So there is no need for a separate plug or cable to provide power to the microphone. With the MixPre, MP-2, and USBPre - all two channel products - a maximum of 960 mW (nearly a watt) can be drawn from the batteries. Remember to connect the mic BEFORE turning the phantom power on! i have a question: can i damage a dynamic mic when i put it in a 48V bus? This sounds really technical, but really all that means is they convert one form of energy (mechanical) into another form of energy (electrical). This website uses cookies to improve your experience while you navigate through the website. Although most condenser microphones tend to be expensive compared to other microphones, their high prices are justified by the fantastic sound they deliver. Copyright © 2017 Magroove - All Rights Reserved. You need phantom power for the electronic circuit to work. Phantom / self-powered (internal battery) microphones which operate on phantom voltages from 9 - 48 volts. For you to charge this plate, you must supply power to the microphone. link to Are you writing an album? Unlike dynamic microphones, condenser mics have a diaphragm suspended at the front of the plate, electrically charged. Microphones which operate on voltages from 9 - 48 volts. Make sure you never plug ANY microphone with the phantom power on, even if it isn’t a condenser microphone! For those using mixers or audio interfaces that do not have enclosed phantom power, it would help if you do these two things: Why Do Condenser Microphones Require Phantom Power? "Phantom powering" is a method of providing power to microphones by applying a voltage to the same wires that carry the audio signals. Phantom powering condenser microphones is the single largest power drain on the product, and battery life is directly affected by the microphone type and voltage powered. Do you and your favorite condenser mic the favor and hit that 48v switch. When buying any XLR microphone you will need to buy and audio interface or mixer to connect it to you laptop or computer to record and with virtually all modern interfaces, even cheap ones, phantom power comes as standard. There are two main types of microphone you are likely to come across in your musical journey (there are of course other types but they are less common). This voltage is transferred through the microphone cable from a mixer with the phantom power feature. The definition of phantom power is an equal voltage applied to pin-2 and pin-3 with respect to pin-1. These cookies do not store any personal information. A condenser microphone such as the Rode nt1a, nt1 or Audio Technica AT2020 is a more intricate piece of kit, and that is usually reflected in a higher average price. Because of the way that they are designed, condenser mics require a power source to function, unlike passive devices like dynamic mics. Because Sound Devices products are portable and run from batteries, power used to operate microphones reduces battery runtime. Since the voltage appears on both pins 2 & 3 on a dynamic mic, there is no voltage potential created meaning that both sides of the mic coil see the same voltage. Condenser microphones tend to be more pricey than their regular mic counterparts for a good reason – they have amazing quality. So if you are looking to use your condenser microphone in more of a live setting and want to connect it to a PA system or amp, it will need to go through a mixer which has phantom power abilities. Because of their intricate designs, condenser microphones are much more delicate and prone to damage. So the best way to understand why phantom power is required in all condenser microphones such as the Rode nt1a is to understand how they function. In general, phantom voltages are used to power electronics within condenser microphones. In reality though, you are much better using a dynamic microphone when not in the studio. How Does Phantom Power Work? As a result…the method to deliver the voltage is invisible…a “phantom.” (Early condenser mics used additional wires to deliver the voltage). This is like driving a Lambo in a school zone all day vs driving it in a race track! This voltage is transferred through the microphone cable from a mixer with the phantom power feature. I started Microphone Authority to share information on the best sound setups, practices, and products. New specifications from the AES outline five specifications for phantom voltages and current levels - P12L, P12, P24, P48, and P48H. In general, phantom voltages are used to power electronics within condenser microphones. Due to the fast transient response and high sensibility to air flow and sibilance, it may ring a bell of what is a pop filter for. Its construction is very delicate. This is a question I get asked a lot, people will often email me asking if a specific model of condenser microphone, for example the Rode nt1a, the Rode nt1 or the Audio Technica AT2020 need phantom power to work. Most condenser microphones are very sensitive to sound and have the capability to pick up many surrounding sounds. Electric current is supplied to the microphone by the phantom power through the cable and XLR socket. Keep in mind that the volume of those three sounds is vey different, even if they are all played with the highest intensity possible. Necessary cookies are absolutely essential for the website to function properly. Flat frequencies with more detail in high end. Two words … phantom power. Musician's HQ is a participant in the Amazon Services LLC Associates Program. Patterns: Omnidirectional, open and closed cardioid, hypercardioid and figure 8. As there is a voltage on pins 2 & 3 an extremely small and very cheap cable tester can be made, which will tell you if the cable is good, and also if the Phantom Power itself is good. Condenser microphones such as Shure's KSM range all have active circuitry and require phantom power. Knowing what microphones require it, tells you what channels will need it. Created in 1960, it is very common in recording studios. That summary is very brief and if you want a more detailed explanation of exactly how condenser microphones work, why phantom power is needed and finally how you get phantom power then please read on. These are dynamic microphones and condenser microphones. Since power draw is in direct proportion to voltage level, power draw is significantly increased when running at higher phantom voltages. It is why they sound really good. If you are unsure the manual should tell you whether or not it has it. Sound Devices products provide up to 10 mA of phantom power per microphone input at 48 volts. These days, the vast majority of them require what is called phantom power to work, … Your email address will not be published. Rob has come to terms with the fact he will probably never be a famous rock star....but that hasn't stopped him from writing and recording music in his home studio. With such advanced features, these mics are used to record sound effects and instruments like piano guitar, percussion, and other percussion instruments. Condenser microphones require power for various parts of their operation, including impedance converters, preamplifier circuitry and, in some cases, to polarized microphone capsules. Phantom is usually a DC voltage ranging from 12 to 48 volts. Condenser microphones require power for various parts of their operation, including impedance converters, preamplifier circuitry and, in some cases, to polarized microphone capsules. Its function is to “translate” the sound pressure transmitted by air vibration into electric current variation. Because phantom voltage is exactly the same on pin-2 and pin-3 with respect to pin-1, phantom power has no effect on balanced, dynamic microphones. But why are they amazing? Their backplate is polarized by design. The 48V Phantom Power is delivered to both pins 2 & 3 using pin 1 as the ground. The 48V is presented to both pins 2 & 3 and pin 1 is used for ground. A small amount of power is applied to these pieces of metal causing a static charge between them. If you don’t turn on your 48v Phantom power switch, it will record all sound at very quiet levels. Typically no.

My additional question, on the same line as Rik Beck’s though, is this– what happens to an input, either instrument or non-condenser mic, that has phantom power applied to it? Condenser microphones almost always need phantom power.This is a 48V voltage that is usually supplied to the microphone from the mixing board or mic preamp by the XLR cable. These microphones are primarily used for recording vocals, sound effects, and instruments including guitar, piano, trumpet and percussion type instruments.
