YAMAHA P2500S
型  號： P2500S
簡  介： Robust Power Output, Superior Audio Quality, and Efficient Operation
Versatile I/O and Yamaha Speaker Processing in power amplifiers that deliver high performance as well as economy.
  詳 細 說 明
Yamaha's audio engineers have specifically designed the new 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.
Power is plentiful, ranging from 3200 watts from the P7000S to 1300 watts from the P2500S in 4 ohms bridged mode. If you want the perfect power amplifier for pair of Club S115s with a 500-watt program rating, for example, the P5000S with 500-watts per channel into 8 ohms is the obvious choice.
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.
