一直在努力设计一种不仅仅可完成清晰功率输出的全新功率放大器的YAMAHA工程师们,设计出P-Series功率放大器,它可提供极其高效的大输出功率,通过优化可适用于流行俱乐部或R-Series扬声器。大功率输出首先反映在额定功率上,对于P7000S高达3200W,而在P2500S的4Ω电桥中也高达1300W.由于采用YAMAHA独特的EEEngine技术,可获得高效率运行.另外,所有P-Series功率放大器都配有YAMAHA独创的YS处理功能(YAMAHA扬声器处理功能),可按照俱乐部或R-Series扬声器的特殊响应裁剪输出,获得超级音质和性能。

该系列还配置XLR和1/4英寸TRS输入以及Neutrik Speakon、耳机插口、5路集成端子输出，非常适合快速、灵活的输出。可扫描的高通或低通滤波器，能用来裁剪输出以匹配任何扬声器系统，并且所有单元都浓缩在经久耐用的小型化2U底盘上，还配有可变速冷却风扇。

P7000S输出功率高达3200W，P5000S达2000W，P2500S在4Ω电桥应用中达1300W，P3500S在4Ω电桥应用中达2000W,P5000S在4Ω电桥应用中达2600W,这表明这些功率放大器装入系统后可提供专业品质的功率输出。除了具有大众化价格外，YAMAHA独特的EEEngine技术可提供高效的运行，通过减低AC功率消耗和热量生成，最终降低使用成本，从而进一步为您节省开支。

P-Series功率放大器与任何扬声器搭配都可提供完美的音质，如果在P-Series中配置YAMAHA独创的YS处理功能（YAMAHA扬声器处理功能），则可通过裁剪其功率和性能精度，实现与YAMAHA R-Series或俱乐部扬声器的完美匹配。

The new P-Series amps are an ideal match to Yamaha's popular Club Series loudspeakers and deliver a robust amount of pro quality power in a wide range of configurations designed to suit most any need. To achieve this, they're designed with big power output, and equipped with YS (Yamaha Speaker) Processing to deliver a signal that is tuned to the needs of the Club Series loudspeakers. All models feature both XLR and 1/4-inch TRS inputs and Neutrik Speakon (tm), 1/4 in., 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 professional quality power in a wide range of configurations designed to suit most any need. In a 4- Ω 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-Ω 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 (tm) 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

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 low frequency from your Club Series loudspeaker system is assured.
