Can you explain about this spitter ?

 

Hi! R1200CL, 

 

This is a transformer type 10M Signal Distributor made from Cybershaft in Japan. This small device can be use on all Giesemann Clock for 50ohm version only, it can output two 10M BNC in the same time with one input. Output 1 can be input to DAC with 10M Master In and Output 2 can be input to UpTone EtherREGEN. 

 

 

The Project ClayX WoodMAT is sold separately under Project AudiophileMAT Collection.

One set will included 4 blocks of very rare purple sandalwood and WoodMAT

 

The AudiophileMAT Black Mountain Series 1 is a very fine choice for small device like DAC, Switch. 

 

The Black Ceramic Beads version

 

 

Best Regards,

So you have different balls available ? I like the Ceramic option. That should be better than metal.

Hi! R1200CL.

 

We have two option to choose, one is Steel and one is Ceramic which is much better.

Is your clocks AT cut or SC cut ?

Hello! R1200CL.

 

All Giesemann is SC cut. This is refers to stress compensated (SC) cut crystal resonators

 

Thanks and have a nice day.

Hi! R1200CL, 

 

That is correct, the best seller Queen Square Wave 75 ohm special edition is tailor made and optimised to work with EtherREGEN. 

 

Thanks for your question.

AfterDark. 

Sorry for asking again.
 

Is the Queen Square Wave 75 ohm special edition actual a native 75 ohm clock ?

Or is it the adapter that makes it 75 ohm ? 

 

Can you clarify if it’s a 50 ohm or 75 ohm cable that comes with Queen Square Wave 75 ohm special edition. (You said before the cable comes in both versions). 

 

If one chose any other audiophile version, they’re all 50 ohm sine clocks that is offered with adapters from 50 to 75 ohm ? And in addition a 50 ohm one meter cable ?

Does it offer isolation ?

Can it be used with the 50 to 75 ohm adapter ?

• Yes, Giesemann Clock version Square Wave Special Edition is native 75ohm Clock

Or is it the adapter that makes it 75 ohm ?  

• No adapter is required to make it 75ohm

Can you clarify if it’s a 50 ohm or 75 ohm cable that comes with Queen Square Wave 75 ohm special edition. (You said before the cable comes in both versions). 

• Queen Square Wave 75ohm special edition will come with 75ohm cable made by Belden in 1 meter.
• The Sine Wave 50ohm version will come with 50ohm cable made by Huber + Suhner in 1 meter.

If one chose any other audiophile version, they’re all 50 ohm sine clocks that is offered with adapters from 50 to 75 ohm ? And in addition a 50 ohm one meter cable ? 

• For group buy at Audiophilestyle.com edition. All 50ohm Sine Wave Clock will offer free Cybershaft adapters from 50 to 75ohm.
• The group buy will offer free 1m Huber + Suhner 50ohm BNC cable

Hi! R1200CL,

 

This is transformer type distributor is excellent choice for output two devices. Since it is a transformer type, it can be distributed with almost no deterioration in clock quality. 

 

It can be used with the 50 to 75ohm adapter. 

 

For example, the distributor will plug in directly to Giesemann Clock and two cable can outputs 10M signal in 50ohm.

Then, the one cable in 50ohm can be plug in to 50 to 75 ohm adapter to connect EtherREGEN in 75ohm.

The last cable can be connect to your DAC/DDC which accept 10M Master In in 50ohm. 

 

***Please noted this adaptor only can use in 50ohm version of Giesemann Clock***

.....and of cause no adapter (75 to 50 ohm) with the Queen Square Wave 75 ohm special edition ?

People have tested 2 Belden 75 ohm cables. What Belden Cable is offered ?

Hi! R1200CL,

 

For 75ohm version BNC Clock cable, we are using the BELDEN 1865A.

my square wave received with a "certificate"

1hz: -104
10 Hz: -135
I don't know if that can help.

No, that’s another question, how is those measurements actually done, as you can’t connect to the BNC as you would do with a sine.

Hi! R1200CL, 

 

When perform measurement on square wave OCXO, it requires to convert from Square Wave to Sine Save to measure the phase noise. Therefore, the measuring result is a little bit conservative vs real performance when connect to EtherREGEN. 

 

Thanks and have a nice day.
