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 the product, long-term school proofreading, proofreading, and qualitative 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 KAMET Corp is placed on top of OCXO,  the outer layer is covered with 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 magnetic coverage.
  • Advanced instrument Symmetricom 5120A calibrated surveying characteristics. Passing through the clock, the original export-like phase, the noise, the noise, the difference, and the define the grade of the clock. 
  • Audio Note Silver Solder
  • Duelund AC0.4 Silver Premium Audio Cable (Silver in Cotton / Oil impregnated) (Handmade in Denmark)
  • 2 years warranty 
  • Optional external LPS power supply


Output GND insulation / shell GND selection function

  • The output GND potential can be switched between "Isolated from the housing GND" or "Shell GND". If the GND output from this unit is grounded together, when multiple devices are connected, the GND potential difference of each device will flow through the GND of the connecting cable, which will cause noise called GND loop.
  • Therefore, it is usually best to isolate the GND of each output from the noise output. Depending on the system used, the GND of each device may be properly grounded. If there is no such GND potential difference between each device, grounding the output GND to the chassis GND may obtain better noise effects.
  • Since the environment of the audio system is different, you can choose the most suitable method according to your environment. The bottom plate of this machine is equipped with the GND terminal of the shell.

External LPS power supply
This device is designed to operate only with external DC power. Make sure to prepare an external DC power supply. We recommend using our dedicated AfterDark. power supply, but if the specifications match, you can use your favorite linear power supply.

  • The external DC specification is 5V/ 12V 1A. 
  • The external DC plug standard is 2.1mm / 5.5mm. 

Ultimate OP 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 the phase noise characteristics and short-term stability (Allen dispersion) that can be further checked
OP selection value of MA series

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 audio clock, we are conducting a comprehensive evaluation of phase noise characteristics and short-term stability (Allen dispersion) for a more detailed inspection.


It is impossible to evaluate the product only by measuring the output characteristics of the built-in OCXO unit. The measured value of our calibration is not directly output by the OCXO unit, but measured from the output terminal of this product, in order to evaluate all performance including the buffer circuit.


Choose a base value
Phase noise: -119 to -113 dBc / Hz or lower at 1 Hz offset (OP distinction) -137 dBc / Hz or lower at 10 Hz offset (total)

[Emperor Giesemann] Phase Noise -120dBc at 1 Hz / -143dBc at 10 Hz

[Emperor Triple Crown] Phase Noise -113dBc at 1 Hz / -143 dBc at 10 Hz


Allan variance short-term stability reference value

[Emperor Giesemann] TAU = 1sec 2.38E-13或更短(0.00023ppb / s)
[Emperor Triple Crown] TAU = 1sec 3.8E-13 or less(0.00038ppb / s)
[Emperor Double Crown] TAU = 1sec 4.2E-13 or less(0.00042ppb / s)
[Emperor Crown] TAU = 1sec 4.6E-13 or less(0.00046ppb / s)
[Emperor Crown Singature] TAU = 1sec 5.1E-13 or less(0.00051ppb / s)
[KING] TAU = 1sec 5.6E-13 or less(0.00056ppb / s)

The above values ​​are not standard catalog values ​​(typical values), but guaranteed values, which are measured separately, so the product quality is constant. There is no so-called "decay".
