   Why Class D?  – the advantages.

 

For a superior sound and to care for the environment switch to Class D amplifiers.

Class D better for your ears and the environment.

With careful component choice and the use of custom ASICs, this range of class D Amplifiers achieve very high conversion efficiency with a compact overall design.

This results in:-

Very high output power from a physically small system Power Calculation
>90% efficiency High Efficiency -measurement 
Environmentally friendly - lowest Carbon footprint of amplifier geometries  
High quality sonic performance Amplifier Sound Quality
LOW THD when used open loop THD & Sound Quality
Light Weight  
Low cost for the power offered Price List
Small physical size – easy to accommodate  
Over temperature and over current protected Applications note
Low noise – typically –85db
