Introduction

Thank you for purchasing the Poly-DAR polyphonic audio repeater. Capable of playing and mixing up to 8 audio

tracks simultaneously through a built-in 100W amplifier, it can create interactive soundscapes that react to an

environment rather than just simply playing in the background. The Poly-DAR replaces numerous pieces of

equipment with a single, small box freeing you up to focus on your vision.

This rugged, versatile player was designed to make your attraction or exhibit that much more awesome for years

to come and we think you’re going to love it!

Operation

The Poly-DAR has 8-voices of polyphony. Polyphony describes how many sounds a device can play

simultaneously. Each “sound player” within that device is referred to as a voice.

Behind the scenes, the voice manager is responsible for finding an available voice to play the next requested

track on. When a track is triggered, the manager will first look for any unused voices and if none are available, it

will “steal”the oldest-playing voice that can be taken. Triggered sounds configured as DoNotDisturb cannon be

stolen by the voice manager.

All eight voices are mixed down to a single stereo pair which is fed to the internal amplifier.

Dual Zone Mode

Dual zone operating mode allows for one Poly-DAR to provide independent audio for two zones. Each speaker

output feeds a zone and the 8 trigger inputs and voices can be divided between them as needed. Each zone has

its own startup or triggered ambient track set and triggered sounds can only duck the ambient level in the zone

that they are assigned to. There can only be one ambient track playing in each zone at any time. The above

polyphony rules apply per-zone and neither zone can steal voices from the other.

In this mode, the Poly-DAR is still playing stereo files which must first be panned hard left for zone 1 and right

for zone 2. We provide Audacity macros that automate the process by mixing both channels of a stereo track

down to a single channel for either zone.

Using stereo tracks in dual zone mode allows for creative solutions such as playing common ambient sounds or

announcements across both zones simultaneously using only a single voice.

Standard Mode

In standard operating mode, up to eight voices

and triggers interact in one single group with

the above polyphony rules applied across all. A

startup or triggered ambient track set can be

configured, with any of the eight inputs triggers

able to duck the ambient content as needed.

Note that only one ambient track can play at a

time in this mode.
