Yamaha PX3 Power Amplifier

Compact Two-Channel Class-D Power with Built-In Speaker Processing

The Yamaha PX3 is a two-channel, 2U Class-D power amplifier that delivers 300 W x 2 into 8 Ω and 500 W x 2 into 4 Ω (1 kHz, non-clip, 20 ms burst, both channels driven). Its newly developed amplifier engine concentrates the necessary functions into a single custom LSI chip, and the whole unit weighs 6.9 kg.

Onboard DSP provides crossover, filters, delay, limiter and PEQ, together with Yamaha's D-CONTOUR multi-band dynamic processing. Config Wizard assigns optimised settings for Yamaha passive speakers, with presets for the CBR, Club, Installation and VXS/VXC series.

300 W x 2 at 8 Ω, 500 W x 2 at 4 Ω

Yamaha rates the PX3 at 300 W x 2 into 8 Ω, 500 W x 2 into 4 Ω and 300 W x 2 into 2 Ω, measured at 1 kHz, non-clip, 20 ms burst, both channels driven. That covers everything from a single pair of 8 Ω speakers to lower-impedance loads.

Power Boost mode for one high-power channel

Power Boost mode combines the output of both channels into one, giving 600 W x 1 into 8 Ω or 1,000 W x 1 into 4 Ω. It suits a single high-power-handling speaker, but halves the number of available channels.

Built-in speaker processing

Onboard processing includes input summing, high- and low-pass filters, delay of up to 74 ms and a speaker processor with 6-band PEQ, limiter and delay. D-CONTOUR multi-band dynamic processing helps keep the sound clear and consistent.

Config Wizard presets for Yamaha speakers

Config Wizard speeds up system setup by assigning optimised speaker settings. It includes presets tuned for each model in Yamaha's CBR, Club, Installation and VXS/VXC passive speaker series.

Eight user presets and panel lock

Store eight programmable presets for instant recall and save them to a USB thumb drive. A panel locking function keeps your settings safe once the system is tuned.

Professional inputs and outputs

Each channel has an XLR and a 1/4-inch TRS input, connected in parallel. Speaker outputs are provided on Neutrik speakON, binding posts and 1/4-inch phone jacks.

Q. What is the PX3's power output?

300 W x 2 into 8 Ω, 500 W x 2 into 4 Ω and 300 W x 2 into 2 Ω, all at 1 kHz, non-clip, 20 ms burst, both channels driven, as specified by Yamaha.

Q. What does Power Boost mode do?

It combines both channels into one higher-power channel – 600 W x 1 into 8 Ω or 1,000 W x 1 into 4 Ω. The amplifier then works as a single-channel unit.

Q. Which speakers have presets?

Yamaha's Config Wizard includes presets for its CBR, Club, Installation and VXS/VXC passive speaker series. For other speakers, the crossover, filters, PEQ, delay and limiter can be set manually.

Q. How much rack space does it need?

Two rack units. The PX3 measures 480 x 88 x 388 mm (W x H x D) and weighs 6.9 kg.
