Why Are They Called Lavalier Microphones? The Legendary Electro-Voice 647A
Вставка
- Опубліковано 3 тра 2024
- In this video, I delve into the rich history of lavalier microphones, focusing on the Electro-Voice 647A, one of the earliest practical models dating back to the 1950s. I explore the origins of lavalier microphones, explaining why they are called "lavalier," and discuss their various uses.
In addition to lavalier use, the electro-voice 647, 649 or RE-85 microphones work well when used as harmonica mics, or as small clip on mics for wind instruments/horns for live performance.
Additionally, I provide recommendations for a modern, cost-effective microphones that can significantly enhance the audio quality of your content production.

This really is an interesting bit of audio history, and Electro Voice has certainly been a storied player in this marketplace. Across the board I have been very fond of their equipment. Being of a certain age I can still remember the weather presenters at our local TV station wearing those lavalier mics with the cords around their neck. Thanks Barry for the history and background on the lavalier. Just finding a NOS was interesting all by itself!
Really enjoyed this video on audio history!
Glad you enjoyed it!
Excellent video.
Thank you!
Wow I was able to hear the difference in the sound of the EV mic. Sounded crisper to me Barry. I have many mics being I have been a hamradio op. for 41 years now. I wear hearing aids also.
It definitely has a punchy sound character. I don't think it's super natural, but it does cut through. Not too bad, considering its age.
When you switched over to the vintage mic at the end of the video, I actually thought it sounded slightly clearer than your normal mic, slightly less bass but more midrange & treble.
Thanks! That old mic certainly has its own character, but I thought it was surprisingly good considering its age.
Would love to see a closeup of the XLR connector on that unit. Whether it's the locking type that was only introduced around that era, or not.. the construction, etc.
I guess your thumbnail kind of does!
Those early electro voice microphones did not come with any connectors on the cable. The microphone can be wired for high impedance, or low impedance according to the customer's need. Some customers would desire a low impedance XLR connector, and others may need 1/4 inch phone plug type connector. So, when you get the microphone it just came with a unterminated cable, and it was up to the customer to solder on whatever connector was needed.
The connector pictured I soldered on the cable.
Thanks Barry, a bit of audio history there.
Another great video Barry!
How do you determine if a Lavaliere microphone is a condenser microphone without looking over its specs? Is sending Phantom power and testing it the only straightforward way to test this? But would your sending phantom power to it without knowing if it's a dynamic or a condenser mic could be a sign that you may damage it?
Also, if another presenter is standing next to you wearing an omnidirectional lavaliere, would his lavaliere also pick up your sound signal? How to avoid it? Use an Omni for one presenter and a cardioid for the other? Thanks.
Thanks!
If the microphone is the size of a pea, chances are it's a condenser. Phantom power should not damage a dynamic mic on a balanced connection. I should have mentioned that most general purpose consumer clip on mics will terminate to a 1/8 inch phone plug connection intended to connect to a consumer camera or portable recorder. They will often include a little power pack on the mic cable with a watch battery, or expect the camera/recorder to provide a few volts of DC signal on the line (plug-in power) to power the condenser element. This is a typical feature on consumer cameras and pocket recorders.
The omni pattern works well allowing the presenters to turn their head without signal loss, but it's also not going to pick up very much that's more than a few feet away unless the background sounds are much louder than the presenters voice.
