•MIDI IN/OUT — These standard MIDI connectors (female 5-pin DIN) can be used to send or receive MIDI Time Code (MTC) and MIDI Machine Control (MMC) when connecting to equipment with transport controls and a position display.

•ADAT SYNC OUT — This 9-pin D-subminature connector connects to the SYNC IN connector on an ADAT multitrack recorder when the SDR24/96 is providing the master sample clock. Use male-to-male 9-pin D-sub (DB9) cable.

•ADAT SYNC IN — This 9-pin D-subminature connector connects to the SYNC OUT connector on an ADAT multitrack recorder when the SDR24/96 is the slave. Use male-to-male 9-pin D-sub (DB9) cable.

Whenever digital audio connections are made between devices, the sample clock of every device must run at exactly the same rate. This is usually accomplished by selecting one device as the “master” clock source and distributing its word clock signal to all the “slave” devices in the system. The master is configured to run from its internal clock, and the slaves from external word clock. Some digital interfaces are self-clocking (such as the AES input on many DAT machines) and do not require a separate word clock connection. Others simply cannot be configured as slaves. The master/slave designation must be correctly made for each device to avoid the clicks and pops associated with asynchronous clocks.

Generally it doesn’t matter which device in a system serves as the word clock master. For example, if your SDR24/96 Inputs and Outputs are connected to the Tape Inputs and Outputs of a Mackie Digital 8•Bus console using ADAT optical, either the SDR24/96 or D8B can be the word clock master. (Note: The D8B must have the Apogee Word Clock Card installed for this application.)
