Storms, power spikes/surges and HDMI ports in devices definitely do not mix. In my experience they are the first thing to go, and HDMI issues related to local power problems may not be covered under manufacturer's warranty. Even plugging/unplugging HDMI cables with the power on can and may cause faults. Just a month or two ago one of my customers reported that his Marantz 6015 wasn't outputting HDMI signal to his TV. First question I asked was 'have you had any storms lately?' He said 'funny you mention....' He ended up claiming against his home and contents insurance.
GaryT Posted January 30, 2024 Posted January 30, 2024 I just sent my insurer an email about that one, the last time the system worked was the Saturday, then that night or early the next morning was a severe lightning storm, and I have several 20-30m Active HDMI cables threaded through the home for AV distribution. Always a bugger, never had any real lightning damage and honestly the receiver has been playing up since the Christmas storms a few weeks ago too, this one might have just thrown it off the edge. By the way, we used to do a little bit of business with VAF, you used our equipment feet for years on your subwoofers among other small items. 1
ans Posted February 19, 2024 Posted February 19, 2024 I am an old DTV forum member and looking at buying MRX 740/1140. No need for 1140 yet as I will be running single zone with 5.1 setup for now and I can't find any other difference in spec related to video/sound quality. Happy to hear your thoughts. Is there any group buy for MRX 740 like the old days? The retail price seems quite high.

Is there any group buy for MRX 740 like the old days? The retail price seems quite high. Was also in DTV. The big difference is in the number of amps. I suspect the 1140 has more room correction filters, but cannot confirm it. Should be no difference in video (no processing, only pass through) and audio. And group buys not allowed as a general principle.
GaryT Posted February 19, 2024 Posted February 19, 2024 the MRX740 4k models pop up on the second hand market for quite reasonable prices, and they are functionally identical to the new ones as most home theatre and hifi users aren't using hdmi 2.1. As far as I know the processing and room correction on the 740 and 1140 are the same, the only difference being the amp channels and if they are anything like the 720 and 1120, the 1140 would have a better quality power supply that not only supplies more power for those extra channels, but offers a noticeably lower noise floor.
GaryT Posted March 28, 2024 Posted March 28, 2024 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. So I said no, it's either repaired for the price I was quoted or you return it to the original state and give it to me with just the audio working, as it was when I dropped it off, and a full refund of the repair price paid. I also paid a quotation fee before that but they can keep that. They are refusing to let me take it back now and the state that it is currently in is worse than it was when I dropped it off, no audio at all. I have no amp at all now and a hole in my bank account. I will never use them again, I will be fighting this.

Sorry to hear situation you are in …$1700 seems extreme ? can I suggest posting in the recommended repairer thread as folks should be aware of this. Not good at all !
GaryT Posted April 14, 2024 Posted April 14, 2024 My issue with them wasn't even the cost, it was the fact that when they called saying it would take more work than originally quoted they said some extra parts were on the way as the ones they were sent "were acting a bit oddly" and it would be no problem at all, just a bit of a wait. not a word about doubling the cost of the repair until they had it running and called to say it they needed another $800 before i could collect it. Well I begrudgingly paid the fees (they wouldn't budge on cost and they wouldn't refund me to go elsewhere either) and the amp was repaired, but no IP address, no status lights on that connector, no wifi, hmm.. now I find they seem to have damaged a ribbon cable that connects the IP control board that connects to your network via Ethernet or Wifi. That is not really necessary for regular functions but it is needed for IP control integration (which I use as my main control method) Music streaming (don't care, I have other gear for that), but most importantly uploading room correction via Anthem Arc Genesis software which does not run on the device itself like some other receviers, but on a computer that then uploads the data to the receiver over LAN. They seem to have cracked the ribbon cable at the connector end while changing out the boards they replaced and likely didn't test the IP functions at all, because.. who would? Now I've taken some photos showing the clearly damaged ribbon and I have to wait and see if they try to tell my that it was always like that, or if they try to say it will be another $700 to replace that as well. I have sent all the paperwork to my insurer to claim back some of the costs, but I still wont use AV Digitech again and I cant see my next receiver being an Anthem despite them having features I would miss. I should have contacted Chris at Totally Technical, he doesn't do a lot of consumer repair work anymore and only takes on the jobs he wants to, but at least hes honest and works carefully. In other news, does anyone want to trade a cursed and mostly functional MRX720 for a slightly more working and less cursed 5.1.2 receiver? 1 1
GaryT Posted April 25, 2024 Posted April 25, 2024 Continuing on this saga, I've decided I'm going to replace the Anthem entirely pretty soon, The repairers are no longer helping. It's going to end up in landfill unless someone wants it for a few hundred or something. Likely it will be replaced with something simple and better value like a Marantz cinema 70 with a couple of cheap power amps plugged into it for the front channels.
Trevm Posted May 5, 2024 Posted May 5, 2024 Hello. Just a general question about ARC via Anthem. The projected correction sweeps with ARC look nice and flat but when doing a quick measure the results are nothing like what it has projected. Is that a normal outcome?
GaryT Posted May 7, 2024 Posted May 7, 2024 (edited) ARC doesn't re-read the room after applying corrections, so it cant give you an accurate reading of the true response, it may try to gain a frequency to correct a dip but if its a null due to the room modes that cannot be corrected that way, so it will remain and even get stronger after correction. Since if you have the gear to re-measure with REW, keep testing and tweak a few times to work out what is correctable speaker response and what is uncorrectable room response, then look at how moving speakers, furniture, listener and treatments can further improve things.

michaeldarren79 Posted January 7 Posted January 7 Anyone gone through the process of upgrading an AVM70 to the hdmi 2.1 board? What's the process and cost?
