The Dolby Digital Soundhead CAT702 is a penthouse-type reader that bolts directly to many current and older film projectors. It enables playback of Dolby Digital and Dolby Digital Surround EX soundtracks through your cinema's Dolby Digital processor or digital adapter.
To read Dolby® Digital soundtracks reliably and accurately, the Dolby Digital Soundhead CAT702 uses the latest in LED longevity and CCD technology, including a video output level indicator for adjusting the LED array's drive current.
To ensure smooth film motion, the Dolby CAT702 features an easily threaded Davis tight-loop configuration with twin tension arms for superior film guidance.
Operating power is drawn from your Dolby cinema processor, eliminating the need for a separate AC connection. The CAT702 includes a 10-meter (32.8-foot) video cable for connection to the processor.
Whether you make, distribute, or exhibit movies, Dolby helps you deliver the kinds of experiences audiences associate with the best in cinema.
Consultants from Dolby support directors, exhibitors, and other industry pros to deliver the best possible movie experiences worldwide.
