It works and works well. I've done that in the last week or so, and can use an optical connection. If you've got any old spare AppleTVs (pretty much any of the black ones) they can also be used, some optical as well as HDMI.

This may be a stupid question but does the MRX-720 support HDMI 2.1?

No. No AVRs currently support HDMI 2.1. Likely won't see HDMI 2.1 48Gbps chipsets until 2019 models at the earliest.

Hi everyone. I recently finished building my GradSubs and installed them in the theatre room - first subs this room has had.


After running ARC I was confused to see that it decided to cross the front left and rights at 250Hz. The centre was crossed at 100Hz.




I'll try the play with the angles of the fronts, but theres not much to play with as you can see. Any ideas on whats going on? The mains have 15" drivers and should be able to play lower.

It's not they they don't play deep, but the dip below 200 Hz is what's ARC is seeing. I suspect a side wall SBIR issue. Nothing works as well as distance in shifting it down to a lower frequency and lower degree of effect. Might try some very thick absorbers at the side wall first reflection point (can try on one speaker with quick measure just to see if there's any change in response.) Not easy to absorb <200 Hz, though.

Thanks Roger. I do have some absorption sheets waiting for me to make panels out of. I might lean 12" worth at the FRZ and do a quick measure, as you suggested.

Got to say it is cool seeing all the curves and how much different the uncorrected ones are.

I've only done my initial run through (I still have another sub to connect, plus I've waiting on my recliner, so until the deadening nature of that is there I'm not wanting to spend too much time) and I have Kef Q series all around (except the SVS subwoofers), and the uncorrected responses were all so smooth and close.

Although perhaps not germane to the question at hand, I note that the center trace clearly shows the affect of the ARC room gain value, but the LF channel does not. Perhaps because if the high crossover?

Just a quick question. When listening to pure two channel stereo on the Anthem MRX 720 you should disable ARC right?

On the advice from another member I have made a 2.0 and a 2.1 profile and what’s your opinion on ARC/No ARC on these two profiles?

Thx in advance.

Not in my book, but feel free to use whatever you like. You can toggle it on and off, so to do your own listeng tests.

I would never disable ARC because in my room it sounds incredible, but you should try it both ways and see if you like it on or off. If you want "pure" 2 channel where you're using the DACS in the source player with an analog connection you need to set "Process analog Audio Input" to no in the input menu.

I would never enable ARC because in my room it sounds crap Each to their own it really is personal preference and largely depends on the environment. For stereo listening I would disable it in any case unless there are huge dips in the frequency range.

Thx for the advice! I have created 2.0 (ARC), 2.0 (NO ARC), 2.1 (ARC) and 2.1 (NO ARC) profiles and will be testing later today. Do you have your sub/subs enabled when streaming music from services like Spotify, Tidal etc.?

Hello again! As I recall it you have commented on other users ARC results before and maybe you would like to comment on mine?

A user in another forum advised me to bump my center to 90hz and my surrounds to 110hz "to get it away from the side wall" (the left front) and I'll have to experiment more on that (as you can see my fronts, surrounds and sub are all set to 80hz).

I'll admit that I am a bit of a noob in the ARC world so any tips are more than welcomed.

I hate ARC. It took all the magic out of my speakers and made them sound like any old $300 speaker. Couldn't turn that crap off fast enough.

I like it in my room. I particularly like to have dolby volume on when listening to low volume level music. It acts as a 21st century loudness button correcting for diminished volume perception in bass and treble as volume is reduced. If you use it make sure that dolby volume leveler is off (at 0).

Hi I'd be happy to help. The first thing I'd do is in the ARC target window change the "Max EQ Frequency" from 5000 to 20000. All of your speakers (except the center) are dropping off at 5K when your speakers are capable of doing more. Change that setting to 20000 and all your speakers will follow the target curve.

I've noticed you made some changes to the sub setting in ARC. What sub are you using? And have you disabled the sub's crossover by either turning the crossover knob on the back of the sub as high as it will go or a switch that turns the crossover off?

As for bumping the center and surrounds crossover I don't see any reason at all to do that. ARC set them where ARC determined was the lowest they are capable of playing so no need to change the crossovers. The left front has a dip due to placement/room but if your speakers are in a place that is athletically pleasing and you don't want to mess up our room I would leave it there. Now if you have the flexibility to move it try just a few inches at a time.

