@@jazznelsalica2275 If you just want to use it as a mixer you can plug the usb cable into a 5V charger or battery pack instead of powering it from a computer.
Nice video, I have a question for you about the Loop Back. I do video interviews and use Streamyard (It's like Zoom) to do so. I use a Behringer Q502 mixer (which I love) but I have an issue when both me and my guest speak at the same time. One of us is muffled and I cannot figure out how to solve it. I'm assuming it's because the guest's voice is coming from Streamyard, through my mixer and then back to Streamyard. If I had this device, according to what I'm understanding from your video, I could stop the guest's voice from going back to Streamyard, but I can still hear them? In other words, only my voice would be going back to Streamyard. (I call it a reverse mix-minus,) Is that what the Loop Back thing does?
I get quite a lot of pops when I'm running this on my linux laptop on AC power, regardless of the buffer settings I use. No issue on battery power or when I'm using it with my desktop. I would blame the laptop's power circuitry but it has no issues running my other audio interfaces, even ones based around the same PCM2902 IC, so I'm guessing the Q-12 is just more sensitive to any power issues the laptop has. I notice the same popping on some other reviews for the Q-12 (the same popping/clicking can be heard in Dave Soltura's videos on the thing) so I don't think I have a defective one either. Any ideas what would be making it more sensitive to unstable (or unfiltered maybe) USB power? Any cheap fix ideas? Also regarding your gain issues, on my unit pressing the REC button down allows that third pot (the red 'MAIN' one) to control volume of the audio coming through over USB. Is this not the case for you? In your other video you say it does absolutely nothing for audio going to the ADC but maybe that got changed in later revisions, but from the text on the button it seems it'd function the same way.
Thanks. Just stumbled on this video after stumbling on the Rode headset holder thing. Great video thanks. Both mics sounded great. Nice low end from the big Shure capsule. Didn’t know you could go straight from the filmmaker into the iPhone. Picture looks great. Nice setup….thanks!
To connect the filmmaker to the iphone i use a y adapter that splits the mic input and headphone output. The y adapter is plugged into the apple lightning to 3.5mm headphone adapter.
@@Chris_Grossman Can you tell me how you connect the shure to the rode transmitter please? What is the termination of your shure headset, and how do you adapt it to the Rode input? Cheers
Thanks for detailed instructions. I consider buying a headset mic for the similar reasons and I already have Rode Wireless Go. As for compatibility, I've seen info, that SM35 uses phantom power. So I guess this conversion will not work, at least tip-shaft variant.
There are two versions of the SM35; the phantom power version with an XLR connector, and a TQG (TA4F) version. The TQG (TA4F) version should work with this procedure.
Chris I need your help. Mine works fine with windows but I'm getting a weird noise /feedback when I use it with Mac. Any advice ? I have a 2013 imac and a mid 2009 imac same issue with both. Nasty feedback
@@Chris_Grossman Actually there's no setting for that as it seems hardwired into the device , but thanks to your video I figured pin 39 MSEL (Mixer) if set to Low would turn off Direct monitoring , is that true ?
Sorry, you're hands were obscuring what the first knot actually looked like. I was looking for the version involving what some call a lark's head. Been using it for years.
I figured it out. It's an interesting knot. Seems equally as fast, or more so, then the lark's head method. But, having looked at it, the lark's head method can be ratcheted tighter than a cable tie.
@@davidvelozee Thank you for the spec. I've been looking these up. Yes, all of the aircraft specs I've looked up call for a clove hitch with either a reef knot or surgeons knot to lock it. The mil. spec. I found also allows a two-strand version for lacing with a larks head followed by however many marline hitches are need. But, then there's a finishing hitch that I haven't gotten the hang of. This two-strand method is the one most like what I learned in telephony wiring. Thanks again.
