JH-45 AutoLock (Refer to AutoLock manual for
detailed information.)
The MCI AutoLock is designed to lock an MCI
(JH-110B, JH-114) tape machine as a SLAVE to any
other MCI (JH-110B, JH-114) tape machine as a
master. Locking of slave to master is by the use of
SM TE, EBU or NTSC (drop frame) time code. Ac ­
curacy of lock is within 50 microseconds.
The remote control option is supplied in a
separate case with a connecting cable 30 feet
long. The schematic is in section 3 of this manual.
The case dimensions are: width — 11.5 inches;
height — 3.25 inches; depth — 2.675 inches.
The remote control unit provides full transport
motion controls including the " Joystick." In addi ­
tion it includes an LD (Lifter Defeat) button for
controlling the tape lifter from the remote posi ­
tion. When the Return To Zero option is included
with your machine, remote buttons are included to
control this option.
or slave in hours, minutes, seconds and frames.
Manual control of positive or negative slave offset
is provided from one frame to as many as needed.
The AutoLock generates a time code. Tape
discontinuities are overidden to provide free
wheeling lock. Locking is by means of a fast lock
or slow lock. Fast lock of slave to master is ini ­
tially fast wind to 25% of nominal speed, capstan
servo control to within two frames and absolute
lock by comparing time code synchronizing
detect pulses. Slow-lock maintains a maximum
variation of 1.45% of nominal speed (1/4 semitone
maximum variation).
Other features are the capability of incorporating
user bits into the time code. Storage of record
start and record stop tape position, when auto
record is pushed, causes recording start at a
preset time to the time matching storage of record
stop.
An additional capability is park of the slave
machine. A time position can be stored in the
display. ressing LOC causes the slave tape
machine to run up to the display position and
stop.
For specific details see the MCI AutoLock
manual.
