Professional Audio Player with Stereo Amplifier
Model: AM4-EA
- Plays MP3s and WAVs from Compact Flash
- Real Time Clock Scheduler and Playlists
- Serial or Parallel Control
- GPS Input
The Digital Audio Machine stores its sounds on Compact Flash cards, so playback is virtually instantaneous. You can create and edit your audio using your desktop PC. Then just copy the clip to the media or transfer it via the Ethernet option.
Clips may be triggered using external contacts or pushbuttons, serial RS-232 messages, Ethernet, playlists or the built-in real time scheduler. The unit can also simply loop continuously when powered. It fits almost anywhere, from dashboard to rack, and even works in high vibration environments, such as roller coasters! Power it with a 12V battery or the included AC adapter.
The Digital Audio Machine is also a terrific player for GPS-triggered transportation applications. When connected to a GPS receiver (see the accessories page), the Digital Audio Machine steps through cues automatically as it moves through user-defined geographical zones!

With our optional Digital Media Manager software you can manage one or hundreds of players, right from your desktop. Group players together for easy remote update of clips, playlists and schedules.
