AC Power Inlet
- This 3 pin IEC jack accepts 120VAC @ 50 or 60HZ. The unit is internally
reconfigurable for 240VAC operation.
Word Clock Input -
This BNC jack accepts a standard TTL level word clock input. The in-
put is 75 ohm terminated and ground referenced. The input signal is well conditioned and
doesn’t really have a preference of shape or duty cycle.
Word Clock Output / Biphase input -
This BNC jack is configured before shipping as a
word clock output. This output will be a square wave at the sampling frequency selected. The
output impedance is 75 ohms and will have a valid TTL level signal with a terminated line.
This jack can alternatively be configured as an S/Pdif input for use as a sync source in place of
the optical input. Email us for details on how to do that.
AES/EBU Outputs -
These XLR outputs are 110 ohm, transformer-coupled standard sources.
They will drive any reasonable amount of 110 ohm terminated cabling effectively. They are sin-
gle-wire outputs under all conditions.
Opt I/O and Analog Inputs / AES inputs-
These jacks are standard TOS connectors.
The optical input jack will accept a 2 channel S/Pdif optical stream for use as a sync source up
to 96k.
The optical output jack will output a 2 channel S/Pdif optical stream that mirrors any one port
on the AES output XLRs.
Analog inputs 1-8 are floating 2.8k inputs (except 5-8 in D/D PEP are 110 ohm). The analog
signals presented here pass to the input attenuators and then to the A/D converters. Analog
inputs 5-8 do not go “through” relays.
