The Workman DM-452 is a 5-pin CB radio microphone designed to improve voice clarity and output. It features a power and echo system that amplifies even the softest voices, delivering a deeper, louder audio quality without requiring modifications to the radio. The built-in gain adjustment and variable power allow for precise control of your voice projection across the 27 MHz frequency range.

The front slider lets you adjust the echo level, while the echo time control provides added flexibility for broadcast effects. Its Mil-Spec 6-foot coiled cord ensures durability and strain relief during use. The DM-452 requires a 9-volt battery, sold separately, and fits most 5-pin Cobra and Uniden SSB radios, including the Grant model. Designed for ease of operation, it offers an economical alternative to aftermarket modifications and enhances overall audio performance for CB and 10-meter radios.
