Minor main display bug. Under input setup I used HDMI4 for video and Optical3 for audio.View AttachmentThe XMC-1 use Optical3 as input, no HDMI4 audio, but the display still show A: HDMI4 as the input.
View Attachment I have a similar issue... HDMI-7 set for audio from balanced but display says HDMI-7 for both Audio and Video, but the audio is coming from BAL input. Also my OSD setup menu is just showing filled in blue blocks when I move around and its in an odd place on the screen too EDIT Interestingly after a full shutdown and on again its displaying the Audio as Balanced now. and the menu OSD is looking OK again  Looks like the real world is finding a fair amount of bugs. I wonder if they have been introduced at the V1.1 HQ pre ship update or they are in the V1.0 firmware too... any beta testers still on the V1.0? |

Not able to play 192K audio. The audio plays @ 96K through the HDMI.

My issue with the HDMI audio was with a WD media player. Same WD media player worked fine with the UMC-1 playing 192k music.

Emo is aware of this and working on it does this refer to the USB issue? its also an issue for PC as well not just MACs. it is posted at the start of this thread in the running list there. no need to post know issues unless there is some new information or complication. I believe this is true of all inputs not just the usb input |

When the all stereo mode is selected the volume level for all the seven speakers drop approx by the half and the subwoofer channel volume jump higher approx by the twice.
I don't think it is supposed to play this way.
OK, here is my complete observation on all stereo mode working with many configuration input:
With all the two channels input CD player via analog, via optical, via AES/EBU, demonstrate the problem mentioned.
Tuner also demonstrate the problem (it is also 2 ch.).
With the HDMI inputs when the source signal is pcm2.0 the problem is present, but when the signal is PCM5.1 the all stereo mode working normally, no volume drop on the seven speakers and also no subwoofer volume jump higher.
Conclusion the problem appear on 2 ch source but not on HDMI multi ch 5 and more.

CONFIRMING LOW AUDIO LEVELS USING STANDBY PASS-THRU
Pass through HDMI audio levels are about 50% lower than normal.
CONFIRMING ALL STEREO MODE AUDIO LEVELS ATTENUATED, using TUNER input.
Although I haven't noticed the reported Subwoofer volume rise.
FIRMWARE V1.1 installed is current shipping version. XMC-1 was received 8/19, shipped 8/14.
Anecdote - the unit seems to run very warm.
Last night I had the XMC-1 declare that my TV thru HDMI had lost CP verification and I lost video, on both XMC HDMI outputs.
A couple hours shutdown and all was restored.
Aside from some shakedown and User setup confusion, most everything else is good so far.
Sound quality is outstanding.
This is far from a UMC experience.

If you get a glitch in the display screen whether it is on the OLED or the OSD that just means something has gotten stuck in the buffer.
Simply save your settings on a USB drive, do a load default and reload your settings. This will resolve your issue.

If so, should this be SOP after a firmware upgrade? |

As a side note, the Xmc-1 does 192K with all inputs, except USB. Most of our digital test during final assembly is done at 192K.
So please check your source unit to make sure that is what it outputting.

RE: PASS-THRU HDMI AUDIO VOLUME IN STANDBY MODE FOLLOWS THE LAST XMC VOLUME SETTING
Audio levels are reduced from norm when in the XMC is in Pass-Thru Mode.
However, I have discovered that pass-thru audio volume follows the last XMC volume setting prior to engaging Standby Mode.
If the XMC volume was middle to low, pass-thru HDMI audio is severely low.
If the XMC volume was very high, then pass-thru HDMI audio is nearly normal. But still somewhat reduced.
Apparently, the XMC volume setting represents the limit of what pass-thru mode allows.

Older amp trigger dropping when changing inputs/modes/set top channels (known issue now and fix is in the system but not released - probably will come with the Dirac update), workaround with DIY modded cable or use manual power button for affected amps. LV This is due to current limiting. The trigger outputs are limited to 100mA of current. On some amps there is a capacitor in line with the amp that when starting up will draw more than the 100mA limit and the output get will momentarily shut off to protect itself from burn out. Putting a low value resistor in line with the trigger will limit the current draw as the capacitor charges.I can confirm that the "modified" trigger cable (which was graciously supplied by Emotiva) does fix the trigger issue with my XPA-1s. My thanks goes out to Damon and all involved at Emotiva…..  |

Anyone have an exact value or a range for this resistor? Another fix was a 1n4148 diode and a capacitor, also from Emotiva support. Which is it to be?

Doc did you happen to measure the resistance of the modded cable? I would like to not have to experiment too much with the values I have laying around if possible. Its bad enough she have to have mess with at all never mind stubble around with this value or that. Emotiva really needs to detail these workaround properly. Most of us are using Emotiva XPA or UPA series amps so this is important to provide a vale. Im not going to wait for them to ship out a cable or 3 that will take weeks to get to me.

The only model you will need this on is the UPA-700 and anything between 33 and 47 ohm will do just fine. Would you like for me to give you a schematic for a bullet proof trigger cable? Lonnie |

So please check your source unit to make sure that is what it outputting. Lonnie Lonnie, I am confused. Why is USB different? Your XMC-1 spec for digital inputs says: "1 – USB Type B digital audio (“USB DAC” input; up to 24/192, UAC2, using CM6631A)" The USB Type A inputs on the front panel and on the back are only for firmware updates: "2 – USB Type A digital data (for firmware updates and future enhancements)" Unless of course you have made a change and we can read audio files from a USB drive in those Type A inputs? A separate question. How do you get a DSD audio file (not a SACD) to play through the XMC-1 on HDMI. (Page 6 of the Preliminary Manual). I am sorry for any confusion here, but you can use the USB for streaming right now and we are finishing up the code to read audio files from a USB stick as well. Their is something up with the code on the USB streaming and it is currently only running up to 96K, but we will have that worked out very soon. All the other digital inputs will easily do 24/192.
