1. INTRODUCTION
Thank you for choosing DENAFRIPS products! You have made the right choice to purchase
the company’s FLAGSHIP DAC! Congratulation!
The Terminator is DENAFRIPS' flagship DAC. Being a flagship, the Terminator is filled with
our years of R&D achievement in it. State of the art fourth generation discrete resistor 26Bit
R-2R for PCM decoding, 6Bit DSD hardware decoding with 32 steps FIR filters, a total
breakthrough of the traditional integrated chip constraints.
Dedicated encapsulated power supply section within the same chassis is equipped with Dual
Type-O Transformers, Ultra-Low ESR Reservoir Capacitors, and WALT Jung Super Regulators
and multi-stages super linear power supply to power up the DAC.
The DAC core conversion module R-2R is constructed with 0.005% high precision, 10ppm
low thermal effect precision resistors. Each channel uses more than 500pcs of these
precision resistors, or 1000pcs for two channels, it's 4 times more than the other typical R-
2R DAC. These achieve a truly astonishing low distortion, full balanced design. CRYSTEK
FEMTO clocks are used with FIFO Adaptive Buffer Technology to ensure the DAC clock is less
dependent to the input source.
It will be the Reference Master Class DAC of DENAFRIPS for the next 10 years.
