MXA-8400  8 channel Digital Power Amplifier

The MXA-8400 is the most powerful product from Lyngdorf Audio ever, and it will challenge the capacity of your mains power supply with its peak output of no less than 3.2 KW. It is more than just another high-end amplifier – it is a shift in amplifier paradigms through its novel use of negative feedback (NFB).

Exceptional 137db s/n ratio and lowest harmonic distortion of any amplifier!

The output section of the MXA-8400 is a completely new electrical Lyngdorf Audio design based on the optimal use of NFB in audio amplifiers. NFB is an arrangement in which an amplifier is made to respond to a fraction of its own output signal in opposite phase in addition to the normal input signal. It effectively reduces distortion and increases linearity.

With a circuitry design focused on reducing negative elements outside the NFB loop, the MXA-8400 is a very powerful amplifier with a linearity and overall performance not seen before in the audio world. Even when operating over its maximum specification, clipping in the output stage will be recovered in both voltage and current domains. It is immune to out-of-band noise on the input signal and insensitive to difficult speaker loads. A fan-less design, extremely low noise floor, and extreme dynamic performance makes the MXA-8400 optimal for use with cinema installations in order to preserve the cinematic illusion.

The MXA-8400 is, like all Lyngdorf Audio electronics, built to the highest industry standards. With no noisy fans, the cabinet functions as heatsink for the output stage. Normal ventilation in a rack is enough. Finally, the MXA-8400 undergoes a 24 hour of burn-in. This ensures that you will not only have ultimate performance but also a product with probably the highest reliability in the industry.
