Connecting a 110 ohm LTC signal to the card

A Linear Timecode (LTC) signal is an audio signal encoded with SMPTE timecode data with a
preferred range 1 to 2V used to support time synchronization between devices. The SSP-
3801 card provides one unbalanced input with a 75 ohm linear timecode BNC connector
(

LTC In

) which can be connected to an LTC generator to provide the card with a time code

source.

If your LTC generator generates a 110 ohm LTC signal, you must use a balun that converts a
110 ohm XLR connector to a 75 ohm BNC connector to connect your LTC generator to the
card.
