6 – Hookup—Synchronization and control connections48 TASCAM DM-24 Reference ManualWord sync clock connectionsNOTEIn every digital audio setup, there must be one, andonly one, word sync source. If there is more than onesource in a system, there is a risk of causing damage tothe monitoring system (and your hearing).The DM-24 can act as either a word sync clock mas-ter or as a slave.In the case of the DM-24 acting as a master for thesystem, make sure that the switch by the BNC wordsync connectors is in the center position (75-ohm INtermination is OFF, and the DM-24 generates theword sync signal from the OUT terminal).In the case of the DM-24 being a word sync clockslave, it is possible for the DM-24 to either retransmitthe word sync to other units, or to act as the last unitin the word sync chain.When retransmitting the sync, set the switch to theleft position (75-ohm IN termination is OFF and theOFF/THRU setting is set to THRU).If the DM-24 is the last unit in the word sync chain,the switch should be in the right position (75-ohm INtermination is ON).All input and output is at TTL level.Select the word sync source using the CLOCK screenin the DIGITAL section (“CLOCK settings” onpage 24).NOTEIt is not recommended that any ADAT unit is set up tobe a word clock slave.MIDI connectionsMake these connections following the usual MIDIstandardsSee “MIDI” on page 95 for details of how the DM-24uses MIDI.Also see “SYNC/TC” on page 23 for further detailsof MTC operation.SMPTE/EBU timecode connectionsSMPTE/EBU analog timecode is received at theTIME CODE IN connector on the rear panelThe timecode is needed when using the automatedmix functions.Note that the DM-24 does not output analog time-code, but can output MTC for use by other units.See “SYNC/TC” on page 23 for details of setting upthe DM-24 to use the timecode.Meter unitThe optional MU-24/DM meter unit may be con-nected to the TO METER connector.Consult the documentation with the meter unit forfull details of installation and using the meters withthe DM-24.P2 connectionsDevices which implement the P2 protocol can becontrolled by the DM-24.See “Machine Control/Location” on page 80 for fulldetails of control of other devices using the DM-24.
