Metrum EVA evaluation DAC module with DAC-TWO-192 Transient R2R
Warning: Last items in stock!
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.
This version of EVA will be delivered including the DAC TWO 192kHz modules.
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 realized 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 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 gives a fully symmetrical voltage swing. The Dac Two can handle real 24 bit formats and brings linearity down to -144dB.
