music will tell you that it's working, or not. The sound will always seem to be coming from a small area between the speakers and nothing will seem to be coming from either of them. There will be no separation between the channels.

No worry of damaging anything on the subwoofer, yes. No worry of damaging anything on the preamp, probably. But if the chosen stereo output is not buffered from the main output, a Y cable will turn the main output into mono.


As I understand this, it forces the P3 output to mono by mixing the two channels together! It sounds like the connection changes something inherent in the signal, but no, the two channels are just connected together.


This is exactly what I was talking about. He was sure that one set of outputs would be mixed to mono but was not sure if the XLR outputs are buffered from those other outputs.


Lucky you. I like to be a step ahead of luck if I can be. Frinstance, what if he decides to change to a different game but wire it up the same way, and that different game's outputs are not buffered? He won't be able to just connect the new piece because you didn't do the most technically proper installation now.


highfigh, your test will indeed work, but it depends on the speakers being in phase. While it's unlikely that they won't be, the other methods of testing don't have that limitation.

It's not good to create a test setup that requires that you run a test of the condition before you can run the test itself.

Well this is why I contacted the manufacturer for their recommendation prior to hooking anything up. If he had said not to do it, I would have immediately ordered the Edcor piece and used it. The only lucky thing was that the XLR outputs remain stereo when you combine the L and R RCA outputs. Luck is fine with me when it works in my favor. :)

The manufacturer's advice, as you presented it, doesn't cover you if a new product's main outs, or even the one you just put in, are made mono by the Y. "He was not sure if it forced the XLR outputs to mono." That's the sentence that means you should use the Edcor piece. He wasn't sure, and you're not sure about the next product that will go there.
