DCN48CAR is a high performance digital crossover filter with equalization and delay. It features 4 single-ended analogue inputs and 8 single-ended analogue outputs. The usage of high performance Analog Device codec converter gives DCN48CAR crystal clear sound and very low noise floor. The sample rate is 96 kHz to extend bandwidth and have low order analogue low pass output filtering. The resolution of converters is 24 bit and the internal signal processor resolution is 76 bit. The signal processor will be configured as 8 output channels of 20 IIR each and 4 input channels with 5 IIR filters each for filtering and equalization.

The circuit board is a high quality 4 layer type which prevents noise and hum. The layout features a lot of decoupling - in the onboard galvanic isolated SMPS power supply and very close to all active components.

DCN48CAR will be the heart of an active speaker management system offering a superb sound in any car installation. The DCN48CAR will inprove any automobil audio system!

The software is a graphical tool to manipulate with inputs, outputs, gain, crossover frequencies, crossover slopes, equalization and delay. The software has a very significant feature: The ability to import a text file containing measured driver data of frequency, sound pressure level and phase. With these data the software are able to display frequency response and more, while design are in progress. Compared to this method the “old” trial and error method seems obsolete. The software comes in two versions: A standard as described above and a special which include measurement system and optimizer. More details at the XOverWizard II page.
Please notice: The software will have to be bought seperately including the USB Dongle-key - Prices
