Overview

The LINUS10 is a dual channel DSP, network, comparator and amplifier delivering 10000 W of clean power in a light weight 19”/2U package. The exceptional power of the LINUS10 ensures maximum headroom and optimal system performance for all CODA Audio touring systems.

LINUS10 ENGINE – the hybrid class H output stage topology delivers audiophile sonic accuracy with enormous headroom providing significant improvement of the system performance in dynamic and transparency.

LINUS CORE – the SHARC floating point DSP processors deliver an exceptional amount of processing power enabling the integration of sophisticated audio algorithms. The advanced signal processing includes IIR and phase linear FIR filters for perfect linearity and superior sound performance as well as look-ahead and frequency dependent limiters for increased system headroom. LiNET – transmits digital audio over a standard CAT5 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 LINUS10 can be done remotely or using the pushbuttons on the front panel.

COMPARATOR – the LINUS10 provides integrated feedback loop control for sensor controlled subwoofers. The unit has two sensor inputs connected to a 5-pol Neutrik XLR input. The Comparator’s electronic circuit loop measures the voice coil movement and adjusts the amplifier driving voltage and/or current to correct any driver inaccuracy. It is a closed feedback-loop and therefore self-optimising system in which the driver confirms precisely the power it needs to produce exactly the original audio signal. The key advantage is a very extended and controlled response. Any distortion produced by the driver or the enclosure is instantly corrected by the feedback.

AUX – integrated evacuation message contact in accordance with DIN EN 60849.

LINUS Control – Ethernet based graphical user interface for fast and flexible system configuration, tuning and control, intuitive and straight forward system design.
