520DARS-W
Unbalanced AES Word Clock Extractor and Distribution Amplifier
The 520DARS-W provides a compact method extracting word clock from your AES digital audio reference signals. The 520DARS-W features one auto-equalized input with 4 word clock outputs and 5 reclocked AES audio outputs.
The 520DARS-W can be used in conjunction with the 5600MSC Master Clock/SPG system.
The 520DARS-W is housed in the 3RU 500FR 
frame that will hold up to 16 modules.
