LD Systems DSP 44 K

LD Systems DSP 44 K Product Details

Description

The LD Systems DSP 44 K is a Dante-capable four-channel power amplifier with DSP and 2 temperature-controlled fans. The professional four-channel power amplifier has extensive DSP functions and a Dante™ interface. The protocol developed by Audinate offers a very simple solution to transmit digital audio data with extremely low latency in Ethernet networks through automatic configuration. With an output of 1,200 watts per channel and 2 x 2,400 watts in bridge mode, the DSP 44 K delivers powerful performance and uncompromising sound quality.
