Parallax 31316 AP-16+ Audio Player

Now controlling powerful, booming sound is as simple as loading up your SD card! The AP-16+ allows you to playback high-quality, stereo WAV files for your standard SD card through two, booming 20 W amplifiers (one per channel).

Advanced features like built-in randomization, auxiliary inputs, and the ability to use dry-contact, (optically isolated) 12 to 24 DC, or a PIR (or compatible) sensor put the AP-16+ in a class of its own. For stand-alone control the AP-16+ includes pre- and post-play delay potentiometers, as well as a relay that is active while your audio plays. Need background audio while your prop is idle? No problem, the AP-16+ includes an ambient loop control to do just that.
