Yamaha P2500 pro power amp!

Outstanding Power and Performance
Operating in the stereo mode the P2500 puts out 250 watts per channel into 8 ohms, 20 Hz to 20 kHz with less than 0.1% THD. It is designed for safe, stable operation into low-impedance loads. Maximum power output is a substantial 350 watts into 4- ohm loads.
High- power BTL-coupled Mono Mode
It can be configured for BTL monaural operation by simply flipping a rear-panel switch. In the bridged mono mode the P2500 pumps out 700 watt
Versatile, Reliable Connectors On the rear panel
three types of input connectors are provided for maximum versatility: phone jacks, XLR type connectors, and barrier strips that provide maximum reliability in permanent installation
Thorough Circuit Protection
Power-on muting isolates the speaker outputs for approximately 6 seconds after the power is turned on. DC sensing circuitry shuts off the outputs if a DC voltage greater than +/-2 volts is detected at the output terminals. Thermal protection shuts down the system if the heat sink temperature exceeds 100deg. C, and a power limiter reduces power output if improper connections or accidental shorts result in a speaker-terminal load of less than 2 ohm
Space-saving design with efficient forced-air cooling
P-series lineup are "3U" in height, taking up a small amount of rack space. An internal thermostatically-controlled 2-speed cooling fan eliminates the need for external cooling .
Detented Input Attenuators
The input attenuators feature 41 sure detents and smooth, noise-free control.
Signal and Clip Indicators
Signal and Clip indicators are on each channel.  The signal indicators let you know when there's a signal present in the corresponding channel. The Clip indicators warn that total harmonic distortion has exceeded 1%.
