Description

The Salcon Dual Channel Gain (921) is a small electronic module that includes two identical amplifiers side by side—think of it like having two mini boosters in one package. It’s designed to quietly and cleanly make weak signals stronger, so it’s often used in audio gear, sensor systems, or hobby electronics projects. You power it up and plug in your low‑level input, and what you get out is a larger version of your original signal—just louder or more pronounced, without noticeable noise.
