TIME CODE MENU 

 

Time Code Frame Rate Set 

 

 

 

 

The time code frame rate menu is where the time code frame rate is set.  

The TRX745 will lock to and record all standard time code frame rates. 

 

23.98, 24, 25, 29.97DF, 29.97DF, 30 DF, 30 NDF 

 

Time Code Source Select 

 

 

 

 

The time code source menu selects how the transmitter will receive its time code. 

 

 

ZAXNET (RF)

 - The TRX745 will receive time code via ZaxNet from a Nomad, a QRX235, IFB100/200, 

TRX900CL or another TRX transmitter or a ZFR recorder that is transmitting ZaxNet time code. 

 

 

AUDIO INPUT 

- The TRX745, with a proper cable, will receive time code via the microphone input.

 

When time code is connected, it takes the TRX745 approximately three seconds to recognize the TC. The 

screen will display TIME CODE followed by JAM when it is recognized.  Please note that when using the 

microphone input connector, the audio level of the time code signal needs to be between -30 and -10 dBFS 

on the unit’s meter. Any level above -10 may cause clipping, which will prevent proper reading of time code. 

 

TC Jam Mode Select 

 

 

 

 

This menu controls if the TRX745 will go into record when it receives a record run time code. 

 

AUTO-JAM NORMAL 

- The TRX745 will continuously jam time code via ZaxNet and will go into record when 

receiving a record command via ZaxNet or if the unit is put into record manually by pressing the CARD and 

INC keys simultaneously. 

 

AUTO-LOAD REC RUN 

- In Auto-Load mode the TRX745 will go into record when it detects rolling time code, 

and will stop when the time code stops. If time code is lost because the IFB signal is too weak the unit will 

not stop but will continue in whatever state it was in until the time code signal is restored.
