For this reason, it is commonly recommended that phantom power be turned off when using ribbon microphones. This will only transmit through the transformer momentarily. On the other hand, using ribbon microphones in combination with other microphone types is a normal working situation. Myths, unlike the egos of most guitar players, require at least occasional affirmation to grow. It is best known as a convenient power source for condenser microphones, though many active direct boxes also use it. I'm building a ribbon mic, it's coming out really well the only problem I came across is the transformer. Do you intend to soundproof your... (adsbygoogle = window.adsbygoogle || []).push({}); And just as it is sensitive to physical shock, the ribbon mic is sensitive to electrical shock too. There are exceptions to this but it’s best to regard a ribbon mic as needing special care unless reliably informed otherwise. This is because the coil of the diaphragm in a dynamic mic, and the ribbon in a ribbon mic, is connected across the primary coil of the transformer. May this damage the non ribbon dynamic mic? What?! 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. You are going to learn everything you need to know about Audio Masterclass to get your career moving. Ribbon technology can be traced back to the beginning of the previous century. I want to use a non ribbon dynamic mic and a condensator mic on my AudioBox 44VSL. How did you do it? Patchbays are definitely a problem however. It is often considered good practice not to let air push against the diaphragm as you walk from the mic cabinet to the studio floor, and certainly don’t run with it (although when do you ever see sound engineers run?). In the manual it is said that a ribbon mic woul be damaged, nothing about the non ribbon.

But that’s the theory. Can a plug-in improve your monitoring acoustics? Transformers to do not pass direct current, and in any case, both ends of the secondary coil are at the same voltage, so no current flows through the secondary coil due to phantom powering. What could conceivably happen is that one pin makes contact a fraction of a second before the other. While most engineers wisely steer away from letting phantom power come anywhere near their ribbon mics, some newer mics, such as the active Royer R-122 MKII, AEA R84A, or Cloud Microphones 44-A, utilize phantom to power their electronics. We’re assuming your cables are in good shape. But this isn’t *real* reverb. 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. It works with a very thin sheet of metal between two magnets. Or even just one switch for all the channels. If this is your first visit, be sure to check out the FAQ by clicking the link above. Since switching occurs simultaneously on pins 2 and 3 of the XLR mic input, there is no possibility for any current to flow, other than a very small amount due to any slight mismatch of the resistors through which the phantom power is fed.

Update, 2008-12-01: Ribbon mic expert Mark “Marik” Fouxman wrote in with a cautionary postscript about some vintage ribbons: There are some vintage ribbon microphones that have transformer secondary with grounded center tap. b) Never turn on/off a preamp when phantom power is engaged. 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.

So for a moment, one pin has +48 volts connected, the other doesn’t. I’m here to tell you that the idea that phantom power is a ribbon killer is mostly a myth. I don’t have any personal experience of what damage this could cause, but my alarm bells would certainly be ringing. Here’s what Royer Labs has to say about phantom power and ribbon microphones: Royer ribbon microphones are not usually affected by the presence of phantom power… Turning the phantom power on or off after the mic is connected should pose no problem whatsoever. The example that Jon puts up shows that EVENLY applied P power is fairly OK. It’s too bad that there are many times that is not the case. The companies you mention don’t want to do any more ribbon repairs than necessary. Leaving phantom power on can result in a stretched or completely blown ribbon. Clearly they are not going to be damaged by it. I have to put the phantom power ON for the condensator mic and I understand it applys to the 4 inputs. Because if your sound insulation is good, you have also blocked all the pathways to fresh air. Nonetheless, applying phantom power will not damage other microphones in the vast majority of cases. 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. In this video, Jon bares the ribbon from one of his mics and demonstrates the complete lack of disaster that follows when phantom power is applied.
