A Nice Home Theater Processor That Makes Me Drool!

Who is this blog article for?

Anyone who is into home theater electronics and those who understand home theater terms such as a home theater receiver, a home theater processor, and eARC. This article is unsuitable for blind users who do not have eyesight.

A Cool New Home Theater Processor!

I received an email from AVSForum about a 9.4.6 Home Theater At CEDIA That You Definitely Don't Want To Miss (that's 9 speakers near the wall, 4 subwoofers (2 front, and 2 rear subwoofers), and 6 ceiling speakers) and I came across a processor that is used at CEDIA called StormAudio ISP Elite MK3, so I went to that page andโ€“wow! A multi-theater processor!!!

Okay, so what does that do? Does the ISP processor... (Interrupted by the "I don't care about cookies" web page as I type. A browser extension in Firefox about getting rid of cookie warnings or cookie notifications in websites opened up a new tab after updating a browser extension as I type. Now I'm getting off-topic. Thanks to you, browser extensions!)

Hah... ๐Ÿ˜† Let me get myself back in control of my moment as I write my blog post. Because that cool new home theater processor interests me a lot! ๐Ÿคฃ๐Ÿ˜€

Okay, so what does that new home theater processor do? Does the ISP processor let me have multiple theaters? Yes! That's having two home theater processors in one processor! Okay, let me explain. Most people that have a surround sound system typically have a home theater receiver with amplifiers built-in. A processor does not have an amplifier, so it needs an external amplifier. An ISP processor can have up to 32 channels of audio. That's 32 speakers. What!? 32 speakers!? Yes. "But you don't need 32 speakersโ€“let alone 4 or 8 subwoofers for a dedicated home theater room," you exclaimed. That's true, but that's not the point. Think about AMC Theatres. If you have been to a movie theater, you know AMC Theatres has so many auditoriums, right? Think about just one device that can connect to 16 speakers per theater room. Actually, commercial movie theaters do have multiple rows of surround speakers. Each row of surround speakers can be located to the left and right side of the room and can surround multiple rows of seating. Of course, that can be done using a StormAudio ISP processor, but that's not what I am interested in.

What piked my interest is the multi-theater feature of the StormAudio ISP MK3 processor. This would allow me to assign 16 channels of audio to a dedicated home theater room and 8 channels of audio to my home office/gaming/studio room. A home theater processor has two HDMI outputs. One HDMI output is linked to the 16 channels for the home theater room. Another 8 or 16 channels of audio (depending on the modules installed in a processor) can go to my home office/gaming/studio room. So people might be thinking "is it possible for a home theater receiver with an integrated amplifier to have 32 channels of amplification?" The problem with that is, the home theater receiver's power supply is very limited in terms of the amount of current that must be pushed from an electrical outlet to the speakers. The receiver can get so hot to the touch even if nothing is playing. That's why going with external amplifiers is better when playing at high volumes. A dedicated home theater room needs to be connected to a dedicated circuit breaker in order to provide enough power to the speakers in a dedicated home theater room. For a computer room, I may not need a lot of power, so a 700w amplifier going into 7 channels (that's 100 watts each per speaker) is more than enough for me.

Although the price of the StormAudio ISP MK3 processor is sky-high, for me, that is similar to buying two cheaper home theater processors, but the cool thing about this is I could have more speakers in a dedicated room and still have leftover for the speakers in the computer room. And I could control the processor to show me a different video source going out to HDMI 2, which is the connector going out to my computer room. If I want to see what's playing in a dedicated movie theater from a computer room, I can do that because the processor acts as a hub. Sure, if I could find a multi-theater processor at a lower price than the StormAudio, that's great, but I get what I pay for. Right now, the MK3 only supports HDMI 2.0, which means I cannot game at 4K (3840x2160) at 120Hz and my TV (Samsung 43" QN90B) supports HDMI 2.1.

