Saving To Tape; Reading From Tape; Defaults - Alesis AI-2 Reference Manual

5.5 SAVING TO TAPE

The AI-2 is equipped to save information to the ADAT tape data
header. The AI-2 will transmit cue start times, tape start times,
pitch information and ADAT operational status such as cross fade
time, all safe status and auto input status over the ADAT sync port
to the ADAT machines. Press the front panel SAVE key then the
STORE key to confirm the save command. This facility permits
vital session data, required for synchronization, to be recalled when
a tape is used at a later date.

5.6 READING FROM TAPE

The AI-2 is designed to read information from the ADAT tape data
header. When a tape is put into the master machine the AI-2
automatically prompts you to read the data from tape. The AI-2
reads all the ADAT header information, even though it only requires
a small amount of the information. All the data is read, so that
subsequent tape save operations can restore everything to tape
without loss. The AI-2 specifically uses the cue start time and tape
start time information. This information is used to calculate the
ADAT offset which is required for synchronization.
5.7 AI-2 DEFAULTS
The AI-2 has a comprehensive and intelligent default configuration
system that is designed to automatically switch reference and code
type based on the type of controller detected. This system simpli-
fies standard configurations for normal operation while still
permitting the user to set up the AI-2 for special or unusual
applications.
The default control type is auto, this causes the AI-2 to scan the
control inputs for a connected control device. The AI-2 speed
reference is then set depending on the type of controller detected.
If a SONY editor is detected the reference is set to external video
and the code rate and type is then determined by the video sync
signal, 29.97 Hz/30 for NTSC and 25 Hz/25 for PAL.
If a TimeLine Lynx-2 or Micro Lynx is detected the speed reference
is set to Lynx and the code rate and type determined from system
information transmitted by the synchronizer to the AI-2.
If no controller is detected then the AI-2 switches to time code
chase mode and the reference is set to reader in. The default code
rate and type is determined by configuration dip switch one, if off, to
