OVERVIEW

The LINUS12C is a four channel DSP networkable amplifier delivering 4x 3000 W of virtually distortion-free power in a light weight 19”/2U package. The 4 audio inputs are selectable from analog, AES3 or LiNET digital audio and are routable to any of the 4 outputs.

LINUS12C ENGINE – the class D-IC output stage topology delivers audiophile sonic accuracy with enormous headroom providing significant improvement of the system performance in dynamics and transparency.

LINUS CORE – the SHARC floating point DSP processor ensures tremendous processing power enabling the integration of sophisticated audio algorithms. The advanced signal processing includes IIR and phase linear DS-FIR filters for perfect linearity and superior sound performance as well as advanced look-ahead and frequency dependent limiters for increased system headroom and sonic fidelity under heavy use conditions.

LiNET – a robust, redundant audio transport solution that transmits digital audio over a shielded CAT5e cable. Up to 8 digital audio signals can be sent to each amplifier via LiNET, buffered and sent to the next unit via the LiNET link out for daisy chaining. The signal routing inside the LINUS12C can be done remotely or using the pushbuttons on the front panel.

LINUS Control – CODA’s intuitive  system management software provides the user a fast and flexible graphical interface for everything from system configuration and tuning,  to control and system monitoring. It is optimised for both Mac OS and Windows, including tablet and native interfaces.
