Is 48 volt phantom power safe?

CAUTION/DISCLAIMER: In answering this question, I make a basic assessment about the safety of Phantom Power. This is a basic assessment, and I take no responsibility, and this website won't, either, for actions taken following this assessment. DO NOT SHOCK YOURSELF DELIBERATLY UNDER ANY CIRCUMSTANCES. ELECTRIC SHOCK CAN KILL. If you wish to attempt something which could potentially result in shock using phantom power, TAKE ADVICE FROM GOVERNMENT INSTITUTIONS THERE FOR THIS PURPOSE (risk assessment), such as the HSE in Britain (www.hse.gov.UK). Phantom Power is a 48 volt DC electric supply provided down the two signal cores of an audio balanced cable, usually 1-2mA, but recently up to 10. It is used mainly by the audio industry to power microphones from a sound desk using the signal cable, eliminating the need for a separate supply. There are two possible definitions of "safe" in the context of this question. The first is risk of electric shock. Arizona State University teaches that 5mA or less is 'safe'. According to this definition, Phantom Power is safe. This is also borne out by many professionals using this technology on a daily basis, and who sometimes get shocked. It is very doubtful it would affect the heart, and probably wouldn't cause burns, either. However, as I have explained above, take normal electrical precautions (disconnect before working on/don't touch two wires) when using such equipment. Remember that Phantom Power uses earth as it's neutral, and thus it is easier to be shocked than most equipment. The other side to this is whether it is safe to use Phantom Power on equipment not designed to receive it. This issue arises when Phantom Power has to be applied to all channels on an audio mixing console. This is known as Global Phantom Power. In most cases, microphones which don't use Phantom Power aren't affected: Global Phantom Power is a feature on many desks, and something microphone manufacturers take into account. Sometimes, the power supplied by the desk may not be adequate for modern microphones (you may end up with a 1-2mA supply for a 10mA microphone). However, one note of caution. If you have equipment which can be powered by Phantom Power or by battery, it is advisable to remove the battery when connecting to Phantom Power.


Why does a static condenser differ from synchronous condenser?

Unlike a static condenser (capacitor bank), the value of reactive power from a synchronous condenser can be continuously adjusted. A synchronous condenser also has other advantages over static condensers such as: - not being affecting by harmonics (some harmonics can even be absorbed by a synch condenser) - producing no switching transients


Full form of DC power supply?

DC Power is Direct Current Power Supply.


Is a 24VDC power supply short-circuit protected?

That would depend on the power supply.

What type of microphone uses phantom power?

A condenser microphone uses phantom power.


Do usb condenser microphones need phantom power?

Unless they have a battery built in, if it's a pro condenser microphone with an XLR cable and it doesn't have a special funky power supply just for it, turn on the 48V phantom power. It won't work otherwise. Dynamic mics will ignore phantom power generally.


What is phantom power and what are its uses?

Phantom power is 48VDC power applied by a mixer or preamp or other piece of gear to power a condenser microphone or Direct Inject (DI) box attached to it. It can coexist with the microphone signal, and dynamic microphones generally will ignore it and not be hurt by it.


What is the function of condenser microphone?

The one thing you need to know when using a condenser microphone rather than a dynamic mic is that the condenser needs something called phantom power. This is a small charge of 48v that powers the microphone. Thsi charge comes generally from the mixer, which is usually either a button on or by the channell inputs, or a switch by the power switch. Also if your mixer does not have phantom power, or you are trying to hook up the mic directly to something like a a computer. you can buy an external phantom power source. Usually some sort of box.


I'm a noob to recording so if have a 9-track mixing board do I need a preamp to run a condenser microphone?

A preamp is required for all microphones, and is built in to the mixer if it accepts microphone inputs. The feature required for most condenser microphones is phantom power, a 48 volt signal that is supplied by the mixer to power the electronics inside the microphone. You must use an XLR (three pin) cable to connect the mic to the mixer to provide this power. There will be a Phantom or 48V switch on the mixer to turn this feature on and off.


What connection is there to connect a camera to a professional microphone?

Professional and semi-professional cameras are fitted with microphone inputs, often using an XLR connector. The XLR connector is the standard professional microphone interface and allows any good quality microphone to be connected and used, including radio microphones.Domestic camcorders will not use an XLR but some have a 3.5mm audio input jack that will handle a microphone level signal. If there is an audio input on your camera, it is important to read the manual to establish the type of connection it offers. Some are single channel, others are stereo while a few will only accept certain types of audio signal. If the audio input handles microphone level signals, it is usually possible to obtain or make a cable to connect a professional microphone to the camera's mic input.Phantom Power: Many professional microphones require a power supply to operate, known as "phantom power". It is usually a 48 volt power supply that comes from the camera. Domestic cameras are unlikely to have such a supply so if the chosen microphone requires a phantom power supply, a separate, in-line phantom power unit will be needed.

Can you use phantom power for a dynamic mic?

Phantom power won't hurt your dynamic mic, but it also won't help it. Turn off phantom power if you're using a dynamic mic. Only condenser microphones need phantom power.


Is the mike recording quality of Boss BR600 recording studio any better than that of Behringer C1U condenser mike?

No. The built-in microphones on the Boss BR600 will not sound as good as a Behringer C1U USB condenser microphone. You should also note that there is no way to connect the C1U microphone to the BR600, as it requires a computer with a USB port to operate. If you want to improve the sound of the BR600, you will need to connect a microphone to the 1/4" inputs jacks using a microphone that has this connector, or an XLR to 1/4" adapter cable. Note that the BR600 does not have phantom power, so powering a condenser microphone like the Behringer C1 is not possible.


What is a dynamic microphone?

It doesn't need phantom power to work. It's usually in a cardioid pattern.

How do you properly hook up your mtx condensor microphone to your laptop via usb?

Unless you already have a soundcard with phantom power, then one relatively inexpensive solution is the Tascam US-122 USB Audio/MIDI interface. That's what I use to power my condenser mic and the sound is very clean and crisp. Good luck!
