Arry74 Posted April 10, 2024 Posted April 10, 2024 Hi I have an issue after having had my MRX 720 repaired with a new board. The initial problem is fixed however i can no longer get sound if I use EArc from the TV to ARC on the Anthem. Video works fine. The only way I can get audio is to set-up a new Input and set Audio to Optical In and use an optical cable. Is very strange, have tried different HDMI output on the Anthem, have tried setting audio to HDMI and not ARC but still the same problem. Has anyone come across this before? Cheers
betty boop Posted April 10, 2024 Posted April 10, 2024 Isn’t this exactly same ? Obviously these anthems are not great with hdmi and video board ? https://www.stereonet.com/forums/topic/231088-anthem-av-owners-thread/?do=findComment&comment=6345227 “Word of warning. So I had a MRX720 with a faulty HDMI board (audio worked fine when using an external video splitter) and dropped it into AV Digitech for repair, they quoted my $1000 to replace the HDMI board and after 4 weeks told me the video worked but audio did not they ummed and ah-ed and said another part was on the way to fix it, so they ordered a second part and then finally told me it was working but wanted another $700 to let me pick it up.” appears pretty much same issue ?
Arry74 Posted April 11, 2024 Author Posted April 11, 2024 hmmm i actually read that myself and was wondering the same. My board was fixed however, the issue at the time was the volume randomly going up to maximum without any input from the remote, would make you jump out of the chair. That issue is now fixed, but now this other issue. Was under warranty when my board was fixed but is no longer. I am not too familiar with the in's and out;s of hdmi v optical however by googling it looks like HDMI can play higher resolution audio so is a shame to miss out on it.

This happened to someone in recent months trying out a avm90 and been a few reports then from folks who experienced the same so consented to your machine 2 minutes ago, Arry74 said: but now this other issue.

Yes things like higher res picture and lossless audio need hdmi and would make it a must I would think even if out of warranty I would push on this under “statutory warranty” as possibly seems a common issue ? 1
Arry74 Posted April 11, 2024 Author Posted April 11, 2024 The technician that repaired it, said it is an issue because the Anthem gets too hot which affects the volume control but that's all he told me. hmmm yes I would definitely like to get HDMI audio working then. I will look into whether the issue can be sorted under statutory warranty. Thanks for the advice. 1
Arry74 Posted April 11, 2024 Author Posted April 11, 2024 Interestingly i just stumbled across my own post from 2019. I thought it was the TV but it must have been the amp. I have since bought a new TV but now I cannot remember how i had it setup. I presume it was just using an optical cable this entire time. I titled the post badly as ARC in Anthem world has another meaning. 1

Arry how is the anthem located ? inside a cabinet ? adequate ventilation ? peaking inside the box i have never understood this aspect of the anthem where they have a heatsink clearly which will have hot air rising ..but then it has a fan either blowing air on it but from just inside the box ? and flat upto the heatsink which will just push the hot air back into the case ? or if drawing away from heatsink its going to be pushing it on the hdmi board. quite a small heatsink as well so imagine it runs HOT ! so can understand the tech saying what does that anthem gets to hot and effects the volume control... especially if tis the board alongside the heatsink ! and hdmi board that is also along side it ... have you considered monitoring temps with either sitting a temp probe on the case or slightly poking above the heatsink ? might find elevated temps ? in which case it might be worth getting a usb fan eg the ac infinity ?...sit on top of case and let it draw air out the top
GaryT Posted April 12, 2024 Posted April 12, 2024 I can confirm these run extremely hot and should be totally located in open air (not in a cabinet) and with auxiliary cooling like an AC infinity AV cooler if possible. Hell, I think I might get some stick on heat sinks and attach them to any uncovered chip that shows up on my thermal camera. That said, I've never used the ARC audio on mine, since it doesn't support E-ARC I am running everything directly to the HDMI ins and don't use any TV app audio at all. Some things to check though, reset all CEC options (CEC is usually required for ARC to function) and reset the audio settings in the TV too. might be worth attempting a factory reset of the amp itself if you don't mind re-kerjiggering your settings. As much as I love the performance and features (virtual inputs is my favourite feature) I doubt my next receiver will be another Anthem. 1

It is in a cabinet however the front and back of the cabinet are open. The bottom obviously is touching the cabinet however the top of the Anthem is very close to the cabinet top so yes I can see how the top of it could be getting pretty hot. The thing is though that HDMI Audio has never worked even from the very beginning so i dont think that heat could of caused this. 21 hours ago, betty boop said: have you considered monitoring temps with either sitting a temp probe on the case or slightly poking above the heatsink ? might find elevated temps ?

