Super8 Sound Recorders Technical Specifications of Super8 Sound Recorder Sync Section Sync Socket Inputs
PIN 1:With SYNC REFERENCE switch set to 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. 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 s witch 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)
