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

All Zaxcom mixer/recorders recorders, digital recording wireless transmitters, ZFR miniature recorders, ERX receivers, QRX w/QIFB, and URX receivers feature fully functional timecode readers and generators.

The timecode reader in each of these units allows it to receive external timecode that the unit will lock to. Zaxcom mixer/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 takes over and generates its own frame accurate timecode. The timecode generator in all Zaxcom products (with the exception of the ERX) are very stable and use TCXO temperature compensated crystal oscillators giving a clock accuracy of 1.54 PPM, which equates to 1 frame out in 6 hours. In the case of the ERX, a TCXO chip is not necessary since it is constantly updating its timecode from the ZaxNet source. All products can read and generate all standard SMPTE timecode frame-rates: 23.98, 24, 25, 29.97NDF, 29.97DF, 30NDF, 30DF.
