Yamaha P2500S Power Amplifier (780W@8ohms or 275W x2 @8ohms)
The new P-Series Power Amplifiers deliver solid, professional-quality power in a wide range of configurations designed to suit a variety of applications. In 4 ohms bridged mode the P2500S 1300 watts. In an 8Ω stereo application, the P2500S outputs 250 watts per channel. This wide selection lets you choose the amplifier that best matches the power handling capabilities of your speaker system.
Big Power with Outstanding Efficiency
The new P-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.
The Perfect Match for Your Club Speakers
The new P-Series Power Amplifiers can be used with any loudspeaker system, but if you're using our Club Series speakers they will provide optimum power and performance. In an 8Ω stereo application, power output per P7000S channel is 700 watts (650 watts on the 230V model), the P5000S puts out 500 watts per channel, the P3500S delivers 350 watts per channel, and the P2500S outputs 250 watts per channel. This wide selection lets you choose the amplifier that best matches the power handling capabilities of your speaker system.
All four models are equipped with independent sweepable high-pass and low-pass filters on each channel so you can optimize output for subwoofer or full range systems.
Light Weight for Easy Transport and Setup
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.
To provide the most versatile connectivity possible, all four models are equipped with Neutrik speakON* output jacks and 1/4-inch output jacks for each channel, in addition to 5-way binding post. Balanced XLR and 1/4-inch TRS jacks are provided for channel input.

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.
