The development of Giesemann Custom OCXO By Audiophile - PROJECT ALPHA

[AfterDark.]

The development of Giesemann Custom OCXO By Audiophile - PROJECT ALPHA 

 

The Project Alpha is initiate by group of audiophiles who requires a high quality OCXO with build in LPS in one chassis. The BLACK edition is the first product we try to made with "Custom OCXO By Audiophile".

 

The PROJECT ALPHA will be the equipped with Emperor Signature SE+, a exterme edition which is hand selected in 2,000 pcs out of simpling when we measured the individual OCXO. They have special characteristic of Ultra Low Phase Noise and Allan Derivation measurements. This is the achievement of economical of scale after years of building OCXO 10M Master Clock for audiophiles.  

 

The goal of The PROJECT ALPHA

• Utilise the handcraft and technical skills with specialise in measurement to optimised the range of OCXO products for Audiophiles. 
• Made to order Audiophile product with great attention to details
• Every PROJECT ALPHA is unique and welcome personallize with wide range of special specifications. 
• The product is designed with sound tuning in mind,  we discover new ways of optimise sounding with group of Audiophiles and we perform test the new product in real listening room. 
• PROJECT ALPHA is an experience and place the first priority on customer interaction, so please feel free to contact us for any advice or consultation to optimise your audiophile system. 
• PROJECT ALPHA is a life style, we like to build and make Audiophiles smile with music. 
• We measure all the OCXO with individual plot graphs with measurement with Symmetricom 5125A, a promise to achieve ultra high performance for Audiophiles.

Features 

• The product uses the selected audio grade OCXO, and through long-term calibration to select and install equipment with excellent stability.
• OCXO that employs with qualitative measure equipment.
• OCXO is enclosed and covered with Dynamat Extreme Corporation (Made in USA) which is used to stabilize and minimize heat separation,  addition EMI material from KEMET EMI Shielding is placed on top of OCXO,  the outer layer is covered with real leather to isolate the heat factors for maximizing OCXO performance . 
• Black Alu material + Carbon Fiber material front and backplate, solid anti-vibration. In addition, due to the thickness used, 3mm / 6mm Carbon Fiber material material with plate can provide solid EMI/ magnetic coverage.
• Advanced instrument Symmetricom 5125A calibrated with plotted characteristics. The phase noise, and Allen Derivation defines different grades of the OCXO. 
• Hand made in Hong Kong 
• 2 years warranty 
• Internal R-Core LPS power supply included

 

 

 

 

 

The Giesemann Clock Module (GCM) is using pure copper screw with Carbon Fiber AudiophileMAT to minimise the vibration and EMI noise. 

 

The AfterDark. Black Modernize LPS will use the Special Edition of R-Core Transformer, this is customized and designed for audiophile.

 

 

The BLACK Edition is optimised for Audiophile in one chassis solution. 

 

Level selection value
The OCXO installed in the product can calibrate the products used in industrial equipment for a long time, and use equipment with good characteristics. In order to optimally select the audio clock, we comprehensively evaluate with Symmetricom Flagship 5125A to analysis the phase noise characteristics and short-term stability (Allen dispersion) that can be determinate the OCXO grading accordingly.

The OCXO installed in this product uses a stable OCXO unit that has been calibrated for several months. In order to make the best choice of OCXO. We are conducting a comprehensive evaluation of phase noise characteristics and short-term stability (Allen dispersion) during detailed inspection. 

The final product will final measured and fine tuned with Keysight 53220A with reference to Atomic Clock , GPSDO. 

 

 

Emperor Signature SE+ Phase Noise is certified with measurement at -142dBc /Hz at 10Hz offset 

 

  Allan Deviation is certified with measurement at 3.57 10E-13 at 1 sec

 

 

 

 

Quality of OCXO is determined by Phase Noise at 1Hz / at 10Hz
Phase noise: -119 to -113 dBc / Hz or lower at 1 Hz offset (Grades) -137 dBc / Hz or lower at 10 Hz offset

Quality of OCXO is determined by Phase Noise at 1Hz / at 10Hz
Phase noise: -119 to -113 dBc / Hz or lower at 1 Hz offset (Grades) -137 dBc / Hz or lower at 10 Hz offset
