Astatic 636L-4B Microphone Classic Edition is a renowned microphone known for its exceptional performance and durability.


The Astatic Model 636L-4B is a noise-cancelling dynamic microphone designed for close-talking hand-held CB, Amateur Radio, and SSB communications applications. It features a rugged and dependable dynamic element, the same element used in professional two-way radios, housed in a classic tear-drop style design. The microphone's frequency response is tailored for optimal intelligibility and clarity in voice communications, with a 360 minimization of background noise. A soft lip guard is strategically positioned to ensure proper close-talk spacing for the operator's comfort.

This model has a six-wire coil cord that allows various hookup options, including relay, electronic, or compatibility with almost any transmitter/transceiver. The microphone has a low impedance output and is equipped with a long-lasting DPDT switch that is factory-wired and normally open. The Astatic Model 636L-4B is designed with an impedance of 200 ohms, which matches 50 to 1000 Ohms, offering versatility in connectivity. The connector is stripped, tinned, or configured with a four-pin (DX1) DIN for convenience.

Weighing 284 grams (10 oz.), the microphone is housed in durable, high-impact, moulded black Cycolac material. The cable is a six-wire, five-conductor (one conductor shielded) coiled cord that extends to 2.3 m (7 1/2 ft.), with a strain relief bushing to protect against cable breakage at the microphone housing. The Astatic Model 636L-4B is a reliable and versatile option for those seeking high-quality audio transmission in various communication settings.
