I am still having the problem with ARC. Does not matter if I power on my TV first or my RMC-1, In order to get ARC to work I have to go to another input, I go to menu, then right arrow to HDMIARC, up arrow, then down arrow back to HDMIARC and then I get audio Is ARC your default RMC-1 power-up input selection? Have you tried making ARC a preset on the remote and given that try? FW 1.10 has corrected my ARC issues. I have a Samsung Q80R and ARC would not work prior to FW 1.10. My RMC-1 default power up is my DAC on Analog 1. I do not have a preset for ARC, so I always have to cycle through inputs to 'switch' to ARC and I have had no problems. |

Still having a problem with HDMI CEC Volume. I've tried disconnecting the TV and powering down the RMC-1 on the rear switch, this would clear the issue with FW1.9, upon power up it used to re-enable CEC Volume commands from the TV. Now it just doesn't work, CEC Power does though.

I’ve started doing some testing of the Neural X issues in my 5.1.2(top middle) setup. An interesting test I’ve found is my old Eagles Hell Freezes Over DVD with DTS 5.1 version of Seven Bridges Road which in original 5.1 decoding places each singer at a separate channel. Turn on the up mixer and some voices end up on heights on the other side. Interesting. Looking for some reviews info on Neural experiences online with other processors I ran across this lengthy comparison from a few years ago. Some of the authors testing/conclusions with pink noise were enlightening. See what you think. rantingsofamadaudiophile.wordpress.com/2017/05/20/dtsx-vs-dolby-atmos-part-ii-dolby-surround-vs-dts-neuralx/ |

So...I've got a significant issue. I think it's the XMC-2, but I also added 4 Atmos speakers (Airmotv A1s), an amp (BasX A-500), and 4 XLC to RCA adapters, so I suppose it's possible something else is to blame. As soon as I turn everything on, I get a loud whine coming from my 4 new Atmos speakers.
Here's why I think the problem is related to the XMC-2. Some of you may recall, when I first got the XMC-2, I noticed a high pitch whining sound coming from the chassis. The high pitch whine starts off at one pitch when you first turn on the XMC-2, and then changes slightly when the unit is done initializing. After speaking to tech support, we determined that it's probably to be expected in a room as quiet as mine.
To mitigate the problem I rearranged my shelving so the XMC-2 wasn't at ear level, and there was a buffer between it and my head. Unfortunately, the exact same behavior is still happening, expect it's being amplified by the A500, and output over the 4 top speakers. It's impossible to watch anything, unfortunately.
Some details/things I've tried:
1. Turning off the amp stops the problem (obviously).
2. Turning off the XMC-2 stops the problem (not surprising).
3. Volume control on the XMC-2 makes no difference to the tone or volume of the whine.
4. Turning off the front OLED on the XMC-2 makes no difference.
5. The problem only occurs when 2 or more unbalanced cables are connected. It doesn't matter which two. As soon as a second one of the speakers is connected, the problem occurs. I should point out that I also have an unbalanced sub out, but that's a non-factor.
6. I tried using different cables, but the problem persists.
7. The theater is on a dedicated circuit, so it's not cause by other equipment like the refrigerator or HVAC.
Things I haven't been able to try:
1. Switching out the XLR to RCA adapter, as I don't have any spares to swap out.
2. A different power amplifier. Unfortunately my other speakers are all powered, so I don't have a spare amp to try.
3. Calling Emotiva, since I didn't get the speaker delivery until after they had closed.
Any suggestions for other things I could try?

Especially Joe Walsh in the Left Surround Channel! It has each of the five singers singing a different harmony (Don Felder's bass vocal is inhuman when you listen to it up close!) and each are isolated to one of the 5.1 channels so it is like sitting in the middle of a circle with them. There is some light acoustic guitar in the front channels, and because it is a live recording, some very faint traces of crosstalk where each singers mic has picked up audio (vocal and acoustic guitar) from the singer next to them. This is one of the first tracks I used which highlighted to me that the Neural:X is doing more than changing the volume and how I tracked down that Neural:X was being incorrectly engaged with the bi-amp setting enabled |

I went ahead and ordered 4 (hopefully) better quality XLR to RCA cables from Guitar Center. I hope to be able to pick it up in store tomorrow to test it out. We'll see. I'm skeptical that it'll make a difference, but it doesn't hurt to try. Fingers crossed, I guess.

With correctly wired adapters which are specifically intended for use in a “balanced” audio system (not a microphone), pin 3 should not be shorted to ground, but rather should be left “floating”. If you can access the wiring inside of the XLR housing, see if there’s a jumper connecting pins 1 and 3. If there is, snip the jumper between the two pins and remove it. |

The ones I have seen are not wired with jumpers but simply pins 1 and 3 are soldered together in the RCA plug. Nevertheless the pin 3 wire can be snipped and folded out of harms way. |

That's some very shoddy workmanship. |

That's some very shoddy workmanship. Aside from the jumper, is there a wire connected to pin 3..? If so, break that connection too. As jonstatt pointed out, who knows what they’ve done at the RCA side of the adapter. In a properly constructed adapter, pin 1 should connect to the RCA ring (typically using the cable shield) and pin 2 should connect to the RCA tip. Pin 3 of the XLR side should not be used at all. |

So....if pins 1 and 3 are not floating....what does that do to your sound/system? Does it prevent it from working? In that scenario, no pins are "floating". The inverted signal is being sent to ground (shorted). The correct way to "unbalance" the cable is to connect the non-inverted signal (pin 2) to the RCA tip and the ground (pin 1) to the RCA ring. You do lose the 6db "boost", but that is easily rectified by readjusting the output levels. |

That's some very shoddy workmanship. Hopefully I read everything in the thread. I have had ground loop problems in my room before and having all balanced connections solved that. I had a similar issue recently when connecting a new pair of speakers using adapters. I had a whine only through those speakers. I got a transformer-type adapter to convert from Balanced to unbalanced and the whine went away. But I saw that you said your system is on one dedicated circuit so I thought ground loop would be unlikely... but still, this solution may work for you. So then I added a pair of powered rear surrounds that were on loan from a friend. I ran RCA cables to them using the same connector adapters I had used before. No whine from the speakers. But, they were plugged into a different circuit. artproaudio.com/product/dti-dual-transformer-isolator/ |

There is no value in stressing the output stage. - Rich |

Made with Neutrik connectors for XLR and Canare or Belden cable. Custom made, great prices and beautifully built. Confirmed that they wire the same way Emotiva does. No affiliation.....just a happy customer. |

Yep... because the new Emotiva cables are wired ideally... It is not a good idea to drive voltage into ground. Basically, it wont happen so it stresses the system. Do not connect the positive and negative pins together. - Rich |

Tried The Dark Knight.. Huge difference between Surround and Neural:X. Lower volume and ”muddier” sound
with Neural:X. The volume issue can be fixed with increasing the volume but the muddier sound will never go away.
But I don’t have the missing center or surrounds. The complete surround is there for me anyway..
Again probably wouldn’t notice this for most movies without switching between them. Why some movies have
a clear difference in volume is strange.
Then changed the speakers.. Activated my top fronts and top rears, deactivated my surround backs.
All the Neural:X issues are gone.. The sound volume and muddiness is all gone.
Tried to change back to 7.2 setup from the 5.2.4.. Muddiness and lower volume is back..
Then changed to my normal setup 7.2.4, Neural:X then sounded just fine.
Then changed my tops to heights and the muddy lower sound is back.
Clearly some kind of bug when no top speakers are used.
