Key Features
- 500W per Channel at 8 Ohms
- Efficient Class-D Amplifier
- Custom LSI Chip with PLL Technology
- Power Boost Mode
The Yamaha PX5 Stereo Power Amplifier delivers 500W at 8 Ohms in a lightweight chassis and is suitable for a wide variety of sound-reinforcement applications. Part of the company's PX Series of power amplifiers, it features a Class-D engine with a single custom LSI chip, and uses PLL technology for higher efficiency and lower noise. The Power Boost mode combines the power output from two channels into one, achieving significantly higher single-channel power levels (the number of channels available is then halved).

Minimum 220 / maximum 380 watts RMS. If I set the limiter on 380 watts for the ouput wattage of my amplifier, will it be okay?

Speakers ratings, should I take minimum or peak as reference to match my speakers to an amplifier?
You should take both ratings into consideration if they are provided. RMS power ratings provide a better idea of the continuous power that is provided by an amplifier or when an RMS rating is listed for a speaker, it is the amount of continuous power that a speaker can handle. Peak power ratings refer to occasional short bursts of power that an amp can provide or the amount of power in a short burst that a speaker can handle. When only peak power ratings are provided, you can determine the RMS power rating by multiplying peak power x 0.7071. For example, if an amplifier is rated at 800 watts peak power, multiply 800 x 0.7071 which equals 565.68, meaning the amp's RMS power is approximately 566 watts.

My speakers are Max 380 watts RMS, is the PX5 too powerful?
No, the PX5 is not too powerful for speakers that can handle 380 watts each. You can use an amplifier with a power rating that is up to double the amount of power that the speakers are rated for at the same impedance. For example, if your speakers are rated for 380 watts at 8 ohms and the PX5 is rated at 500 watts per channel at 8 ohms, they are compatible.
