NEO12004DSP - 1200W RMS Class D 4-Channel Amplifier

Versatile Power Meets Precision Control

The Diamond Audio NEO12004DSP is the definitive solution for audiophiles seeking the perfect balance of multi-channel power and sophisticated tuning. As a high-efficiency Class D 4-channel amplifier, it delivers a robust 1200W RMS total output, providing the versatile power needed to drive high-end component speakers or subwoofers when bridged at 600W x 2 @ 4Ω, all while maintaining the pure sonic clarity Diamond Audio is known for.

Advanced Full DSP Integration

Unlike standard multi-channel amplifiers, the NEO12004DSP features an integrated full-service Digital Signal Processor (DSP). With 31 bands of parametric EQ per channel, precise crossovers, time delay, and channel linking, you have total command over your entire soundstage. Whether tuning via PC or Android, the NEO Series provides a professional-grade interface to calibrate your system for any acoustic environment.

Seamless OEM & EV Integration

Designed for the modern vehicle landscape, the NEO12004DSP excels in system integration. It features high-voltage signal inputs (up to 20V) and selectable onboard load resistors (10Ω, 20Ω, 60Ω, and 20kΩ) to interface seamlessly with complex factory OEM systems. Furthermore, its EV-friendly voltage compatibility (8V–17V) ensures stable performance in electric and hybrid vehicles without compromising the vehicle’s electrical integrity.

Versatile & Rugged Engineering

Built to perform in diverse environments, the NEO12004DSP features a marine-ready, water-resistant chassis, making it an ideal choice for high-end car audio, marine, and powersports installations. Its compact footprint, staggered RCA connections, and high-current quick-connect power blocks ensure a clean, professional installation even in tight spaces, offering a powerful four-channel solution that is as durable as it is precise.
