Interlocked

EN: Interlocked

Cinematografie

Two or more devices (most commonly dubbers in a mixing facility) with motors that run in sync are interlocked. It is not quite correct to say that a sync sound camera and tape recorder are interlocked, regardless of whether they use crystal of cable sync, since the tape recorder is recording pilottone and not really running with its motor interlocked with the camera motor.
