Regulated Switch Mode Power Supply

Precise regulation maintains constant voltage on the internal rails, ensuring full output power and undistorted sound even when the mains voltage drops as much as 20% below nominal.

Lab.gruppen pioneered the use of switch mode power supplies in power amplifiers, and the latest generation of this technology plays a key role in enabling the unrivalled potential and capabilities of the D Series.

Precise regulation maintains constant voltage on the internal rails, ensuring full output power and undistorted sound even when the mains voltage drops as much as 20% below nominal. The advanced D Series power supply also incorporates an enhanced ferrite power transformer core which, compared to its iron core counterparts, dramatically reduces weight and contributes to overall efficiency.

The universal (100 – 240 V) Regulated Switch Mode Power Supply (R.SMPS) found in all D Series models provides uninterrupted power in any installation across the globe, without fail.
