Get to know them!

Yamaha's PX3 dual-channel Class D power amplifier gives you more than great-sounding amplification. It packs powerful built-in processing that would normally require external PA management processing. We're talking onboard equalization for fine-tuning outputs, crossovers for integrating subs and fills, delays for correcting phase issues in large rigs, and a speaker-saving limiter. Factor in stellar sound quality, easy control via the LCD display, and its ultra-light weight, and it's clear the Yamaha PX3 stands out among power amps in its class.

Achieve better live sound with less gear, thanks to built-in PA management

Live sound engineers at Sweetwater generally turn to dedicated speaker management processors for fine-tuning their PA systems. That's why we're pleased to see the Yamaha PX series of power amps offer a ton of powerful processing built right in. Fine-tune output channels with equalization, and add limiting to protect your speakers from dangerous signal spikes. Dial in crossovers to integrate subwoofers and fill speakers. Use the built-in delay network to ensure phase coherency across all speakers in larger rigs. And all of these advanced features are easily accessible from the LCD display.

Yamaha PX3 Dual-channel Class D Power Amplifier Features:
  • Dual-channel Class D power amplifier with built-in PA management processing
  • Connectivity includes XLR and TRS inputs and speakON, binding post, and phono outputs
  • Power Boost Mode bridges the outputs to achieve double the wattage (reduces output to a single channel)
  • Built-in PA management tools such as EQ, limiting, delays, crossovers, and filters
  • LCD display for easy navigation of advanced features
Drive your live sound rig with confidence, with the Yamaha PX3 dual-channel power amp.

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