I have my PC connected to my TV, then from the TV to an eARC HDMI audio extractor, and then to my Denon AVR-X3400H which does not support eARC. Basically, eARC allows 5.1 or 7.1 surround sound audio to come directly from the TV and the audio passes into a receiver's HDMI out for the receiver to process audio information so that the sound can output through the speakers. But because my home theater receiver does not support eARC, I use an audio extractor (that I linked above) in order to supply audio going out to my receiver. Here's how it works:

  1. "HDMI Out" from an audio extractor connects to my Samsung 43" QN90B's HDMI 3, which lists "eARC." Connecting an audio extractor to HDMI 1, 2, or 4 in the back of my TV won't work as those HDMI ports do not provide eARC support.
  2. "HDMI Audio Out" connects to my Denon AVR-X3400H's audio input. This allows my receiver to process audio that came from my PC that hooks up to my TV's HDMI 2.1 inputs.
  3. "HDMI Input" from an audio extractor connects to my Denon AVR-X3400H's HDMI Output. This allows me to select HDMI3 on my TV. Any video going from my receiver to my TV passes through my audio extractor's HDMI input.

And that's all there is to it! In short, my PC connects to my TV via an HDMI cable, the TV connects to an audio extractor, and an audio extractor connects to my receiver. An HDMI audio extractor avoids having me buy a new receiver. Think about this. Back on late 2018, my Marantz SR-5008 was having issues and the audio continues to make squealing noise after the outbreak of Hurricane Michael. Since January of 2019, I wanted a new receiver. Should I buy a Denon AVR-X3500H which supports eARC or should I buy a Denon X3400H which does not? Back around August of 2013, I bought a 4K-ready receiver, thinking that $900 would give me a much better sound compared to Marantz SR-5007, which was a discontinued model. That's why I bought myself into that "$900" hype! Bad! Bad mistake! So let me ask you this. Would you spend $300 extra just for eARC support? Me? I don't think so. I bought a Denon X3400H just to save $300 in the process. Sure, Amazon mentioned that X3400H is a discontinued model (yes, it "was" as it's past-tense, but let's forget about the tenses for now), but I bought it anyway! Why? So I can quit being a fool! The sound character is the same regardless of whether it's a 2010 model or a 2022 model!

Of course, I've gotten way too far off-topic from my article, but the point is, I'm going to wait for ISP to come out with a new processor that supports HDMI 2.1 such as 4K at 120Hz. 4K at 120 Hz would last for a very long time for me. Maybe a decade? Even if HDMI Alliance (or whatever it's called) upgrades to 8K (a resolution of 7680 by 4320) at 120Hz? Okay, hold on a minute. Today, I don't think modern graphics cards can even handle 4K at 120 frames per second or even at 240 FPS unless people play older games or turn down the graphics settings. I mean, I'm talking Cyberpunk 2077 that can push even an NVIDIA RTX 3090 so hard that gamers can't get more than 90 to 100 frames per second. So, HDMI 2.1 will be with us for a very long period of time. Well, I'm pretty sure that games such as Cyberpunk 2077 could run the GPU (graphics processor unit) down to 20 frames per second or even lower. ๐Ÿ˜‚๐Ÿ™‚

Anyway, one day I could save up my money for an awesome StormAudio home theater processor. One day. That is, if I could get into network engineering and make a whole lot of money (I am Cisco CCNA certified as of October 2021; I am CompTIA CySA+ certified as of August 23rd of this year, which renewed my CompTIA A+, Network+, and Security+ certifications).

My Dream Home of the Future: Computer in Server Closet; KVM in Home Office; Home Theater

I have been watching a couple of YouTube videos of people who want a computer in one room (such as a wiring closet) and a keyboard, video, and mouse (KVM) in a home office. To give you an idea of what I'm talking about, I want to post links to YouTube videos.

Embedding YouTube or Odysee videos will insert a tracking cookie in users' personal computers. As a citizen of the US, I need to follow GDPR if European visitors visit my website. I don't like and want to talk to lawyers to be honest. ๐Ÿคฃ๐Ÿ˜€

As for the video from Linus Tech Tips, I would much rather have a couple of computers rather than single computer that can house a couple of virtual machines running desktop OSes such as Linux and Windows just to make it easier for me. So yeah, a virtual machine is a computer within a computer that can serve different purposes such as running Ubuntu within Windows using VirtualBox or by running Windows OS in a Linux host using KVM or Xen.

So, I have an idea of my own. When it comes to building a house, I would like to wire my future house for Ethernet and HDMI connectivity. The computer will be in a wiring and server closet and my essentials such as my mouse, keyboard, monitor, audio interface, and a couple of others will be in a recording studio/home office room. So here's what I'm thinking of buying in the future:

One concern I had with USB over Ethernet is latency from the audio interface to the computer over the Ethernet cable. However, one look at the images and answers to questions tells me that latency over Ethernet cable should not be a factor. That way, I can have my computer fans spin at max RPM in the server room (well, maybe not too loud) and still have complete silence in my studio/office with sound proofing and acoustic panels.

