DESCRIPTION
Professional prop builders know a secret: audio is more than half of the experience of a high-quality prop.
Until now, most consumer-level audio boards lacked some real professional features -- features like quality
amplification, stand-alone randomization of sounds, relay control for automated output while audio plays, and
easy connections for manual and remote control. The AP-16+ is a high-quality, stereo WAV file player
designed for serious prop builders of all levels. It's very easy to use, yet rich in features, and is easily
integrated into props and displays.
