New Arc Audio KS Mini Packs Big Amp Power!

After walking the floors of CES we pretty much determined that thin and small were going to be the next big focus in our industry. Everybody seems to be competing to develop the thinnest speakers and subs, and smallest, low-profile amplifiers. Well, if there were a contest for the smallest amp, then Arc Audio has just taken the grand prize trophy.

Behold the new Arc Audio KS125.2 Mini amplifier. Small vehicles are starting to become more popular these days, and that also means that the space in which to fit aftermarket audio equipment is therefore getting smaller. So Arc decided to develop an amplifier that would meet the needs of today's decreasing interior real estate, but they didn't want to sacrifice sound quality, build quality, or aesthetics. According to Arc, the new KS Mini uses Class G Multi Rail switching technology allowing the amp to effortlessly produce its rated power while maintaining 80% efficiency. This means that almost all of the energy produced by the KS Mini is converted to actual power and very little is lost to heat. According to Arc:

"Following the success of the designs used in Arc Audio’s SE and KS Series amplifiers, engineer Robert Zeff incorporated Noise reducing M.I.N.E.R. board design technology into each of the KS Mini Amplifier’s. As a result, KS Mini Amplifier’s obtained the goal of a small package but with the sound, performance, and quality of a high performance amplifier."
