8.4D SEARCH MASTER
This function (available only in the ID 1 master M20 in a system) accommodates situations
where you want to use jog on a machine that is not the master (e.g., to find a particular point
on the tape of a slave ADAT only). In this case, you don’t want the slave M20 to follow the
master, but instead, to act as a “temporary locate master” so all machines (including the ID 1
master) park where the designated search master machine parks after a jog or shuttle
operation. The default Search Master machine is ID1. Search Master status is not retained
when the power goes off.
To set which online M20 controls the parking address for all other M20s in a system:
1. Press and hold Search for 2 seconds to enter Search Master Edit mode. The display
shows “Search Master: n” (n = 1 — 8 or All).
2. While continuing to hold Search, use the numeric keypad buttons (1-8, 0) or Up/Down
buttons to select a search master (default is 1). Releasing the Search button exits the edit
mode without changing the Search mode status.
Selecting a machine other than ID 1 as a search master and activating Search mode (Jogging
or Shuttling) causes the display to indicate momentarily “Machine n Search Master” (n = 1 -
8) or “No Search Master” when All is selected. If you pause a search, ID 1 will query the
search master, update ID 1’s tape counter, and locate all connected machines to the position
of the designated search master.
When search master equals All, ID 1 will not send a locate command to the slaves. All decks
will remain parked after a search.
Releasing the Search button exits Search Master Edit mode, and the M20 reverts to the
display prior to selecting the Search Master.
Note: ID1 must remain online, and the user must observe the time code display when
actively jogging or shuttling because when a slave is the search master, the master’s
tape counter display will only reflect ID1’s tape position until Search mode is paused
and ID1 has located to the search master’s tape position.
