YAMAHA P-5000S 2X750W POWER AMPLIFIER

Yamaha P5000S P Series II Stereo Power Amplifier (750 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- 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.

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.

BASIC Series - Intelligent Power

BASIC - that's meeting the tightest budgets and professional requirements
in reliability, flexibility and sound. Alone or in combination with the other
products of the Bittner portfolio.
The consequent realisation of the Bittner quality standards indicates once
more our understanding of the contracting business. It underlines our philosophy
that cost consciousness has nothing to do with giving up standards. Compromise
is a word unknown to Bittner Audio!
The incorporation of detent potentiometers, clip limiter, protection circuits for
any imaginable situation, as well as a first-class production process using only
highest-quality components made the BASIC series the choice of most contractors.

Certainly more than basic!
