I am really struggling getting the MC to output sound on the sub. I went from a old Harmon of 18 years to Emotiva Mc 700 and amp
It was simple set the cross over frequency and make sure the subwoofer is plugged into the pre amp. Well this new unit is not that easy apparently.
I have a Velodyne DLS powered sub that has its own built in cross over and controls. I have played with the built in cross over and volume controls on the sub to no avail. Sub does work!
I was able to confirm using the test tone and room calibration the sub is receiving signal. And when calibrating it out puts like a son of a well you get the idea. The sub only turns on when receiving signal and powers up while playing music so it’s getting something.
I have tried changing the frequency from default 80 to 40 what I had it set to in the past. Nothing.
i have read certain inputs lack the sub channel in the encoding and setting it to all stereo resolved the issue. It does activate all 5 speakers but no thump.
i turned the speakers to large and small just to observe changes. Nope.
the sub did power up and work once while I was changing the frequencies around. Worked perfectly until I powered down the Mc and back up. Sub stopped working again.
i have a long high quality coax cable running the sub.
i have tested Bluetooth and HDMI direct. I noticed a large difference in signal level between HDMI and Bluetooth. I would say 15 db roughly. Not sure if that is related. I know you can adjust the gain in the Mc to increase output but I thought it was odd to have such a large signal level difference between the two.

Is this only with 2 channel or movies as well.

So the test tones confirm that your subwoofer is playing and signal is reliable. Curious when you play a movie 5.1 or PL II say music or movie does the subwoofer output? What trim is the Subwoofer at? It is odd that it is healthy out from the test tone but not so much from the content.

I have PlayStation 4, PVR, android box, and Bluetooth as inputs available. All of them have same result. All stereo seems to work best for two channel inputs like PVR and Bluetooth as otherwise it does not work on all 5.1 channels.
I have since removed the PlayStation from the mix because the Mc appears to not be able to handle HDR. It flickers black on and off. I reached out to support directly on this matter and looks like it just is not caplible of it even though they sell it as HDR 4k.
The difference is signal volumes also concern me. 15-20 is huge difference as far as I am concerned.
Sorry I do not know what you mean by trim settings.

The MC-700 includes six 4k HDMI video inputs, including three that support 4k UHD HDR video – ...this may be the HDR problem, need to find out what 3 can handle it.

The difference in signal could be due to your speaker sensitivity...eg I have Klipsch La Scala ll's with 105db sensitivity running on an XPA-2 Gen3 amp pushing 300w/channel. So my speakers get very loud with only a little volume , since the sub signal is based on the volume control its get very little signal. I had to jack sub signal +15db to get it to run.
Also: set your sub xover to its max frequency eg. highest like 180hz 250hz whatever it is. This allows you to set the cross-over with the MC.
Check the speaker settings on the MC. While I'm not familiar with that model my pre/proc has settings to turn on/off subs, set 2.2 5.1 ect for each separate input.

The 4K issue as far as I am concerned is a lost caused. I have spoken with support and not found a solution other then just bypass the Mc. It appears only current solution is to run 30hz.
The speaker gain is odd between sources but not the root cause of subwoofer problems. The reason I say this is when the one point the sub did start thumping it was to loud and turned down volume slightly on the sub. Worked brilliantly for the hour or two. Litellay powered it back on and stopped working.
I did start a conversation with Emotiva over the extremely poor condition of boxes and treatment of UPS parcels but I would think this is not related. The boxes looked like they where dropped off my roof four times. No internal damage to the actual contents though.

I have never owned an MC-700 but here are two general troubleshooting questions: 1) Did you run Emo-Q? and 2) For what sound mode did you configure the input?

I though I answered both of those already. Yes Emo works and verifies the sub outputs correctly. Test tone also verified this. Sound modes have also been listed in stating that all stereo in two channel environment seems to have best results as it uses all speakers where other encodes do not. There was a thread somewhere on the forums regarding user experience on this matter. |

Sounds like it's working properly then. The subwoofer output is an LFE output. Unless you tell the processor you wish to add the sub into a stereo input there will be no output from the sub as there is no LFE content in stereo. This is how things worked in the UMC-1.

In order to get output to the sub with a stereo source....
You'll have to have the sub set to "yes" on the speaker size menu...
And your main speakers will have to be set to "small"...
(And they you'll have to set a crossover frequency -m or leave it at the default of 80 Hz.)
Then it should work.
The crossover setting on the sub should remain all the way at the top frequency.
And, since your other speakers are very efficient, you'll probably want the volume on the sub set pretty high.

Ah the mysterious, undocumented MC. Another option I have tried that works well for stereo PCM from my PC is to set the mode to stereo and go in and set the DoubleBass to yes. This will allow you to use front channels as large and still have sub boost for stereo listening. If you use Direct, no sub output. If you use stereo and DoubleBass then it works as you desire. Its in the menu under Speaker Setup, Size/Crossover.

Sooo the room EMO keeps resetting and some reason the sub does not output unless room EMO is active. It’s almost like the system has no memory.
I have followed all of the suggestions on here and still having problems. Once I run EMO the sub outputs sound. Pretty much as soon as I turn off the system it looses settings.
this whole setting up the system has not been smooth. I thought by purchasing the lastest and greatest on top of a company that has lots of positive reviews I would be safe from issues. HDR nope. Subwoofer nope.

What firmware are you running on your MC700? If it's not 2.9.2 you may want to update it as see if it corrects your issues. I'm on 2.9.1 and have no problem with sub output or UHD/HDR

It is the lastest firmware. If I has cleared the setting again when I get home in a few days this will become an advance troubleshooting problem.
The only thing I can tie the sub not working correctly is the EMO seems to clear its self when powered down. The unit never actually looses power just standby mode. Amaybe UPS playing bumpercars with myshipment might explain a few things.

Check what mode you are running in. The MC might be set for Direct (in the Modes menu), in which case the EQ is bypasses. You should be able to input PCM and get the sub working in Stereo mode with DoubleBass enabled.

Since my PS is no longer plugged in due to the HDR problems. |

So I have been having issues with sub woofer no longer out putting sounds. I gave up for a long time to the point I forgot about it. Then I started tinkering again. Confirmed sounds output on sub and connections. I googled the problem and realized I had this issue before ages ago...
Test tone nothing. EQ test sound came out of the subwoofer. Then like magic sub woofer started working again. What lead me down this path was the very thread I made a long time ago. I don’t understand what the problem is...
I have always had HDMI issues and feedback problems through the PVR even though I have changed all the cables and the PVR unit still get noise. Even tried different power plugs on separate circuits. Warranty is long expired. Already had the HDMI repaired once which was a 350kms drive to drop off. Oh well guess just be happy I figured out a workaround I guess. Also have issues with pass through doing weird things which is why only one HDMI plug is used now.
