ALESIS M20 REFERENCE MANUAL 1.06 15-5

TUTORIAL 2: MAKING DIGITAL BACKUPS

You can create safety copies of M20 tapes by copying all eight tracks to another M20 (or

ADAT-compatible machine) via the digital bus.

Alesis recommends creating a backup whenever you have irreplaceable material on tape.

Synchronizing two machines together via the 9-pin sync bus allows for making sample-

accurate copies, referred to the internal time code. This is preferred. Without sync, you can

simply start recording on the slave and play back from the master. This faithfully copies the

audio information, but in all likelihood there will be a timing offset between the two tapes.

Here’s the procedure for creating a backup tape.

Action You do... You see...

Synchronize the master and

slave

Connect a male/male, 9-pin D

master Sync Out and the slave

into the master, and a blank or

formatted tape into the slave

• To make a 20-bit backup, both machines must be Type II with tapes formatted in 20-bit mode.

• If the tape is unformatted, put the slave into Format mode (see Chapter 4). If the tape is partially

formatted, the slave tape needs to have its format extended (see section 4.5).

• For safety’s sake, write-protect the tape to be copied by breaking off (or sliding open) the tape’s

write protect tab.
