The Ram Audio ZETTA 460 B-Stock is a rugged 4-channel power amplifier built for touring and fixed installations. It delivers up to 4 x 1500 W at 4 ohms (4 x 1450 W at 2 ohms, 4 x 1100 W at 8 ohms), with bridging options of 2 x 2900 W at 4 ohms and 2 x 3000 W at 8 ohms for flexible system design. Efficient Class H topology and the next-generation QuantaPulse switching power supply provide strong output, low heat, and consistent audio quality under demanding loads.
Reliability is central to the design, with Power Management System (PMS), Intelligent Clip Limiter (ICL), and comprehensive protection against DC, RF, shorts, thermal events, and inrush. The up-side-down airflow path helps reduce dust build-up, while Neutrik XLR inputs and Speakon outputs ensure secure, professional connectivity. A wide 90–265 V AC, 50–60 Hz operating range supports worldwide deployment.
As a B-Stock unit, it is fully tested and fully functional, with only minor cosmetic signs of previous handling. Ideal for professional PA, distributed audio, and high-power multi-zone installs where robust performance and efficiency are essential.
