The history of 48V is weird. It comes from Norway radio relay stations that had to be able to be run from backup battery. They used 4 x 12V lead-acid batteries (or 2 x 24v) because of availability. There had to be equipment designed to use that power and that solution started to spread elsewhere. So when it came time to actually implement "phantom" power, 48V was logical choice as there were already gear that used it. If we had to design it today, we would never use 48V as that is stupidly high. We would probable choose 12V or 9V (but not 5V, that is problematic when it comes to circuit design, it is doable but i would not like it, also voltage loss over long wires would be a huge problem.. when things are >7V it is sooo much easier to do everything.. ).

[@seiph80]

Thanks for sharing, very interesting background.

[@SaintCrownMusic]

That's really interesting, but it makes me curious as to why we still use 48v instead of a smaller voltage. 🤔

[@squidcaps4308]

@@SaintCrownMusic Too late to change, everything is in 48V. We would have to change everything and start to use a butt load of converters. The new voltage also can't be used with XLR, it would have to be a new connector or hilarity will ensue every single day.. In reality, it only poses a slight problem for circuit designers. Current limiting has to be applied to make it safe, while keeping common mode noise low. It is not really that bad, adds another step... that not all manufacturers will do which can lead to damaged equipment but it is kind of rare anymore.

[@aditijones.mp3]

Hey Jack James. Help me buddy please. I bought a wright professional studio microphone and i don't know if it's condenser or not (not written on box but according to my memory from the missplaced manual i think it ) and the box clearly mentions "power requirement: 48V phantom". I bought this mic an year ago and still hasn't been able to set it up!!! I've changed voice splitter and XLR cable . Still won't work. It takes in the headphone but the audio just doesn't goes in. I'm very very worried. Do I need to buy a phantom power? What should I do ?

[@demerit5]

This is one of the best recording videos I've ever watched. Thank you for the upload

[@dennismiller9681]

A dynamic mic is basically a little electric generator (motion between a coil and a magnetic field produces electricity). Since no power is needed, many dynamic mics come with a 1/4 inch jack and a cable with only 2 wires for the audio signal. An optional third wire can be added for a cable ground to help fight hum, a good idea if the mic cable goes more than a few feet. On the other hand a condenser mic is basically a capacitor, a device that has two separated surfaces that can hold a charge. It takes a voltage to put a charge on the plates and this is where the phantom power is required. Rather than add more wires to the XLR cable, the power is "magically" added to the same wires as the audio signal, which I suppose is why it's called "phantom" because flip the switch and it's there, yet it doesn't interfere with the audio signal. At the preamp the circuit blocks the 48V and only looks at the audio signal. You could say that the preamp has a high pass filter up front that blocks low frequencies (48VDC has 0 frequency) and passes higher frequencies, namely the audio band of frequencies.

[@leonardotoschi585]

I have a shure sm94 which is a long range microphone and it needs phantom power because it is a condenser microphone, the other "brother" SM57 does now want it but for its shape, it is also good for long distances, for example, I use them in a theater when we have some shows, of course we cannot provide a microphone for each actor (like 5-6 in the scene) so we use them, of course the sm94 is a beast in long range compared to sm57 but they also do pretty well

[@danielarcadio]

Thanks for the video! I have a question: if I have dynamic microphones and active DI boxes connected to the same mixer, does the phantom power to feed the DI boxes damage the microphones?

[@BeanDar]

Thank you for making this short and to the point without wasting our time with plugs and ads haha

[@Videditor1067]

I am told that "Phantom" comes from no voltage coming down pins 2 & 3 when It's on. Even though there is power to each pin when connected to pin 1. Thus 1&2=48v, 1&3=48v, but it disappears when 2&3 are connected, which are you audio carrying pairs.

[@dennismiller9681]

Voltage is always measured between 2 points. You need to be thoughtful in how you measure voltage to understand what is going on. Often the best way is to measure from a point to ground. In the case of an XLR cable, pin 1 is ground. When phantom power is turned on there most certainly IS a DC voltage coming down pins 2 & 3 along with the audio signal. If you measure the voltage from pin 2 (signal) to pin 1 (ground) you will see that the audio signal is present along with the phantom DC voltage, and the same is true measuring from pin 3 to pin 1. Now if you can put both measurements on a scope you will see that the signal on pin 2 is exactly the opposite of that on pin 3. That is, if the voltage on pin 2 is going up, then the voltage on pin 3 is going down exactly the same amount, sort of like mirror images of each other. If you look on a scope you will also see that pins 2 and 3 have the phantom voltage present. So what's going on? Here's the trick -- the preamp is designed to only amplify the difference between pin 2 and pin 3. Since the phantom voltage is the same for both pins, it creates no difference for the preamp to amplify and thus is ignored by the audio amplifying circuit. But remember that the audio signal on pins 2 and 3 are mirror images of each other. Since they are different and the difference is the audio signal, then it gets amplified. Got that? The audio signal gets amplified and the phantom power does not. So why in the world did they design it like this? It's quite clever actually. If your cable picks up noise, that noise will most likely be identical voltage wiggles on both pins 2 and 3. This noise will not be amplified since it appears as identical voltages on pins 2 and 3 and is ignored by the amplifier circuit since it only amplify differences. Very clever way to cancel out some noise. This method of connecting a microphone is called "balanced" where the audio signals on pins 2 and 3 have identical but mirrored images, and is great for minimizing noise (you can never eliminate noise completely). But also be aware that a mic can be connected with an XLR cable and send out an "unbalanced" signal, such as a dynamic mic where you want phantom power turned OFF. The unbalanced connection does not minimize noise much at all compared to a balanced connection.

