ASTATIC D104M6B Amplified CB Microphone

The ASTATIC D104M6B is an amplified ceramic power microphone designed for Citizens Band radio users. It features a built-in transistor amplifier and an external gain control for adjusting output levels. The unit connects via a standard 4-pin connector and includes a 7 ft cord for flexible placement. Its black ABS housing provides a lightweight yet durable shell for mobile or base station use.

Simple 4-Pin Install With Gain Adjustment

Installation requires plugging the 4-pin connector into a compatible CB radio and setting the external gain control to the desired level. The amplified design delivers up to 100 W output power, so proper gain staging prevents over-modulation and distortion. Users must verify their radio’s pinout matches the microphone’s 4-pin wiring to avoid no audio or damage. The 1 lb weight allows easy mounting on most standard brackets without strain.

Questions about this item

How do I confirm the 100 W output power is working after connecting the 4-Pin plug?

Key the microphone and observe the radio's RF meter or SWR indicator; a clear rise to the expected power level shows the transistor amplifier is active.

What comes in the box and what extra items are needed for installation?

The package includes the amplified ceramic microphone with a 7 ft cord, 4-Pin connector, external gain control, and ABS housing; no additional parts are required for a standard CB radio with a matching 4-Pin socket.
