Sync Circuit
PIN 1:
With SYNC REFERENCE switch set to
Inputs
DIGITAL,
this pin accepts an external
1/F
pulse at a
rate between 22.3-25.7fps (nominal 24fps) or between
1
6.7-19.2fps (nominal 18fps). Voltage swing must be
500mV minimum, 5V maximum. Virtually any wave
form with a 1/F repetition rate is acceptable. With
SYNC REFERENCE switch set to PI LOTONE, this
pin will accept the standard pilotone 60Hz sine wave,
1 volt rms, or any 60Hz signal between 0.7 volts rms
and 4 volts rms. Input impedance at Pin 1 is 15K ohms.
PIN 4: Sync signals entering Pin 4 go through an extra
stage of amplification and are then fed to Pin 1 as
above. Minimum acceptable voltage is 500
MV.
Input
i
mpedance at Pin 4 is 1000 ohms.
PIN 3: With SYNC REFERENCE switch set to
DIGITAL,
this pin accepts a
1/F
switch closure, at
the frame rates described above. Maximum "on"
resistance of the switch and cable connections that
will produce a guaranteed sync is 100 ohms.

Outputs
AUTOMATIC, LINE, and the S8S Recorder plugged
into a 60Hz AC line source, this pin provides a stand-
ard pilotone signal — 60Hz, 1 volt rms, suitable for
recording as a sync track.
Output impedance 1500 ohms.
PIN 5: Output of the servo-control wave form. This
is the signal whose average voltage is displayed on the
sync meter. Range 0-5V. Can drive an external sync
meter.
