GENx192 Studio Master Clock

Hardware and Connections

POWER:

 

  Connect the IEC connector side of the supplied AC cord to the receptacle on the 

rear of the GENx192. Connect the other side of the AC cable to an AC power 

source that is of the correct voltage and frequency (100-240 VAC, 50-60 Hz). Use 

only the power cord and connector specified for the product and your operating 

locale.

INPUTS (optional):

 

  If the GENx192 is being used to distribute an existing clock source, connect 

that clock source to either the WORD CLOCK or AES input. Both inputs may be 

connected simultaneously but only one input may be selected at a time using the 

SYNC SOURCE selection knob on the front panel.

WORD CLOCK:

 

 

  Using a 75Ω coaxial cable (RG-59 or better) terminated with male BNC 

connectors, connect one end to any of the eight GENx192 WORD 

CLOCK outputs, and the other end into your destination device’s word 

clock input. Repeat as necessary to connect additional devices.

AES CLOCK:

 

  Using a 110Ω shielded, twisted pair cable terminated with one male and one 

female XLR connector, connect the female end to any of the four GENx192 AES 

outputs and the male end into your destination device’s AES input. Repeat as 

necessary to connect additional devices.

 

NOTE :

   Be sure that the designated AES input of your destination device can be 

configured as an AES sync source for that device.

S/PDIF CLOCK:

 

 

  Using a 75Ω coaxial cable (RG-59 or better) terminated with male RCA connectors, 

connect one end to either GENx192 S/PDIF output and the other end into your 

destination device’s S/PDIF input.

 

NOTE 1:

   Many consumer and “pro-sumer” devices do not offer Word or AES clock inputs. 

However, of those devices, many do have S/PDIF digital audio inputs, such as the 

Digidesign 001 and 002 workstations. These devices typically allow the S/PDIF input to be 

a sync source while allowing concurrent audio throughput from both the S/PDIF and other 

ports (such as ADAT Optical). If your device fits this profile, the GENx192’s S/PDIF output 

will allow that device to finally sync to the outside world!

 

NOTE 3:

   There is no clock-only specification for S/PDIF digital audio, as there is within 

the AES specification. Therefore, the S/PDIF output of the GENx192 is simply an 

unbalanced, transformer-coupled copy of the AES outputs. Most S/PDIF inputs will 

accept the AES-formatted data, but compatilbility is not always guaranteed.
