DCN23 is a high performance digital crossover filter with equalization and delay. It features 2 balanced analogue inputs and 3 single-ended analogue outputs (of which the third has an inverted output for easy bridging at e.g. low frequencies). The usage of high performance Burr-Brown converters gives DCN23 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 holds 3 channels of 16 biquads each for filtering and equalization. DCN23 has an optical isolated USB 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.
DCN23 is the heart of an active speaker management system offering a superb sound, easy installation and easy use in daily life.
