Precautions when ordering 

Our recommended external DC power supply (LTPW01P) and DC cable for connection are sold separately from the main unit.
Please use the option set sale.
The AC power cable is not included in the set order with the external DC power supply "LTPW01P".
You can prepare the AC cable yourself or order an additional AC cable on another page.
We will ship your order approximately 14 days after your order is confirmed.

Product Overview:

This product is a master clock for high-end audio that combines the technology and experience of cyber shafts.
Equipped with ultra-high precision OCXO that emphasizes price, and by making it a 2- output, the price is kept down while having high performance. In addition to the external DC power supply, it is equipped with an ultra-low noise and ultra-high PSRR regulator circuit equipped with three next-generation linear regulator LT3045.
Designed with a luxurious cast front panel.
Ultra low phase noise -119dBc / Hz (@ offset 1Hz MA-OP19) is available from the grade.

Features:

This product uses a brand new OCXO, and a unit with outstanding stability is selected and mounted by long-term calibration.
In addition to the OCXO unit, a robust heat insulating case composed of a magnetic shield plate and a heat shield board is added to maintain an environment where the performance of OCXO can be maximized.
The front panel is combined with a transparent cast material with a thickness of 4 mm to enhance the design.
The bottom of the chassis is made of 2 mm thick aluminum material + 8.4 mm thick laminated iron material, and has a robust vibration damping structure with a total of 10.4 mm thick plate. In addition, a strong magnetic shield using a 5.2 mm thick laminated iron material is configured around the board.
Uses aluminum die-cast 3-point support feet that can be stable on any installation surface. It can be replaced with an optional spike insulator with a 4 mm screw.
The output can be set to an impedance of 50Ω or 75Ω. (Registered utility model)
The function to insulate the GND side of the clock output from the GND of the main unit is the best way to protect against external noise. In most cases, insulating the GND will provide a noise-free connection and good results.
You can set whether to connect the output GND potential to the main unit's GND or to isolate it. It can flexibly handle complicated GND processing that differs for each audio system. (Registered utility model)
The DC supplied from the external DC power supply regulates the LT3045 with ultra-low noise and ultra-high PSRR inside this unit with a three-unit structure under the best conditions. Very clean DC is supplied to OCXO.
For the internal substrate, a copper foil substrate with a thickness of 70 μm, which is twice the normal thickness, is used. The internal layout, which has been verified many times, is in the best condition.
Equipped with an LED monitor that allows the oven circuit to operate normally and control the OCXO unit temperature.
Strictly measure characteristics using a highly accurate calibrated measuring instrument. The clock quality is guaranteed by plotting the phase noise and allan Diviation in the output section for each unit.
It comes with a 2-year free repair warranty.

Output GND Insulation / Enclosure GND Selection Function:

Choose between two grounding configurations for the output GND: insulation from chassis GND or connection to housing GND. Using a common ground for the output GND can lead to ground loop noise, especially when multiple devices are interconnected. To combat this, it's typically preferable to insulate each output's GND. Yet, in some systems where devices have consistent grounding, grounding the output GND to the housing GND might yield superior noise resistance. Given the diverse audio environments, select the option best suited for yours. This device also includes a terminal for housing GND on its base plate.


External DC Power Supply:

This unit exclusively utilizes an external DC power source. Ensure you have an external DC power supply ready. While we vouch for our dedicated LTPW01 power supply, any linear power supply meeting our specifications will suffice. The required DC specifications range from 13.5V to 16V at 1A, with 14V being ideal. To maximize LT3045's potential, use a DC power supply with minimal noise, starting from 13.5V. For the plug, a standard 2.1 mm / 5.5 mm DC plug works, but for a secure connection, consider the screwable [RS product 487-820] plug. (RS products are globally available. [RS WORLD WIDE])

OCXO Characteristic Selection Value:

Our product features an OCXO unit, stabilized and calibrated over several months, ensuring optimal performance as an audio clock. We don't simply gauge the built-in OCXO unit's output characteristics. Our rigorous calibration measures from the product's output terminal, providing a holistic view, inclusive of the buffer circuit's performance.

* We have changed the previously announced reference value for each grade to the selection value actually used by us and released it. All products already sold are shipped with the OP selection values in this table.

OP grade guarantee card:

An "OP grade certificate" with hologram is always attached to each OP grade product.
A tamperproof sticker is attached in the center. A hologram is printed on the right edge. In addition, a hologram sheet with the serial number described in the option grade certificate will be attached to the OCXO unit inside the main unit. Please be sure to check when purchasing for second use.
