*Official Thread* Anthem AVM 70 & 90 and MRX 540, 740 & 1140

@Gondon72, your mains are drowning your centre speaker. I have made some changes to your .arc3 file. Hopefully it will make your system sound a little more integrated.

Dialogue sound better as compared to previous now (but still softer compared to previous firmware). However, i do not have any more space to shift the speakers further away as it is in my room as shown below.

Did you redo your ARC after you have updated the firmware? If not, pls do another round of ARC as the latest firmware addresses a few issues related to the weak bass which in turn may have an impact to the overall sound.

Lastly, what is your normal listening level? Between -30dB and -20dB is very typical for Anthem user. Anything out of this range is more of a preference - e.g. you wanted a more cinematic feel or just don’t want to disturb other people. If you place dialogue as more important over surrounds and bass, then you can just enable “Dolby Processing” which is Anthem’s version of dynamic volume akin to Denon’s implementation but not as aggressive.

Yes, i redo the ARC after the firmware update. My typical listening level is between -38dB and -32dB only as is already quiet loud for me. Even for 2 channel music is around 42dB and 36bB.

Ok, i can try “Dolby Processing”.

Sometimes it is the power amp that you paired is the cause the huge jump in trim values. Best is to pair with Anthem own power amp for compatibility.

Hi there, can anyone help. How do I run my left, right and centre speakers full range and still use my subwoofer to only play 80hz and below.

For those who are easily distracted by the “bright blue ring” on the power button of your Anthem MRX/AVM. You can buy these reinforcement rings used on papers and folders to “reduce” the “brightness” level. The punch hole is perfectly-sized for the power button. :slight_smile:

I bought it at Daiso.

Hi all,
I recently joined this group.
I have had browsed through this forum in past but not an active member. Thanks for sharing your thoughts for the anthem owners here.

I have recently purchased an avm 90 and happens to have an avm 70 4k as well.

Apologies for a long first post.

While performing QM with arc for the avm 90 my test tones register 5-6db less volume with arc toggled off and compared to the avm 90.

I am using arc 1.7.4 windows and both processors are at 2.3.213.
Avm 70 was updated with beta 2.3.213 and looks like later it became official release

All I do is switch the xlr cables from 1 processor to another keeping everything else same including mic position untouched.

My speakers and my subs both register a 5-6db lower value compared to the 70.

This reflects post full arc calibration run as each of my channel trims are 4-6db higher with 90 compared to avm 70 results.Few of my speakers are now having +8db trims where they used to be +3.5db.

I have had some suggestions from the avsforum and Facebook group members and they do make sense with that design for each processor being different and a change is expected. I will share my arc files asap.

However, I am surprised that not any other user have ever reported this and I am concerned if this is isolated to my 90 unit alone.

While browsing this forum I came across few similar observations in the past with arc 1.6.5 versions where a member @Ronildoq had exactly similar experience to mine .

Whatever he had posted then for the 90 is experienced by me now . In fact his QM measurements posted here with arc toggled off reflected 68 db for his fronts same as mine resulting in increased trims post arc calibration run to achieve level 75db.

These same fronts of mine are +75 to +76 db with avm 70 QM measured arc toggled off.

As a result of this lower test tones and resulting arc calibration, it has also shifted my listening volume with avm 90 by -8 to -10 db lower.
If I used to hear at -22 to -25 multichannel, now I hear those same tracks -30 to -35 db.
Used to listen atmos tracks at -14 to -18 db in Apple Music and now I hear them at -22 to -25 db.

Has anyone here experienced higher trims with the avm 90 compared to avm 70 just incase upgraded.

I don’t see any problem in your case. As a rule of thumb, as long as the trim values are well within the ARC correction, you should be fine. The only thing is the adjustment of the master volume.

Is it normal that the room gain in a small room is greater than in a large room?
ARC has determined a room gain of 5.75 dB in my room.

My room has a size of approx. 12 square meters.

It really depends on the speaker placement and where is the location of your main listening position -i.e. your seat.

If you want, you can send me your .arc3 file and have a look.

How can I send a PM here?

I have emailed you the edited arc3 solution. Pls check and let me know how it goes.

BTW if you can, pls explain why the intentional “dip” at 3KHz for your mains using the DSP. Thanks.

I have sent them an e-mail about this, with attachments.

I am new to the forum with a recent purchase of an AVM 90.
My question is this: My fronts have internal processors (Paradigm 9h) with ARC already in place and my subs (Perlisten D215s) have internal correction (PEQ, TXH, etc).
When running ARC from my preamp over top of all that - my concern is ‘too much processing’. Any ideas?
Anthem said just keep the internal correction and run ARC from the preamp on top of that…
PS All of my current corrections are with a large Christmas tree in the room - so I’ll have to run everything again in January! Still having fun though…

If I were you, I’ll just go with ARC from the preamp (AVM90). I do not have experience with Paradigm speakers or subs but they should be using the same ARC solution as the AVM90. Having said that, you did approach Anthem for advice and was told to keep the ARC solution for your mains and continue to ARC on your AVM90, I guess they know something we don’t. But even so, I see no issue running full ARC on all your speakers and the subs (bypass the PEQ and THX mode if you can) using the AVM90.

My 2 cents.

Thanks. So much helpful info on this forum. I’ve spent weeks studying it around ARC and the AVM 90.
I’ll wait to see if anyone else chimes in…

Can you tell me if this is a 4k or 8k HDMI board for an Anthem AVM 740?
I’m hoping it’s an 8k.

This started with a known good 4k board. It was replaced with what I thought was an 8k board but it was not, just a known good 4k board. I returned the supposed 8k board and reinstalled the original 4k HDMI board and now I get this message: OSD Update “No Flash” and the unit locks up. Is there any ability to reset or recover without sending the unit back to Canada?
