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.

DA2277 specifications

The VocoPro DA2277 is a versatile and powerful dual wireless microphone system designed for professional audio applications. It is an ideal choice for performers, DJs, and presenters who require high-quality sound and reliability in various performance settings. With its innovative features and advanced technologies, the DA2277 sets itself apart in the crowded market of wireless microphone systems.

One of the standout features of the VocoPro DA2277 is its dual-channel receiver, which allows users to operate two wireless microphones simultaneously. This capability is especially useful for performances that require multiple speakers or vocalists, as it enables seamless switching between microphones without any interruption in audio quality. The receiver is equipped with a clear LCD display, providing real-time information on frequency, signal strength, and battery status, ensuring users can monitor their performance effectively.

The DA2277 operates in the UHF frequency range, which allows for a more stable and interference-free signal compared to VHF alternatives. This UHF technology minimizes the risk of dropouts and ensures that audio remains crisp and clear, even in crowded environments with potential wireless interference. Additionally, the system includes a wide frequency response range, ensuring that it can capture the nuances of the human voice as well as instrumentation.

Another notable characteristic of the VocoPro DA2277 is its lightweight and ergonomic handheld microphones. Designed for comfort and ease of use, these microphones feature a dynamic capsule that delivers excellent sound quality and durability, making them suitable for a variety of performance situations. The microphones also come with built-in battery life indicators, providing users with peace of mind during extended performances.

The DA2277 is also equipped with features like automatic frequency selection and infrared synchronization, making it easy to set up and operate. Users can quickly find an available frequency and sync it to the microphones, minimizing setup time and maximizing performance efficiency.

Overall, the VocoPro DA2277 combines functionality, technology, and user-friendly design, making it an excellent choice for anyone in need of a reliable and high-performing wireless microphone system. Its dual-channel capability, UHF operating range, and precise audio capture make it an essential tool for performers and presenters alike. With the DA2277, users can focus on delivering their best performances without worrying about audio quality or reliability.
