Create soundscapes with the Poly-DAR, a polyphonic audio repeater that can play and mix up to 8 independent audio tracks simultaneously. The built-in 100-Watt amplifier directly drives speakers ensuring that your audio will be heard. Dual-zone mode turns each speaker output into an independent virtual audio player.  8 optically-isolated inputs offer a rich set of configuration options for maximum flexibility.  RS-232 and DMX-512 ports provide even more control by ride, show, and lighting systems. The latest firmware is always available right here and updating is as simple as copying a file to the SD card. Backed by a 3-year warranty, the Poly-DAR is a complete stand-alone audio solution designed for years of high-quality, rock-solid playback in your attraction or exhibit.
