Therefore, it is usually better to insulate the GND of each output for better noise resistance. Depending on the system you are using, the GND of each device may be firmly grounded.

In measuring equipment, 50Ω is common, but in audio equipment, the input impedance of the word clock is 75Ω, so the external 10MHz input is also 75Ω in many cases. Impedance matching is effective in preventing the generation of reflected waves, so it is best to match the impedance of the external clock input of your audio equipment.\u003cbr\u003eFor our clock products, the clock output impedance can be set to 75Ω \/ 50Ω according to the device you are using with a switch. (Registered utility model)\u003cbr\u003eEven if your audio equipment changes in the future, impedance matching of the external 10MHz clock can be reliably supported.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eOutput GND insulation \/ chassis GND selection function :\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe output GND potential can be switched between \"insulated from the chassis GND\" and \"housing GND\". If the output GND of this unit is grounded in common, when multiple devices are connected, the GND potential difference of each device will flow through the GND of the connection cable, causing noise called a GND loop. Therefore, it is usually better to insulate the GND of each output for better noise resistance. Depending on the system you are using, the GND of each device may be firmly grounded. If there is no GND potential difference between these devices, it may be better to have the output GND grounded to the chassis GND to obtain better results against noise.\u003cbr\u003eSince the environment of the audio system is various, you can choose the most suitable method according to your own environment.

If there is no GND potential difference between these devices, it may be better to have the output GND grounded to the chassis GND to obtain better results against noise.\u003cbr\u003eSince the environment of the audio system is various, you can choose the most suitable method according to your own environment.

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.

There have been about three cases where the OCXO itself failed, but in those cases, the output signal was lost and it was not possible to lock on the connected device, so it was immediately obvious. Unfortunately, there have been over a dozen cases where the oven monitor LED failed. This was counterproductive, as the monitor function itself, which is supposed to determine the failure, was the most common cause of failure.

In past cases with our products, there have been no cases where only the oven on the OCXO failed. There have been about three cases where the OCXO itself failed, but in those cases, the output signal was lost and it was not possible to lock on the connected device, so it was immediately obvious. Unfortunately, there have been over a dozen cases where the oven monitor LED failed. This was counterproductive, as the monitor function itself, which is supposed to determine the failure, was the most common cause of failure. Therefore, the oven monitor LED has been removed.\u003c\/p\u003e","brand":"Cybershaft","offers":[{"title":"OP23A Signature 4CH Silver \/ EXT DC \u0026 AC220V-240V  (AC cable not

In past cases with our products, there have been no cases where only the oven on the OCXO failed. There have been about three cases where the OCXO itself failed, but in those cases, the output signal was lost and it was not possible to lock on the connected device, so it was immediately obvious. Unfortunately, there have been over a dozen cases where the oven monitor LED failed. This was counterproductive, as the monitor function itself, which is supposed to determine the failure, was the most common cause of failure. Therefore, the oven monitor LED has been removed.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Cybershaft","offers":[{"title":"OP23A Signature 2CH Silver \/ I do not need LTPW03P.

Six LT3045s are configured in a parallel configuration to operate under the ultimate conditions. This two-stage power supply design thoroughly refines the power that passes through the primary power supply circuit in the secondary filter circuit.\u003cbr\u003eThe lead wires of the custom-made, large-scale R-core transformer used in this unit, which has extremely low magnetic flux leakage, use precision conductor \"102 SSC.\" The primary power supply is a proven linear power supply that employs SiC Schottky barrier diodes, large-capacity low-ESR capacitors, and OSCONs. 102SSC is also used for the internal wiring.\u003cbr\u003eThe output is equipped with two ITT XLR-4P connectors, allowing for future connection to expansion devices such as distributors. (Two units cannot be connected to an OCXO product simultaneously.)\u003cbr\u003eThree lengths of 14-gauge, extra-thick oxygen-free copper cable are available. Keep this unit as far away from the OCXO as possible.\u003cbr\u003eThe internal circuit board uses a 70μm thick copper foil board, which is twice the usual thickness.\u003cbr\u003eYou can choose from two front panel designs: one with no acrylic panel on the front to match the design of 4\/6 output clock products, and one with an acrylic panel on the front to match the design of 2 output clock products.\u003cbr\u003eBacked by a two-year free repair warranty.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eUltra-low noise and ultra-high PSRR linear power supply :\u003c\/strong\u003e\u003cbr\u003eEquipped with a six-unit parallel circuit that maximizes the performance of the new generation linear regulator LT3045.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0349\/5310\/1452\/files\/ltpw03.jpg?v=1770220187\"\u003e\u003cbr\u003eThe primary power supply is followed by a two-stage power supply circuit featuring the ultra-high PSRR LT3045.

There have been about three cases where the OCXO itself failed, but in those cases, the output signal was lost and it was not possible to lock on the connected device, so it was immediately obvious. Unfortunately, there have been over a dozen cases where the oven monitor LED failed.

In past cases with our products, there have been no cases where only the oven on the OCXO failed. There have been about three cases where the OCXO itself failed, but in those cases, the output signal was lost and it was not possible to lock on the connected device, so it was immediately obvious. Unfortunately, there have been over a dozen cases where the oven monitor LED failed. This was counterproductive, as the monitor function itself, which is supposed to determine the failure, was the most common cause of failure. Therefore, the oven monitor LED has been removed.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Cybershaft","offers":[{"title":"OP19A Plus 2CH Silver \/ I do not need LTPW03P.

In past cases with our products, there have been no cases where only the oven on the OCXO failed. There have been about three cases where the OCXO itself failed, but in those cases, the output signal was lost and it was not possible to lock on the connected device, so it was immediately obvious. Unfortunately, there have been over a dozen cases where the oven monitor LED failed. This was counterproductive, as the monitor function itself, which is supposed to determine the failure, was the most common cause of failure. Therefore, the oven monitor LED has been removed.\u003c\/p\u003e","brand":"Cybershaft","offers":[{"title":"OP19A Plus 4CH Silver \/ EXT DC \u0026 AC220V-240V  (AC cable not

If the output GND of this unit is commonly grounded, when multiple devices are connected, the GND potential difference between each device flows through the GND of the connecting cable, causing noise known as a GND loop. Therefore, it is generally better to isolate the GND of each output for better noise reduction. Depending on your system, each device may be properly grounded to earth. In such cases where there is no GND potential difference between devices, grounding the output GND to the chassis GND may yield better noise reduction.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan\u003eAudio system environments vary, so you can choose the optimal method for your environment.
