Have
you ever wondered why you get that awful squeal from a microphone?
Why do some sound systems sound great for speech but not for
music? The article links below are wonderful sources for finding
out.

ABC's
of AKG: Microphone Basics & Fundamentals of Usage |
![ABC's of AKG Microphone Basics [PDF]](images/Buttons/PDF_Tips.gif) |
| |
This article
presents an overview of the basic technical characteristics of
microphones, including how they work, what their acoustical pickup
patterns are, and what their electrical characteristics are. We then
move on to a discussion of basics of usage, such as how multiple
microphones interact with one another, what their target working
distances are, and how they behave in a variety of operating
environments. Our aim is to keep our coverage as simple and as "user
friendly" as possible. |

Audio Systems for Houses of Worship |
|
| |
The scope of
this guide is limited primarily to the selection and application of
microphones for worship facility sound systems. Since microphones act as
the interface between the sound source and the sound system, it is
necessary to include some discussion of these two areas, and sound in
general, in order to understand how the microphone interacts with them.
In addition, some related devices such as wireless microphones,
automatic mixers and signal processors will be discussed. |

Audio Systems for Meeting Facilities |
|
| |
The scope of
this guide is limited to the selection and application of wired
microphones, wireless microphones, and microphone mixers for meeting
facility sound systems (Boardrooms • Courtrooms • City Council Chambers
• Legislative Chambers). Since microphones and mixers act as the
interface between the sound source (the talker) and the sound system, it
is imperative to thoroughly discuss these two subjects, as well as sound
in general. |

Interpreting
Wireless Mic Specs |
|
| |
The “spec game”
is played by every manufacturer. The allowable tolerances are not
strictly controlled and there are few standards, so you generally have
to qualify or translate a particular set of specifications before you
can make valid comparisons. It is difficult enough to decipher and
compare specifications on conventional audio equipment, but it gets to
be very nebulous with wireless microphone systems. |

Micing the Drum Set |
|
| |
In this White
Paper we will discuss micing the drum set largely from the point of view
of AKG’s highly regarded studio mics. We also want to introduce a new
family of low-cost dynamic microphone models that are so good you’d
think they were condensers! These are the models D440, D550 and D660;
along with the D770, D880 and D112, they are ideal for the home studio
and music reinforcement on stage. They all have high overload margins in
the 145 to 150 dB, which is essential in drum micing. |

Microphone Techniques for Music Sound Reinforcement |
|
| |
Microphone
techniques (the selection and placement of microphones) have a major
influence on the audio quality of a sound reinforcement system.
In this guide, Shure application and development engineers suggest a
variety of microphone techniques for musical instruments to achieve good
results. |

Selection & Operation of Wireless Microphones |
|
| |
The purpose of
this guide is to provide reader with adequate information to select
suitable wireless equipment for a given application and to use that
equipment successfully. This guide is presented in two parts: how
wireless microphone systems work and how to make wireless microphone
systems work. The first part should be of interest to those who specify
or integrate professional wireless equipment while the second part
should be of use to anyone who regularly works with wireless microphone
systems. |

Tips on Cables & Connectors: |
 |
|
| |
Choosing the Right Mic Cable |
|
| |
In this article,
you will learn about microphone cable construction and selection with
recommended products for various types of use. We will cover:
XLR connectors, balanced and unbalanced connections, Wiring of the
different types of microphones, the right wire for microphone cables,
including shielding, and a short section for vocalists only. |
| |
|
|
|
Choosing the
Right Speaker Cable |
|
| |
Speaker cables
hook audio amplifiers to speaker cabinets. The ideal speaker cable has
zero-length wire, with no resistance, no capacitance, no inductance, and
no change in sound from amplifier to speaker. The ideal speaker
cable does not exist. However, this guide will assist you at
understanding how important cable selection is to an audio system |

Tips on Amplifiers: |

How Much Amplifier Power do I
need? |
|
| |
There is
no exact answer to the question of how much amplifier power you should
use for a particular loudspeaker. Actually, there are three separate and
very distinct issues regarding selecting amplifier power for
loudspeakers. |

|
|
|
|
Helpful Hint: |
|
Not enough gain before feedback?
Here is what you can do:
|
|
(Listed in order
of importance)
|
|
1. Move
mics closer to sources |
|
2. Move
loud-speakers farther from microphones |
|
3. Move
loud-speakers closer to listeners |
|
4. Reduce the
number of open microphones |
|
5. Use
directional microphones and loudspeakers |
|
6. Eliminate
acoustic reflections near microphones |
|
7. Reduce room
reverberation by acoustic treatment |
|
8. Use
equalizers to reduce system gain at feedback frequencies |
There are no
other solutions!
