Nagra QSIP is an external accessory for Nagra IV-S TC. It complements the QSLS in order to control device playback, by comparing SMPTE Timecode which is read from tape with TC delivered by internal generator. The QSIP, set between Nagra and QSLS, converts read TC signal into pilot signal for the QSLS and, conversely, converts compensation signal delivered by the QSLS into a signal compatible with SMPTE reading boards of the Nagra IV-S TC. Here again, one will not forget to screw on the QSLS the crystal jumper plug; if not so, sync control is inoperative.