[@bashful228]

@@dennismiller9681 ah I thought one wire was signal and the other was a neutral reference line (no audio) to be subtracted from the signal line 9i.e. subtract noise). but mirrored makes sense, i forgot that I (learned audio decades ago!), if you subtract the negative or mirror signal from the positive you end up with 2x the positive, or double the signal strength.

[@dennismiller9681]

@@bashful228 ...yep, or you could think of it that each pin carries half the signal and the difference is the whole. Either way...

I gave up on finding band members like 4-5 years ago so I…. Got garage band, bought a cheap mic from Amazon. Bought a cheap e drum kit and learned basics, just upgraded to alesis mesh kit this past December and used garage band on my iPad. Made my first recording which is on my channel. It’s raw black metal so thankfully it doesn’t have to be “perfect” but def am trying to hone my recording craft. My dad got me a condenser mic which I used to mic my bass guitar and guitar. I thought I used it for vocals, but being new I think I forgot to turn on the phantom on the mic and my vocals just picked up through the iPad mic 😆🤣 but came out ok (ya know for being raw black metal) I’m getting a tascam dp 24 so I got a whole new world to explore soon

[@ronjames-music]

I've never used the AC adapter that came with my Behringer UMC404-HD, but the phantom power still works. I keep the interface connected to my computer at all times and at least one light stays on all the time, even when my computer is off. The second light goes on as expected when I turn on the phantom power switch. My question is this: Should I be using the AC adapter that came with this interface? If it is not needed, why was it included with the unit?

[@KohuGaly]

I recommend you read the user manual. It is probably explained there. My educated guess: The device is fully powered through the USB port, when used as an audio interface. The AC adapter is included if you wish to use the device merely as a standalone 4-channel pre-amp/mixer, without having to connect it to a computer. At least that was the case for a similar older interface I've owned.

What I know is that the phantom power basically just upgrades your mic quality and volume, while the audio interface is like a channel to connect to other devices; basically the phantom power is like an extender for the audio/sound interface. Hope this helps!

[@footnotedrummer]

I have a somewhat related question with regard to phantom power. Can you damage a tube condenser microphone if the phantom power was accidentally turned on? Most home interfaces these days have phantom power applied to banks of inputs rather than individually. I've been in a situation where I've had my tube mic plugged into channel 1 and a non-tube large diaphragm in one of the other 4 channels. Recorded a full session this way, then realized that phantom was hot on channel 1. Everything seemed fine, and I'm reading that the power supply runs blocker for the voltage backfeed, so your mic should be fine. However... did I somehow damage my power supply with this little mishap?

[@twohundredhorses]

Thanks Graham for this video tutorial. It was super helpful and here's why. As a drummer, I have always heard my musician pals on stage talking about Phantom Power but was completely baffled. The fact is, I didn't care. However, now that I'm doing a bit of drum set recording at home, a buddy lent me his Shure PG81 overhead and mentioned it needed Phantom Power. Yikes!! What do I do now and what does this even mean? Your video gave me the answers.

[@berkeyfamily9828]

I take it that a condenser mic is going to have much more sensitivity feedback in a situation where the speakers are located close to where the mic is? It seems that if the condenser mic is typically found in a studio then that is because the output of the microphone pickup is isolated from people wearing headphones. So my question is whether a condenser mic would not work well in a chapel at church for a choir, where the choir's sound is amplified by the chapel's sound system consisting of large speakers fixed inside the wall behind the choir? Is a standard coil-type microphone the best solution in such a scenario or is there other types of mics to look into for that? The phantom power must travel down one the the four nodes in the xlr cable?

What Phantom Power do you recommend if u want to use a Shure Sm-7b?

[@randomdude8897]

All Phantom Power is the same. As long as the audio interface you are plugging the condenser mic(via XLR cable) has a physical button to toggle on 48v you should be fine. In all fairness you are asking for a Shure Sm-7b which is $400 and thats with no Audio interface included. So you are looking at $400+ for equipment... I do not know if you will simply be streaming games and want to clear up your vocals or if you are going to use it for actual recording of vocals and make tracks, but if it's just for streaming games and you want to capture your voice in a crisp and clear manner you should get a Audio Technica AT2035 and a Focusrite Scarlett Solo(if you are only going to have lets say 2 studio monitors plugged in to the audio interface and your microphone and that will be about $400($150 for mic on amazon at the moment and about $200 ish if not less for the Audio interface) . If you want more inputs and outs you may have to look for their other Scarlett models. Sorry for the lengthy comment.
