Description Condition：NEW YAMAHA YAMAHA PX3 Power Amplifier PX Series” DSP-equipped high-quality sound power amplifier with high output performance and excellent signal processing capability. PX3: High-quality sound power amplifier with high output performance and excellent signal processing capability. Best-priced 500W x 2 (4Ω) / 300W x 2 (8Ω) model suitable for compact systems. Features Stereo output: 500W x 2 (4Ω) / 300W x 2 (8Ω) Power Boost Mode: 1,000W x 1 (4Ω) / 600W x 1 (8Ω) Newly designed Class D engine using custom LSI. Powerful processors such as PEQ, Crossover, filters, Delay, Limiter, etc. are built in. Presets that best match Yamaha speaker systems are provided. The UTILITY function enables various settings and monitoring for safe and secure operation. Powerful output performance. The newly designed Class D engine using Yamaha's own custom LSI applies PLL technology to the Class D amplifier to control the transfer characteristics in real time to achieve high-grade sound quality and performance and efficient drive. The amplifier is also lighter and more reliable by condensing the necessary functions into a single chip and simplifying the configuration. The conventional amplifier circuitry and component configuration have been thoroughly reviewed and advanced technologies have been incorporated to achieve a high level of the contradictory elements of low power consumption, low noise, high output, high sound quality, and high-dimensional protection functions. ■ Lineup. Four models with different power are available for various applications. The PX10 delivers 1,200 watts (4 ohms), the PX8 1,050 watts (4 ohms), the PX5 800 watts (4 ohms), and the PX3 500 watts (4 ohms) from each channel. The PX5 and PX3 can also be equipped with a “Power Boost Mode” to increase the output power per channel (the number of channels is halved). Superior Signal Processing. The PX series incorporates powerful processors such as PEQ, Crossover, filters, Delay, Limiter, etc., which are necessary for speaker processing, and can be operated from a large LCD screen UI for simple system construction without the need for external outboards. The D-CONTOUR function allows the user to set the frequency response to best suit the speaker system to which it is connected, whether it is FOH or floor monitors, and the effect can be easily adjusted. Mode settings to suit the user's knowledge and application. PX provides “Basic Mode” and “Advanced Mode” to match the user's knowledge and application. Up to eight PX amplifier settings can be saved as amplifier presets and instantly recalled for quick and easy setup. This allows for quick and easy completion of setup. These preset data can also be extracted from the USB port and copied to other PX amplifiers, which not only greatly reduces setup time, but also allows for customization to suit various scenes. ■Config Wizard and Yamaha speaker presets for optimal settings for various speakers. The Config Wizard allows you to instantly make optimal settings for various speakers. Simply set the combination of speakers to be connected, the speakers to be connected, and select the filter and crossover. When used with Yamaha speakers, the optimal settings are applied simply by selecting the combination of speakers to be connected and the settings for the speakers to be connected, since precisely tuned settings have already been incorporated for each model. In advanced mode, even more detailed settings are available, allowing you to select input signal routing, input sensitivity/amp gain, and speaker impedance. Simple input/output setup with DSP. The configuration wizard provides a total of 15 different input settings (routing) and output settings (speaker type) combinations. By simply selecting the type that best fits the configuration of each speaker system, the input/output setup can be easily completed without complicated procedures. Input settings (routing)* : DUAL / PARALLEL / SINGLE / SUM *Selectable when “Advanced Mode” is used. Output setting (speaker type): FULL+FULL / SUB+SUB / FULL+SUB / BI-AMP / FULL(MONO)* / SUB(MONO)* * * Selectable in “Advanced Mode *Selectable when using “Power Boost Mode” (PX5 and PX3 only) ■A wide variety of input/output terminals and robust hardware. Input terminals are equipped with XLR and TRS phones. Output terminals include Speakon and Phones in addition to binding posts, making it suitable for a wide variety of applications. Every detail of the hardware has been designed to meet the demands of professionals, including the handle, which is both easy to hold and robust. UTILITY for various settings and monitoring. The PX series offers a variety of panel settings, status monitoring, and data exchange. Panel locks can be set to prevent accidental operation after installation. The PX series also offers Device Information for viewing the internal status of the amplifiers, operation log display, and a function to save data to a USB memory device for quick troubleshooting.
