Microphone Basics

Wireless Microphones - The Basics

•Every wireless microphone system must operate on a specific frequency range.

•The government dictates the frequency ranges available for use with consumer wireless devices.

•Wireless frequencies are shared with TV stations, communications equipment and a large number of wireless microphone systems.

•Because of frequency sharing, there is always at least a small chance that someone else in the area might be using the same frequency as your wireless system.

•There must be one transmitter and one receiver to make a complete wireless system, and they both must be on the same frequency.

•If the frequencies of any two wireless systems are too close together, interference is likely, and one or both systems will probably be compromised.

•The practical maximum operating range of a wireless system will vary from as little as 100 feet (30 m) in heavily crowded indoor situations to 150 feet (40 m) In low crowded situation.

•Wireless receivers must have either one or two external antennas, and there should be a clear open-air path between these antennas and the transmitter.

•Weak or worn-out transmitter batteries are a common cause of wireless problems, including complete failure, poor range, distorted audio and interference.

Microphone Position

The DA-2277 wireless microphones are ideal for close-up vocals and can be held in the hand or mounted on a microphone stand. The most common applications and placement techniques are listed below. Keep in mind that microphone technique is largely a matter of personal taste— there is no one "correct" microphone position.

Lead & Backup Vocals

Lips should be less than 3" from or even touching the windscreen on an axis to the microphone. Doing this creates a robust sound, emphasizes bass and provides maximum isolation from other sources.

Speech

When giving a speech or simply speaking, place the microphone 4" to 10" away from the mouth, just above nose height for a natural sound with reduced bass. You can also place the microphone 8" to 16" away from the mouth, slightly off to one side, for a more "distant" sound with highly reduced bass and minimal "s" sounds.

Proximity Effect

When the sound source is less than 1/4 in. from the microphone, the microphone boosts bass frequencies

(by 6 to 10 dB at 100 Hz), creating a warmer and richer bass sound than when farther away. This effect, known as proximity effect, happens only in unidirectional dynamic microphones like those used with the DA-2277.
