NOTE:
The transmitter does not continue to keep timecode when it is powered down. Every time the unit’s
power is cycled, it will be necessary to jam its internal-clock.
Manually Jamming TC with a Cable
Timecode can be jammed into the transmitter by connecting the timecode source to the microphone input or
using the stereo adapter. When timecode is connected, it takes the transmitter approximately three (3) seconds
to recognize the TC input. The screen display
TIME CODE
followed shortly by
JAMMED
when it is
recognized. When the word
JAMMED
disappears, the timecode input source can be disconnected and normal
operation can be resumed.
When using the mic input connector with a mic-level source, the audio level of the timecode needs to be between
-30 and -10 dBFS on the transmitter’s meter. Any level above -10 may cause clipping, which will prevent proper
reading of timecode.
When using the mic input connector with a line-level source, a line-level to mic-level cable should be used to
attenuate the timecode signal out of a generator to the correct audio level.
When using the line-level input connector (STA100 or TCA100) with a line-level source, a non-attenuating cable
should be used.
