Conditions For Synchronizer Use
- All transport tallies are low true.
- Synchronizer must read tach pulses in fast wind as machines won't read time code at high speeds without circuit modifications. Also, tape lifters would need to be defeated in all modes which is not suggested by Otari.
- Synchronizer must be able to control capstan speed by varying a DC voltage. This voltage is ± 13v on machines with locator connectors and ± 3v on machines without locator connectors.
- Synchronizer must supply dry contacts for speed bypass during non-synchronizer use to provide calibrated speed. If cable is removed while in EXT capstan control, the machine will not operate at calibrated speed unless a dummy plug is installed.
Note:
On machines with locator connectors, the choice of internal or external capstan control is located on the control PCB. When switched to EXT., the pitch control will not function even though the LED will light when the pitch knob is pulled on.
