The Azden CM-20D is a versatile VHF wireless microphone system designed to offer flexible audio solutions for presentations, karaoke, and small-scale live vocal applications. This system is unique as it includes both a wireless handheld microphone transmitter and a wired handheld microphone, providing users with two ready-to-use options from a single package. The core component is a true-diversity VHF receiver, which utilizes dual antennas to actively select the strongest incoming signal from the wireless transmitter, minimizing dropouts and ensuring a stable audio link. Operating in the Very High Frequency band, the system is engineered for reliable performance with reduced susceptibility to interference in environments with numerous competing wireless signals, making it suitable for fixed installations like small houses of worship, conference rooms, or school auditoriums.

The included wireless handheld transmitter features a dynamic vocal capsule known for its durability and feedback resistance. It offers user-selectable frequency channels to avoid conflicts with other nearby wireless systems and is powered by standard batteries for straightforward operation. As a valuable addition, the package includes a professional wired dynamic handheld microphone, which can be used as a reliable backup, a second microphone for a host, or for situations where the absolute reliability of a wired connection is preferred. The receiver provides multiple output options, typically including both balanced XLR and unbalanced ¼-inch jacks, allowing for easy connection to a wide range of sound systems, from small powered speakers to larger mixing consoles.

Designed for user-friendly setup and operation, the receiver features clear LED indicators for power, audio level, and RF signal strength. The system is built with a focus on practicality and value, offering an all-in-one audio package that caters to users who need both wireless convenience and the guaranteed performance of a wired microphone. By combining a true-diversity VHF wireless system with a professional wired microphone, the Azden CM-20D delivers a comprehensive and flexible vocal solution for entertainers, educators, and public speakers who require dependable audio reinforcement without complexity.
