Zaxcom – Timecode

Built-in timecode reader and generator

Timecode is a sequence of numeric codes generated at regular intervals and is used for synchronization, logging and identifying record material in film, video and audio production.

All Zaxcom mixer/recorder recorders, TRX recording transmitters, ZFR miniature recorders, ERX receivers and QRX receivers with QIFB option feature fully functional timecode readers and generators.

The timecode reader in each of these units will allow it receive external timecode that the unit will lock to. Zaxcom mixers/recorders and QRX receivers also allow you to enter in your own timecode manually.

After inputting, or locking to, an external timecode signal the timecode generator will now take over and generate it own frame accurate timecode. The timecode generator in all of Zaxcom products, with the exception of the ERX, are very stable and use TCXO temperature compensated crystal oscillators that give a clock accuracy of 1.54 PPM which equates to 1 frame out in 6 hours. In the case of the ERX an TCXO chip is not necessary since it is constantly updating its timecode from the source. All products can read and generate all standard SMPTE timecode frame-rates: 23.98, 24, 25, 29.97NDF, 29.97DF, 30NDF, 30DF.
