The Dac One is a modern high precision replacement for old dacs very often used in “non oversampled” systems like the old TDA 1543 and TDA 1541. It is not a pin compatible replacement but a way to build up a converter system which can meet the best systems today in terms of sound quality.
The Dac One is build up around a fast 16 bits, and very accurate R2R ladder network. To match this ladder network to real audio formats, fast glue logic is added which makes the dac compatible with RJ16, RJ24 and I2S standards.
The ladder network is designed as a current output device and to get a voltage out, an I/V converter is needed.
Depending on designers needs, the Dac One is available in both current and voltage output versions.
The Dac Two is a modern high precision dac and is fully pin compatible with our DAC One module. Based on our “forward correction technology” the DAC Two is probably the best R2R ladder dac module ever made. Due to this technology a real 24 bits performance is achieved, and probably the most easy way to build up a converter system which can meet the best systems today in terms of sound quality.
The Dac Two is build up around two fast and very accurate R2R ladder networks. To match these ladder networks to real audio formats, fast FPGA logic is added and makes the dac compatible with RJ24 and I2S standards. The Dac Two is physically split up in two sections.
The DAI ONE is our most flexible digital interface board available and dedicated to our dac boards. However the DAI ONE can also be used in conjunction with other dac boards as it has selectable digital output formats like RJ24 and I2S. Source selection can be realized by both front panel logic or by using a simple rotary selector switch. The USB board has its own linear power supply instead of using PC power coming from the USB connector. Power down function is active on standby and will reduce power consumption below 1.5 Watts, even with connected Transient dac boards.
In conjunction with our mono dac boards the FPGA/DSP “forward correction module” can be used as an option to improve resolution of the system.
system. The board contains all necessary inputs like 2x S/PDIF , 1x Optical and 1x USB.
Depending the chosen input , the board can handle up to 384kHz sampling rate. The board can
be controlled by a simple rotary switch to select the available inputs or which can be realized by a
dedicated custom made front panel. Just connecting the board to a transformer having two 10 –
12 VAC output windings and the board is ready for use.
