The DS4.0 is the second in a new range of Class D amplifier modules. The state-of-the-art UcD design ensures a very low output impedance resulting in an even better control of your subwoofer.
The DS4.0 has stereo inputs (both high level and line level) and one mono LFE input.
The subwoofer crossover can be defeated in case this filtering is present in the pre-amp.

It is advisable to place the amplifier in an airtight compartment ◄

Why class D?

Class D amplifiers are often chosen for their high power efficiency (>90%) and for some more advantages.

The Hypex Class D amps are based on UcD-technology and will have the following characteristic features:

●  NO ½ supply-voltage at speaker terminals
    (unlike some other amps out there...)
●  Ultrahigh-Fidelity Sound.
●  Extremely Low Output Impedance.
●  Large, Load-Independant Bandwidth.
●  Low Noise and Distortion.
●  All-Discrete Construction.
●  Differential Input.
●  Pop-Free Start/Stop Mode.
●  Short-Circuit Detection.
 

▲ UcD Class D principle. Hypex Electronics plans to introduce Class D modules this summer which are very appropriate for use in DIY projects and so on. Of course Hypex Electronics will inplement the technology in their new products to come ■
