Overview of wireless microphones

Wireless microphone is a familiar tool in everyday life, most used in entertainment, radio ... With the wireless microphone, you can both use the device and freely move around. the voice quality is still amplified, no worries about wiring.

Wireless microphones are used mainly in theater, concerts, interviews or home entertainment

Wireless microphone (wireless microphone) is a type of microphone without a physical cable connected directly to the speaker, allowing the user's voice to be transmitted "wirelessly" to the receiver. The device will operate on a PIN-powered radio transmitter mounted inside the microphone body.

The mechanism of the wireless microphone is also very simple. The device works on the principle of electromagnetic induction. Specifically, sound waves from outside will cause the membrane to vibrate according to the frequency of the sound. At this time, an alternating current appears, along the bandwidth line to the amplifier head to be amplified.

Construction of wireless microphone

Wireless microphone devices have a common structure consisting of 2 parts, that is, the inner part and the outer part.

The inside is the core of the microphone. Here the user will find vibrating membranes, coils and magnets. The microphone will work when a wire vibrates in a magnetic field, producing an induced electromotive force, vibrating simultaneously with the sound producing the induced acoustic electric power. Sound waves from outside will cause the membrane to vibrate with the frequency of the sound. Vibration under the effect of a magnetic field will generate alternating current and follow the bandwidth line to the amplifier head where it is amplified by the amplifier and mixer.

The outside is the part you can hold up while singing. On it is designed on / off switch, the top with plastic round or wire mesh and finally where the PIN is installed.

Basic types of wireless microphones

Each brand of wireless microphones will produce a variety of product lines ranging from mid-range to entry-level, from amateur to professional. High-end mic types are priced from 4 million VND or more. However, in general, the market is distributing 5 basic types of mic.

Pros - Cons of Wireless Microphones

Advantages

As one of the most popular devices on the market, Wireless Micro has a range of advantages:

- Move easily

The most obvious advantage of wireless microphones is their unlimited portability. If you are a presenter, you absolutely can walk around the stage or even downstairs to interact with the audience without losing sound quality. Plus, you can rest assured you won't trip over the cord while on the move.

- Neat space

Wireless microphone is considered the first choice for stage performances because of the ability to fine-tune the number of wires. This will provide audiences with an intuitive, easy-to-see space, free from tangles by wires on the floor.

- Solve the worry of breaking the cable

When using wired microphone for a long time, users often experience cable breakage. The cable can even disconnect itself from the amplifier, causing awkwardness if you're giving public presentations. The wireless microphone solves this problem easily.

- Easily adjust the distance between the mouth and the microphone

With the wireless microphone, you can actively adjust the distance between the mouth and the microphone easily. However, the authenticity of the sound has not changed. For singers who need to perform sound effects, wireless microphones will definitely be a powerful tool.

Defect

In addition to the above strengths, radio microphones also have some of the following shortcomings:

- Some microphones only work within short ranges.

- interference occurs while in use.

- The uptime depends on the PIN duration.

- Wireless microphones have dead spots, that is, areas where it cannot operate.

- The number of wireless microphones operating at the same place and time will be limited due to a limited number of radio channels (frequencies).

However, wireless microphones are definitely the perfect way to eliminate the entanglement of wires like traditional microphones. In addition, users will no longer worry about electrical leakage, broken or open connections on the connecting cable. So, investing in a wireless microphone will also be a good choice, right?

The basic parameters on the wireless microphone that you need to know

Which type of wireless microphone should I buy best? To answer this question, users need to master the basic parameters on the microphone to choose the most suitable product:

Sensitivity (Sensitivity)

Microphone sensitivity is the magnitude of the volume of sound at which a microphone can pick up a given signal. In other words, this is the loudness of the sound that the microphone can pick up.

Frequency Response

With this parameter, users will know the highest and lowest sound distance that the device can receive or play. For example, a microphone with a notation of the 40Hz - 16kHz frequency range, this microphone can receive and play sound at about the frequency as indicated. The wider the frequency range of microphones, the better the quality of the microphone is possible.

Impedance - Impedance

Customers can see this parameter in the data in Ohm (Ω). Wireless microphones are classified with the following 3 impedances:

Low impedance: below 600Ω. This type of microphone often uses Balanced wires: jack XLR (canon), 6 stereo cups, stable signal transmission, not affected by prolonged cord.

Average impedance: 600Ω-10,000Ω.

High impedance:> 10,000Ω. In contrast to low impedance, this wireless microphone uses Unbalanced wires: RCA jack, 6 mono cups, prone to noise when stretching more than 10 meters, causing buzzing and losing treble sound.

VHF and UHF frequencies

When buying a wireless microphone, if you see the VHF symbol on the product, this is a device with high frequency waves and capable of transmitting - receiving data within 50m. This frequency range is usually set from 150 - 216 Mhz. This type of microphone is often used for home stereo systems, meetings, karaoke or suitable for mid-range customers.

In parallel, the UHF system is capable of transmitting and receiving data at very high frequencies within a range of over 100 meters with wavelengths smaller than VHF. Therefore, the device is mainly used for professional stage spaces or outdoor use.

How do I buy the best radio microphone?

As a diversified product on the market, what kind of wireless microphone should you buy? Let WebTech360 refer to the experiences below.

- Frequency

If you buy standard UHF radio microphone 400MHz or above will give you the best sound quality. This is considered standard for many years in wireless microphones. In addition, if you need to use it for professional stage, please use devices with frequency range from 902 - 928Mhz for perfect sound support.

- Scope of work

Typically wireless microphones should have an operating range of 90 - 100m2. According to customers' opinion, the microphones with a short range often experience interference. In addition, they cannot transmit good sound when facing barriers such as podiums, desks, doors ...-

- Choose branded products

To get the best of wireless microphones, and most importantly, use branded products. This not only gives you outstanding sound quality, but also ensures safety, avoiding static electricity.

Product features diverse

Choosing to buy a wireless microphone set with features and expandability gives you a lot of benefits, such as:

Tailor-made power switch:  One of the most requested features in a wireless system is a separate mute and power (transmit) switch. When your receiver and transmitter are being operated at the same time, both should be "locked" at the same frequency. During this communication, nothing can interfere with that system, except for another system on the same frequency.

Antennas for diversity:  The dual antenna system is currently the most used in the market today.

High quality PIN:  Some products on the market of PIN design can go through 1,000 charging cycles, saving you the cost of replacing PIN.
