The DC4000 is a digital 2-in / 4-out speaker management matrix system with an internal resolution of 32 bit and 96 kHz sampling rate. The DC4000 is equipped with 2 analog inputs, 4 analog outputs and two remote-connectors (USB and RS485). The use of modern and fast DSPs enables a latency (analog to analog) of 0,625 ms only. Each input channel includes 6 equalizers (with low-shelf, high-shelf and parametric function), and a delay function. The polarity of each input channel can be switched from + to -. Each output channel includes 6 equalizers (with low-shelf, high-shelf and parametric function) and a delay function. The HPF (high-pass filter) and the LPF (low-pass filter) is part of each output channel. Both offer three different operation modes: Linkwitz-Riley, Butterworth and Bessel (up to 48 dB/Oct). Each output channel includes a high performance limiter. The integrated flash memory chip offers space for 30 presets which can be loaded via the preset-menu, three default-buttons or the PC remote software.

DC 8000




32-bit digital 4-in/8-out speaker management system
The DC8000 is a digital 4-in / 8-out speaker management matrix system with an internal resolution of 32 bit and 96 kHz sampling rate. The DC8000 is equipped with 4 analog and digital (AES/EBU© format) inputs, 8 analog outputs and two RS485 remote-connectors. The use of modern and fast DSPs enables a latency (analog to analog) of 0,625 ms only. Each input channel includes 8 equalizers (with low-shelf, high-shelf and parametric function), a delay function and a noise gate. The polarity of each input channel can be switched from + to -. Each output channel includes 6 equalizers (with low-shelf, high-shelf and parametric function) and a delay function. The HPF (high-pass filter) and the LPF (low-pass filter) is part of each output channel. Both offer three different operation modes: Linkwitz-Riley, Butterworth and Bessel (up to 48 dB/Oct).

HDC 48
Next-Level Audio Controller with Class-Leading Sonic Performance
The HDC48 takes audio performance 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 allow to extract the maximum performance from NOVA sound systems, safely. The HDC48 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. Three rotary encoders, illuminated buttons and graphical display provide a rapid, intuitive and userfriendly control interface.

Drive Module Concept
The powerful drive module concept allows for abstraction from device centric to speaker based control. The HDC48 uses drive module presets, which are defined as a number of outputs driven from one DSP input. This system allows for better flexibility and greater functionality when loading and storing presets. Drive modules allow for a less processor-centric and more speakerorientated system design. The HDC48 allows 50 drive module presets to be stored. Presets are stored permanently inside the HDC48 and so will always be available even if the HDC48 is not being used with the NOVA.Net software.


Unique LIR Filtering
The LIR linear phase crossover shapes give FIR-like performance without the drawbacks. The linear phase HF system EQ profiling provides perfect integration between enclosures. As well as the standard Butterworth, Bessel, Linkwitz-Riley and Hardman filters, the HDC48 offers a unique “Linear Impulse Response” (LIR) crossover filter which gives a linear phase crossover that has a constant delay regardless of frequency (unlike other types of crossover which delay different frequencies to a different extent, thus smearing the arrival time). The LIR crossover can thus be described as having a flat group delay response, and thus entirely free of group delay distortion, this is exactly the same as can be provided by common FIR filtering but without the complications and disadvantages inherent with the FIR technique. The shape of the LIR crossover filter is similar to a 4th order Linkwitz-Riley filter, and maintains zero phase difference between the adjacent bands across the crossover region to keep the polar response rock steady. As we also employ phase matching on our Bessel filters, adjacent bands are in-phase throughout the crossover region. 


FIR Shelving EQ
The input high shelf EQ is implemented using a „Finite Impulse Response“ (FIR) filter, and exhibits a linear phase response; that is all frequencies are delayed by the same amount.


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.


NOVA.Net PC App
The NOVA.Net „System Engineer“ PC app is much more
than just a remote control panel for an HDC48. The PC
app and any connected device(s) become intimately
intertwined, faithfully duplicating any control adjustments
whether they are made in the application or on the front
panel of the device itself. Adjust a gain control on the
device, and watch the gain value in the app smoothly slide
in sympathy. Each input and each output can be
named in the application. These names not only appear for
the user  on the application control panels, but also show when scrolling through the inputs and outputs on the device itself. Even a HDC48 firmware update can be made easily via the network.


High Speed Interface
The HDC48 includes a high speed ethernet communications interface that supports DHCP, static-IP and auto-IP and direct connection to a computer without the need for a router or a switch.
