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
Custom configurations available	Contact: Magnatec
