FPX 5.1200 | High-Performance 5-Channel Class D Amplifier – Focal FPX Series
Precision Power for Complete In-Car Systems
The Focal FPX 5.1200 is a compact 5-channel Class D amplifier engineered to deliver power, control, and musical precision in one sleek chassis. Offering 4 × 120W RMS and a dedicated 1 × 720W RMS subwoofer channel at 2 Ohms, it’s the ultimate all-in-one solution for powering an entire hi-fi system.
With its high-efficiency design, advanced crossover tuning, and remote bass control, the FPX 5.1200 achieves a perfect blend of compact form and uncompromising performance.
Dynamic Control. Tailored Sound.
Designed for flexibility, the FPX 5.1200 features an input selector (2/4/6 channels) that automatically duplicates signal paths — ensuring all five channels operate seamlessly, even when connected to a factory head unit with limited outputs.
The dedicated subwoofer channel provides complete tuning control, including:
-
Adjustable low-pass active crossover
-
Subsonic filter for protecting compact subs
-
Bass equaliser and phase alignment
-
Remote level control for on-the-fly bass adjustment
Every function has been fine-tuned to help you achieve perfect tonal balance and immersive, full-spectrum sound.
Compact Design, Colossal Output
The FPX 5.1200’s compact frame — just 337 × 175 × 57mm (13.25” × 6.8” × 2.25”) — houses a power-dense Class D architecture that stays cool and efficient even under load. Its advanced internal layout allows for optimal heat dissipation, maintaining consistent power delivery across all channels without distortion or thermal compression.
Stable at 4 Ohms and 2 Ohms, the FPX 5.1200 confidently drives both front and rear speakers along with a high-output subwoofer, making it the perfect choice for compact vehicles or premium installs with limited space.
Engineered for Thermal Precision and Reliability
The FPX 5.1200’s thick aluminium chassis functions as both a cooling system and a structural backbone. Internal components — from the oversized toroidal transformer to high-grade capacitors and switching power supply — have been chosen for long-term stability and sonic transparency.
This ensures consistent dynamic performance, delivering tight, controlled bass and crystal-clear mids and highs, even during extended listening sessions.
