8 - Synchronization with other DTRS unitsTASCAM DA-78HR 513 Press the CHASE key on all of the slave DTRSunits. The indicator will flash.4 Press FORMAT/Fs twice within five seconds, oneach of the DTRS units (master and all slaves)so all machines are ready to start formatting.If you press the CLEAR key while the FORMATindicator is lit steadily, you will cancel the for-mat operation.5 Select the same sampling rate (48 kHz or44.1 kHz) on each DTRS unit.Any slave DTRS unit which has a differentsampling frequency selected from that selectedon the master will display an error message.6 Press and hold PLAY and press RECORD onthe master. All slave units’ CHASE indicatorswill light steadily, and the tapes will start to beformatted in synchronization.8.5.1 Recording while formattingAs with a single-machine format (5.1.4, “Recordingwhile formatting”), it is possible to record while for-matting on multiple machines.You may want to use this feature when making a livemulti-machine recording, and there has not been timeto format all the tapes in advance of the performance.Remember that you should let the tapes run to theend—you should not halt the formatting/recordingprocess part of the way through the tape.8.6 Individual clock modeThere are some circumstances where it may be nec-essary to use independent reference clocks on a chainof DTRS units when TC time mode (see 9.2, “Tapetimecode mode”) is selected.There are two settings, AUTO and INDVID (individ-ual). AUTO is the default, and the unit behaves as fol-lows when this is selected.In individual mode, the unit behaves as follows:1 Press the SHIFT key so that the SHIFT indicatoris flashing, and press the MENU key, until thecounter shows SYSTEM-- (SYSTEM--).2 Press the SUB MENU key until the displaybriefly shows CLOk. MODE (CLOK MODE) andthen changes to the current setting.3 Use the s and t keys to change between theAUTO (AUTO) and INDViD (INDVID) modes.8.7 Error messagesThese error messages refer to DTRSsynchronization:E. DIO (E DIO)—appears if the digital cable is notconnected. Re-connect the correct cable to theDIGITAL I/O connector.E. CLOC (E CLOC)—appears when the sync cable isnot connected, the master has been turned off, or themaster’s sampling frequency is different from that ofthe slave unit’s. Recheck these parameters.If either of these messages appears, correct the faultto return to normal operation.Slave unit’sTime Mode Master DA-78HR Slave DA-78HR unitsABS All clock sources DTRS syncTCInternal InternalWord sync DTRS syncSlave unit’sTime Mode Master DA-78HR Slave DA-78HR unitsABSAll clock sourcesDTRS syncTC Internal, WORD orDIGITAL IN
