Highly Reliable Circuit Design

Highly Reliable Circuit Design

To prevent circuit shutdown, Pioneer’s new digital amplifier circuit “Protection Control System” senses its internal temperature and automatically moderates input level accordingly Stable Durable Circuitry lessens the risk of high input power for the unit to achieve 1-ohm connection. This design enhances the flexibility to connect multiple subwoofers to a system.
