TIME CODE/TIMER selector
This switch selects one of the following three kinds of
tape run time display on the display
®.
TIME CODE: This is used to indicate the SMPTE
time code. The CH3 INPUT switch on
the AE-03 board (refer to 1-6-3.)
should be set to the TC position. The
A-3 SEL switch on the AE-03 board is
used to select an external time code or
internal time code (when the optional
BKH-2015 is installed). The TC/U-BIT
switch on the BKH-20 15 (TC-14) is
used to change over the time code or
user bit indicator. Normally this
indicates a value read by the time code
reader but when the T APE/EE selector
CD
is set to INPUT, it indicates an input
from the time code generator.
TIMER-I: This is used to indicate the tape run
time by counting the CTL signal on
the tape. It is possible to zero reset at
any position on the tape with the
RESET button
(j).
After reset, the
new tape run time is indicated from
this point.
TIMER-2: This is used to indicate the tape run
time by counting the CTL signal on
the tape. When the tape is threaded,
zero reset of the TIMER-2 cannot be
performed.
The data of the TIME CODE, TIMER-lor TIMER-2
selected by this switch, which is indicated on the
display, can be entered as the edit IN or OUT point.
• Both TIMER-l and 2 start counting the tape run
time when the machine is in an mode except the
STOP mode. The TI~1ER-2 zero point is the position
where the operation mode is designated after the
tape has. been threaded. For TIMER-I, it is possible
to zero reset any position on the tape.
• When the power is turned OFF with the tape install-
ed, the data of TIMER-l and 2 is retained for 12
hours by means of a built-in back-up capacitor, so
that the data can be used again within this period.