So you just run the TV and any app like Netflix via the TV speakers? My TV has an E-ARC port which is also ARC from the looks of it so i am thinking that that should work? Yes I have reset all CEC options on both the TV and the Anthem. When I received the Anthem back from repair it had already been reset.
Arry74 Posted April 12, 2024 Author Posted April 12, 2024 One thing as well I am unsure of is how the Inputs work exactly. For example for the TV the HDMI cable goes from the TV Input to the Anthem Output, this makes sense to me. Then the 7 inputs on the Anthem are used for things such as my DVD player. This also makes sense as I have a HDMI cable going from the DVD Player Out to the Anthem IN and this works correctly, i get picture plus sound. The only way I can get audio from the TV to the Anthem is by configuring the Input as per attached picture and using the Optical Cable. What I don't understand is why the sound only works when I select the optical option on the audio, i.e. this is an Input so how does it relate to the TV? Why does the TV need to be configured as an Input to work? Hope you understand what I am saying. Cheers

If HDMI arc audio is not working on your unit then yes you would have to configure an input and use optical, call it TV, then switch to that input when you want to use apps on your TV. One of the audio sources when configuring an input is called HDMI ARC, that is the return audio from the TV that run back down the video output cable. Even in that configuration, the TV is an input, its audio feed is a separate source that needs to be called up when you want to use it rather than for example direct audio from a device connected to the receiver, like a HDMI Bluray player or streaming box. Same when using an optical cable, the TV is outputting audio and that is just another generic source as far as the amplifier is concerned.
The Bluesman Posted February 5 Posted February 5 Hi all, I've just discovered this thread as I'm now having issues with my Anthem MRX720 and TV audio via the HDMI input, it was working great for so many years, I Dom.t know what to do about it and I'm over trying to work out the problem. Do you guys think the 720 is worth fixing or just use optical, might be time to move on from my much loved MRX 720 maybe. My Amps volume was turning itself up to full volume and turning itself on, sounds like a few of you guys have had the same issues
GaryT Posted February 5 Posted February 5 I wouldn’t even try to get it fixed. it will cost you double what they quote and will break a week after being "repaired" then they quote you another $1000 to fix it. Worst repair experience I’ve ever had in my life. Cut your losses and walk away from it.

It's a shame as it's worked faultlessly ever since new, been reasonably happy with it and it's still works okay it's just the television ARC that doesn't seem to work anymore, as far as music goes I have been using it in AV Bypass mode with a Yamaha A-S2200. Has anyone got any recommendations for a replacement for it as I love the AV system for movies, TV etc

I probably don't need to spend to much as I'm more of a 2 channel kind of guy. in my theatre room I love having the Yamaha A-S2200 in AV bypass when I listen to music in that room, as good as the Anthem is the Yamaha was better for music, for me anyway

Nothing long in tooth about these … goes from 4A to 8A models - from cedia 2024 release so pretty current ! https://au.yamaha.com/en/products/audio_visual/av_receivers_amps/index_current.html 17 minutes ago, The Bluesman said: checked out a Marantz Cinema 60 that was going for a reasonable price, seems like a well built AVR and I like the silver one, will match my silver Yamaha A-S2200 By all means and yes marantz make good gear … but I wouldn’t discount Yamaha if like their sound will be a good sonic match with your a-s2200 Edited February 5 by betty boop

You can spend a few hundred dollars used to many thousands new, so please give a budget. And you need to provide more details of what is important, how many speakers sub etc. Otherwise pick something in Classifieds? https://www.stereonet.com/forums/classifieds/category/29-av-receivers-processors/

Guest Posted February 5 Posted February 5 Given the lack of budget, I am going to make some guesses. A new Yamaha RX 6VA may do the job at the $1K mark. A replacement MRX 740 is more than $5K, probably too much? Note that Yamaha will sound different to the MRX 720. A Marantz or NAD will sound closer. Denon is another option. Not sure how important room correction is but YPAO is very poor compared with ARC Genesis. Audyssey on Marantz, Denon is much better than YPAO but I prefer Dirac on a NAD. And with only 7.2 and no Atmos, suggest looking at a high end used AVR. There are bargains there because AVRs depreciate quickly, much more than stereo gear.

Thanks again Snoopy, it's been a while since I've been on these forums but if I remember correctly you had a MRX 720, not sure what you have these days but your knowledge on AV receivers is good, I can get Marantz Cinema 60 for a decent price, what are your thoughts on that Amp??
