Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 270

Way to stick with it! But you learned how to use Quick Measure and how useful it can be... pretty cool tool on the whole!

I think Jayray and Bob both have you covered with instruction on how to set "Flat", if you think you are missing something, let us know and we can revise/expand on the directions for "Flat" setup a bit more.

Be sure to post up ALL of your graphs, Targets window and Speaker Calibration Numbers after you get done! For the graphs, make sure you take your screen shots AFTER you hit "Calculate" so that you have both the red and green lines.

I'm assuming your new level of 9 is below what you had before (if memory serves me, I think it was 10?). Hopefully all of your levels will land between -3 and +3 when you are done!

Congrats, I can't wait to see what it all looks like!

**** Oh, and of course, you need to re-run ARC for all of your speakers including the sub now that you have the sub in a new location (assuming you haven't already done that). I would make sure you put your A/V screen back up and in place before doing this final ARC run as it may have an influance on the higher frequencies that ARC sees and corrects. After you have re-run ARC, that is when you will set the targets window to use "Flat" and then re-calculate and upload. And of course make sure you save your final ARC calibration file... give a great name like "Final ARC Run with Sub in Back of room ****

Ha! Yea, each of my two custom subs weight in at about 125lbs as I recall!

I was thinking the other day that they couldn'y weight that much... but then I weighted my custom front speakers after I finished building them and they came in at close to 50lbs each... and they are about 1/3 to 1/2 the size of the subs and the subs are double walled 3/4" MDF... where my fronts are single walled 3/4" MDF with corner strips...

Atabea,

One last thought... if your read Bob's post a few posts up on multiple subs, there were a few tips that would make sense for you as well once you are finished...

With your sub now behind you, depending on which way it is facing, you may want to switch the polarity of the speaker. Also, you probably want to listen to some FM radio static... as Bob noted, listen carefully to the low end sound it is making and adjust the phase control on your sub till the low frequencies sound loudest. As Bob said, sneak up on it from both sides and then use the middle of the range you find sounds best!

Happy hunting!

Thanks Tigger, Bob, Jayray and shrike645, I am about to follow the above instructions and report back. Fingers crossed.

Don't forget to turn your sub down. I'm sure you'll like the end results.

At what point should I turn the sub doen, before uploading or after uploading? Also, when I ran Arc, the measurements were taken with the sub in its normal position (9 oclock). Do I still have to turn the sub down?

thanks
atabea

Turn it down before you measure again. ARC calculates the calibration during it's measure. I think you posted the calibration levels twice and both times it was too loud.

My speaker settings are now:

Front right +2db
Center +2db
Front Right +1db
surround right -1db
surround left -2
sub -3

My charts are also attached. Everything looks to be within normal parameters. Hopefully this is it!!

Can't see the fronts but it all looks good.

When I did my last measurements I left it at 9oclock and I got the results in the charts. Not sure, but it might have something to do with the final location of the sub that did not require me to turn it down to get the outcome. However, do you think I should turn it down and run Arc again.

thanks

atabea

here are the fronts.

They look very good now. Upload and listen. It should sound great
John

If it's still in the -9 to -10 range it should be turned down but I guess I would only do that if you were going to measure again. I don't think I'd make another run just to do that.

Hi, this is my first ARC.
Any tips?

Not too bad. Your fronts need a little work. It looks Like they are a bit close to the walls. Especially the left. The dip they both have near 200hz isn't fully corrected in the right. If you can move them a bit and get the chart on the low end down a bit and get rid of that dip I think you'll find that ARC will move the crossover lower.

Your sub looks like it could go to flat in the advanced mode. We've talked of the settings for that a few posts up.

Thanks, you're right, the front left is near a corner, difficult to move from that.
I will read your posts.
The subwoofer is not in flat. The peak betwen 20 - 30 htz, must/can be corrected?
One more thing: to my ears it seems a little flat sound.

