YAMAHA P-2500S 2X390W POWER AMPLIFIER

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- ohm
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-ohm 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.
* Speakon is the registered trademark of Neutrik AG.
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.

Solid DYNACORD technology for fixed installations at very competitive prices.
DSA power amplifiers offer a very high, stable output with high efficiency at a high performance level and are therefore the ideal choice for typical fixed installation applications. The connectivity consequently provides Phoenix type in/outs, the input level controls are located on the rear panel, also a switchable high-pass filter (50 Hz, 18 dB/oct) and a Ground Lift switch.
The POWER REMOTE connector makes the task of remote controlling the power amplifier as well as switching it on and off simple. For further remote-supervision and –control possibilities and integration into IRIS-Net networks, an optional remote control module (RCM-810) is available.

The new DEEP2 amp series features four class-H power amplifiers with toroidal core offering amplifying levels from 2 x 400 W till 2 x 810 W at 4 Ohm. During the development of this series we attached a great importance to the reliability and the durability of the amps in continuous operation, this is why we used exclusively high end and selected components for the construction of these products. The DEEP2 series features a Clip Limiter as well as every common protection circuits. These amps are 2 Ohm and 4 Ohm (bridge) stable in continuous operation. On the rear panel you will find all the common In- and Outputs.
