ABUS-HUB4X8

Multi-Source Multi-Zone Hub

We hope you enjoy your ABUS system. Your ABUS component has been designed to give high quality sound and be simple and functional to operate.
All ABUS products bearing the ABUS logo are made to the ABUS standard, so when you connect an ABUS input device, hub or volume control module
they are compatible with each other. Some functions on some manufacturer’s products may not work with other manufacturer’s products; however, most
features will be interoperable. All ABUS components are simple to service or upgrade, so upgrading your system with components that offer improved
features should be easy.

The ABUS Multi-Source Multi-Zone Hub is the core of your ABUS system. It is the input connection point for the source components. It also distributes
power and sound to each room volume control module. It also repeats infrared (IR) commands to the source components. Multiple hubs may be used to
expand the system to more than eight rooms.
