the SHUTTLE dial to the center position after
turning it, otherwise the dial is moved by vibration
and the tape may start running in the shuttle mode
during playback.
4-1-4 Noiseless Playback
Function and Frame Step
Playback Function
When you are using the Betacam SX or MPEG IMX
format, you can put this unit into noiseless mode for
noiseless jog and shuttle playback at up to ±0.5 times
normal speed. During noiseless playback, audio is
muted for the MPEG IMX format. For the Betacam
SX format, discontinuous audio in frame units is
heard. In noiseless mode, you can use the PF-1/2
buttons to step through frames. The step for the MPEG
IMX format is 1 frame. The step for the Betacam SX
format is 2 frames.
To select noiseless mode
In the setup menu, set basic menu item 025,
NOISELESS to Enable. (The factory default setting is
Disable.) JOG or SHTL flashes in the display section.
To perform noiseless playback
Put the unit into noiseless mode, press the JOG or
SHUTTLE button, and rotate the JOG/SHUTTLE dial.
This allows you to perform noiseless playback at up to
±0.5 times normal speed.
In noiseless mode, the emphasis is on slow-speeds.
Therefore the SHUTTLE dial speed settings change
from the Normal (0), ±0.03, ±0.12, ±0.5, ±1, ±2, ±10,
±35 (Betacam SX format) (15 steps) to 0, ±0.03,
±0.06, ±0.12, ±0.25, ±0.5, ±1, ±10 (15 steps). For the
MPEG IMX format, extended menu item 922 of the
setup menu IMX NOISELESS PB allows you to set
the playback picture to FRAME, FIELD 1, or FIELD 2
(the factory default setting is FRAME).
