The AniMaster EM-51A is a prop learning controller with stereo MP3 audio, two solid-state DC drivers and one mechanical relay (AC/DC) for Halloween and other applications. Up to three external devices can be independently controlled in synchronization with the audio. Animation programming is done via the Teach-n-Learn(tm) scheme allowing up to 2 minutes of animation to be programmed into the unit by manually playing through the sequence once.

The animation can be triggered by a wide range of mechanisms such as floor mat, infrared sensor, micro-switch and etc. The system can be configured to start the animation immediately upon triggering, or delay for a preset amount of time. When not triggered the system can optionally play background music loop (ambient sound). Maximum audio power is 10W per channel (left & right). A line out is also available for feeding an external power amplifier when necessary.
