Super Efficient Power Amp Perfect For Club Series!

Yamaha's audio engineers have designed the new P-Series P2500S Power Amplifier as perfect mate to the popular Club Series loudspeakers. To achieve this, they provided the P2500S 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. The P2500S 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. The Yamaha P2500S features 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 professional quality power in a wide range of configurations designed to suit most any need. In a 4 Ohm bridged application, the Yamaha P2500S delivers 1300 watts. The Yamaha P2500S high power output and affordable price delivers 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 Yamaha P2500S Power Amplifiers can be used with any loudspeaker system, but if you're using Yamaha's Club Series, the power of the P2500S will maximize your system's performance. In stereo applications, power output per channel on the P2500S is 250 watts at 8 Ohms. The Yamaha P2500S is 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.

YS Processing (Yamaha Speaker Processing)
With YS Processing, you get direct compatibility with Yamaha's popular Club Series loudspeaker systems. This special circuit optimizes output from the P2500S power amplifier to match the characteristics of Club Series speaker systems delivering a signal that is precisely what the speaker requires. With Yamaha's YS Processing system, extra-smooth highs and enhanced low frequency from your Yamaha Club Series loudspeaker system is assured.

Light Weight Keeps Transport and Setup Easy
Look at the specifications and you'll notice that the Yamaha P2500S and P3500S are respectably light in weight. 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 making transport and setup less strenuous while maintaining superior audio quality.

Flexible Connectivity
To provide the most flexible connectivity possible, the Yamaha P2500S is equipped Neutrik Speakon™ output jacks, and 1/4-inch output jacks for each channel in addition to 5-way binding post. Channel inputs on the Yamaha P2500S consist of both XLR and 1/4-inch TRS jacks.

Other P2500S Features
The industrial design of the new Yamaha P2500S delivers a refined and impressive look with deep blue faceplates bordered in silver trim, handles, and mounts. The P2500S 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. The comprehensive protection in the P2500S consists of power on/off muting, DC detection, thermal protection, current limiting, and a protective cover for the attenuators is also supplied with the Yamaha P2500S.

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. The P2500S EEEngine driven amplifier can obtain the same output as a conventional amplifier with only half the power consumption!
