@iFi audio I have questions regarding your products and my use case for them with one of the devices I have here. Sometime ago relatives of mine gifted me a handheld console that is modified with a capture card, for a while now I've been testing the capabilities and exploring my options when using said device, this device utilizes a micro USB 2.0 connection for the video capturing tasks, however the capture software also has capabilities to handle audio digitally alongside video capturing. I've tested this aspect of the software out and for the most part it sounds fantastic, the only issues however were the popping and buzzing from certain scenarios (results may vary from software to software, audio is not implemented the same across every title out there). Unfortunately there is quite literally nothing about my situation on the internet, partly due to the device I have being a bit of a rare commodity now a days, not to mention most individuals who do have such devices don't really do a lot of extensive research or put forth the effort to really master their initial setup when using such devices, I've been going in and testing things out by myself as a result of this for nearly an entire month now. I've asked around a few places for help, and so far I have yet to get anything that really helps my situation.
Before I discovered your products, I actually have been testing around using my line-in connection in the back of my machine, this is where I discovered ground loop noise and power noise for the very first time. For some context, I never had a nice setup where audio systems are concerned most of my life, my computer was a graduation gift I had received a few years ago, and I barely just discovered that my system quite literally has a decent sound system built into the motherboard, it's a "Creative Sound Core3D with SBX Pro Studio Audio Suite" (at least according to the website that lists my motherboard features), and I currently control that using the Sound Blaster Recon3Di software, needless to say I keep finding more reasons to cherish my rig even more. Anyways, this is what started my search over ground loop noise and power noise isolation to begin with, and with some small digging I did find a solution for line-in, committed to a purchase and gave that a whirl, for the most part it works well, but there is still some power noise in the background. This made me think, if 3.5mm audio jack solutions exist for this, maybe they have something for USB cable connections too, clearly my system has some ground looping noise and power noise issues, so I figured why not try and see if I can fix my original situation, and sure enough I discovered USB related solutions, though interestingly not very many solutions exist for this, your iSilencer+ came up in the search results, and not long after I found out about the iDefender+ (black and red USB devices respectively). I did lots of reading into both of these device's capabilities and even looked at the product reviews, at least on Amazon so far, I've read nearly all of them, the good and the bad, most of the bad seem to be about DACs being killed or "bricked" when using the iDefender+, at least whenever a 5V connection is supplied to it through the USB-C port, I'm not sure why that would be happening, I personally don't utilize a DAC, though I have looked into a solution that does the opposite of a DAC, that being an ADC of sorts to try and achieve similar audio handling to that of the capture software, but using my line-in connection instead (so far I am not able to find solutions for this part, so I'm kind of stuck here on that). You seem reputable clearly and the fact you actually talk to folks in places like this is actually quite surprising, most businesses/corporations don't really take the time to really discuss about their products on forums and such with other people, so I have to give you props for that. As I stated earlier though, I have a questions regarding your line of products in use with my device situation.
1. Provided this hasn't ever been done before that I currently know of, is it safe for me to use the iDefender+ and or the iSilencer+ with a device like this, knowing that both video and audio handling is occurring through the micro USB 2.0 connection (might I add there is a 264Mbps connection when it's in use, so I have no clue if one or both of these devices will make this connection bad or not either)? While I'd like to think the whole "killing DAC" reviews are merely errors on the buyer's part, it's not easy to replace a capture device like this provided it's custom made, killing this capture card would be devastating, financially speaking I couldn't have afforded one of these devices myself, and these are not cheap to acquire. I only ask as a safe measure before I make any major commitments to buying one or both solutions.
2. I looked at the whole "Inject 5 volts of clean power via the ‘separate’ USB-C port" portion in the iDefender+ product page, it seems straight forward, but I know very well that not all things said are as simple as they seem, sometimes there is a catch, and that usually comes in the form of having to use something specific brand wise alongside solutions like these. Am I allowed to supply my own cable for use with this device (fitting within the voltage parameters the page mentions), or do I need an expensive cable solution of sorts? With the first question in mind, I again don't know how safe this would be with a capture card connection at stake here.
3. This might seem a bit of a funky idea, but with what both the iDefender+ and iSilencer+ can do, does combining both provide any benefits when in use together? Is there a certain order that these should be connected for the best results if they can be combined?
