The Hypex FA123 is a high-performance, three-channel plate amplifier featuring advanced DSP control and Ncore® amplification technology. Delivering 2 x 125 W + 1 x 100 W, it is perfectly suited for 2-way or 3-way active loudspeaker designs, offering an all-in-one audiophile-grade solution.
Key Features
Based on proven Ncore® amplification.
Integrated high-performance DSP.
All-in-one amplifier, power supply, and DSP module.
Transparent, neutral and low-distortion audio reproduction.
Ideal for active loudspeakers and DIY speaker projects.
Overview
The FA123 FusionAmp integrates:
A high-efficiency switch-mode power supply (SMPS).
A powerful digital signal processor (DSP).
Three Ncore-based amplifier channels.
This makes it one of the most complete and powerful solutions available for high-fidelity active speaker design. The Ncore® topology ensures extremely low THD and IMD, offering reference-grade transparency across the full power and frequency range—even at normal listening levels.
Amplification Configuration
2 x 125 W channels (can be bridged for 1 x 250 W)
1 x 100 W channel (ideal for high-frequency drivers)
Channels fully configurable via Hypex Filter Design (HFD) software
