Technical Specifications of Super8 Sound Recorder ti
Sync Section
Sync Socket PIN 1:With SYNC REFERENCE switch set to
Inputs 1/F, this pin accepts an external 1/F pulse at
a rate between 21-27fps (nominal 24fps) or
between 16-20fps (nominal 18fps). Voltage
swing must be 500mV minimum, 5V maxi
mum. Virtually any wave form with a 1/F
repetition rate is acceptable.
Sync Socket PIN 5: The output of the photosensor, a 1/F signal
Outputs that swings between OV and approximately
5V, is supplied on this pin, for use by an external
frame counter or catch-up correction
circuitry.
PIN 7: No Connection.
PIN 2: Ground.
Crystal Sync With SYNC REFERENCE switch set to XTAL, the
S8SRII will run at 24fps ± one frame in 13 minutes,
—10 to 40 ° C. (accuracy 0.005%-50ppm).

Speeds 24fps (4ips), and 18fps (3ips) using Super 8 fullcoat
magnetic film. Each speed is variable plus or minus
1 5%. Export model (S8SR50-1) is 25fps and 18fps
and can synchronize also at 24fps.

With SYNC REFERENCE switch set to
PILOTONE, 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
1 5K ohms.
PIN 3: With SYNC REFERENCE switch set to 1/F,
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
1 00 ohms.
PIN 4: This pin is prepared to accept an external
speed control input, to be used in the future
for catch-up sync circuitry.
PIN 6: This pin accepts a switching signal to ground
(PIN 2) that starts and stops the S8SRI I by
remote control (from a camera, for example)
