with a 0 dB offset and the fader will not move. When the fader is moved
from 0 dB, an offset equivalent to the amount of the move will be applied
to the Read Mix data and the net result will be heard.
On the D950 desk, the amount of the offset will be indicated in the Null
display and an arrow illuminates to indicate which way the fader must be
moved to match the Trim Replay value.
On the Vista desk, the offset is displayed by a pink bar (replay value) and a
gray bar (current value).
When a recorded Trim is played back with TRIM enabled, the fader will
move to indicate the Trim offset from 0 dB. If the value of the Trim Re-
play Data is recorded at –3 dB and then moves to –5 dB, the fader will
move
–3 dB and then to –5 dB at the appropriate time. The underlying Read Mix
data will be heard with the Trim offset applied. The Trim Replay Data may
be updated using TRIM RECORD techniques, thus allowing Trims to be
modified.
It should be noted that faders in TRIM do not follow the WYSIWYH
(What You See is What You Hear) paradigm. The recorded moves plus
Trim offsets will be heard, but only the Trim Replay values will be shown
by the fader.
Encoders: Any time an encoder is placed in TRIM, the null point will be 0 dB and the
encoder will "auto-null" to this value. Since there is no Trim Replay Data
for encoders, the null value can show only the offset of Read Mix values
from 0 dB. The null point for encoders is always a 0 dB offset from the
Read Mix value.
Whenever an encoder is put in TRIM, a 0 dB offset will be used. When a
recorded Trim is played back with TRIM enabled, the encoder will move
to indicate the Trim offset from 0 dB. As the pass is played, the changes in
the Read Mix values will be heard with a 0 dB offset and the encoder will
not move. When the encoder is moved from 0 dB, an offset equivalent to
the amount of the move will be applied to the Read Mix data and the net
result will be heard.
On the D950 desk, an arrow will illuminate to indicate which way the en-
coder must be moved to match the Read Mix value.
On the Vista desk, the pink-colored bar or dot (replay value) is used to
match the current value to the replay value
Record Off:
• TRIM ENABLE: The control is armed to go into TRIM RECORD.
Faders move to their Trim Replay values and both the Read Mix Data
and Trim Replay Data are replayed. The Read Mix values plus the Trim
offset will be heard. Any changes made to the Trim value (+/- from the
nominal Trim Replay value), will offset the Trim Replay value by that
amount. The first time TRIM ENABLE is used, faders will display a
nominal Trim value of 0 dB. Since the default offset value is 0 dB, the
Read Mix Data will be heard unaltered if the control is not moved.
While Read Mix data will be heard, it will not be indicated by the
fader's position.
Encoders display a nominal Trim value. The nominal value will vary
depending on the control (i.e. 0 dB for levels/gains, center for stereo
panner, etc.). Read Mix Data (Written changes plus any previous
