OVERVIEW

The LINUS6.4 is a four-channel DSP networkable installation amplifier delivering 4 x 1500 W of clean power in a convenient and lightweight 19”/1U package. 

Advanced Class D discrete power stages with DC-coupled DACs, together with a high-efficiency SMPS with PFC to provide unrivalled power density and minimal thermal dissipation. 

The innovative PCB layout design integrates DSP, four amplifiers, and SMPS on a single PCB for enhanced sound quality, pinpoint control, and rugged protection. 

The four audio inputs are selectable, you can choose between analog, LiNET, Dante digital audio network and simply and easily route to any of the four outputs via the input matrix.

The advanced DSP processor enables the integration of sophisticated audio algorithms including phase linear DS-FIR filters, these provide perfect linearity and superior sound performance, plus advanced look-ahead and frequency-dependent limiters. The end result is increased system headroom and sonic fidelity, even under heavy use conditions.
