ElectroMagik

The  System is an animatronic control system developed by Chicago Semiconductor and AHF Animation Productions in 1998 for Carwardine Parks, used for controlling animatronics within Carwardine's properties. The system consists of a combined decoder & A/V switcher, with a DVD player (formerly a D-VHS VCR) connected to the ElectroMagik unit. The DVDs contain the show video along with the audio (on the right audio channel) and inaudible signals (on the left audio channel). The signal channel is sent to the ElectroMagik unit which retrieves and decodes the signals.

Trivia

 * On Rock-afire shows, the ElectroMagik equipment is hooked up to the greybox (or Blue Box). The data is carried to the greybox (or Blue Box) by way of a USB cable. When ElectroMagik was installed, certain parts of the old computer were no longer needed and removed, such as the old decoder board called the playback board. Data from the ElectroMagik equipment was then routed directly to the character driver boards.
 * When ElectroMagik was installed on AVG shows, the speakers behind the characters were no longer needed.
