The H-9X28D Hydra™ from MedeaWiz is an Input and Output expander for the Sprite® media players.  It adds multiple trigger inputs and outputs, a motion sensor input, DMX512 or MIDI control input. The Hydra connects to the Sprite's serial port with the included 3.5mm 4-pole jack lead.  This connection also supplies power to the Hydra.

The Hydra's factory default setting is Mode 1. This enables 9 push button inputs plus a motion sensor input and 8 outputs. The first 8 inputs will play files named 001 – 008. The motion sensor input will also play file 001. The 8 inputs are non-interruptible. This means that once a file is triggered it will play through to the end. Any other triggers on any of the other inputs during this time are ignored. The corresponding output 1 – 8 will be active while the file is playing.  This output can be used to turn on a LED in the switch or activate a relay, etc.  Input 9 will interrupt and force the Sprite back to the looping file named 000.

The Hydra allows you to control and play video and audio media files on the Sprite using your DMX512 controller. Multiple Sprite media players, each with a Hydra IO expander, can be independently addressed and controlled from a single DMX512 controller via a single daisy-chained DMX cable.

NEW!  All new Hydras shipped with V4.40 firmware featuring new modes specifically developed for games, escape rooms, puzzle-solving applications and MIDI control. See Hydra User Manual V4.40 for details.
