Thanks for your great and crystal clear description. You asked how do they produce 48 V Phantom power from a 9 V battery? Here is a brief explanation : The 9 Volts is chopped at high frequency (over the audio spectrum to avoid introducing noise) in order to get alternating current that is passed through a step up transformer or a diode/capacitors network. Then, this higher voltage is rectified back to get CD voltage. A lot of USB audio interfaces use the same techniques to produce 48V from the 5V USB supply.
I hooked mine up to test the line output on an amp and played music through the amp via bluetooth from my phone. - I used the mono settings with one XLR input, line out to my camera input. The line setting wouldn't even give me a signal. The mic input gave me plenty of signal, but the recorded audio was awful. There was no bass. It sounded like an old RCA 78rpm without the scratches. I tested both XLR and 3.5mm inputs but the results were the same. However, I plugged in a shotgun mic to the XLR input and the quality was as good as the camera. I also tested the amp output directly to my camera mic input and the sound recorded was fine. Any idea why the line-in to the PAX1 outputs from the amp were so bad?
Would recording through this Srpax1 directly onto the camera sound as good as recording onto a zoom 4hn and then syncing in post? I wonder if the quality is better in the latter enough to warrent that extra step...thank you very much for your help!
Because in both scinarios you have the audio passing through multiple devices, I would say it won't matter a whole lot. Generally though I would say to stick with the Zoom recorder as the quality and bitrate are most likely higher than your camera. Thanks for watching and I hope this helped!
Great video but like so many others, yours has a substantial music bed throughout, making it kind of hard to ascertain the quality and the noise levels.
@@hardwiredreview I don't agree. A synthesizer keyboard has a Line level output and this mixer can be set accordantly. So that means you can record such a source like any other devices that output Line level signal. But, a keyboard has often a very wide dynamic range, so be very careful about the level. You can easily distort the signal. So play with your keyboard volume control while you play the loudest expected notes. Use your headphones and monitor carefully if any distortion occurs because there is nothing you can do to get rid of it afterward. If you got a compressor, it's a good idea to use it.
48 volts, but low current. It's a step up, it works the same way you can have a stun gun with 50,000v but still just needs a 9v battery, because there's fuck all current draw.
You have a lot to learn about audio, just using XLR doesn't automatically give you better audio quality, the reason film makers use XLR is because high quality equipment uses XLR that's all. This little box isuseless because you still have to go out of it into the camera's poor quality mic input and through it's low quality circuitry. The two things that have the most impact on sound quality are good quality preamps and good quality analogue to digital converters. But seeing as the circuitry in this unit is analogue digital converters isn't something to worry about. The problem is, you still have to go into the camera through it's poor quality mic input and preamps.
Thanks for watching everyone! ✌️

Wow, that's really interesting! Thanks for answering my question and for checking out the video!
Brilliant review - I will buy one of these units now based on this informative overview! Many thanks
03:46 A boost converter can give you a higher voltage in exchange for lower amperage. A buck converter does the opposite.

This is a great little product. Great video...congrats, Nate 👏🏻
Thank you Roger!
Your way of explanation is awesome. Very steady and clear word by word. Thanks dear. 😍😀👏👍🌷😘
No problem!
Does this eliminate the need for a cloud lifter?

@@hardwiredreview than you. One more question, do you think this will work with a shure sm7b?
@@bostonrolfwithjoelgheiler3348 it provides phantom power which I believe the SM7B needs so I would say that it most likely works.
You answered my question! A great, clear, and helpful explanation. Thanks.
Your welcome! Glad I could help.
Agreed here!
if the saraminic plugs into my camera -where does my microphone plug into -there is no second plug in on camera?
Great video! I have been looking into making my audio better. This was very informal and interesting! Thanks!
Thanks!
which microphone do you use?
If I have one mic and plug it in L or R channel will I have the jack output on both channels?
Great video but like so many others, yours has a substantial music bed throughout, making it kind of hard to ascertain the quality and the noise levels.
Can it be used to record a synthesiser keyboard through L/Mono and R line outs instead of microphones?
I don't beleive so.

Great video … thanks for sharing … 🙏🇬🇧🇬🇧🇬🇧
Video actually starts at 2:00
nice video, gotta check this out

Best review ever
I see too much of your face and too little of the product images.
