雅馬哈 YAMAHA P7000S 專業(yè)音頻功率放大器
一直在努力設(shè)計一種不僅僅可完成清晰功率輸出的全新功率放大器的YAMAHA工程師們,設(shè)計出P-Series功率放大器,它可提供極其高效的大輸出功率,通過優(yōu)化可適用于流行俱樂部或R-Series揚聲器。大功率輸出首先反映在額定功率上,對于P7000S高達3200W,而在P2500S的4Ω電橋中也高達1300W.
由于采用YAMAHA獨特的EEEngine技術(shù),可獲得高效率運行.另外,所有P-Series功率放大器都配有YAMAHA獨創(chuàng)的YS處理功能(YAMAHA揚聲器處理功能),可按照俱樂部或R-Series揚聲器的特殊響應(yīng)裁剪輸出,獲得超級音質(zhì)和性能。
該系列還配置XLR和1/4英寸TRS輸入以及Neutrik Speakon、耳機插口、5路集成端子輸出，非常適合快速、靈活的輸出?？蓲呙璧母咄ɑ虻屯V波器，能用來裁剪輸出以匹配任何揚聲器系統(tǒng)，并且所有單元都濃縮在經(jīng)久耐用的小型化2U底盤上，還配有可變速冷卻風(fēng)扇。
P7000S輸出功率高達3200W，這表明這些功率放大器裝入系統(tǒng)后可提供專業(yè)品質(zhì)的功率輸出。除了具有大眾化價格外，YAMAHA獨特的EEEngine技術(shù)可提供高效的運行，通過減低AC功率消耗和熱量生成，最終降低使用成本，從而進一步為您節(jié)省開支。
P-Series功率放大器與任何揚聲器搭配都可提供完美的音質(zhì)，如果在P-Series中配置YAMAHA獨創(chuàng)的YS處理功能（YAMAHA揚聲器處理功能），則可通過裁剪其功率和性能精度，實現(xiàn)與YAMAHA R-Series或俱樂部揚聲器的完美匹配。
Yamaha P7000S P Series II Stereo Power Amplifier (1000 Watts)
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.
