1. INTRODUCTION
Thank you for choosing DENAFRIPS products!
PONTUS is DENAFRIPS premium DAC. To achieve the highest possible sound quality within
the price constraint, DENAFRIPS adopted a lot of the technology and architecture can be
found in the flagship DAC, the TERMINATOR. Yes, that’s right, Pontus is designed about the
similar architecture of the Terminator. Pontus is further enhanced in the power supply
design compared to Ares. The power supply is encapsulated in a 1.5mm thick metal alloy,
equipped with dual o-core transformers, completely isolated super linear regulator power
supply for digital and analogue section, ensuring low noise, high availability power supply to
the DAC.
The Pontus employs true balance R-2R DAC design. Each channel is equipped with
independent high-speed FPGA to control the decoding by 4 sets of 0.01% R-2R network. This
design has very small linear error, high decoding speed, low digital noise, not only to ensure
that the audio signal is low distortion, but also to ensure a very low background music noise;
allow listener to enjoy the true music with dark background.
We are confident Pontus sound quality far exceed its modest price tag.
