Dedicated hardware units are built inside a FPGA-chip to form together a powerful and custom front-end to the dac chips. This include digital receivers sampling input signals at 500 MHz , the clock system able to reduce timing errors to sub-picosecond level, the powerful digital filter made with 15 DSPs, the user interface.
Femtovox clock system
(2 x AK4396) is a perfect complement to the digital input stage. Each dac chip is processing one channel in fully balanced mode which leads to better analog performance and noise rejection.
True balanced, zero-feedback class A output stage / headphone amplifier section will drive without problems from low to high impedance headphones.
All power supplies inside are linear type. There are a total of 11 linear stabiliser IC’s, 8 of them are low noise. The total filtering capacity exceeds 50.000 uF. The power supply is serviced by 2 separate toroidal transformers.
The Black Dragon can be updated in the field by easily playing a special update track via the USB input. Any firmware updates will be available under the download section.
