Antelope Audio OCX Master Clock - Manual (Page 5)

Rear Panel
Power Connection
This IES AC connection accepts an input of 95-245 VAC 50/60 Hz. As a result, the OCX
automatically accommodates a full range of voltages, allowing safe use in any country.
Atomic Clock In and Thru connectors
The Atomic Clock Input allows the OCX to operate with unprecedented accuracy. This BNC
input accepts the 10MHz clock signal found on many atomic clock devices. The OCX can
utilize this ultra precise timing reference at any of its supported sample rates.
The Atomic Clock Thru allows additional devices to slave to Atomic Clock received by the
OCX. This allows additional OCX units to be present in the studio, all utilizing the benefits
of atomic clock in perfect sync.
Word Clock outputs 1-6 The sample rate provided by these BNC outputs always
matches the sample rate indicated by the Frequency Display on the front panel.
For best results, WC cables should not exceed 20ft. (6m.) in length. Longer cable runs
result in increased jitter and other clock errors.
Word Clock outputs 7-8
The sample rate provided by these two outputs can match the sample rate of outputs 1-6 or
be changed to alternate sample rates by using the corresponding knobs on the front panel.
AES/EBU outputs
Provide clock in the AES/EBU format. AES/EBU is the best option in situations requiring
long cable runs. AES/EBU accommodates cable runs up to 300ft. (90m.).
S/PDIF outputs
RCA connections provide clock via Coaxial S/PDIF.
For best results, S/PDIF connections should not exceed 10ft. (3m.).
