- High efficiency DPT Technology
- Premium heavy duty Toroidal Transformer
- Highly sensitive CMRR balanced input stage
- Ultra low-load output capacity
- Channel independent power, Signal and clip LEDs
Built around an oversized classic toroidal power supply and ultra - linear Class AB output stage, Pulz AD4820 packs 2000 Watts of continuously deliverable clean audio in a 2U chassis.
This is made possible by the innovative dynamic tracking power controller (DPT) which fluidly adjusts the power supply rails to track the signal. As a result unwanted power dissipation in the output stages is minimized by almost 80%. The Pulz AD4820 remains relatively cool even when driving the most demanding low impedance subwoofer loads. This approach is superior to the standard SMPS based power supplies which are prone to failures and compromise the sonic purity due to interferences.
All the components used in the Pulz AD4820 are of the highest standard and from the most reputed manufacturers.
Channel independent soft clipping, level indicators, sensitivity selection, protection and high CMRR balanced input stages are the additional useful features which makes Pulz AD4820 outperform the standard amplifiers currently available.