@@TesserId I’m not sure what type of knot this is, it seems like 2 knots are getting “combined” to achieve the same thing. It is indeed very effective! I was having trouble with the standard method using 22AWG silicone wire, the “locking” knot kept getting undone! This knot seems to work better, though I’m not sure why! I did however add another half-hitch. And I like the solder cut. I couldn’t find what the other locking knot names were, so thank you for that info! For finishing up a long lacing run, it’s usually the same as the start; clove hitch and locking knot. But I’ll have to look it up…
I wanted to like this unit but unfortunately it failed simple testing. I just wanted it to power a Dayton EMM-6 Condenser Mic for car audio tuning. I did not get consistent measurements with an RTA. Th mic would start out fine but the lower frequencies just dropped off. Couldn't explain it. I measured phantom power at 39vdc. I think that should be sufficient but maybe not. I know the mic is solid on another Behringer UMC22 that I borrowed.
You mentioned a wish for the 3.5mm plugin power to be in the 5v to 10v range. Are there any devices which provide that much voltage? Most of the devices that I've tested are in the 3v to 5v range. My Behringer 302 mixer, provides about 4.5v, which seems to be enough for every electret mic that I've tried.
@@Chris_Grossman It's a pity that the Teyun falls down on certain aspects of its performance. There aren't many USB mini mixers that offer two XLR inputs.
Hello Sir, I want to know if i use this mixer with my studio monitor speaker by using 2 trs cable and plugging it into the main output port of audio interface, Will it improve the audio output quality as compared to directly connecting it to the PC.
You are pop pop popping non stop bro, p s and t maybe move it away a little from your direct mouth breath and spit. This is a neat instruction as I have a few $200 mini xlr head mics that would be fun to change.
Hi Chris could I bring my big analog mixer into the line inputs to go to computer, you can get rid of all the noise and breathing in on your voice over with the basic noise reduction on in obs, the expander and limiter is extremely good too.. 44.1khz is standard for my radio ads 48 is a bonus.
Good review. I worked in electronics for 40 years. It would seem like a schematic of the thing could help to make some changes to the design to fix the shortcomings. Possibly add decoupling caps to the A2D section (Try to understand where the noise is coming from), add an external power connector, tweak a cap/resistor value or two, if that can be done, to give more gain. Beef up the step up voltage circuit to provide a higher voltage for the mic. This isn't rocket science.
Once again, and excellent video with '"gettin' into the weeds" on components and functioins. This is a thoroughly enjoyable presentation for those with a tech background. Bravo !! Chris, I make a quick demonstration of what the Tenyu Q-12 sounds like with a dynamic mic (and some EQ and reverb) Here is the result. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-adqd83deR-U.html
Bravo !!! Well done. You included some resistor values, information regarding differential pair (transistors built into, probably a standard IC), phase, etc., that you don't see a lot of times in reviews. You were very thorough in this review, and those of use with technical (electronics) backgroud, got out "tech fix" with this review. All that I can say is that you did and excellent job on this review. I, too, have this Q-12 (I'm always up for trying out audio products that are cheap and cheerful. I suspect that electronic tech are more prone to appreciating clever, useful economy products, and rely much less on evaluating products based soley on brand name.) If you're curious, I'll put a link to a guitar (Squier Sonic Strat with stock ceramic magnet neck pickup) and I'll put a link to the $15 BM800 Condenser Mic, too. These are not anaysis videos, they are just very short demonstrations of these products being used. Thank you for your wonderful video. Here are the links. ru-vid.comtJ2R0GJZ3vE And here is one for the BM800 Capacitor Mic. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--CmajpPu25s.html
I just got mine recently, and here are some of the pros and cons. If you want to use it as a usb connector for your recording, it does it's job really well, but since the design is simplistic and minimalistic and its only features are gain and volume control I would suggest to pair it with a multi-channel audio mixer or a soundcard that has vocal effects on it like reverb.
Thanks for the extremely detailed review and measurements! Is there some ways to improve Q-12? Will swapping resistors to 6.8 kOhm improve 48V phantom power? Please consider to do a video of fixing/upgrading the Teyun Q-12.
Sir.. I need your help.. I bought my first elec-guitar... So, I bought Teyun Q-12.. But I cant find Driver.. and I cant use my guitar.. How did u can download Q12 driver? Plz.. Im from korea (Not north)
The Teyun Q-12 does not need a driver. You need to isolate your problem. > Try a different USB port > Try a different USB cable > Try it on a different computer
