The new P-S Series Power Amplifiers deliver solid, professional-quality power in a wide range of configurations designed to suit a variety of applications. In 4 ohmas bridged mode the P7000S delivers 3200 watts, the P5000S 2600 watts, the P3500S 2000 watts, and the P2500S 1300 watts.Those on a budget will find the lineup's high power output and affordable prices offer superior quality without putting a strain on allotted funds. Further savings are realized with extremely efficient operation utilizing Yamaha's exclusive EEEngine technology, which keeps operational costs down by significantly reducing AC power consumption and heat generation.

Look at the specifications and you'll notice that the P2500S and P3500S are surprisingly light in weight, making transport and setup less of a chore. What is really impressive, however, is the difference in weight per watt when you look at the P5000S and P7000S. The use of an advanced switching power supply makes these two models very lightweight while maintaining superior audio quality.

EEEngine (Energy Efficient Engine) Technology makes more efficient use of AC power by reducing power consumption and heat generation without sacrificing output power or sound quality. When power requirements are low, the system uses a highly efficient current buffer to transparently switch input power on and off as needed. As power requirements increase, an independently responding auxiliary power line supplies additional power as required. Output isn't compromised because the auxiliary power line is driven by the power supply voltage which maintains maximum output to the speaker load.

YS Processing (Yamaha Speaker Processing) achieves optimum matching with our popular Club Series loudspeaker systems. This special circuit optimizes output from the power amplifier to match the characteristics of Club Series speaker systems, resulting in extra-smooth highs and enhanced lows.
