Wireless UHF Microphone System

This lightweight wireless microphone operates on UHF technology with intelligent noise reduction for clear audio. It is designed for teaching, training, speeches, and tour guiding. The system includes a built-in 3.7V 400mAh battery providing 5-6 hours of use. It offers 40 selectable frequency channels within the 550.5MHz to 589.5MHz range.

Integrated Transmitter Design

The microphone and transmitter are combined into a single handheld unit measuring approximately 30cm in length. This all-in-one construction removes the need for a separate belt-pack transmitter and connecting cable. The ABS plastic body keeps the device light for comfortable extended wear during yoga, singing, or presentations. No additional accessories are included in the package.

550.5MHz to 589.5MHz Frequency Band

The system transmits on 40 frequency points between 550.5MHz and 589.5MHz with 15dBm transmit power. Receiving sensitivity is rated at less than 106dBm with distortion below 1% at 1KHz. Buyers needing operation outside this specific UHF range or requiring licensed frequency coordination should verify local regulations before purchase.

Questions about this item

How often will I need to recharge the built-in 400mAh battery during a full day of use?

The 3.7V 400mAh battery provides 5-6 hours of operation, so a full day of continuous use will require at least one recharge.

What is the maximum transmit power before the microphone hits its output limit?

The transmit power is capped at 15dBm, which is the highest output level the microphone can deliver.

How much heat or fan noise does the microphone generate when running all day?

The microphone has no fan and its low 15dBm transmit power produces negligible heat during extended use.
