Key Features of the Yamaha PX5 Power Amplifier

High-Efficiency Class-D Power with Strong Real-World Output

At its core, the Yamaha PX5 uses a newly developed Class-D amplifier engine designed for high efficiency and reduced heat, making it suitable for demanding environments while staying lightweight and reliable.

Stereo Mode Output:

• 500 watts x 2 at 8Ω

• 800 watts x 2 at 4Ω

• 500 watts x 2 at 2Ω

This flexibility makes the PX5 ideal for powering a wide variety of speaker configurations, including low-impedance systems where high current delivery is important.

Built-In DSP Processing for System Control and Consistency

Integrated Speaker Processing Without External Gear

One of the biggest strengths of the PX5 is its onboard DSP, allowing you to shape, protect, and optimize your sound system directly from the amplifier. This makes it especially valuable for professionals who want a clean rack setup with fewer external processors.

The PX5 includes intelligent processing tools such as:

• D-CONTOUR Multiband Compressor for optimized tonal balance (FOH/Main or Monitor applications)

• 6-band Parametric EQ for precise tone shaping

• Crossover Functions (HPF / LPF) for subwoofer integration or bi-amp setups

• Delay Control for speaker time alignment

• Limiter Functions to protect speakers and prevent overload

• Preset Storage for fast recall across different venues and setups

This DSP workflow gives you consistent performance from night to night, even when working with different spaces, speaker systems, and acoustic challenges.

Flexible Connectivity for Professional Sound Systems

Multiple Input and Output Options

The PX5 is designed to fit easily into modern and traditional sound system workflows, offering practical I/O for stage, rack, and installation use.

Inputs:

• 2 x XLR (balanced)

• 2 x 1/4″ TRS (balanced)

Outputs:

• 2 x SpeakON NL4 connectors

• Binding post terminals

• 1/4″ output connections (depending on system configuration)

This makes it simple to integrate with mixers, processors, and speaker systems in both portable and fixed setups.

Compact 2U Rackmount Design with Lightweight Portability

Built for Touring, Venues, and Installers

Despite its strong power rating, the PX5 remains compact and practical for transport and rack builds. It fits into standard 2U rack spaces, making it easy to pair with signal processing gear, wireless units, or digital mixers.

The PX Series is known for being lightweight without feeling fragile, which is a major advantage for:

• Touring racks

• Mobile DJ setups

• Rental companies

• Small-to-medium venue sound systems
