Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 539

post #16141 of 16451
Hi Folks. I am new here. I have an MRX 700, that just today gave me a problem. I moved my setup due to a new plasma TV. Had the fronts, center, and subs connected since moving it (all monitor audio)wink.gif. Today I hooked up the surrounds, and ran the ARC. It went through the test tones for the front L, centre, front R, surround R, and then nothing from surround L. Checked speaker and cable, all seemed ok. Tried again with same results. Switched left and right speaker wires at the receiver and the left worked in the right channel, but the right did not work when plugged into the left channel, speakers switched also and they work, which leads me to the receiver. Is it possible that the rear channel amp is blown? Any suggestions?

UPDATE - after measuring and testing the cables and speakers, which all tested 8 ohms at the speaker cables when connected, It worked and them didn't work a few times. Seems the problem is in the terminal on the back of the receiver. Its all working now, so I will leave it alone for the time being.

Hi, I just got a new MRX 300 and finished the ARC run. I am posting the pics of ARC to see how it looks. I ran the automated and not manual but I think it did a good job. Only a few questions. It set my speakers to small 60. I have the Ascend Acoustics CBM-170 SE in a 5.1 setup with an HSU VTF-3 MK2 I have usually set the speakers to small 80. Should I trust ARC and just leave them alone. it sounds good to me so I do not really want to mess around much with it and mess it

WOW! Your graphs look great! Your sub graph is very nice,and
Considering that proper sub interaction is what drives most of us
ARC users nuts, you did very well!! I would not worry about ARC
Setting your mains to 60 hz....just means you had solid,measurable
Response that low!

I wouldn't mess with success...enjoy!
post #16144 of 16451
Thanks. it sounds great. But it set up all 5 speakers to small 60 and thats why I thought it was weird. I just had time to watch one movie after setting the ARC (I ran it a couple of times and it set the 5 speakers to small 60 each time). I watched WAR and man the scene where he blows the office was brutal biggrin.gif I am leaving them alone. They can technically go to 58 I believe so 60 should be fine.
post #16145 of 16451
i have a question. Is there a way of turning up there bass on the main 2 speakers without it affecting the subwoofer? As i turn it up i hear the sub get louder. So whats the difference between turning the bass up and turning the subwoofer level up?
post #16146 of 16451
What are your front left and right speakers? If your main speakers are small bookshelves, it makes sense that boosting the bass using the mrx's bass option would increase the bass from the subwoofer and not the mains.

Turning up the volume on the subwoofer would cause the frequency curve to vary from what ARC had calculated. If you want more bass, I suggest using the bass control on the receiver rather than boosting the sub's volume control.

when i turn the sub up, i turn the sub level on the receiver up. not on the back of the sub. I am running bookshelf's but want more punch from them. thats why i was trying to just put the bass up on them separately.

You're turning up the sub level or the bass level on your mrx? I believe they are two separate settings. Turning up the sub level will affect only the sub.

i am doing both. I turn the sub level up for the subwoofer only on the mrx. I then turn the bass up, but i only want the bass on the main L and R speakers to go up, not the subwoofer also when i adjust the bass.

The mrx is not capable of increasing the amount of bass coming from only the front speakers. You want this for movies and music?

you could try manually adding room gain in arc
post #16152 of 16451
no, i don't want to do that, all i want to be able to do is turn the bass up only on the main speakers. Only way it works is if i turn the subwoofer off. This is how i listen to music and is fine, but when i want to run the sub also it turns bass up on the subwoofer.
post #16153 of 16451
You could rerun ARC and uncheck the sub on your music profile and run your speakers full range.

I don't think room gain is gonna boost the sub, it boost all the other speaker.

With the way bass management works (on pretty much all receivers not just Anthem) if you are running your speakers as small any bass below the crossover goes to the sub. So if you increase the sub you will also be increasing the bass below each speakers crossover because the bass below the crossover of each speakers get mixed into the sub. If you want to increase the bass in your mains and not have it go to the sub your mains need to be set to large and the sub set to off.

If you wish to try it with your music or movie config just go into Speaker Configuration >> Bass Management from the MRX main menu. You can change the fronts to large and sub to off on the fly and switch back whenever you like.

