The subwoofer can't be much increased in the MRX and in the setup of the subwoofer the volumelevel is 90%
Thank you, your sub should be capable of putting
Out a lot more volume than it is now.

Couple of things..
1) is your listening area very large???
Large areas can be hard for a single sub to
Energize. Report back on size off room. Don't
Forget the ceiling height.
2) how far away is the subwoofer from your listening
Position? (Same place as ARC microphone)
Did you remember to enter the speaker&sub distance
Into the MRX?

Finally I see that the sub has a very extensive DSP
Menu which allows A LOT of control over the sub's
Outputs, frequencies, boosts and cut offs.

Much more than I am used to dealing with!

I suggest that you disable all of these settings.
Perhaps a reset to factory defaults?

We want to start over with the sub just in the factory
Default mode. No processing or adjusting of the signals.

If we can't get the output levels up higher then there
MAY be a possibility that the sub is defective.

Thanks for your help, much appreciated.
My room is fairly small. The listening area is about 12x12 feet with one open corner. Total room is 25 x 15 feet. Hight is about 8 feet.

Distance subwoofer to LP is 10 feet. Front speakers and centre also at 10 feet and the surround at 3 feet.
Distances in MXR are ok

When using LFE, most of the filtering will be bypassed.
All other dsp shut off
Sub back to factory default (2x)
Nightmode not working.

One extra note: using the internal amp testtones after using ARC all speakers are around 72dB. Subwoofer level then is about 80dB. So using the intrrnal testtone the sub is much louder?

I hope you will understand what I am trying to say here. My english is not very well I am affraid.

I understand you just fine! I'm a bit confused what to do
Next. I see 2 options.

1) if possible take sub to dealer to be tested on another
AVR. Or if you can test a new subwoofer of the same
Make and model to test on the MRX.
2) see if you can bring home a different sub to test.
Or borrow a sub from a friend to test in your system.

If a different sub does the same thing it maybe the MRX.
If a different sub plays louder volume then your Monitor
Sub may be defective.

I think you have a good quality sub with the Monitor. It should
Be performing MUCH better than it is. Your room is not too
Big and you are not that far away either.

Something is not right. Not sure what else to try...
Maybe a factory reset of the MRX is needed??

You have some great ideas sir, thanks you very much.
Tomorrow I will try another receiver. My neighbour has a Denon 4311 so I will ask him to help me testing the sub.
A factory reset of the MRX is the second thing I will try
Last thing is get another subwoofer to see if my sub has a problem.

What would be a normal level for this subwoofer? About 75dB after ARC?

I come back when I have all the answers.
Thanks again


What if I just raise the volume of the sub from 90 to 100%? The sub has a digital amp. Would that be a problem?
Another possibility is raising the LFE level in the MRX from +6 to +10 or 12
Just some thoughts

75db is a good starting point. Your sub should be able
To hit well above 95 db easily. Especially with the level
On the sub itself turned up so high(you said 90%?)

I have a very similar sealed 12inch sub with a 300 watt
Amp and had to turn in Down to 35% because the level
Was too high for ARC! My room is a bit larger than yours too.

It would be a good idea to take your sub over to your
Neighbors and hook it up to his Denon. Shouldn't
Take very long to test it out!

I look forward to hearing back from you on your problem,

Like I said that is a pretty good sub you have,it should
Be performing much better!

Regarding your additional paragraph..
You should not have to turn the gain
On the sub up too 100% AND increase
The LFE level in the MRX to max to get
Good results with that sub.

My sub gain is at 35% and ARC set the LFE
To negative 6!

If you want to try it though go ahead, but
I think something is wrong.

Some good news, the subwoofer is working just fine. Tried it on the Denon by my neighbours and the volume output is ok. So the sub is not broken.

The factory reset of the MRX didn't work

At last I tried ARC again, but the results are about the same.

So I still have the same low volume output from the MRX500 to the subwoofer.

Can't try another subwoofer in the next weeks, so I don't know what to do now. It seems there is something wrong with the Anthem.

Extra problem is that the Anthem is out of warranty

Where is the sub placed in the room? Have you tried moving the sub to a different place in the room? Could it be that the sub is sitting in a null where the bass frequencies are cancelling each other out?

I'm no Anthem expert. I just picked up a 300 myself. I haven't even run ARC yet. I'm sure I'll have some questions in the near future though.

The sub has always be standing there, on the left of the right front speaker, and has never given problems there. So no, I haven't moved the sub.

Hello, I'm a bit baffled by your issues. When you tested your sub
At your neighbors house did you have turn the gain/volume
Up to get good volume?? Just curious how far up you turned
The volume.

I can't really think of any other possible solution.

My previous AVR had Audyssey XT32. Before measuring I used a SPL meter to set the subwoofer at a level op 75dB. After that I did a 8 point measurement and everything was fine.
Volume in the settings of the sub was then -25 on a scale of -80 - 0dB (electronic soundlevel system)
The same this afternoon with my neigbour. Sub on -25 and it sounds great.

When I use this setting using ARC measuring stops with an error because the sublevel is too low.
After raising the volume on the sub to -10dB I get the results of the posted scale, with a peak of 70dB.
So it looks like the sub-out is not "hot" enough.

Could very well be...try bumping the sub trim level
Higher in the MRX.

If you used -25 on your your sub setting then
To me that is turning it up pretty high.

I have another idea...if you have a "Y" rca cable could
Try to hook it up to the left/right inputs of the sub.
The single end would of course go into the MRX.

This kind of cable
http://www.amazon.com/Mediabridge-UL...5141447&sr=1-1

I've heard you can get more output doing this.
You need to change the input on your sub though

Quick question before I have to go to bed (It's midnight here in the Netherlands)
Such a "Y Cable" has to be put in the L-R connectors. Those are analog connectors and not LFE right?
Does these connectors work with digital audio including LFE?
Thanks again, you are extremely helpful.

Yes it will work just fine, remember you will
Be using the LFE out put on the MRX.

Also need to tell your sub that you are not using
LFE input rather left/right input. (From your owners manual)

Hi, sorry about the delay, but I had to wait till the spliting cable had arrived.
Well it didn't help. Output with this cable was around 35dB, so hardly audible.
I also tried different 8 places in my room, that helped a bit.
This is the best I can do. Subwoofer output still at 90% at LFE position:

Added the first measurement of the subwoofer

Sorry it didn't work out. I'm fresh out of ideas.

Your sub graph on post #16645 is a better looking graph.
But, on this new graph you picked up about 5db's of
Output. I prefer the older graph. It doesn't have the
Peaks and valleys that ARC had trouble correcting.

At this point the only thing you can do is raise the
Sub trim levels in the speaker level menu. It can go
As high as +12...

I still wonder how a different sub would do? But,
Based on on your current sub being tested at your
Neighbors place, I am not sure if it would make a
Difference.

No 4K on the MRX 00, the newer ones will pass it. How are you running 4k? There's nothing out there for it outside of streaming?

3D pass through

Hi All,

I have a GT640 GPU in a HTPC running JRiver -> HDMI to MRX 500 -> 3D capable projector

Is this possible?

Thanks

Roh

EDIT just found out JRiver doesn't support 3D

Absolutely! Run QM first to establish best sub location (fewest large dips, ignore peaks). Experiment a lot until you are sure. Then run ARC, it will be superb. For even better, find Dmsoke's (sp.) method of correctly setting phase (likely in D/AVM section). If the sub is even competent it will be a true revelation. Especially listen with well recorded music.
