Metrum Acoustics Hex DAC

Metrum Acoustics

After choosing the Aurix for headphone monitoring, STS Digital has decided to use our Hex dac to monitor the entire recording process. It is due to its ability to reproduce a very neutral sound as it comes directly from the recording console, without the intervention of digital sound processing.

  • Our Flagship DAC is a continuation of the theme which began with the Quad. With the Metrum Octave we doubled the dacs over and above the Quad using a total of 8 high speed dac chip-sets, 4 per channel. The result was much improved resolution with lower noise and distortion.”

  • “For the Hex we have doubled the boards and improved upon these attributes even further. The Hex uses 16 of these industrial high speed dac-chipsets, 8 per channel and operates in full differential mode. In addition it has 1 x BNC coaxial, 1x RCA coaxial, 2 x optical, an optional USB and AES/EBU input.”

    Due to fully galvanic separation of these DAC boards, three toroidal transformers are used to feed the DAC boards, control logic and USB. Consequently, frequency response, distortion and channel separation are all improved.”As a result the dac sounds very close to real analogue.

    Input sample rates possibilities extend further than the Octave too. All inputs will handle up to 24/192, except toslink which is held to a maximum of 24/96. Outputs are both balanced and single ended.
