Connecting a 3.5mm (ATR-3350) microphone to a XLR / ¼ audio recorder (Tascam DR-40, DR-44, Zoom H4N)






OK, so here’s the problem:  You finally saved up enough money.  You washed 100 cars, cut 100 lawns, or whatever the case may be.  But you finally saved up enough money to buy your first audio recorder. And there are many reasons you would want to have one for video production.  But, the point is, you have one, or else you would not be reading this post. 







Furthermore, you also decided to get a nice fancy one that has a couple of XLR inputs, because, eventually you will want to buy one of those fancy XLR microphones.




But, in the meantime, before you can cut some more grass, you’ll want to connect your collection of cheaper  microphones or lavaliere microphones to this baby.  But those all have a 1/8" plug.  






 Simple right…?  Just get a one of those 1/8" to 1/4" microphone converters.  Since these recorders have a combo XLR / 1/4“ input.  Well, I just happen to have a couple of these around the house.  So I connected my mics to the adapter, then plugged the adapter into the recorder.

But to my dismay, it wasn’t working.  No signal.  The funny thing was that when I jiggled it around, and slightly unplugged the microphone from the adapter, I was able to get the sound.  This had me scouring the internet for answers.  Yes, the ENTIRE internet.  I found a couple users with this problem, but no solution.  Maybe the answer was such an elementary solution that they were embarrassed to post it.

But, that’s not me.  So go ahead and laugh, but I’m sure there will be at least one person out there that will say ‘hey man, I made the same mistake, thanks.  So for you sir (or Maam), here’s the solution:










The thing I didn’t know was that these adapters are not all the same.  When I started to look online, I noticed that some were stereo to stereo, some were mono to stereo, some stereo to mono, and some were mono to mono. 

The inputs on these recorder are mono.  So basically, depending on the mic you are connecting, you will want either mono to mono, or stereo to mono.  I would recommend buying two of each kind.  You may eventually need one or the other. In case you have any of these mics, these are what I needed for them:



stereo to mono  -  ATR 3350 Lavalier
stereo to mono  -  Audio-Technica PRO24CM
stereo to mono  -  Aputure V-Mic D1
mono to mono  -  Neewer 14.37 inch Shotgun


$4.43/2 - mono to mono
$3.44/1 – stereo to mono

Free Sounds


Adding quality sound to your videos or podcasts can be pricey in the professional world. Take a look at this site: http://www.sounddogs.com/sound-effects.asp.   Unless you happen to be a sound engineer or know a musician with a handful of quality music tracks to lend you, you'll need to find yourself some royalty free sounds.  Here are some of my favorite sites for free sounds.  Please note that while you can download music tracks for free, you may still be required to credit the original artist if you plan to publish any works using the tracks.  Please read all disclaimers when downloading other people's work.


Sound effects and royalty free music.  Just pick a category, preview, then download what you want.  Registration required.  Musical selection not quite as big as the sound effects.


Sound effects only.  This site lets you key word search for your sounds, or browse tags, to categorically search for the right sound.  They also have a system that allows you to rate the sounds. 


A nice, clean looking site with a lot of free sounds.  Keyword search, and easy download.  No registration is required here to download sound files.




This site has royalty free tracks created by Kevin MacLeod.  Keyword search is available, but you   There are plenty of quality recordings to use.  Don’t forget to attribute the artist.  There is also a keyword search, but you will probably want to click the genre or mood that matches the type of music you are looking for.

Microphones








Microphones come in many varieties, shapes and sizes.  Some mics can do you well in one circumstance, but be wrong for another use.  Here is a basic run down on the different types of microphones available, and their best uses.





Condenser Microphones
These mics have electrical circuitry that amplifies the signal being produced, and as a result are very sensitive.  They also require a power source to be operable.



Dynamic Microphones
Dynamic microphones are less sensitive than condenser mics, and generally can take more punishment due to simple electromagnetic construction. Dynamic mics are typically used to record live instruments and vocals, but also work for studio vocals as well. To further complicate things, microphones can have different pick up patterns, and consequently be used for different applications.





Cardioid 
Cardioid microphones pick up sound in the front, about 120 degrees. They reject sound from the rear and sides.  The pickup pattern resembles a heart, hence the term cardioid.







Hypercardioid
These microphones also pickup sound in the direction they are facing, but have an elongated, 100 degree pick-up pattern. There side rejection is superior to cardioid microphones but also pick-up a little sound from the rear.








Bi-Directional
The pickup pattern on these mics resemble a figure eight, picking up sound from the front and back, and rejecting sound from the sides. These mics are popular selections for broadcast microphones and headsets.







Omnidirectional
These cover all directions and picks up all sound in a 360 degree radius. They are typically used for natural, ambient recordings as well as lavaliere microphones – since head movement will not effect the volume of the recording.  These are also often used for headset microphones. 




Low Cost Recommendations
1/8” – Connects to a camera or recorder
XLR – Connects to a mixer
USB – Connects to a computer



Shotgun - Condensers
A shotgun mic is one of the most common mics used in professional television and film production.  Their hypercardioid pickup pattern make them ideal to focus on dialog.  They are typically mounted on a boom pole and placed on top pointing down on the action.







Dynamic
When recording a podcast or radio show, you probably want to record in a somewhat soundproof room that will cancel out background noise and echo.  Dynamic microphones are preferable because they do not pick up a lot of ambient noises due to their weaker signal.    





Cardioid - Condensers
Condensers are very sensitive so make sure your studio is properly soundproofed to ensure a quality recording.
