but when it was time to try the SM7b, i forgot to tell him to turn off the phantom power. I use condenser mics for acoustic guitar and I have a Shure SM58 for vocals. Those using a guitar amplifier need an XLR cable that terminates in a ¼” plug. Didn't get any sound. Because of the way condenser mics work, their output is very high impedance, and therefore requires a powered circuit to reduce that impedance. SP T3 power supply + phantom power = kaloooey!? Insert witty self deprecating comment here. If I switch on phantom power when the Shure mic is in use, will it damage it? It will "ignore" it. That can bring in more noise from the preamp (the Mic itself is generally quiet). Power Requirements. Bias supplies power to a Junction Field Effect Transistor (JFET) connected to the output of an electret condenser mic element. (he's my best friend, and we've been recording together for years, thats the only reason I allowed him). Frequently Asked Questions Does a Shure SM57 need phantom power? The SM57, as mentioned before, does not capture the very low or very high frequencies as well as condensers. Ribbons don't like phantom and could be damaged by phantom. so anyway, after a few mics, he insisted that he didnt need me to come into the booth to switch them up. 3. Although it shouldn’t damage it, it’s advisable to have phantom power switched off when using this mic. It provides phantom power for condenser mics but it's either on for the full board or off, in other words, it can't be assigned to individual channels. This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-61938). A condenser element has a high output impedance (>1,000,000 ohms). While it does not need phantom power, it does need a lot of gain at the preamp when recording softer sounds. Why Do Condenser Mics Need Phantom Power? Unlike phantom power, bias does not require a balanced circuit. An XLR cable is also required. I ran the cable from the Shure microphone through the Behringer, and the cable from the phantom power supply to the Fishman Loudbox Mini. The alchemy of the masters moving molecules of air, we capture by moving particles of iron, so that the poetry of the ancients will echo into the future. The SM57 is a dynamic microphone.

Being a dynamic mic, the SM57 does not need phantom power. The JFET acts as an impedance converter that is a necessity in any microphone design that uses a condenser element. By DESSERT DWELLER in forum Analog Recording & Mixing - Tape & Gear, http://www.sounddevices.com/tech/phantom.htm, Recording with tablets & smartphones (iOS & Android). While it’s great you don’t have to worry about a dedicated pre-amp, you still need something to transmit the signal. Just bought a Shure SM57. Most modern mixers provide phantom power. Whichever you choose, all of these options will do a great job of giving your SM57 the additional is gain it requires. However, it will operate with slightly decreased headroom and sensitivity with supplies as low as 11 Vdc. Your sm57 is a dynamic, but not a ribbon. check out the. A professional, balanced, dynamic microphone will not be damaged by phantom power. Whether you’re recording in a studio or on stage, you’ll need a mic stand. Can You Use Phantom Power on … Still no sound. If this is your first visit, be sure to You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS. Dynamic microphones do not require phantom power and in general, applying phantom to a dynamic will not harm it. Therefore, sending phantom to your sm57 will not harm it. Find An Answer Browse our vast Answer database for answers to many common technical questions. Shure info says that it does not need phantom power. I have a Behringer PS400 phantom power supply. Dynamic microphones do not require phantom power and in general, applying phantom to a dynamic will not harm it, unless that dynamic is a ribbon microphone. Plugged it into a Fishman Loudbox Mini. Put simply, condenser microphones have active electronics that need an external power source, while dynamic mics are passive and therefore do not need phantom power.
