Yamaha PX5 — High-Performance Stereo Power Amplifier

The Yamaha PX5 is a powerful, efficient 2-channel amplifier built to excel in live sound, installations, and demanding pro-audio environments. Featuring Yamaha’s modern Class-D amplification design, it delivers strong output in a compact format while maintaining clarity, reliability, and system flexibility.

Key Features & Benefits

• Powerful Output

  • 500 W per channel into 8 Ω

  • 800 W per channel into 4 Ω

  • In Power Boost mode, it can deliver 800 W into 8 Ω (mono) or even higher burst power (e.g. ~1,200 W into 4 Ω)

  • Supports stable 2 Ω loads, giving headroom for challenging speaker demands

• Class-D Amplification
  The PX5’s Class-D engine provides high efficiency, reduced heat generation, and lightweight performance — ideal for mobile rigs or long operation.

• Advanced Signal Processing
  The amplifier includes onboard digital features:

  • D-CONTOUR selectable modes (FOH/MAIN, MONITOR, OFF)

  • HPF / LPF filters with adjustable cutoff points and polarity control

  • Delay (up to 74 ms) and speaker processing (6-band parametric EQ + limiter + delay per channel)

  • Input Summing capabilities

• Connectivity & Output Options

  • Inputs: Balanced XLR and ¼″ TRS

  • Outputs: Neutrik Speakon NL4, binding posts, ¼″ jacks

  • Multiple output choices make it compatible with varied speaker wiring setups

• Robust Protection & Cooling
  Built to endure tough stage environments, the PX5 features:

  • Thermal limiting, overcurrent and overvoltage protection

  • Output muting and automatic recovery

  • Dual 16-step variable-speed fans with front-to-rear airflow

• Low Latency & Precision
  End-to-end latency from analog input to output is about 1.5 ms, ensuring tight integration with DSPs and digital mixers.

• Presets & Flexibility
  It supports 8 user presets, and ships with factory speaker presets for Yamaha passive cabinets, giving you fast setup and consistency across venues.

Technical Snapshot

Why the PX5 Stands Out

• Balances power, efficiency, and digital flexibility — a modern choice for both mobile and installed systems.

• Its DSP features (EQ, delay, filters) save you from external gear and streamline integration.

• Robust protection and thermal design make it dependable under sustained loads.

• The compact form factor and lightweight Class-D design make it ideal for touring or multi-unit deployments.
