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

Nope, dont believe them, They are my kakis and just trying to bully me :rofl: thats not the reason, Fans never cause such issue and I am a hard core electrical and Electronics Engineer and I run them through separate external power source. I can challenge that it will have ZERO negative impact on any electronics device, I encountered this issue after adding an Jailbroken Oppo 203, whereby I had to choose the sound format to sometimes from dolby Atmos to 2 channels and then change back then works fine. This is an issue with Jailbreak Oppo 203 players. I had a non-jailbreak 205 and it never behaved that way.

I’m just curious, why are you playing in 60hz? :thinking:.

  1. I would definitely connect the oppo main hdmi out to my projector/TV & secondary hdmi out from oppo to my avr/avp.

  2. If I rmb not wrongly that oppo has this issue on the audio playback. Yes you have to set either back to Dolby digital then back to Atmos in oppo. I believe it a well known issue. Even oppo 205 has the same issue.

  3. I would never tamper to open up and install something additional on my avr/avp. Even though if I have the experience or knowledge.

Just my 5cents.

The Nvidia Shield is set to Auto and it will change the resolutions automatically to 60hz when there is a youtube videos. Its set to Auto in both Oppo 203 and Nvidia, I prefer it that way cause not all videos are done in 24hz

  1. Yes, but the AVP/AVR are designed to receive video audio resources from various sources. I prefer to use AVP cause I use that as single source for all my video devices.

  2. No, there are 2 oppo jailbreak devices had this similar issue. one was with our Friend here and another one is my current one both are jailbroken. My Previous Oppo 205 was not jailbreak and it worked flawlessly. If I remember corrrectly, in my Vanilla Oppo 205 i have not even changed it once from dolby atmos to Digital and then back to atmos :slight_smile:

  3. Agree, but It doesnt do any harm rather will benefit the device since the day 1 and it was working way better than before adding fans. This HDMI started flickering only when I started using Oppo 203 changing dolby atmos to digital and back to atmos :upside_down_face: Afterwards even while using Nvidia, it creates the same issue. It lookes like Oppo killed my Arcam HDMI board.

  1. If it’s make you happy, why not.

  2. The same issue be it jailbreak or not jailbreak.

  3. oppo too strong for arcam to handle :smirk:

Hahha True True, I have sent for repair and lets see what they say, change board or refresh the board.

From what i observed, the products itself don’t have much issues, it mainly cause by users issue… where got people buy new product open up the cover and do something on it, and all this are brand new with warranty covered. Than don’t like sell it to another buyer???.. if people know what you had done who will really buy your items…
Do your thing right in the first place… don’t just blame the product you buy are not good…
These really happen to the person we know…
Buy new subwoofer and replace a driver because the original driver does not perform to his requirements and then go on telling everyone he did something great after changing the driver…

Better back to Anthem discussion…

You are not missing much as DTS Neural X upmixer is comparable to Auro 3D in Anthem’s case. This is based on my personal experience. But yes, I DO SINCERELY hope that Auro 3D will be added in future update but I’m not holding my breath for this.

I am hoping for the same too. But my honest feedback (in my opinion), I have compared DTS Neural X upmix in Marantz and Arcam and Denon with Auro3D and its not even close to what I feel in Auro 3D upmix. Hope Anthem will adapt this in future updates which will blindly make me to buy this next second :slight_smile: Lately I stopped using DTS Neural X and until now I never use it.

If you are really good at over looking at manufacturers design, why in the first place you have bought the Arcam. You really make others want to question your abilities of choosing a good products…

Don’t have to proof anything…the way you comment people already doubted your abilities…
Please just concentrate to discuss Anthem product in this thread.

Just concentrate on Anthem discussion…

AVM 70 and 90 use the same casing which have the vent holes, Arcam don’t have it.
It prove Anthem has good ventilation over Arcam.
if you put AC Infinity cooling fan on top of your device, it has no use.

A small fan is placed at behind front panel, I don’t know what is the purpose. Is HDMI board placed there?

Anthem AVM90 has a great ventilation. The small fan inside the Anthem (mounted on the Display PCB Board) its actually blowing towards the HDMI and audio Voltage regulator board to make the internal components cool. I saw in avs forum that some owners had mentioned that its noisy. Havent experienced it so far. If its noisy they could be using an high speed fan.

Arcam don’t have the vent holes so hot air trap inside become hot air blowing hot air likewise Anthem have vent holes side and top sides.

You are correct, so I have placed two fans, one blowing exactly towards HDMI, and another one on the bottom there is a air vent and it just suck out the hot air out from the arcam unit. Arcam is also aware of this as I had escalated this issue to them already and hence they are very supportive. Later will share photos, I have now sent it for replacing the HDMI board.

May I advise that you create any thread for Arcam and share your views and experience so other Arcam user can also share. Thanks
