The HTDZ HT-820B Handheld Wireless Microphone is a professional-grade wireless microphone designed for a wide range of live sound applications, including performances, public speaking, and presentations. It combines advanced technology with user-friendly features to deliver high-quality audio and reliable wireless performance.

Design and Build

• Microphone Type: The HTDZ HT-820B is a handheld microphone, which allows for easy maneuverability and control by the user. The design is suited for applications where the speaker or performer needs to hold the microphone directly, such as during speeches, live performances, or vocal recording.

• Build Quality: The microphone is built with a robust metal grille and durable construction to withstand the rigors of frequent use. The ergonomic handle is designed for comfort, making it easy to hold for extended periods without causing fatigue.

• Color and Finish: Typically finished in sleek black or silver, the HT-820B has a professional appearance that complements various stage and studio setups. The matte finish helps to reduce reflections and glare under stage lighting.

Wireless Transmission

• Frequency Range: The HT-820B operates on a UHF (Ultra High Frequency) band, which provides a more stable and interference-resistant signal compared to VHF systems. This ensures clearer audio transmission and fewer dropouts.

• Transmission Distance: The microphone offers a reliable wireless range, generally up to 100 meters (approximately 328 feet) in ideal conditions. This range allows users to move freely around the stage or venue while maintaining a strong signal.

• Signal Stability: Advanced technology in the HT-820B ensures a stable signal with minimal interference. The system includes features like automatic frequency scanning and selection to avoid conflicts with other wireless devices and maintain optimal performance.

Audio Performance

• Microphone Capsule: The HT-820B features a high-quality dynamic microphone capsule that provides clear and consistent audio capture. It is designed to handle high sound pressure levels, making it suitable for both vocal and instrumental applications.

• Sound Quality: The microphone delivers excellent sound quality with a balanced frequency response and low distortion. This allows for accurate reproduction of the speaker’s or performer’s voice, making it ideal for professional audio settings.

• Pickup Pattern: The HT-820B typically employs a cardioid pickup pattern, which focuses on sound coming from the front of the microphone while rejecting noise from the sides and rear. This helps in isolating the primary audio source and reducing feedback.

Power and Battery

• Power Source: The microphone is powered by either AA batteries or a rechargeable battery pack, depending on the model. Rechargeable batteries offer convenience and cost savings over time, while AA batteries provide a readily available power option.

• Battery Life: Battery life is designed to support extended use, generally providing several hours of continuous operation. The actual duration can vary based on the type of batteries used and the power settings of the microphone.

Receiver and Connectivity

• Receiver Unit: The HT-820B comes with a compact and user-friendly receiver that is easy to integrate with existing audio equipment. The receiver typically features an LCD or LED display for monitoring frequency, signal strength, and battery status.

• Output Options: The receiver usually includes multiple output options, such as XLR and 1/4” TRS outputs, which allow for compatibility with various sound systems, mixers, and amplifiers.

• Setup and Operation: The system is designed for ease of use, with straightforward controls for adjusting volume, frequency, and other settings. The automatic frequency scanning feature simplifies the setup process by finding the best available frequency.

Additional Features

• Audio Compression: Some models may include audio compression features to enhance sound consistency and clarity, especially in dynamic environments where volume levels may vary.

• Anti-Feedback Technology: The HT-820B may incorporate technologies to reduce feedback and unwanted noise, ensuring a cleaner audio signal during live performances.

• Accessories: The microphone often comes with a range of accessories, including a windscreen or foam cover to minimize plosive sounds and a carrying case for easy transport and protection.
