But this isn’t *real* reverb. How do things work out in practice? P.S. If any of them shorts pin 1 to pins 2 or 3, whether due to a bad cable or a bad connector, you will indeed cook that ribbon if you apply phantom power. b) Never turn on/off a preamp when phantom power is engaged. The first thing to remember is that ribbon microphones are inherently delicate due to the way in which they are constructed. Now in theory, until the other pin has connected, there is no circuit for any current to flow through, and when it does connect it will be at the same voltage so still no current will flow. Any shock could damage the ribbon and its mounting. For this reason, it is commonly recommended that phantom power be turned off when using ribbon microphones. Patchbays are definitely a problem however. But why you’d use a junky old short-circuited cable with your nice ribbon mic is beyond us, so forgive us for sounding preachy. Mixing is a complicated “mix” of art and science. Unless a microphone is unreasonably delicate therefore, connection to a phantom-powered input should pose no problems. Read more in the Royer Labs whitepaper, or better yet, check out Jon Ulrigg’s video demonstration. A Typical Recording Console with Phantom Power Ribbon Mic and Phantom Power Problem Defined. However, we still recommend that you deactivate phantom power when Royer microphones are being connected or disconnected simply because other abnormal conditions may exist that could cause problems. But that sounds less like phantom power than like ghosts in the machine. Some ribbon microphones have internal preamplifiers and require phantom power. Or could it stretch the ribbon element and just ruin the tonality of the mic? says the typical home-studio owner. Leaving phantom power on can result in a stretched or completely blown ribbon. I want to use a non ribbon dynamic mic and a condensator mic on my AudioBox 44VSL. It is best known as a convenient power source for condenser microphones, though many active direct boxes also use it. So for a moment, one pin has +48 volts connected, the other doesn’t. I engage the phantom power for my condensor mics. But ribbon microphones are different. 2 I have a Nagra IS. If I use a separate mic pre for a ribbon mic (sans phantom power), that is then sent to the E8 line level, does the phantom power of the E8 reach the ribbon mic? Your compressor adds noise to your recording. You may have to register before you can post: click the register link above to proceed. One of the beauties of phantom power is that microphones that need it use it; microphone that don’t need it ignore it. Why does it do that? How did you do it? To start viewing messages, select the forum that you want to visit from the selection below. I don’t have any personal experience of what damage this could cause, but my alarm bells would certainly be ringing. In the manual it is said that a ribbon mic woul be damaged, nothing about the non ribbon. However, if there happens to be an imbalance in the amount phantom power voltage being applied to each pin, the power can damage or destroy a dynamic mic. | Privacy Policy | Terms of Use, How Google uses data when you use our partners’ sites or apps, Ready to take your recording to the next level? Marik doesn’t recommend that vintage ribbon mic owners open up the mic housings to check for the wiring on the transformer. a) Never store a ribbon mic horizontally (even Beyers M160?) But that’s the theory. For this reason, it is commonly recommended that phantom power be turned off when using ribbon microphones. The scenario that is least likely to damage your ribbon mic is where phantom power is switched. I'm building a ribbon mic, it's coming out really well the only problem I came across is the transformer. Mic Database | Mic Reviews | Microphone Sale, Wednesday, April 2nd, 2008 | by matthew mcglynn. In phantom power, +48 DC is connected to both ends of the secondary coil. Ribbon technology can be traced back to the beginning of the previous century. Wes Dooley at AEA is another longtime proponent of ribbon mics, and a real expert in their design. Why is this so? For this reason, it is commonly recommended that phantom power be turned off when using ribbon microphones. I can't understand what one to buy in my case (and they are god damn expensive), so I had the idea, ditch the transformer, and use the phantom power from my Focusrite Scarlett 2i4, although to me it seems a god idea I thought to ask the internet first. If you have a tip-ring-sleeve microphone patchbay (which some would argue against, but they can be very practical) with phantom power applied, then as you plug in the patch cable the microphone is exposed momentarily to the full 48 volts across pins 2 and 3 which, at the moment of connection, will transmit through the transformer to the ribbon. For those, phantom power is a NO NO. Or even just one switch for all the channels. Do you intend to soundproof your... (adsbygoogle = window.adsbygoogle || []).push({}); 1 I have a mixer that supplies phantom power to all channels (Soundcraft E8). I'm building a ribbon mic, it's coming out really well the only problem I came across is the transformer. http://www.royerlabs.com/phantompower.html, Quote “The ribbon elements in some vintage ribbon microphones can be harmed or even destroyed by the presence of phantom power. Wouldn’t... FREE EBOOK DOWNLOAD ► Come on the FREE COURSE TOUR You need to ventilate your studio. Thanks for your advice, as always. This is particularly true with ribbon mics (a type of dynamic mic), where an imbalance of power flow can destroy the ribbon in the mic. So peel the tape off that +48 button and stop sweating the phantom-power myth. In some cases, the microphone may still operate, but at a greatly diminished capacity.”, “Royer ribbon microphones are not usually affected by the presence of phantom power. It’s a digital imitation. Myths, unlike the egos of most guitar players, require at least occasional affirmation to grow. One final point – if you have a vintage ribbon microphone, then it might have a centre-tapped transformer and current from the phantom power supply will actually flow through the secondary coil. Adding a delay before the reverb kicks in can create an interesting sound texture and make heavily-reverbed vocals more intelligible. Get the Audio Masterclass Newsletter, subscriber-only info and special offers too... FREE EBOOK - Equipping Your Home Recording Studio. What could conceivably happen is that one pin makes contact a fraction of a second before the other. The problem with patch bays is that they use TRS (tip-ring-sleeve) connector cables, which can (during insertion) momentarily apply phantom power, if present in the patchbay circuit, to the parts of the TRS connector where they should not. They can be severely damaged by phantom power. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2000 - 2020 Imaginative Resources Ltd. and licensors.
