Yamaha's audio engineers have designed the new P-Series Power Amplifiers as perfect mates to the popular Club Series loudspeakers. To achieve this, they provided them with big power output 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 is tuned to the needs of these loudspeakers. Further matching is found in Yamaha's proprietary YS Processing. Each model is equipped with this specially designed circuit that delivers output tailored to the specific response of the Club Series speakers for superior audio quality and performance. All models feature both XLR and 1/4-inch TRS inputs and Neutrik Speakon, phone plug, and 5-way binding post outputs to make connections quick and easy. Other features include Yamaha's exclusive EEEngine technology which delivers high performance with exceptional efficiency, sweepable high and low pass filters for optimizing output to any loudspeakers, compact and durable 2U chassis, and variable speed cooling fans.

Big Output Power Delivered with Great Efficiency
The new P-Series Power Amplifiers deliver a robust amount of professionalquality power in a wide range of configurations designed to suit most any need. In a 4- ohm bridged application, the P7000S delivers 3200 watts, the P5000S delivers 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 deliver higher quality without putting a strain on 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 with Your Club Speakers
The new P-Series Power Amplifiers can be used with any loudspeaker system, but if you're using our Club Series, they will provide power and performance tailored to deliver maximum performance from your system. In an 8-ohm stereo application power output per channel on the P7000S is 700 watts, the P5000S 500 watts, the P3500S 350 watts, and the P2500S 250 watts. 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 and low pass filters on each channel so you can optimize output for subwoofer or full range systems to provide peak audio quality and performance from any speaker system you may be using.

Light Weight Keeps Transport and Setup Easy
Look at the specifications and you'll notice that the P2500S and P3500S are respectably light in weight making transport and setup less strenuous. What's amazing though, is the comparison in weight per watt when you look at the P5000S and P7000S. The use of a switching power supply makes these two models very lightweight while maintaining superior audio quality.

Flexible Connectivity
To provide the most flexible connectivity possible, all four models are equipped Neutrik Speakon?output jacks, and 1/4-inch output jacks for each channel in addition to 5-way binding post. Channel inputs consist of both XLR and 1/4-inch TRS jacks.

Other Features
The new P-Series' industrial design delivers a refined and impressive look with deep blue faceplates bordered in silver trim, handles, and mounts. The chassis is specially designed to provide added durability and strength. Continuously variable-speed fans mounted internally on either side of the front panel offer quiet, efficient cooling. Comprehensive protection consists of power on/off muting, DC detection, thermal protection, current limiting, and a protective cover for the attenuators is also supplied.

EEEngine (Energy Efficient Engine) Technology makes more efficient use of AC power by reducing power consumption and heat generation without degrading 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, as the auxiliary power line is driven by the power supply voltage, which maintains maximum output to the speaker load.

YS Processing
With YS Processing (Yamaha Speaker Processing), you get direct compatibility 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 delivering a signal that is precisely what the speaker requires. With the YS Processing system, extra-smooth highs and enhanced lowfrequency from your Club Series loudspeaker system is assured.
