Precision Power i520.4 Amplifier. Compact iON Series 4Ch Amplifier.

The Precision Power iON i520.4 is a compact 4-channel Class D amplifier engineered to deliver substantial power without demanding excessive space. It presents an ideal audio solution for modern vehicles where installation real estate is limited, or for enthusiasts aiming to upgrade their sound system with efficient, high-performance amplification.

This amplifier incorporates a highly efficient full-range Class D topology and Surface Mount Technology (SMT), ensuring robust power delivery while maintaining a low-heat producing circuit. It features comprehensive preamp adjustments, including a variable bass boost (0 to +12 dB at 45 Hz), and fixed high-pass and low-pass filters set at 80 Hz.

For versatile integration with various head units, the i520.4 is equipped with speaker-level (high-level) inputs that feature signal sensing for automatic turn-on, thereby eliminating the need for a separate remote wire. Safety is a core design principle, with 3-way protection circuitry safeguarding against thermal, overload, and speaker short conditions. A hybrid aluminum alloy heatsink further enhances thermal efficiency, allowing the amplifier to operate reliably even under demanding conditions.
