Audio-GD - R28 2020 Upgrade
Upgrade your exisitng R28 model to latest R28 "jumperless" R2R dac!
R-28 (2020 version)
1, Dual transformers power supply separately.
2, The FPGA process data upgrade to parallel mode.
The IIS data is series transmit mode, every data must need one clock cycle to process or transmit, one frame data ( Include L and R data) must need 64 clock cycle to process or transmit, so the data has effect by the 64 clock cycles.
But the parallel data process and transmit mode only need one clock cycle can finish the one frame data process and transmit, that can avoid the effect of clock stability .
The IIS input (Include USB and HDMI-IIS) has recombine become dual 32bit parallel data once input , and the SPDIF input after decoder, has recombine become dual 24bit parallel data, and the DSD input has recombine become dual 64bit parallel data once input.
The parallel process and transmit mode can improve the sound quality on the transparency and detail but still analog.
3, Full new configuration clock manage design built in, improved on the clock timing.
4, DSD asynchronous clock technology has apply that improves the sound quality obviously.
5, DOP support from coaxial input .
4, The unit has two gain modes, the 12DB on low gain for drive the headphone which has over 95DB sensitivity, and 22DB on high gain cooperate with the strong power ability, enough to drive the HE6 which has around 85DB sensitivity headphones.
Menu Controlled System
All functions operable from front panel for user friendly experience. In total 7 different sound characteristics: 4 different algorithms in NOS mode and 3 types oversampling modes. (Jumper-less version!)
This upgrade includes:
- FPGA update to latest firmware (Improved soundquality)
- Programmable menu. No jumpers; all settings are available on front panel menu.
New "JUMPERLESS" design! Menu controlled settings
