GPStar Audio XL

GPStar Audio XL is a polyphonic audio player capable of playing up to 14 stereo WAV files at the same time. Layering, mixing, cross fading with independent track control of volume, pause, resume. 

A physically larger version than the smaller GPStar Audio, however GPStar Audio XL has 20 GP pins, which you can easily play and mix sounds without any coding.

With its larger size and GP pins, GPStar Audio XL is better suited for interactive installations or usages which require simple buttons to trigger sounds. Simply connect the 2 pins together with a simple press or toggle switch and it will play the sound file assigned to that GP pin.

It's onboard stereo amplifier is capable of driving 2 speakers (2.5W @ 4Ω or 1.25W @ 8Ω per channel) from the onboard amplifier and also has a stereo out auxiliary jack.

Pair it up with a GPStar Amplifier for the ultimate interactive sound experience.
