Trevm Posted September 8, 2023 Posted September 8, 2023 Hello. I have an Anthem MRX540 - it was having some shutdown issues on big bass hits which was reported to Anthem, they blamed it on the ARC configuration at the time. I run all separates so it didnt make sense to me that the unit would be acting that way. The unit has now completely failed and will shut itself down after a short while and won't power up again until after a few minutes - nothing is connected to the unit. AV Australia advise it is best to deal directly with the manufacturer but at this stage their support has been woeful. Can anyone please advise on how I am best to proceed. Very much regretting my decision not to buy local and with a better quality brand.
Grant Slack Posted September 8, 2023 Posted September 8, 2023 Hi Trevor, I thought Australian consumer law made the retailer 100% accountable for consumer guarantees. https://www.accc.gov.au/consumers/buying-products-and-services/consumer-rights-and-guarantees So, if you bought it from AV Australia, they can’t say “it’s not our concern, talk to the manufacturer”. The law makes it their concern. OTOH if they are saying they have discussed your unit with the manufacturer, who has said they will handle it process-wise, that’s okay, but AV Australia are still legally in the picture, and the legal responsibility for your guarantees as a consumer remain with them and can’t be transferred to the manufacturer. But I’m no expert, it’s just my understanding. cheers Grant

Anthem used to have decent support. Have you tried calling them? And AV Australia has no idea, so I am OK with you talking directly, otherwise it would slow things down even further... 1 hour ago, Trevm said: .Can anyone please advise on how I am best to proceed. Very much regretting my decision not to buy local and with a better quality brand. I am confused. Did you buy the MRX 540 locally, new, from AV Australia? Nothing wrong with Anthem gear; you are just unlucky. I am somewhat surprised at Anthem's response because they usually have good customer service...

OzJustin Posted November 8, 2023 Posted November 8, 2023 (edited) Hi all Hoping for some feedback on a recent ARC Genesis calibration I've done on my system (see signature). I've run MSO and then conducted the usual ARC Genesis calibration but am getting some very funny frequency responses, crossovers, bass response etc. To summarise: - My main speakers (front left, front right, centre, surround left and surround right) all have a significant dip in response approx. 80-200Hz and ARC is choosing to roll them off very early. I recall this from previous measurements I took but never got to the bottom of this. Is it a speaker placement/room mode/SBIR issue I need to overcome? - The crossovers are being set all over the place (front left and right are 200Hz, centre is 80Hz, surrounds 190Hz, backs 80Hz, Atmos 80Hz, and subwoofers 250Hz)... - ARC seems to be setting my subwoofer target low and then boosting by +7dB (yielding a flat response around 85dB in REW). If I turn ARC off then with the same receiver volume I'm achieving 92dB. - When I measure the ARC corrected response in REW, I'm getting a reasonably flat response 8-80Hz then the bass response is rolling off, I assume based on the first 80Hz crossover. Given five of my seven bed layer speakers are being rolled off around 200Hz won't I have a massive gap 80-200Hz in bass response now? - The post MSO response is quite impressive 8-80Hz now. I haven't measured other seats yet but I'm impressed with this aspect of MSO so far. I've also noticed there seems to be better integration/time alignment between my SVS subs and the HoverEze now. Previously the HoverEze drivers would react late. Here is a copy of my ARC Genesis results if anyone would like to comment on the strange results. ARC Genesis Results 7.4.4 MRX1120 with MSO 8.11.23.pdf Here is a screenshot showing the MSO corrected bass response (with SVS subs + HoverEze) and ARC on (85dB traces) and off (92dB traces). The boosted 20Hz traces are with the bass traps fully closed. Here is a graph showing the response of each of my speakers from MLP with MSO and ARC both running. What do you make of these traces compared to the ARC corrected curves in my attached PDF ARC results? There are a lot of nulls 50-400Hz. Edited November 9, 2023 by OzJustin

I just wish they would add Roon fuctionality. We installed the AVM70 into a new theatre build at my son's place and I have to say I am more than impressed with this AVP. Firstly the sound is simply awesome and even better than I was expecting. It is also a delight to use , particularly with Anthem's excellent app. We have connected it to an Anthem MCA-325 Gen 2 amplifier for the fronts and other multichannel amps for the rest of the 11. 1 system. I wanted the 3 channel amp close to the front speakers for the shortest speaker cable runs for the critical L, C and R speakers and the MCA-325 is connected to the AVM70 with Mogami Gold XLR cables. The response times of the system are lightning fast and the AVM70 reproduces and places all objects with incredible accuracy - so much so it has surprised a few experienced listeners with its abilities. This is a definite "wow" factor each time I've listened to it, along with the perception of space and sitting in a theatre much bigger than you actually are. I was looking forward to the results ARC Genesis calibration and wasn't disappointed. It has powerful room correction abilities and very good bass management. It is ahead of Audyssey which in itself can be very effective. However it isn't easy to directly compare room correction software when using different AVP's because of other variables. In summary I think the praise heaped on ARC Genesis in forums has not been overstated and the intrinsic audio qualities of the AVM70 are even better than the high expectations I had for it. I think this might have been helped by the well matched MCA amplifier but I have had experience with enough AVP's to know this is special.

