Yamaha's audio engineers have specifically designed the P-Series power amplifiers to be perfect companions to the popular Club Series loudspeakers. To achieve this, they made sure that the amplifiers are capable of delivering power that matches the power handling capabilities of the Club Series Speakers, and equipped them with YS Processing (Yamaha Speaker Processing) to deliver a signal that will result in optimum system performance.

Further matching precision is afforded by Yamaha's proprietary YS Processing circuit. Each P-series amplifier is equipped with this specially designed circuit so that it delivers output tailored to the specific response of the Club Series speakers. All models feature both XLR and 1/4-inch TRS inputs, and Neutrik speakON, phone plug, and 5-way binding post outputs. Other features include Yamaha's exclusive EEEngine technology for high performance with exceptional efficiency, sweepable high and low pass filters for matching output to any loudspeakers, a compact and durable 2U chassis, and variable speed cooling fans.

Big Power with Outstanding Efficiency
The 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 delivers 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 P-Series Power Amplifiers can be used with any loudspeaker system, but if you're using Yamaha's Club Series speakers they will provide optimum power and performance. In an 8O stereo application, power output per P2500S outputs 250 watts per channel. It is 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 is surprisingly light in weight, making transport and setup less of a chore.

Versatile Connectivity
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.

* speakON is a registered trademark of Neutrik AG.

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
YS Processing (Yamaha Speaker Processing) achieves optimum matching with Yamaha's 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.
