AfterDark. Giesemann Reference Superchromat Audio Reclocker PA3- Digital Signal Conditioner

A mini Digital Signal Conditioner produced by AfterDark. 

gives a significant improvement on sounding

designed based on Project ALPHA program 

with one well respected member in Audiophilestyle.

To honor that moment, we invite all 

Audiophiles to share the happyiness 

 with friends

The one-of-a-kind creation was designed especially for one serious audiophiles in to connect the AfterDark. Trifecta Extreme Giesemann Clock on the audiophile system. The device is made by two motherboards inside that were individually working and seperated in two layers on Carbon Fiber AudiophileMAT at 3mm and 1mm thickness for best isolation. These existing arrangement are reconstituted as parts to bring the whole system to another levels. 


The Giesemann Clock Sync Module (GCSM) will either accepts external inputs of 10M Reference Master Clock Signal or works with internal OCXO. Two versions would be made to orders. 


The Digital Signal Conditioner PA3 will re-clock by GCSM to provide the best USB to Digital signal to Audiophile DAC. The PA3 not only changes in the overall sounding but brings all micro details and extracted them in precise timing with lowest possible jitter.





Audio is very vulnerable to noise. There are many types of noise that can negatively affect audio quality, but the noise that has the biggest impact on computer streaming is EMI, RFI, and impulse noise .


The main role of Digital Signal Conditioner PA3 is to block EMI noise coming from the USB and power supply RFI noise that enters the digital signal path. The PA3 can be provide the isolation between the USB and DAC, re-clock the digital signals with repeect to 10M Reference Master Clock, provide the best signal to signal for multiplies of word clock for 44.1 kHz and 48.0 kHz on both PCM and DSD signal path. This Giesemann Clock Sync Modules (GCSM) will performs the generation of clock signal on each frequenies in  22.5792Mhz & 24.576Mhz. 


To ensure the maxmisation on sound optimisation, the GCSM will generate a delicated 12Mhz for USB chips to re-clock with the same 10M Master Clock. The result of sync of multiple devices with same reference clock will make the sounding much better in sound image and dynamic with lowest time jitter possible. 




Giesemann Reference Superchromat Audio Reclocker PA3 is a device that accepts USB input with Giesemann OCXO precision clocking  technology to remove RFI noise and impulse noise coming in from cables, and revive or reclocking the digital signal for Audiophiles system.


The performance will be further improved with high quality LPS with DC 5V.  


The advantage:


  • The density in the sound image is increased, the color of the sound is revived, the sound of the singer's breathing, and the lingering sound that lasts until the end improves the sense of space and air, and the tone becomes more vivid and dense, allowing for musical nuances even in digital. Your sensibilities will be revived, and your music will start to sound more musical.


  • The sound stage is much wider and opened up with 3D and improved focusing, quietness, clarity, purity, detail, and precision , while OCXO increase the precision and microdetail extraction with more refine backgrounds, the smoothness and microdynamics will be much better represented and created spatial region. 


  • All the digitial output will be sync and output at the sametime, this can make multiple DAC or recording devices to accept playback at once. 



The Audio Note Bi-Polar KENSAI Capacitor will be used for sound tuning 



Behind the minimise design of the Audio Reclocker PA3 is the internal components and parts is precision apply during the assembly process by soldering the chips with industrial graded signal cable to nearest 1mm, the process illustrating the hand craftsmanship that went into creating this entirely unique devices, which is highly skill intensive and cannot be made in today commercial standand procedure.
