6-2-3 Performing Preread Editing
Video and digital audio signals already recorded on the
tape can be used as an edit source for insert editing.
This type of editing is called preread editing, as the
VTR uses preread heads to read signals in advance.
Signals that are read in advance can be sent to mixers
for mixing, then recorded to the original channels or
other digital audio channels.
The preread editing settings are performed with the
ALT/[F1] (PRE READ) buttons in the HOME menu.
For details on the settings, refer to “4-2-4 Preread Settings
(PREREAD)” on page 4-17.

Notes
• In preread editing, if an input video signal is used as
the reference signal for the output video signal,
oscillation may occur because of loop connections.
To avoid this, select the external reference signal for
preread editing by setting the item 005. SERVO/AV
REFERENCE select in the VTR SETUP menu to
external.
• When preread mode is selected, shifting of the VTR
to E-E mode is disabled in all operation modes to
prevent oscillation caused by loop connections. If
preread mode is deselected while a loop between the
input and output of the same channel exists, E-E
signals are output and oscillation occurs. To prevent
oscillation, do the procedure below to select PB mode
for both the video and digital audio channels before
the start of preread editing.
1 Press the ALT/[F1] (PRE READ) buttons in the
HOME menu and select video, audio, or a/v.
2 Make the required connections for preread editing.
3 Perform preread editing after selecting the insert
editing mode.
4 After preread editing, undo all the connections
used for the preread editing.
5 Press the ALT button, and then press [F1] (PRE
READ) button to select off.
6 Check that no loop connections remain.
