Types of Wireless Lavalier Microphones
Lavalier microphones on the market can be broadly categorized into wired and wireless types. The wireless lavalier microphones are further divided into two types: UHF wireless lavalier microphones and 2.4GHz wireless system lavalier microphones.
1. UHF Wireless System with Lavalier Microphone
The UHF wireless system includes a transmitter (mic), receiver, lavalier microphone, audio adapter cable, battery, camera cold shoe, and windproof sponge cover. This type uses UHF (470MHz-806MHz) wireless transmission technology, providing a stable audio signal compatible with devices such as SLR cameras, video cameras, and computers, making it suitable for film shooting and other industries. High-end UHF lavalier microphones use true diversity reception technology, allowing one receiver to support multiple transmitters simultaneously, meeting the needs of multi-person recordings.
2. 2.4GHz Wireless Digital Lavalier Microphone
This microphone type utilizes the 2.4GHz (2.4GHz-2.485GHz) digital sampling frequency band for wireless vocal transmission. It comprises a pickup microphone, bodypack transmitter (TX), receiver (RX), lithium battery, TRS junction box, and windproof sponge cover. It’s ideal for mobile phones and SLR cameras, particularly for shooting and recording Vlog videos. The 2.4GHz wireless digital frequency band technology offers stable signals, long receiving distances, strong anti-interference capabilities, and a compact, user-friendly design. The transmitter can be worn on the collar or connected to an external microphone using a 3.5mm audio cable.
Which Wireless Lavalier Microphone is Better?
Wireless lavalier microphones typically use either UHF or 2.4GHz wireless digital frequency technology. Here’s a comparison of the two:
1. UHF Wireless System
- Stability: UHF offers more stable signals due to its wider frequency band.
- Range: It provides a longer receiving distance.
- Transmission: Supports dual-channel transmission and multi-channel reception, reducing signal attenuation and cross-frequency interference.
2. 2.4GHz Wireless System
- Power Consumption: Lower power consumption and good signal confidentiality.
- Portability: Strong portability with a long transmission distance.
- Interference: Prone to interference from other devices due to the shared international standard frequency band. However, high-end models with self-frequency modulation technology can significantly reduce this interference.