If you don't set the sub to off in the menu the sub will be increased even if your mains are set to large and you'll get double bass because speakers set as large and the sub will be playing the same bass.
post #16156 of 16451
Keep in mind..
That if all the loudspeakers are set to Large, the only signal to the subwoofer is the LFE (.1) track..
However it depends upon the source input, is it 5.1 or 7.1?
If there is no LFE track in the source medium, then the bass manager must CREATE the subwoofer out by low-passing a summed front L+R signal...
And if the front loudspeakers are large, this requires the subwoofer to be set to L/R + LFE. Note some brands call it something similar.
An example of such as source medium without an LFE track would be FM stereo, or any stereo 2.0 source.
Also any loudspeakers set to SMALL will redirect the low frequencies of that loudspeaker to subwoofer out, so in a traditional 5.1 or 7.1 system where ALL loudspeakers are SMALL the subwoofer out signal is the redirected bass frequencies plus the LFE track....
One nice touch some AVRs have is a separate LFE trim level control in addition to the subwoofer trim level control, so the LFE level can be set to its own level then mixed with the redirected bass frequencies for any loudspeakers set to to SMALL.

Just my $0.05.... 👍😉

rerunning ARC with sub off in music is a good idea, but i do use the sub for music at times. Also when i was watching a movie i wanted to put the bass to +2 on the mains. I guess i can't really win with this one.
post #16158 of 16451
You don't have to rerun ARC with the sub off. Just go into the Speaker Configuration >> Bass Management from the main menu and you can turn the sub off and change the speakers to large all without rerunning ARC.

What speakers do you have? Did you save the ARC graphs?
post #16160 of 16451
i have paradigm mini monitor v7's, svs pb12-nsd subwoofer, and the graphs are on my other laptop, ill pull them off it today and post them up.

Maybe there is a frequency dip were the fronts cross over to the sub and this is making you want more bass from the fronts? I'm just guessing here.
post #16162 of 16451
i was looking and i can run full range with sub on music. i might try that, then if i want to turn the sub off i can. Just not sure how these speakers will preform loud on full range. Normally when i turn the bass up on them only (sub off) i don't crank them.

here is my latest arc run…

mains are at 60, sub at 80. room gain at 3.9, subs set to flat on movie but not for music (forgot to check the box i guess, so i will have to re-upload later today)

front Left - 0
front Right - 0
Sub - -7

post #16163 of 16451
First off, I would reduce the sub volume and re-run ARC. Your sub's volume is being reduced by 7 according to your post.

post #16164 of 16451
yea, i know it needs to be turned down a couple notches. Im hoping to go back to dual subs again in the future as i made the mistake by selling 1 as i live in an apartment, but the bass from 2 subs was so much smoother around all the seating, that its hard to get used to it now. any other suggestions as from what you can see from the graphs? i spent a few hours a few nights ago moving the sub around a few different places and for some reason, in the corner but out from the back wall roughly 2 feet was the flattest i could find on the quick measure. I also ended up pulling the main bookshelfs back closer to the rear wall.

Given the sub you have, set ARC to flat under advanced settings. Also, your sub looks like it is rolling off a bit too quickly above 50 hz which may be causing the need for more bass in your system.

Did you disable the sub's crossover?
post #16166 of 16451
yes subs filter is set to disable. Also i didn't notice i only set sub to flat for movie. ill have to change it on the music. What i can do is, i can move the sub around, take a bunch of quick measure shots and post them to see, but i thought it rolled off early also! i need to get corner bass traps soon!

Is the room open or closed? Size? If it were me, I would try moving the sub and fronts around to get a better blend as you suggested.
post #16168 of 16451
the room is rectangle, 1 end is open to hallway/small room where you enter the apartment, on the back corner there is a door way into the kitchen. room size is : 15.5 ft x 12.5 ft x 7ft tall. what should i be aiming for when doing quick measure and moving things around. My understanding is making everything flat as possible across the graph? also, thanks for taking the time to help!!

No need to thank me as we're all here to help.

Since the room is open on one end, that may be part of the problem in that one sub may not be enough to pressurize the room.

With quick measure, you're trying for a sub position that will reduce the roll-off. I have my sub right in a corner and it does quite well.
post #16170 of 16451
ok ill try over the next few days to re do some quick measures and see if i can get it to roll over not so early. If i wasn't in the middle of a motorcycle build i would run out and grab a 2nd nsd and some corner traps!
