Four basics about dual wireless microphone

Wireless microphone systems enable artists, musicians, presenters, content creators, interviewers, and actors to roam freely indoors and outdoors without the inconvenience of long cable. They are essential for recording voices, sound effects, instruments, and ambiance. If you want to record two sound sources at the same time, dual wireless microphone will be your first choice. In this article, we will talk about the basics which include:

  1. What is consist of in it?
  2. Introduction to different bandwidths
  3. Factors to consider when get purchasing.
  4. How to avoid dropout, and interference when using.

Video: Dual channel wireless microphone introduction

Every dual wireless microphone system consists of two transmitters that are typically worn or held by the talent, and a receiver, which receives the wireless signal from transmitters, transforms it to audio and feeds the audio to your mixer or power amp through a cable.

It comes in three types. Handheld wireless microphones include the transmitter into the grip or base of the microphone. A bodypack transmitter that clips on a belt or fits in the pocket is often used with wireless lavalier mic. Headset microphones may include the transmitter onto a neckband or utilize a bodypack.

Bandwidth explained: VHF, UHF, and 2.4G

Dual wireless microphone generally operates in three frequency ranges, including VHF, UHF, and 2.4G.

VHF: VHF, or "very high frequency," refers to the radio frequency spectrum between 49 and 216MHz. The FCC splits VHF into two bands: low (49-108MHz) and high (169-216MHz). Dual VHF wireless microphone system is often less expensive, but it has fewer accessible channels and needs extremely long antennas.

UHF: Dual UHF wireless microphone operates in the 450-952 MHz Ultra High Frequency range. Diversity receivers, which employ two separate antennas to boost reception, are highly effective in the UHF band. Because UHF systems have shorter wavelengths, they can use shorter antennas. However, the UHF spectrum is susceptible to interference from TV stations. And it no longer has access to 600 MHz bands (614-698 MHz) since the FCC reassigned it for wireless broadband use.

2.4G: Many low-cost and digital wireless microphone systems operate in the 2.4 GHz ISM band (2.400-2.483 GHz), which allows for worldwide license-free operation and relatively small antennas. If you just need one or two wireless channels, the 2.4 GHz band is ideal.

Four factors to consider for best dual wireless microphone

Making your choice of the best dual wireless microphone for your filmmaking might be difficult. But don't worry. We offer a few tips to help you with your pick. Below we list some factors that you should take into consideration:


Consider the product's function, as it is critical. Check to see whether the specifications fit your requirements. Consider buying one that can last a long time. Learn about the specifications and features to determine their use for you.


Go to online shops and look up the options. Then compare prices and hunt for deals. Don't forget to account for delivery costs. Once you've found the greatest value, you can choose one to meet your needs.


Price and brand are partially related. High-end brands typically bill more. However, a higher price does not always imply a superior option. So, choose the brand that best matches your requirements.

Three tips to make dual wireless microphone sound better

Make proper setup. Proper setup will extend the range of your dual wireless microphone and lessen the likelihood of dropouts. Place the receiver at a location that allows you to keep a "line of sight" between the transmitter and the receiver.

Metal items, walls, or a large crowd should not be placed between your receiver's antenna and your transmitter. Elevate your antennas above any obstacles if feasible. Place the transmitter in the best possible location and, if required, connect it to your mixer with a lengthy connection.

Make sure you and your microphone users are aware of the system's range limitations. During your sound check, go around to see how far you can go without encountering any audio problems.

Make use of high-quality batteries. Pay attention to your battery life indicators and replace or recharge those that are showing low power. When your batteries are going to run out of power, you may experience signal distortion and dropouts.

Avoid interference from other wireless systems. Many systems automatically select a clear channel when you set it up to help you avoid distractions. But what works during a sound check may not work during a show. Why? Because another wireless system nearby may not be working when sound check is taken. Check again before the show starts.

If your dual wireless microphone receiver contains an RF (radio frequency) level meter, you can use this method to identify your interference problem. Turn off your transmitter and observe whether the receiver is still receiving a signal. If it is, switch channels until you locate one with no competing signals.

Set proper gain. The majority of wireless microphone transmitters offer a gain control. Distortion can occur if the gain is set too high. If it's set too low, your sound guy may attempt to compensate by increasing the level on the mixing board. This "gain staging" issue will result in a noisy sound.
