DCN24
** Obsolete **

Digital Crossover Module - 2 inputs & 4 outputs

 DCN24.pdf Manual


DCN24 is a high performance digital crossover filter with equalization and delay. It features 2 balanced analogue inputs and 4 single-ended analogue outputs. The usage of very high performance Burr-Brown converters gives DCN24 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 4 output channels of 40 IIR each and 2 input channels with additional 10 IIR filters for filtering and equalization.

DCN24 has an optical isolated USB programming interface to avoid hum and noise from the PC.

The circuit board is a high quality 4 layer type which prevents noise and hum. The layout features a lot of decoupling - at supply entry and very close to all active components.

DCN24 is the heart of an active speaker management system offering a superb sound, easy installation and easy use in daily life.

The XOverWizard II software for DCN24 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 XOverWizard II 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 - Shop
