it is equipped with a loop programming facility. Transferring of 1/4" sound tapes with pilot tone recording and EBU/IRT time code. Exchangeable magnetic head carriers are available for heads for all track one and multi track arrangements in use. The device is laid out for the usual interlock and synchronous frequencies. The selectable sync sound speed, 24 or 25 fps, is crystal or mains frequency con¬ exactly counted by means of a toggle as: Film counter with computing micro¬ processor to convert all measuring data for length and time of any format fault¬ lessly by pressing the appropriate button. In connection with the editing machine this counter can be equipped with a search control for automatic stop and loop programming. Any data may be en¬ tered via a keyboard for computing and control purposes. All values and data are a limitless stored. The advance/retard counters feature trolled. Besides the such large variety of ac¬ cessories, many novelties are introduced to facilitate the work of professionals additional single frame mode. For time-saving, large ends of film may be displaced and single frame can be an switch. The modular-type amplifiers based on integrated circuits can be selected to groups according to requirements. For all channels there are group attenuators for volume, treble and bass. A dynamic compressor can be on additionally to raise low sound effects without having the amplifier boost to full output at loud switched sound effects. In addition a speech speed processor presented. This makes possible the understanding of speech even at multiple sync sound speed. ■ is (LEFT) ST 901 with ST 60-Editing machine for 16mm picture and 2 x 16mm magnetic sound tapes.
