Turner +3B Microphone Overview

The Turner +3B is a high-impedance, amplified desk microphone that was popular in the 1970s and 1980s. It’s known for its robust build quality, sleek design with a chrome and black finish, and distinctive performance in voice communications. The microphone features a PTT (push-to-talk) bar and a volume/gain control knob, allowing users to adjust modulation levels for optimal transmission clarity.
Originally designed for use with CB radios and ham (amateur) radios, the +3B offers excellent audio response and is especially valued for its “punchy” audio that cuts through noise—making it a favorite for operators seeking strong, clear signals.
