N-RAK 40

8-Channel Power Rack

The N-RAK 40 unified rack system was designed for optimum performance flexibility and set-up simplicity.

N-RAK concept was created as a universal platform developed to facilitate cross-rental between NEXT-proaudio’s Users worldwide and to ensure compatibility with the cabling standard of the systems. The N-RAK 40 is equipped with Powersoft X8 amplifiers, featuring Dante audio networking functionality (optionally).

The N-RAK 40 has Dante (optional), AES3 and analogue inputs for multiple connections. With the Powersoft amplifier already built in and no assembly required, it’s an easy-to-configure, all-in-one amplifier solution that eliminates the process of building amp racks.

The N-RAK 40 touring rack offers an advanced rack solution for all NEXT-proaudio’ systems covering signal and power distribution in a plug-and-play touring package. Its versatility extends to delivery as well, since its dimensions were projected to allow easy shipment on European trucks, sea containers and other transportation modes.

The fully equipped N-RAK 40 module comprises a 6U-high Custom Rack with one Powersoft X8, 2U Audio Distribution Panel in the front, and 2U Power Distribution Panel in the back. The N-RAK 40 features Armonia software for convenient, simple and standard control. The complete digital audio signal management system based on ARM Cortex A-8 processor and TI C6000 DSP platform heralds new and innovative level of signal processing, providing non-Boolean routing and mixing, multi-stage equalisation with raised-cosine, IIR and FIR filters, delay up to 4s in input processing and 200ms for time alignment, gain and polarity adjustment, crossover, peak limiters, TruePower limiters and Active DampingControl.
