KAC-PS4D

4-channel Digital Power Amplifer

The Heart of Kenwood Sound Amplifiers in the 2007 PS lineup pump out extraordinary power thanks to awesome technologies that only a high-fidelity specialist like Kenwood can offer. Take a look at the performance: Dual Σ (sigma) drive provides bridged output with an excellent damping factor, new K-STAT technology with a slimmer, more compact chip design reduces thermal resistance but increases power for improved sound quality, and a dual power supply with two transformers ensures steady operation even when the positive and negative loads are unstable. What's more, the digital amplifiers boast slimmer overall dimensions without any sacrifice in performance.
