INTRODUCTION
Thank you for purchasing this 6-Zone Home Audio Multizone 12-channel Amplifier! This
amplifier is a 12-channel audio distribution amp that can be configured for six stereo 4-8
ohm zones, six stereo 70/100V constant voltage zones, or three high powered 8-ohm
bridged zones. It supports any combination of stereo, bridged, and constant voltage zones.
Each zone can be controlled using the included IR remote control or RS-232 computer
control. The RS-232 section is bi-directional, with an easy to configure command structure.
It can be configured to automatically send zone status updates or respond to queries to
confirm zone status and settings.
It has an Audio Bus IN, which can be manually selected using the remote control, RS-232
commands, or a voltage trigger. The voltage trigger will switch the zone to use the Audio
Bus IN as long as there is voltage present on the zone Line / Bus Trigger IN. When the
voltage is removed, the zone automatically switches back to the zone Line IN, making it
ideal for global paging across an entire facility.
Additionally, each zone has a Mute Trigger IN, which mutes zone audio when voltage is
present. Each zone also has a +12 VDC Status or Control OUT, which can be used to activate
a zone specific voltage controlled device or otherwise indicate zone ON/OFF status. Audio
is rounded out with a built-in -20dB audio limiter for each zone, designed to prevent
incidental peaks from becoming irrevocable problems.
Finally, each zone features a Remote Bypass switch, which allows or blocks IR and RS-232
control for those zones that you want to set and not mess with again. You can select 110-
120 VAC or 220-240 VAC input voltage, allowing the amp to be used anywhere there is AC
voltage. It is rack mountable, with removable rack ears for shelf mounting.
