6 PHONES jack and control
Connect stereo headphones with an impedance of 8
ohms, to monitor the sound during playback.
The control knob adjusts the volume.
It is possible to make a setting so that the output
volume from the MONITOR OUTPUT connectors is
controlled simultaneously.
In order that the output volume from the MONITOR
OUTPUT connectors can be controlled simultaneously, an
internal board switch setting is required. For details, refer
to the Maintenance Manual Part 1.

TC (time code) switch and indicators
This switch selects the time code displayed in the
lower control panel in the sequence: LTC

. The indicator corresponding to the
selection lights.
When AUTO is selected, the time code displayed is
VITC when the tape transport speed is up to half-
speed, and LTC when it is more than half-speed.

1) LTC: abbreviation of Longitudinal Time code. This time
code is recorded on a longitudinal track on the tape.
Reading is unreliable at low speeds, and not possible at
all during still playback.
2) VITC: abbreviation of Vertical Interval Time code. This
is inserted in the vertical blanking interval and recorded
on the video tracks. It can be read at low speeds and
during still playback, but not during high-speed
playback.

8 REMOTE buttons and RS-232C indicator
Press one of these buttons to select the device
controlling this unit.
1(9P): This unit is controlled by the device connected
to the REMOTE1-IN(9P) or REMOTE1-OUT(9P)
connector. The button lights.
2(50P): This unit is controlled by the device
connected to the REMOTE PARALLEL I/O(50P)
connector. The button lights.
RS-232C indicator: This indicator lights when this
unit is controlled through the RS-232C connector.
3) Drop-frame/non-drop-frame mode:
In the NTSC system, the actual frame rate is 29.97
frames per second. There is therefore a cumulative
discrepancy between the actual frame rate and the 30
frames per second rate on which time code is based. In
drop-frame mode, except once every 10 minutes, the first
two frames are skipped at the beginning of each minute
to keep the time code values in step with actual elapsed
time.
In non-drop-frame mode, the correction is not carried
out, and there is a discrepancy of about 86 seconds per
day between actual elapsed time and time code values.