Hi Betty Boop, thanks for the check in. I purchased the MRX from original owner but I don't think there is anything wrong with the unit. I reached out to Anthem directly and they agreed the crossover arrangement looked odd and recommended changing. I've been doing a little more diagnosing and am wondering if my 80-200Hz nulls on front and surround speakers is being caused my a large room mode at my listening position. I've tried moving front left speaker forward about 30cm and MLP forward about 50cm and it does help reduce the null a little, but doesn't eliminate it. Am working on an acoustic treatment plan in my dedicated theatre room build (see signature for link) but haven't worked out how I'm going to solve the null issue. I'm all ears if anyone has any ideas? Short of crossing all my bed layer speakers at 200Hz (I have fairly flat bass response from 8-180Hz) I'm not sure how to fix.

I'm not sure how you measured the subwoofer response but if its the corrected output by ARC then you won't have a flat response to 200 hz because the bass for some speakers is cut off at 80 hz. After 80 hz, output from the subwoofer is consequentially reduced because there is no redirected bass from the 80 hz speakers. The first thing I would do is reset the crossovers to have some consistency. I haven't come across any room correction system where I have been happy with the all the crossover points selected by the software. Set those and then run ARC again. For example, I would set all speakers that can comfortably do below 80 hz to 80 hz and the smaller ones to 110 or 120 if the spec shows a reasonably flat response after that. I would only go higher if the speakers's spec shows roll-off at that point. I have been doing this for years with various systems and it gives me the most immersive and integrated sound The issue with the sub woofer attenuation by ARC might due to be the volume setting the subs are set to before calibration.

