I started to hear slight distortion in the high frequencies and vocals about six weeks ago from any source I was using.now it’s gotten much worse.I’ve tried restarting the rmc many times and I changed all of the cables.
Is there anything I can try ? unplugging it didn’t help at all.
It’s under warranty so I’m hoping emotiva will work with me on this. are they usually willing to do repairs if needed?

The owners thread is for all things G3P (RMC1/L & XMC-2), a new thread is started when there’s a major firmware release (1.x, 2.x, 3.x, etc), but the discussion is not limited to firmware. I’m just an unofficial sheepherder who try’s to keep discussions in the right place, and since you mentioned an Emotiva warranty I assumed it regarded your RMC-1L, so the thread I linked is the right place to ask your initial question. For now I’d say maybe (you could add your current firmware when you post there). |

To verify the RMC-1L is the source of the problem, take it out of the equation for comparison.
Connect the OPPO directly to the amps and use the same music disc as was used when the OPPO was connected to the RMC-1L and compare. The OPPO is capable of being used this way. I've used mine connected directly to amps many times.
Other questions:
Is Dirac involved?
Does the distortion happen with multi-channel or two channel music? . . . or both?
Is the distortion only when playing music, or HT also?

Ok,thanks guys I didn’t realize I was in the wrong thread.
I will try the oppo to amp. Distortion is with anything I play. Blu ray audio has super loud vocals in the center and awful sound in the other channels. No Dirac.

I'll respectfully disagree with the directions to put all discussions in the mega-thread. This is an odd enough problem that it's nice to have an option to search for it, which isn't necessarily possible if it's one of thousands of posts in a single thread. So dreams, I think you should keep your discussion open here, unless you happen to find a firmware update resolves it for you. |

Thanks,I was starting to question my etiquette.when post on an existing thread it’s seems I’m interrupting a different discussion.

When the rmc is working normally it definitely sounds better than the oppo though. |

Next would be to reconnect the RMC-1L, but only with the same channels you used with the OPPO direct to amp test. If distortion occurs, then the next step would be a Factory Reset. |

I just connected oppo balanced out to rmc balanced in and the sound was not as clear as oppo to amp.
I did a factory reset two days ago but nothing changed.
Blu ray audio such as allman brothers dts hd or yellow brick road dts hd used to sound amazing,now it’s a mess.

Then you should submit a Support Ticket.

Then you should submit a Support Ticket. After 5 months I’m still unable to use my system because of distortion so Im looking for any suggestions. I sent my Rmc1l to emotiva,they tested it and found nothing wrong. It sounds very bad regardless of what source I’m using. My system sounds ok at low volume but when I turn it up it sounds like it’s struggling to play louder. I don’t have another pair of decent speakers to try so I’m pretty limited in my troubleshooting. Does this sound like a speaker problem or the xmc-2 amp?? Is there any chance all of my xlr cables are bad? They’re all the same brand. (around $20 each) Could dirty AC power sound this bad? beyond frustrated,I wish I knew what component needs replacing. |

I don’t have another pair of decent speakers to try so I’m pretty limited in my troubleshooting. 1. Does this sound like a speaker problem or the xmc-2 amp?? 2. Is there any chance all of my xlr cables are bad? 3. Could dirty AC power sound this bad? 1. Difficult to say at this point. 2. Highly doubtful, but easy to check with a multimeter. Check continuity between pins. If there is any shorting going on, continuity will aid in finding it, along with Resistance, which should show infinite - no connection. 3. No. I say no because it's so far down the list, but is it "possible"? If it were possible, then it would sound bad all the time on every channel in every combination of components. Basic troubleshooting 101 says to reduce the system to it's simplest setup and still get sound. Disconnect everything from everything. No speakers should be connected to any amp, no HDMI cables connected, no interconnects connected, no power cables, nuthin'. You mentioned that the Center speaker sounded fine, so use it for the test below. Use the Tuner in the XMC-2 as a source. Connect one interconnect from XMC-2 Center Channel Output to an amplifier input channel. Connect the Center speaker to that amplifier's output channel. So now all that's connected together are: XMC-2>>Amp>>Speaker. Pick a radio station, music or talk, change the Audio Mode to ALL STEREO and see how it sounds. If it sounds fine then connect the interconnect cable to a different XMC-2 output channel, Left or Right, and see if the sound is same/worse. etc, etc, etc. |

I’ve swapped my xpa2 amp with my xpa3 amp and used my surrounds as mains and still sounds terrible. Could it be RFI or EMI? Is a conditioner worth a try? streaming music and watching Blu-ray regardless of what surround mode I’m using are all distorted. |

If you've got RFI or EMI causing a problem like you describe, then I would think problems could be heard using headphones. Think about a basic setup that uses the least amount of connections. Absolute minimum. Maybe try an extension cord and plug into a circuit from a different room. Do you have a multimeter to check the outlet with? Not just AC voltage, but also check to see if any DC voltage is present. Connect one test lead to Ground and use the other lead to check Load (Hot) and Common. If there is more than a few volts AC between Ground and Common, that's a problem. I've seen as much as 60 Volts between Ground and Common which led to discovering that a wire nut had gotten loose elsewhere. |

It sure sounds to me as you have described it so far, that you’ve got a developing problem in your amplifier. As you said, it was a slight problem with the high frequencies and developing into something worse as time has been going on. Any chance you can borrow an amplifier from somebody and give it a test run, if not, I would recommend looking to the amplifier to be serviced |
