DAC ONE
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.

Architecture
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.

Versions available
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.

DAC TWO
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.
Architecture
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 digital section is running on 5 Volt DC  while the analog section is running on max.  symmetrical +/- 12 Volts. Both positive or negative reference voltages can be used and give a fully symmetrical voltage swing. The Dac Two can handle real 24  bit formats and brings linearity down to -144dB.

EVA
The EVA mother board is designed for evaluation of our dac modules. The board is self supporting and can be used for coaxial S/PDIF signals up to 192 kHz sampling rate. By removing three jumpers the board can  be used in conjunction with one of our DAI interface boards which gives you fully control but also can be used with other digital sources . Digital formats like RJ16,RJ24 and I2S can be used depends on jumper settings on the board.  On demand special versions can be made. Please ask our development dept. for more information. As standard the EVA will be delivered including the Dac One modules.

DAI ONE

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.

Mono Dac motherboard
The Mono DAC mother board is designed for both “Single Ended” and “Balanced” use at the same time. The board can be used in conjunction with one of our DAI interface boards which gives you fully control.The board can be used with other digital sources like CD players music servers or USB interfaces. Digital formats like RJ16,RJ24 and I2S can be set by jumper settings on the board.  In conjunction with the DAI interface One  the board can be set to FPGA mode which gives you enhanced resolution. On demand, special versions can be made. Please ask our development dept. for more information.

Stereo Dac Motherboard
The Stereo DAC mother board  is designed for both “Single Ended” or “Balanced” use. The board can be used in conjunction with one of our DAI interface boards which gives you fully control but also can be used with other digital sources . Digital formats like RJ16,RJ24 and I2S can be used by jumper settings on the board.  By using a tumbler switch on the back side of the board,  the reference voltages on two dacs can be swapped  and creates a Single Ended signal on the RCA outputs or a Balanced output signal on the XLR outputs. On demand special versions can be made. Please ask our development dept. for more information.

Stereo Dac Motherboard
Single ended Dac Motherboard
The “Single ended Dac Motherboard” is a solution to create a complete and “ready for use” dac
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.
