Different HDMI input? OK, I'll try it. Thanks.
Another question, please - "Midnight mode," (or whatever it's called) - advantages / disadvantages?
I think it may be the thing for when my wife wants to watch with me - She's explosion-averse (hurts her ears). I understand the concept of compressed dynamic range, but my question is: Does the compressed mode apply itself only to movies, or will it also compress music coming in on the same input? And the follow-up, "Can I assign the compression mode ONLY to one input, or do I have to turn it on and off every time I want to switch between movies & music?"
Thanks - Boom

Not just any input, but rather 4-6. 1-3 are 4k; 4-6 are 1080, and this will just be to see if you get dropouts on the 1080 inputs. I'm guessing the Oppo's audio out won't have HDCP handshaking behavior, or at least hopefully not for non-4k Blurays.

Audio only goes into HDMI #1 input on the MC-700. The MC-700's #1 HDMI output goes to input #4 of the Samsung. The OSD issue would be whether your TV is in 1080 mode or not (4k). You could try the Audio going to HDMI 4-6 for your streaming and non-4k movies, just to see if you get any dropouts there. My guess is the dropouts are tied to the 4k capable chips (inputs 1-3). Played a movie last night from an oppo with a new expensive hdmi ( on port 6).- no dropouts. Then watched tv through a cable box on port 5 ( old hdmi) frequent audio drop out. Any reccomendationn for budget hdmi upgrade- does this sound like a heat sink would help? |

My latest budget HDMI cables came from two sources:
1. monoprice.com has premium, certified, high-speed HDMI cables for less than $10.
2. I caught the local Radio Shack during their "last 5-days" sale & bought their top-of-the-line HDMI cables for 80% off.
Both work perfectly with 4K.

Well, i decided to upgrade my AppleTV gen2 and installed a ATV4 last night to my MC-700. As Donny was saying there is indeed a lot of popping and re-sync'ing going on. I'm not sure why, since the ATV2 was actually pretty stable (sonically). Then i starting doing a search on the proper audio settings and wound up feeling worse about the whole situation. I think i'll experiment a bit and see which audio sounds the best. I watched a bit of NetFlix last night with the "Dolby Digital" setting on (as opposed to "Best Quality Available"). ATV4 is definitely fast though. Gotta love that wireless AC. I order some certified hdmi cables. I'll let you know if that fixes the problem. I also switched to Dolby Digital hoping that would fix the problem. Seem that anytime I pause something in an app the audio drops out. When switch from an app to the main menu the audio also drops out. New hdmi cables didn't make a difference. At this point I am super disappointed in my purchase of the MC700. |

Hi donnyb - I don't get any popping at all from my MC-700. Call Emotiva - maybe you got a defect? I note also that after a week, my audio dropouts are decreasing in frequency and in duration. When my processor was new, the dropouts would be noticeable and audible, but now I have to listen REALLY closely to notice any at all - and they're happening less frequently. No idea why, but I'm definitely listening for dropouts, so it isn't just that I've grown accustomed to them. Cheers - Boomzilla |

WHOA!!! That's a POP! No - my MC-700 has never done anything remotely like that.

WHOA!!! That's a POP! No - my MC-700 has never done anything remotely like that. It's quite startling to say the lease. I believe it's caused from the audio dropping out in the AppleTV gen 4 and reengaging when switching apps. Since the AppleTV is the center of our media hub with Hulu, Netflix, DirectTV now, HBO, and Plex. The noise in the video I pen pointed to the theme music plex plays. I turned it off and it seem to stop. But we are still having problems during playback when pausing, fast-forwarding, and rewinding. |

Hi again, donnyb - From what you're saying, this sounds like an Apple-TV issue rather than an MC-700 one? |

I've never had that kind of sound either. Sorry to hear you're still having that problem, donnyb.

Yep Donny,
that's exactly what I'm getting.
Usually when i'm relaxed. Then "BZZZTBZTTZ", and it makes me bolt upright, scaring the hell out of my wife.
Hopefully, it's not doing any permanent damage.
And like I said, it was never a problem with the ATV2.
SO, that makes me believe it's an apple (gen 4) issue as this is the only device that exhibits this particular behaviour.
I was hoping better cables would help out.
It's disappointing that it wasn't a quick fix.

At this point I am super disappointed in my purchase of the MC700. This statement makes no sense at all, since you stated the problem started when you added the AppleTV 4, and that the AppleTV 2 worked fine. Perhaps you should be more disappointed in Apple than Emotiva. |

I have an ATV4 connected to my XMC-1 and it's dead silent.
Strange.
Has anyone contacted either/or Apple/Emotiva directly?

Nope. haven't contacted Apple or Emotiva yet.
Not sure about Donny.
Thrill is correct though, Donny. You shouldn't be upset with the MC-700. I think the fault my lie with apple.
Here's their tutorial so far:
i'll try some of these later.
one trick may, indeed, be just to turn off menu clicks.
right?
For me, that's when it happens the most.
and USUALLY, in between streams, it's just a half-second of silence until the MC-700 picks up the stream and begins to decode it properly.
Not many pops. but the menus are a different story.

I am getting the same "BZZZTBZTTZ" sound as shown in the video. It is not just an Apple issue. Mine happens most often when using an Xbox360.
It happens every single time the Xbox switches from 2 channel PCM 48KHz to Dolby digital 5.1. In fact, I can go into the Xbox options screen and just toggle dolby on and off and it will do it every time.
I reported this issue to Emotiva support hoping they can fix it with a firmware update. Can you guys check and see if the AppleTV is also using Dolby, or perhaps switching from one mode to another when you get the sound?
Edit: Just watched the video again and I noticed that the OSD pops up and says Dolby Digital right after the sound happens.
I should also mention that this happens with brand new BJC series FE cables from source to MC700 and from MC700 to my TV

That is exactly the noise you get when the input stream is DD, or DTS for that matter, the processor is expecting PCM and hasn't muted fast enough while it engages the compressed audio codec. Try playing a DTS CD via analogue and you'd hear the same noise.

Yes, now i'm tending to agree.
I was doing some upgrading on my android box last night, and noticed that when I switched streams from PCM 48 to DD5.1 i got the same noise.
and as for the apple, yes it's attempting to use a DD5.1 dtream as well, so maybe its something with the timings.
hopefully Keith checks in soon...

This issue sounds like it's between a rock and a hard place. If the MC-700 mutes the sound until the change in incoming bitstream is recognized and re-locked, then there will be a silence between switching sound modes. That'll cause complaints.
OTOH, if the MC-700 doesn't mute the sound while the transition occurs, then the clicks will continue - again causing complaints.
But the bigger question is: Who should be responsible for fixing this issue? Apparently, some sources don't trigger this problem. Others do. Should it be the responsibility of the source manufacturer (Apple, Android, etc.) to eliminate the cause of the issue, or should it be Emotiva's responsibility to eliminate the consequence?
I'd vote that the device that causes the problem be the thing that needs fixing.
Boom