Oh, here something that I would like to show you (for those with eyesight). It's a home theater room made in Blender.

This is a rendering of my home theater made in Blender. It has a 200" projection screen, 7.2.4-channel speaker system, and comfy seats with cupholders in between.

My dream of a home theater will be a lot simplistic than that with flat ceilings with no light strips in between them. A home theater will be in a basement. Speaking of home theater, I could patch my home desktop over to my home theater while in the server closet if I want to watch YouTube/Odysee videos. How cool would that be if a house can have a central computer core just like in a starship such as U.S.S. Enterprise D or U.S.S. Voyager? Speaking of starships in Star Trek, do you know that a central computer core can span over several decks? Actually, a starship can contain two or more computer cores. My house might have only a single central computer core with a couple of rack-mounted desktops and servers as part of a homelab! Here is an example of a homelab shown in a YouTube video.

As for rack-mounted desktop PCs, I'm thinking of Rosewill RSV-L4500U Rackmount Server Chassis and put them inside a StarTech.com 42U Server Rack Cabinet. Oh, sure the rack-mounted enclosure costs more than an open-frame 42U rack, but to me, it will look a lot cleaner by having an enclosure. Now if only there are 5U or 6U rack-mountable computer cases so I can fit a tall heatsink such as Noctua NH-D15 or Scythe Ninja 5 heatsink. Now keep in mind. I do not care about the looks of computer components. No RGB fans, no tempered glass side panels from the likes of Lian-Li 011 Dynamic XL or even from Phanteks line of computer cases, no nothing.

Why!?

Out of sight, out of mind.

That's my mindset when it comes to computers. If you watch Star Trek, you must know that Captain James T. Kirk does not look at a central computer core every single day while he's in his quarter or in the bridge! No Starfleet officers should care about how cool computers look as long as they perform their jobs! Sorry elite gamers, but I do not like the market the computer case manufactures are targeting. Go look at how cool your computer looks while you are failing your Cisco CCNA course because hey! All that cool RGB fans and that NZXT Kraken Z73 cooler of yours are so much fun to look at! ๐Ÿคฃ

As for me? I'm excelling in Cisco CCNA course! Why? My Silverstone FARA R1 computer case only has a plain side panel and is free of distractions. It's unfortunate that a computer case with a plain side panel is unavailable. But I have it! However, the limitation I have is I cannot take the case feet off so I can fit on top of a rack-mounted shelf.

Oh, did I meant to taunt you for having all that cool tempered glass computer case with all that RGB gizmos? Get over it! Seriously. I know you've been playing games 24/7 while you look at how cool your computer looks. Okay, okay. I'll be nice to you elite gamers! ๐Ÿ™‚

If you want to get into the world of homelab, Lawrence Systems and Learn Linux TV has done a couple of videos for setting up different aspects of homelab such as Home Assistant, storage server, firewalls and switches, Linux, Ansible, securing your lab, and so much more. Check out the playlist on YouTube and enjoy! Any desktop PCs will be part of a homelab as well. And yes, RAID is not a backup solution. In a RAID 5 setup with 7 hard drives (6 for data and 1 for parity), if one drive fails, swap out the hard drive as soon as possible. But if two drives out of 7 fail, you lose all the data inside the hard drives.

Now here's a question. What about entertainment devices such as NVIDIA Shield TV, and PlayStation 5? These devices can sit on a rack-mountable shelf and can be patched to my home office room using an Ethernet-based USB extender. For HDMI, I can make use of Anthem MRX 740 for my home office room and use HDMI Zone 2 Out to pass HDMI audio/video signal to Anthem MRX 1140 receiver, which can go to the home theater room. What I've learned from a thread over at avforums.com is that the main receiver (MRX 740) will pass audio/video signal to another receiver and plays no part for processing A/V signals.

What that means is I can independently select a source in the second zone while the first source will remain intact in the main office room. Just tell Home Assistant to switch to NVIDIA Shield in the second zone of MRX 740 receiver, and Home Assistant will do the rest. Whatever is shown in MRX 1140 for the home theater room will reflect what was shown from MRX 740's HDMI Zone 2 output.

So yeah, centralizing desktop PCs in a wiring/server closet is my dream of the future! Centralize all the desktop computers into one 45U server rack! ๐Ÿ™‚
