Talk Back. A DA7 feature that allows the person operating the mixer to talk
to the studio from the control room.
TDIF/Teac Digital Interface Format. An 8-channel digital audio interface for
use with DA-88 type digital multitrack recorders (DTRS).
timecode. An eight-digit number that identifies a specific frame in a tape. It
is also an electronic timing signal, based on the 24-hour clock, that is
recorded along the length of the tape and provides markers for locating
specific program material. There are two types of timecode, non-drop
frame and drop frame. Non-drop frame timecode is based on 30 fames of
video per second. Drop frame timecode is based on 29.97 frames of video
per second. For short amounts of time, this discrepancy is inconsequential.
For longer periods of time, however, it is important. One hour of non-
drop frame timecode will be 108 frames longer than one hour of real
time. See also non-drop frame timecode and drop frame timecode.
undo. Cancels the last operation. You cannot undo a save.
VU meter Volume Units. A special type of volt meter designed and
calibrated to follow perceived audio volume. 0 VU equals +4 dBu.
window. A rectangle frame of data on the display. It lets you “see” and work
with programs, applications, or functions. Several windows can be open
at one time.
write. To record data on a medium.
Wordclock. A reference syncronization pulse used in digital audio
equipment to eliminate timing errors. The use of a dedicated wordclock
line is more reliable. It is often used in more complex systems and
multitrack recording to ensure proper syncronization.
XLR. A three pin audio connector.
zoom. Enlarging or reducing the size of an image or a display.