Based on the measured charts it looks like you might have got used to more bottom end than a corrected curve. The fronts aren't too bad but moving them even a few inches might get rid of that dip and help ARC to lower the crossover which would help you with the flat sound.

Do you have room to move the sub? I would guess again that the rise between 20-30 hz in boundary gain from being in a corner.

Quick measure for both the fronts and the sub would really help you even if you are only able to move them a few inches.

When you have the best you can do with ARC give it a listen for a week or so to get used to a corrected room. There are some options like boosting room gain if you feel it still sounds flat. ARC has set your room gain at it's max but it can be changed manually, recalculated and uploaded.

Atabea,

Things look really good now! Levels are exactly where we would like to see them between -3 to +3.

Speakers look good as well given the space you have to work with. ARC is managing them well and correcting for most anything we can't fix with location limitations.

I would sit back and enjoy!

The one thing you may still want to do, is to adjust the phase of the sub. You would do this by sitting in your primary listening position, listening to radio static between stations... then have someone turn the phase knob from clockwise to counter clockwise all the way and then back... have then note where on the dial you are telling them it sounds "loudest". Note you only want to concentrate on the low end of the static.

As they go from one extreem to the other, the person turning the knob will probably find there is a range you like. If that is the case, just pick the center of the range!

Your latest Calibration levels look great, no need to change anything (assuming that the level of the sub is set where you had it when you ran ARC).

+1 Shrike645 is steering you in a good direction I think.

If you can, try to get your fronts further away from the corners they are in... try about 2' from any walls if possible.

And as to flat, again, I have to agree, I think you may be used to some really inflated bass... give your current settings a try for a week or two of solid listening and I think you will find that you are hearing much better detail in the low end and you will find it is not that flat, after all, once you get a bit more used to it

What did ARC set your Speaker Calibration Levels to? I'm betting your sub has a negative number... I have a feeling that it has probably been running to loud as well...

Please post up your Speaker Calibration Levels.

Again you are right, the sub is in a corner (difficult to move but will try).
which leaves me puzzled is the fact that moving the front speakers randomly up to 25" (could not leave them there) doesn't make big changes. The 200htz dip is almost the same, maybe a speaker issue/attribute?.

Thanks for your patience Shrike645, mine starts to fade because the reason to buy the Anthem was just try to improve the acoustic.

Something with the fronts is making ARC set the crossover/cutoff at 100 and it looks like they measure better and should go lower like 60 or 80. I'd rather see that changed by moving but it could be forced in the target window, recalculate and upload. I never like to recommend overriding ARC for this. It's the very very very last thing I would try. I don't mind changing the room gain value if a user feels it needs it.

Hi Tigger!,

I hope you are right and with time I listen better sound.

I'm uploading (I was playing with quick measure), then I will post the levels.
Any other thing to post you?

Here we go:

Dolby Volume Leveler: OFF
Dolby offset: 0
L +2
c +3
R -3
SL +3
SR +3
SB -9 !!!!

Yup sub is way too loud. Happens a lot around here.

Yes, I can see, but if the A/V has headroom up to -12, what is the problem?.
excuse my ignorance, I am new to these topics and try to understand everything you say me.

You are pushing 12db (sub -9 and surrounds, center +3 = 12 db). It is my opinion that the trim or boost to speaker calibration does not use any resources but there has been some discussion on that and I haven't seen any definitive agreement. That aside I'm a little detail oriented and if I were do a measurement again I would turn down the sub to get the calibration levels +-3db.

How is it sounding?

OK.
I'm going to measure now. Before starting another doubts:

-is interesanting mark the "same as movie" option? (I use it more for music than movies)

-any recomended change in the target tab?

Thanks one more time.

You can measure with the "same as movie" checked and then if you want you can remove speakers in the music option such as the center and surrounds and recalculate. You can assign the music or movie mode to each source or source overlay.

I wouldn't want to change anything in the target until we see the set of charts you are measuring now. If we do need to change the targets you don't have to remeasure, just change the value, recalculate and upload.
