The Audionet DAC - Digital to Analogue Converter - is a high- performance system for converting digital audio signals, which improves the quality of sound reproduction of your whole music equipment to a much higher level. Further you can individually choose between different oversampling-filters.
The power specifications on the rear must meet to your homecountry specifications. Integration If the DAC is connected with a digital signal-source (input) , e.g. DAT, CD-Player, and a (pre-) amplifier (output), the converted digital data will be offered to the outputs as analogue data.

- 1 * Toslink out - 1 * RCA in Please connect the analogue output of the DAC has to a (pre-) amplifier by two RCA wires (left and right channel). The monitor input detects by itself, if a signal is coming in and switches it into the processing circuit.

Features Conception The block diagram on the following page shows the DAC in principle. Main features are the signal processing system DSP56004 for software- controlled digital-filtering, the 20 bit noise-shaping/converting- combination SAA7350 and TDA1547, the decoupling of the converter clock from the signal source clock by a temperature regulation circuit, the...

Digital filtering The Audionet DAC has a software-controlled digital-filtering unit. The calculating is done by a signal processing system. The tonal differences between the filters allow you to adapt the sound to your individual requests. Further the filters can be exchanged.
The DAC is completely decoupled from the clock of the signal source. The internal clock is generated by two temperature regulated quartz oscillators. The digital data is read out of a dynamic 2 megabit buffer memory.
