I suspect that I may be asking a stupid question but here goes. I have had the above gadget for some years but always wondered if there was any benefit of matching another Dac with it by using the 75 Ohm Word Clock input to receive the signal from the Dac.
Is this deigned to match the clock in the Dac to the Behringer clock for better transmission?

Word Clock was an old way whereby studios could synchronize the clocking in all their digital audio equipment. The studio had a master Word Clock generator box. IIRC, the word clock frequency is the same as the LRCK frequency or the sample rate frequency; something like that. Then a PLL was used to generate a master clock signal inside each digital audio device, where the PLL was synced to the incoming word clock frequency. The downside of that approach was that PLLs could not achieve jitter (phase noise) levels as low as a good crystal clock can.
Thus, as ASRC (asynchronous sample rate converter) circuits got good enough, each digital device could use its own crystal master clock (instead of using a PLL), and then the digital device could use ASRC to convert an incoming digital audio stream to be synchronous with the local crystal master clock. Overall that new system without Word Clock tended to work and sound better.

Don't know. Haven't read the user manual for that unit. Haven't looked at a schematic or service manual either.
There are some gems in the Behringer cheap 1U rackmount stuff. Many years ago I had some ADA8000 & ADA8200 and found out some great info from someone who documented an upgrade to use torroidal transformer, linear PSU etc.
These were built cheap, so the included PSU is absolutely miserable, expect to replace it right away. Many times i bought some of these "broken" but really just the PSU was unable to put out the needed voltage anymore.
The PCB are usually clones from much higher end devices, or actually well designed, just constrained by really cheap PSU and wiring.
But, I think adding another device just to manage clock is not going to be beneficial, it's just another (noisy) device in the signal chain as is.
