Using a PreRead Offset allows you to perform a simultaneous play and record
operation in a single disk channel, but without destroying the playback material as
with a standard “destructive” PreRead operation.
1. To change the PreRead Offset parameter:
ƒ
Type the desired PreRead Offset value into the numeric keypad and then...
ƒ
Press
PreRead Offset
The value may be set from 00.00 up to 2.00.00 (two minutes).

F3 PreRead Delay
This parameter is used to define the amount of external video/audio signal processing
delay that exists in the signal path from the Attaché output to the Attaché input. This
signal delay may be introduced by an external switcher, mixer, or other processing
devices (like keyers or effects machines). The PreRead Delay parameter
compensates for this external delay, and only takes effect only when the “PreRead”
record mode is selected with softkey
. A PreRead Delay value of 00.00 is
used when there is no external delay in the path from the Attaché output back to
input.
Type a value into the numeric keypad and then press softkey to set the
value, expressed in frames. The range of values permitted is from 0 to 5 frames.
1. To change the PreRead Delay parameter:
ƒ
Type the desired PreRead Delay value into the numeric keypad and then...
ƒ
Press
PreRead Delay
The value may be set from 0 Frames up to 5 Frames. If you enter a value greater
than 5 frames, then the maximum of 5 frames is taken.
