Description
The Yamaha PC406-DI is a high-performance Class-D power amplifier designed for professional installation applications, delivering 4 × 600W at 8Ω and 4 × 600W at 70V/100V, making it fully compatible with both low- and high-impedance speaker systems. Its versatile output options allow integrators to drive multiple speaker zones with precision and confidence, whether in retail environments, corporate facilities, or performance spaces. Compact yet powerful, the PC406-DI ensures reliable, high-quality audio performance while maintaining efficient operation, even in demanding setups.
At the heart of the PC406-DI is its 20 × 8 input matrix, which provides unmatched flexibility in routing multiple audio sources. Combined with 16-channel Dante input and output at up to 96 kHz, the amplifier can seamlessly handle digital audio distribution with low latency, integrating both analog and Dante-enabled devices. This allows the amplifier to function as a standalone system controller, expand existing matrices, or deliver complex multi-zone audio setups without requiring additional mixers or DSP units. Such capabilities make it ideal for both large-scale installations and flexible, zone-specific audio configurations.
The PC406-DI also features powerful onboard DSP tools to ensure every speaker in the system performs optimally. It includes 16-band PEQ, crossover, filters, delay, and limiter functions, alongside Yamaha-optimized speaker presets, which simplify system setup and ensure consistent audio quality. For control and management, it is fully compatible with ProVisionaire Touch and ProVisionaire Control, allowing remote operation and centralized adjustments of volume, EQ, and routing. Custom remote panels can also be provided if needed, making the PC406-DI a complete, professional solution for modern commercial audio systems that demand both power and precision.
