6.1A Normal Method (Time Code Accurate)
1. The two ADATs should be connected in the normal manner:
• Connect the SYNC OUT of the master to the SYNC IN of
the slave using an Alesis 9-pin sync cable.
• Connect the DIGITAL OUT of the slave to the DIGITAL
IN of the master using the fiber optic cable that came with your ADAT.
2. Put the original tape to be copied into the slave ("id 2") ADAT, which will be the
source.
3. Put a blank or preformatted new tape into the master ("id 1") ADAT, which will be
the target. (If the tape is blank, press Record Enable on all tracks of the master,
and then press FORMAT on the master).
4. Set the master ADAT's clock source to internal by holding SET LOCATE and
pressing DIGITAL IN until the display says "Int".
5. Press the DIGITAL IN switch on the master and slave machine. Both DIGITAL
IN LEDs should be lit.
6. Record enable all tracks on the master (target) ADAT. Make sure all tracks on
the slave are in SAFE mode (red LEDs not on or blinking).
7. Press PLAY and RECORD on the master ADAT.
8. Press STOP on the master after backing-up is complete.
The result is a new "clone" of the original master that will synchronize sample-
accurately as if it were the original.
It is also possible to make a "clone" from the master machine to the slave machine,
although this isn't the preferred method if the source tape has shown any signs of
deterioration. Simply connect the DIGITAL OUT of the master to the DIGITAL IN of
the slave, and press the Record Enable switches on the slave machine instead of the
master. Note: Even though the master machine is the source and may not have
anything plugged into its optical digital input, you still need to press Digital In on the
master and set its clock to internal (hold Set Locate and press Digital In so the
display reads "int"). The reason that the master's DIGITAL IN LED must be lit during
backup is so the master "knows" that it is making a digital transfer, and uses the
proper time settings for a digital transfer. This assures sample-accurate timing
precision.
If some of this is hard to remember, an explanation of how Digital In affects
synchronization may help. Consider a situation where you have two ADATs, and
want to back up the slave ADAT’s tape to the master ADAT. So, you connect the
