Yamaha PC412-DI Class-D Hi-Z Power Amplifier with Dante I/O

The Yamaha PC412-DI is a high-power Class-D installation amplifier delivering 4 × 1200W at 8Ω and 4 × 1200W at 70V/100V, making it fully compatible with both low- and high-impedance speaker systems. Designed for professional audio installations, it combines powerful amplification with advanced system flexibility, allowing integrators to drive multiple speaker zones reliably and efficiently while maintaining precise sound quality across all channels.

At the core of the PC412-DI is its 20 × 8 input matrix, which enables flexible routing of multiple audio sources, even in systems without additional mixers or DSP. Combined with 16-channel Dante input/output at up to 96 kHz, the amplifier supports low-latency digital audio distribution and redundant connections, allowing precise routing of analog and digital signals to speakers or other Dante-equipped devices. This flexibility makes it ideal for complex multi-zone setups, mixer-less systems, or as a supplementary matrix to expand existing installations.

Equipped with powerful onboard DSP, the PC412-DI offers 16-band PEQ, crossover, filters, delay, FIR filtering, and RMS/peak limiting, along with Yamaha-optimized speaker presets for fast and accurate system setup. Control and monitoring are streamlined through ProVisionaire Touch, ProVisionaire Control, and the dedicated ProVisionaire Amp Editor, allowing individual or grouped amplifier adjustments for EQ, delay, and volume from a single interface. Detachable handles and replaceable filters ensure easy maintenance, making the PC412-DI a complete, reliable, and professional solution for modern commercial audio installations.