I was really joking about crossing over at 200Hz but if I turn my crossovers right up to 250Hz and measure pure bass response in REW or even with ARC it shows a reasonably flat response right out to 200Hz. Since my initial post I've turned my crossovers down to 120Hz and applied. I have large floorstanders that can run down to about 40Hz but I don't like to run them that way for home theatre use. I suspect ARC was turning the crossovers up so high given the large null I have between 80-200Hz on several speakers, which is still there after crossing lower. 1 hour ago, betty boop said: hi oz, good to hear reached out to anthem. no you definitely dont want your bed speakers crossed over at 200hz .. that is way too high and bass will be very localised and not too many subs are that happy working that high up in any case.... with nulls i usually look at couple of things.. nulls due to cross over and phase...which you can tweak at the sub.... but it usually only leads to some tweaks... the other way to fix boosts in corners and nulls in the room is bass traps but these usually tend to be have to be ridiculously huge to do anything so not usually much help... nulls are best dealt with with location of main listening position and position of speakers if can move them. you are not sitting in the middle of the room are you ? as that is typically where a null exists in most rooms... i usually aim for rule of thirds for placement ...so place yourself at 2/3rd room depth.. and move your mains out as much as 1/3rd room depth...moves speakers off walls reducing room gain and moving self out of the null... where is your sub placed ? and what cross over point are you running on it ? while eq can perform minor miracles its always best to get this kind of things sorted in first place so dont have to try resolve with eq... Thanks, I was talking in jest about a 200Hz crossover. Agree that would never be practical. Re room setup - I'm sitting approx 2/3rds into room per general principles and mains are about 40cm forward of my front wall which is about as far forward as I can go. It's not practical to move mains 1/3rd forward of room depth as I run an acoustically transparent screen in front that would be too close to my lounge. See below floorplan as guide for general dimensions and placement. I'm also running some very large bass traps (2m high x 2m wide x 43cm deep with 2m air gap behind) in my right side alcove. I've measured and they've done a good job to boost/smooth out response around 30Hz. I'm running four subs - two in front stage (middle and right side of room), one in rear right corner and then a HoverEze platform (4 x 12" drivers) directly under my lounge. The subs were placed after measuring 30+ positions in my room to determine best summed response. Subs are time aligned and run via a miniDSP 2x4HD with MSO calibration for best seat-to-seat consistency (very happy with my progress there). I've currently set a 120Hz crossover for all my speakers and LFE through ARC. It's really just the 80-200Hz speaker performance and some apparent reverb 800Hz-5,000KHz range that I'm trying to sort out now. I am wondering whether the listening position is causing my 80-200Hz problem and what I might be able to do to confirm and resolve? I have measured movements to my left main speaker and MLP (see below ARC Quick Measure for an idea) and it does improve the response, but not completely. Trying to find a balance between practicality in the room and as optimal performance/response as possible. Front left speaker - Default positions vs 30cm forward vs 30cm backward: Front left speaker - Main Listening Position (MLP) at default location vs MLP 50cm forward: Front left speaker - No new room treatment vs 50mm fibreglass panel at first reflection points (left and right side walls) vs panels at rear wall: 1
betty boop Posted November 19, 2023 Posted November 19, 2023 Sounds like you are doing all you can with locations and put a lot of effort into setup. Hopefully someone can help you with regards arc to help tie in for a better end result you are seeking 1
OzJustin Posted December 28, 2023 Posted December 28, 2023 Can anybody please tell me if users are able to assign individual ARC calibrations per profile on 20 series receivers? I was of the understanding that we could take multiple measurements and assign the ARC calibration per profile but that doesn't seem to have worked in my latest attempt. For context, I created an ARC calibration (using Measurement A) and named it Profile 1 and assigned it to various sources. This profile 1 calibration was to cover a three sub arrangement for music/tv. I was then attempting to run a separate ARC calibration (again using Measurement A as it doesn't appear to let you perform Measurement B in isolation through a separate measuring process) and name it Profile 2 and assign it to other sources. The profile 2 calibration was to cover a four sub arrangement for movies. Instead, it appears my receiver has uploaded the single latest ARC calibration to all Profiles (1-4) and given two profiles the name Profile 2. Does anyone know a good Brisbane calibrator/or even a friendly forum member with experience in Anthem products? I'm having lots of weird results (e.g. Anthem setting crossovers at 250Hz, bass response rolling off from 60Hz despite me setting crossovers at 120Hz etc) that are not making sense to me and would love to pick someone's brain.
betty boop Posted January 12, 2024 Posted January 12, 2024 seems like a massive watchout has been uncovered on the anthem avm90...now this is from Bonzo17 in the avm70/90 thread on avs, Because I was too distraught. I was 100% upset to my stomach and 100% pissed off at the same time. I decided after my original post that I would try to cool down before posting again. Nobody in their right mind would have wanted to hear me last night. As it is right now, I have not slept all night. I have just spent the last hour on the phone with Crutchfield and then Anthem tech. And guess what. They are both saying there is nothing they can do. Crutchfield has arranged to to have the AVM90 picked up for return. At the very least, the AVM90 fried the tweeter in my center channel, for sure. I'm not sure about the rest of my system yet. Sorry Yonettes, it was NOT user error. I'll go into more later, because I'm still making phone calls. But as important to my family as the Michigan game was last night, I missed the entire 4th quarter because I was crying. For no reason what so ever, while just laying on the couch with my wife watching the 3rd quarter, there was a 747 landing on my house. It was the loudest noise I've ever heard. I'm not sure if it was the white noise set up signal or what. It was so loud it was hard to tell. INSANE loud. Way louder than my -15 max volume setting. There is no doubt in my mind that the max volume setting does NOT limit the volume of this issue. The remote was 10 feet away. My phone was on the coffee table. The TV from DirecTV had been running just fine since about 6:30 earlier. It was out of the clear blue. It scared the crap out of both of us. Even my wife was nervous. I'll post more later because I've gotten zero sleep, and I'm currently skipping work to try and make phone calls. I'm just so flustered and upset I don't know what to do. My speakers are from 2006. I love them. I'm more upset now than when my beloved sports car got rear ended. Replacing speakers isn't really an option without spending more money than the 90 cost. Fixing might be a possibility but I'm not sure. My TV cabinet is custom made to fit my center, so I might have to completely redo the cabinet. And like I said, it may or may not just be the center. If its other speakers holy crap, I just don't know. Holes and wires ...... So I spent a bunch of time (I have been researching processors for 10 years), testing with the Marantz, spending a lot of money (for me) and everything else, only to have the 90 ruin things for me. I'm already not myself because of my Mom dying back on November 30th, and now this. I feel like my world is crumbling in around me. Crutchfield is taking back the defective 90 tomorrow. Anthem is currently not accepting any responsibility. So I may be on my own on an island. 1
betty boop Posted January 12, 2024 Posted January 12, 2024 (edited) since his posting others owners have come forth with the same experience ... all from AVS owners thread, rhale64L7 I have had in the past a loud static like sound after I ran ARC and first played a song. But in one of the recent firmwares that was fixed for me. That's exactly what it sounded like. And yes it goes to max volume. Right past the set max volume. I have bullet proof speakers apparently because it happened to me two times. And then we avoided the full volume one other time when my grandson accidentally stepped on the volume on my remote. That was before I had set a maximum volume. ExdarkxH with a kef blade setup... Okay so thats happened to me multiple times. Like honestly 3 times now I blamed my wife last time thinking she touched the volume control on anthem remote. But thinking back after reading your post, and knowing how the app works, theres no way You have to hold and drag the volume across the circle. And it instantly withing 1/4 of a second went from -35 to max volume it was so loud i thought my hearing might have been damaged now im starting to realize its the avm 90 Bill-99 There have now been a number of incidents reported in this thread where an AVM goes to max volume, Bonzo17 being one of the latest to encounter this. At the very least, it's annoying. Sometimes equipment is damaged. The biggest risk, however, is potential hearing loss -- something definitely to be avoided because it's a one way street. NanoRish Hi Bonzo, Just catching up on the topic and sorry that you had to go thru this. I went thru a similar experience with my AVM 70 and using Analog input (Which due to sensitivity would be around 16-18DB louder, Anthem claims to have fixed it but Its too traumatic for me to ever try that again), one accident slide on the volume keypad (even though I had max volume set to -10DB) resulted in blown tweeter on my B&W 805D2. It was before I knew that you can set the input trim on each input to further lower the signal. It was also during the Covid so B&W factories were shut down and it took me close to 4 months to get a replacement tweeter (although it was easy to replace it myself). OldMike2 Bonzo Sorry to hear about your experience, I had a similar event two years ago, in my case it was caused by a defective HTPC Intel NUC HDMI firmware. I escaped with no speaker damage fortunately but it scared the crap out of everyone in the house and made my wallet shiver. FreMo I already had this twice when playing a blu ray. Fortunately no gear damage for me. Since this date I'm shaking each time I press play... AVS community have been amazing rallying together with speakers/components to replace the blown one etc... anyways something to watch out for .. not sure the cause but what ever it is hopefully anthem gets on top of it too...

