Yamaha P3200 Dual-Channel Amplifier (520 Watts x 2)

Manufacturer's Description for Yamaha P3200 Dual-Channel Amplifier (520 Watts x 2)

The "P" Series provides the user with excellent cost per watt value, building on that cost performance with efficient power consumption. Utilizing Yamaha's new EEEngine technology, these amplifiers deliver outstanding sound quality with remarkable efficiency. All of this power and performance comes in a compact 2-space rack-mount size that makes installation and transport easy. If you need transparent amplification with excellent reliability and superior performance, give the new "P" Series a close look.

Power rating for the P1600, P3200 and P4500 are 230, 520, and 720 watts per channel into 4 ohms, respectively. Yamaha's new EEEngine (Energy Efficient Engine) consumes power efficiently, which allows the amplifier to produce the same amount of output power with about half the input power required. The EEEngine outperforms other efficiency-enhancing schemes like drive voltage switching, pulse-width modulation and switching series regulators - without degrading sound quality.

In the normal stereo mode, separate input signals are routed to each channel with independent L/R signal control. An extra margin of flexibility is provided in parallel mode, which feeds a single input signal to both channels while maintaining independent L/R signal control. Bridged mono mode can be used for extra high power. The P1600, P3200, and P4500 pump out 460, 1040, and 1440 watts in bridged mono respectively, into 8-ohm loads.

Transparent amplification without sound coloration is supplied with a frequency response of 10Hz to 50 kHz. A high damping factor of >200 provides excellent bass response and total harmonic distrortion is <0.05% - perfect for today's digital sources and musical instruments.

All 3 models offer comprehensive protection designed to prevent accidental damage to the amplifier itself and any connected speakers. Power ON muting suppresses the outputs until the amplifier circuitry has stabilized. To keep the operating temperature stable, all three models are equipped with ultra-quiet variable speed cooling fans. Added protection is supplied with heat oversink protection, noise filtering, a PC limiter for short circuit protection, and an attenuator security cover to protect level settings.

Input attenuators are 31-position, dB-calibrated and allow independent L/R adjustment with smooth, noise-free control. Balanced XLR jacks, a barrier strip and balanced 1/4" phone jacks accommodate input connections. Five-way binding posts provide solid, reliable speaker connections.

By means of switching drive system, Yamaha's EEEngine technology reduces AC power requirements and heat loss while maintaining output power and sound quality. Input power is supplied through a high-efficiency current buffer. During low requirement periods, it transparently switches the input power on and off automatically as needed. As the signal becomes large, an independently responding auxiliary power line supplies the additional power, as required. The output isn't compromised because the auxiliary power line is driven by the power supply voltage, which can maintain the maximum output to the speaker load. The amplifiers make more efficient use of the AC power than conventional amplifier technology. With EEEngine technology, the electric company will wonder how you're doing it! zZounds is an authorized dealer of Yamaha products.
