Absolutely Digital.


FOCUX increases the efficiency of its digital cinema sound system by 100% more than the current analogue system.


This is amazing progress, which means FOCUX digital digital sound systems have become the highest performance products in the audio industry.


FOCUX released the first digital amplifiers system in cinema industry. We are proud to announce that REAL digital sound systems are available in movie theatres from now on.






Light and Thin


With 8,400 W across four channels in a single rack space at a mere 17.6lbs weight, the D series is equally versatile in touring and permanently installed racks. This is a revolutionary breakthrough!

Perfect Speech Intelligibility.

The FOCUX digital amplifier will not produce any loss and distortion like an analogue amplifier in terms of signal and sound quality; a FOCUX signal can achieve high-fidelity. Along with the FOCUX digital amplifier, its coaxial speaker can generate perfect speech intelligibility.


Extremely Efficient.

The FOCUX digital amplifier can produce more than 90% power, but the analogue amplifier can only produce about 45%, which means if both amplifiers produce the same outputs, the FOCUX digital amplifier will save more than 50% power!


More Safety.

The FOCUX digital amplifier can produce more than 90% power. In other words, less than 10% of power will be transformed to useless heating power, which is 5 times less than an analogue amplifier! Less heating power will not only extend the life of the components, but also maintain the safety, reliability, and durability of the products.
