• Color and Finish: Typically, the HT-820B has a discreet and professional appearance, often in neutral colors like black or beige to blend with the user’s attire.

Wireless Transmission

• Frequency Range: The HT-820B operates on a specific UHF (Ultra High Frequency) band, which helps to minimize interference and provides a stable connection over longer distances compared to VHF (Very High Frequency) systems.

• Transmission Distance: The wireless range is usually robust, allowing for a transmission distance of up to 100 meters (approximately 328 feet) under optimal conditions. This range can vary based on the environment and potential obstructions.

• Signal Stability: The system employs advanced technology to ensure a stable and clear signal, minimizing dropouts and interference. It typically includes features like automatic frequency selection to avoid conflicts with other wireless devices.

Audio Performance

• Microphone Capsule: The collar microphone is designed to capture clear and precise audio. It often features a cardioid pickup pattern, which focuses on sound from the front while rejecting noise from the sides and rear. This helps in delivering high-quality audio by reducing background noise.

• Sound Quality: The HT-820B is known for its high fidelity and low distortion. It offers a broad frequency response that ensures accurate reproduction of the speaker’s voice, making it suitable for both speaking and singing applications.

Power and Battery

• Power Source: The microphone system typically uses rechargeable batteries or standard AA batteries. Rechargeable batteries offer the convenience of reuse, while AA batteries provide a more readily available power source.

• Battery Life: Depending on the battery type and usage, the HT-820B usually provides several hours of continuous operation. Battery life can vary based on the power settings and the quality of the batteries used.

Receiver and Connectivity

• Receiver Unit: The receiver is designed to be compact and easy to integrate with existing audio equipment. It often includes an LCD or LED display for monitoring frequency and signal strength.

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

• Setup and Operation: The HT-820B system is generally user-friendly, with intuitive controls for adjusting volume, frequency, and other settings. It often includes an automatic frequency scan feature to simplify setup.

Additional Features

• Audio Compression: Some models include audio compression features to enhance the clarity and consistency of the audio signal, especially in environments with varying sound levels.

• Microphone Clip and Accessories: The collar microphone comes with a clip to secure it to clothing and may include windshields or foam covers to reduce wind noise and plosive sounds.

• Compatibility: The HT-820B is often compatible with a wide range of audio equipment, including mixers, amplifiers, and PA systems, making it a versatile choice for different audio setups.
