The NOVA HDC48 controller takes audio processing to the next level with new audio converters and advanced DSP algorithms that make full use of the processing power offered by the latest 4th generation SHARC DSPs.

Unique to the industry on the HDC48 are the revolutionary new LIR Linear Phase crossover filters, and for the ultimate in driver protection with maximum SPL, the new VX Limiters. These are not marketing gimmicks; they are carefully implemented, powerful tools that enable maximum performance from NOVA sound systems. The NOVA HDC48 system controller is a high performance, easy to use signal processor for loudspeaker systems, providing processing for up to 4 inputs and 8 outputs. Taking advantage of the latest advances in analogue to digital conversion and digital signal processing technologies the unit achieves performance levels higher than all previous devices. The HDC48 provides generous amounts of signal processing capability and a wide variety of crossover shapes.


FIR Shelving EQ
The input high shelf EQ is implemented using a “Finite Impulse Response” (FIR) filter, which has a linear phase response; resulting in all frequencies delayed equally.

High Pass Filtering
To avoid unnecessary inter-band phase shifts common in many competing products, the HDC48 provides high-pass filtering on the inputs rather than forcing you to apply ‘system’ high-pass filtering on the low crossover bands.

Extensive Limiter Suite
The innovative limiter suite which includes:
•  VX limiters: Dynamic control for passive 2-way enclosures
•  Xmax excursion limiters: Dynamic impact whilst effectively protecting drivers
•  Tmax thermal modelling limiters:Regulation limiters, addressing long term overload
•  Overshoot Limiters: Governs the amplitude of transient signals, retaining average power
whilst constraining peaks

AES3 and Digital Network Audio
The HDC48 offers AES3 inputs and outputs switchable in pairs as standard.
The Dante audio networking card is available as option.
