The DIF-AT is essential for interfacing Roland RMDB2 compatible equipment with ADAT. Below is a summary of the steps necessary for exchanging or recording eight channels of audio digitally to ADAT via the DIF-AT:

1. Insert a tape into the ADAT.
   NOTE: The ADAT tape must be formatted at 44.1 kHz to be compatible with Roland RMDB2-compatible equipment.
2. Make the connections for the RMDB2-compatible devices. For information about settings, refer to to the documentation for the RMBD2-compatible equipment (Roland VM-3100Pro,
   VM-7200; etc.)
3. Press [DIGITAL IN] on the ADAT. The LED will light. All eight channels will be received via
   the ADAT’s fiber optic connection.
   NOTE: The analog inputs will be ignored on the ADAT when it is set to record digitally.
4. Press [TRACK ENABLE] for the desired track. The track’s RECORD and INPUT Indicators flash
   and you can monitor the audio signals from the RMDB2-compatible device with the ADAT.
5. Press and hold [RECORD], then press [PLAY] to start recording on the ADAT.