Thanks

Hi Legairre! Thx for the reply!

I have changed the "Max EQ Frequency" to 20000 and calculated again (and attached the results). I haven’t uploaded yet as I am not at home (will upload this evening).

My sub is this one – https://audiovector.com/sr-sub-super.html – and I have attached a screenshot of its specifications. And yes, I have turned the crossover knob on the back of the sub as high as it will go as a user in another forum recommended doing this.

My fronts are by the way theses: https://audiovector.com/sr-3-signature.html, my center this: https://audiovector.com/sr-c-signature.html and my surrounds these: https://audiovector.com/qr-wall.html

I have also attached a screenshot of my “Profile 1” settings (where I have set my fronts to 80hz as I was recommended this) if this can be of any help.

Would you change any other settings?

Thx again!

Hi, what was the crossovers before you changed it and why did some one recommend changing it?

The fronts were set to 250hz originally, and a user advised me to set them to 80hz and redo the room correction (as you can see below):

"They should be set at around 80hz (give or take) assuming they are set to "small".

It looks to me like you have floorstander tower speakers for your fronts due to the frequency response at the 30hz and above but you're killing them with the 250hz crossover.

Are they close to a wall? Looks like they could be....

You need to set your front crossover to 80hz and re-do your room correction."

I your advise is another number could I just put in a new number in the ARC software and redo the calculation - or should I set the microphone up agagin and do new measurements?

Thx for help!

I agree your fronts are are rated down to 27Hz so leaving them at 250 would be terrible. I've never seen ARC set fronts that high even close to a wall. How close are they to the front and back walls?

They are about 13,2 inches from the side wall and 8,5 inches from the back wall... "Aesthetically" I think the setup is fine... Is something bad going on?

After looking at the graph further it makes sense that he told you to set the crossover to 80Hz and it makes sense that ARC set them to 250Hz. The left front has a big dip in the 175Hz range that ARC could not bring up high enough to correct. The front right has a dip in the 200Hz range, but it's not nearly as bad as the left front and ARC was able to correct it. Because ARC couldn't fix the left front it set the fronts to where the dip was, so due to that dip ARC thinks your fronts can't play lower than 250Hz. The advice you received to set your crossover to 80Hz was actually good advice.

If it wasn't for that dip ARC could have set your fronts at 40Hz (just for fun try changing the front crossover to 40 Hz and you'll see other than that dip on the front left at about 175Hz the fronts play to 40Hz).

There's not much you can do about it without messing up the speaker placement, but then that would throw off the aesthetics of your room. I'd try moving the fronts about 12 inches from the back wall but leave them where they are from the side walls just to see if that makes a difference.

THX again!

"Aesthetically" I will have to talk with my girlfriend about putting the fronts 12 inches from the back wall...

Your advise on setting the “Max EQ frequency” to 20.000 – I should leave the number on 20.000, right?

My English is not the best but do you suggest – just for fun – that I should try to change the front crossover to 40 Hz? I have tried doing so and I have attached the results (but haven’t uploaded anything).

But – other than that – I guess there isn’t any other settings I could try in order to optimize the sound (other than trying to test with alternative placement of the front speakers)?
The system sounds great now, so thx so much for the great help!

So let me ask you this: At a very high level how does ARC sound on/off for multi-channel in your system? For my 2-channel setup turning ARC off was a no-brainer. However I still have ARC enabled for my Atmos 5.4.2 setup. Thinking of disabling it tonight and running some tests...

Projector/Screen: Sony VPL-VW285ES; Da-Lite Cosmopolitan Electrol (92")
TV: LG OLED 65B6P
Amplification: Anthem MRX-1120; Aesthetix Mimas; Rogue Triton II
Sources: Pioneer UPD-LX500; Simaudio 260DT; Music Hall mmf-9.3; Goldring Eroica LX
Speakers: Wilson Yvette (L/R); Paradigm In-Walls (6); Hsu Research VTF-1 MK3 (2)

Don't say anything. Move the speakers forward an inch or two then wait a few days. Move them forward a bit more and wait a few more days. Repeat as necessary. If the girlfriend notices, just say you're doing a little experimenting - make sure to point out if they seem to be sounding much better that way but acknowledge that it doesn't have to be a permanent change if it really bothers her.
