Frequency Transmitter Techniques

!±8± Frequency Transmitter Techniques

They are referred to as radio or wireless mics but are actually a case in which the original audio cable was replaced by a frequency transmitter technique. Radio mics are commonly used in transmitting audio by radio waves such as AM, FM, VHF, UHF or any other digital format.

The better ones operate from numerous frequencies that they use for transmission. That is why they hardly ever experience any interference by other electrical transmitters that are within the same frequency. They can enable the use of many microphones at the same time.

The very first type of radio microphones started as compander microphone development way back in 1976 and was used by Nady Systems. They were given recognition in 1996 and given an Emmy Award due to their technical input in the technological sphere.

These mics have many advantages because it enables the user to hold to some health and safety standards. They can now work without exposing themselves to too much risk due to what used to be the trailing cables of the microphones.

Then there is the advantage of easy movement because the wearer does not have to use any cables trailing the microphone. It used to be the case that the cables actually had some strain or stress because of the way they were tagged and pulled all the time. This used to cause them easy damage.

It might look like the advantages of the wireless mics far outweigh the disadvantages but wait a minute. What about the fact that the two way batteries are now not very long-lasting and they use much power?

Another disadvantage is the fact that the signals are normally hampered by the distance. They will require very strong and expensive batteries if you want to receive strong signals at a further distance. Interference is also caused easily by some electrical appliances that are within the same range.

It requires that one limits the number of radio microphones that can be used simultaneously in one given range.

A Simple In Home Recording Set Up to Create High Quality Audio Products For Your Business

!±8± A Simple In Home Recording Set Up to Create High Quality Audio Products For Your Business

When I first heard about podcasting almost three years ago, I knew right away I wanted to do it. Once I learned how, I decided to have a small scale in-home recording studio to record my podcasts. With the guidance of my webmaster who is my tech guru, I was able to quite inexpensively put together all that I needed to record. She was able to shop around and get my reasonably priced equipment and all the equipment was user friendly. 

Now if you find yourself thinking "Well, she could do that, she's probably into technology", you'd be very wrong. I am a Baby Boomer woman and when I was in college, computers took up the size of a large climate-controlled room and you had to do keypunch cards to program the computer. Personal computers came along and the most techie thing I could do, until I learned about podcasting, was create Word documents and open email. But I learned and if I could learn, so can you. 

So what's required in this simple in-home recording set-up? Actually, not a whole lot is required. I have 7 pieces of equipment. I have my laptop (of course you can use your PC), a studio quality microphone, a desk microphone stand, a pop screen, a converter, a microphone mixer (to boost the sound) and a Y adapter cable (to connect mixer to converter). That's it.  

I use an Audio-Technica Pro Series Vocal Microphone (PRO 31 QTR). A wide diaphragm condenser microphone is recommended for voice-overs but I find that my 2.09-inch (53.1mm) head diameter gives me great sound for my podcasts and CD recordings. This microphone comes with the cable and a stand clamp. 

The microphone stand I use is a desk model and comes from On-Stage Stands. I use a metal pop-screen from NADY but there are many to choose from that can clamp on to your microphone stand. Pop-screens cut down on the explosive or wind sounds we make when we say certain letters.  

My microphone mixer is from Radio Shack and is a Stereo 4-channel mixer. It uses a 9-volt battery. 

My converter is from Behringer (FCA202). It is compact and really high quality for the money. It comes complete with FireWire audio interface. 

All my equipment has lasted beautifully for over two years so I have yet to replace any of it; the model numbers probably have changed. 

The microphone receives the sound which is sent to the mixer which sends it to the converter via a Y adapter cable. The converter is where the magic happens- taking your voice which is in an analog signal and converting it to a digital signal which it sends via FireWire to the laptop and the recording software.

Now comes the software part. You will need a software program for recording and editing sound. I have always used Audacity; it is open source program and therefore is free. (There may be a licensing fee for Audacity in some countries.) The software can be downloaded from the Audacity site. There are other programs available that are fee-based such as SONY Sound Forge.  

You will also need a software program to export the audio file you create in your recording program into MP3 or WAV. The LAME recorder does this for you; it is also open source and can be downloaded for free. (There may be a licensing fee for LAME in some countries.) Just Google in LAME encoder and it will take you to the site. Please note that it doesn't work in all recording software programs but it does work with Audacity.  

I convert both to MP3 and WAV, using the WAV files if I am going to burn a CD of my recording. 

You may be saying that this is a lot...why don't I just record over the phone and use a program like Audio Acrobat? You could but the quality of sound is nowhere near the quality of the set up I recommend. My recordings always sound like I recorded in a studio (except when I do phone interviews). 

The quality of sound is important when you offer long audios...especially if you are recording for a home study system or sending your lessons or teleclasses out via MP3 download. After a while, the hiss and scratchy sound of phone recordings wears out the ear of your listener. Why not go with the highest quality you can for your audience?

Radio Microphones - An Overview

!±8± Radio Microphones - An Overview

They are more commonly know as radio mics or wireless mics, where the original audio cable is replaced by frequency transmitting technology. Radio mics can now transmit audio through radio waves in FM, AM, UHF, VHF and various digital formats.

More advanced models will allow you to select various frequencies to transmit over, helping avoid interference with other electrical transmitters that might be using the same frequency, and also enabling the use of multiple microphones at the same time.

It is thought that the primary radio microphones derived from the original compander microphone developed in 1976 by Nady Systems, who was honoured in 1996 with an Emmy award for his technical contribution to the technology field.

Radio Microphones - Plus Points

Using radio mics is very advantageous for the user. A starting advantage is that radio mics eliminate the health and safety risk of trailing microphone cables. Secondly, and as a result of this, you give the freedom of movement to the wearer of the microphone as they are not joined via a cable. Another plus point is that you no longer stress any cables by flexing them, which can frequently result in damage.

Disadvantages of Radio Microphones

Despite having such advantages, wireless microphones also have some select disadvantages. Firstly the two way radio batteries used do not always last very long as the radio microphones are very thirsty when it comes to power consumption. Radio mics are also hampered by range, with the furthest signals normally only achieved by the larger, more expensive models. Interference from another electrical appliance is also a possibility which would lead to a disruption of the signal. Finally, to avoid being on the same frequency and clashing, you are limited to the number of radio microphones you can use.