Dokken Posted January 13, 2024 Posted January 13, 2024 NAD Avr's had a similar issue years ago. Not sure what the current NAD Avr's are like!?! Hence the reason why I only recommend Denon and Marantz AVR's to family and friends. 1
TP1 Posted January 13, 2024 Posted January 13, 2024 People should learn to take what is said on AVS forum with a good deal of scepticism particularly from people who don't seem to know a lot about what is going on. Firstly one of the posters said it was his HTPC that caused the problem so that is irrelevant to the Anthem. Another talked about the sensitivity of the app. Seriously? who hasn't had an issue of app sensitivity with a range of equipment? I would not take the poster's word for what has caused a blown tweeter - blaming it on the preamp is a first . Just ask any tech experienced in investigating causes of blown speaker drivers.
GaryT Posted January 29, 2024 Posted January 29, 2024 Hi Folks, Anyone have a HDMI board for an MRX720? or possibly a unit with a dead audio section but potentially working video board? I bought it used about 2 years ago and it was effectively new in box, most things still sealed but of course well and truly out of warranty, the financial situation has changes dramatically since then so I'm not in a position to buy a new one. My 720's main HDMI output and one of the inputs have decided to die, and the remaining secondary output not only doest support the same video standards but it drops out to a green screen occasionally requiring a reboot, so I've decided the HDMI board has failed. I've tried the resets, reboots, full factory reset, new cables etc, but no dice. I know these have become unobtainium, but Surely someone has a parts unit with a dead amp or psu but potentially good video board that might save me? are the video boards on the 520 and 1120 the same? anyone have one of those perhaps? In the meantime, I'm also looking for an affordable basic receiver with 5.1.2 atmos and HDMI 2.0b (Dolby Vision support) as a temporary stand in in the mean time, minimum of 3 HDMI inputs and 2 analogue audio inputs. Cheers, Gary
Guest Posted January 29, 2024 Posted January 29, 2024 @GaryT If you still like Anthem, maybe this, as a replacement? https://www.selby.com.au/price-promise/anthem-mrx-540-av-receiver-black.html You will need add a 2 channel amp to do Atmos.
GaryT Posted January 30, 2024 Posted January 30, 2024 I came across that in my searches and it is a good deal, unfortunately it would require an amp for the height channels, My only "spare" amp is a Krell FPB200 which would be immense overkill and I'm going to have to sell it just to fund the replacement. without selling that amp my budget is only $500. Gone are the days where I could just use any issue as an excuse to upgrade, I have to pinch each penny these days.
GaryT Posted January 30, 2024 Posted January 30, 2024 It also seems to have taken out the HDMI port of my TV that it was connected to.. so that's another thing that needs to be looked at. thankfully that TV has other ports but something went catastrophically wrong here. thankfully that TV is only 14 months old so I have Australian Consumer law on my side for a repair or replacement of that.

Did you have a nearby lightning strike? They can cause induced currents in cables and blow HDMI ports. Might be a contents insurance claim.
GaryT Posted January 30, 2024 Posted January 30, 2024 I've been looking into that too, there have been some incredible storms around here lately.
