Metrum Pavane R2R DAC

Metrum Pavane NOS R2R DAC

With that goal of creating a very special DAC in mind the designer, Cees Ruijtenberg, has during the past year developed a new DAC.

It was an unprecedented challenge, which was eventually solved by introducing an entirely new chip, which has been exclusively developed by Metrum Acoustics.

Behind the luxurious front more than new chips are concealed: The parallel driven R2R ladder networks as used in the eight DAC modules performs , especially when combined with our FPGA-driven “forward correction module”, on a higher level. This module splits up the audio samples  for each channel into new separate data streams. Each dac cluster processes a portion of the data in the most linear region of the dac chips. The result of this process is an extremely high linearity, right down to -140 dB, which gives the Pavane a realistic 24 bit dynamic range. Due to the dual mono design over the entire frequency range an extremely high channel separation of 120 dB is realized. This contributes to the flawless positioning of instruments.

In short, the Pavane is a DAC that has taken all the lessons and experiences that her designer has learned over the years, and combined them in an ambitious DAC that can fit in every system. It is musical, honours the Non-oversampling principle while simultaneously incorporating the technological progress that has been made over the years
