Includes Auricon sound on film recording amplifier. Labs associated with print sound to a final release print are not used. This camera can be used with regular 16mm film stock and sync external audio for later digital edits.

The Auricon can also be used just as a regular film camera. CP-16 and Auricon are very similar. The CP-16 and CP-16R camera use Auricon parts for their movement. Many CP cameras can be opened up to find "Bach-Auricon" stamped right inside.

Auricon cameras were 16 mm film Single System sound-on-film motion picture cameras manufactured in the 1940s through the early 1980s. Auricon cameras are notable because they record sound directly onto an optical or magnetic track on the same film as the image is photographed on, thus eliminating the need for a separate audio recorder. The camera preceded ENG video cameras as the main AV tool of television news gathering due to its portability–and relatively quick production turn-around–where processed negative film image could be broadcast by electronically creating a positive image. Additionally, the Auricon found studio use as a 'kinescope' camera of live video off of a TV screen, but only on early pre-NTSC line-locked monochrome systems.

Auricon cameras were used primarily by news and documentary filmmakers. They had also found favor with independent and experimental filmmakers such as Paul Morrissey because of their ability to record long takes with sound on film. Eventually, they were replaced by lighter, self blimped battery powered reflex cameras such as the CP-16, which also had the ability to record sound on film.
