  • Channel independent power, Signal and clip LEDs


Pulz AD41300 is a four channel power amplifier designed and built for applications where sonic transparency and robust high power output capability are the prime criteria.

Built around an oversized classic toroidal power supply and ultra – linear Class AB output stage, Pulz AD41300 packs 7000 Watts of continuously deliverable clean audio in a 3U 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 AD41300 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 AD41300 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 AD41300 outperform the standard amplifiers currently available.
