[. . . ] If the sources are connected to an existing home theater system, you can share them with the A-H484 by splitting their audio outputs with "Y" connectors (see diagram). Model A-H484 Multi-Source, Multi-Zone Hub for A-BUS® System Instruction Manual A-BUS® SYSTEM OVERVIEW The A-H484 is an A-BUS 4-zone, 8-room, 4-source Audio Distribution Hub. Used with IR-repeating Amplified Keypads (e. g. , A-KP2) and the A-LRC-1 remote, the A-H484 allows each of 4 zones to independently select any of 4 sources. Each of the 4 zones can support 2 Keypads, making it possible to create an 8-room system. IMPORTANT ­ Before installation, review the manuals included with each component in your system. If you are unsure of any of the installation procedures described herein or elsewhere, consult a professional electronics installer. 6 POWER SUPPLY The A-H484 Hub and Amplified Keypads are powered by the A-PS 24 VDC power supply. Connect 1 Russound A-PS power supply to the A-H484 for each row (A and B) of 4 Amplified Keypads. The A-PS should be plugged into an unswitched AC outlet (one that is live all the time). When the A-PS is providing power, the A-H484's SYSTEM ON LED will illuminate, once an Amplified Keypad is turned on. The product you have just purchased is an integral part of the Russound A-BUS Multi-Room Audio System. It is a component which, when combined with other essential components and your source equipment (receiver, CD player, etc. ), creates a versatile whole-house audio system that will fill your rooms with high-quality sound for years to come. A-BUS technology is a new, innovative method of providing high quality audio to remote locations with a single 8-conductor cable such as CAT-5. A-BUS technology provides many advantages over other methods of audio distribution, including: simple, single CAT-5 wiring scheme; infrared control of system components; infrared control of the optional A-KP2 amplified keypad module; and system power status. Every A-BUS System is comprised of components from each of the following three areas. A-BUS Amplified Control Modules: The Module contains both the amplifier for the room's speakers as well as the control for those speakers. One Module should be used for each room you choose to control. The Russound A-KP2 Amplified Keypad (with built-in IR receiver) and A-VC Amplified Volume Control are examples of ABUS Amplified Control Modules. A-BUS Hubs: All components of the A-BUS system must be wired centrally to a Hub located near your source equipment. The Hub provides the connection for source equipment, volume controls, infrared emitters and power supply. The A-H484, A-H4, A-H4D, and A-H2 are examples of A-BUS Hubs. The A-H484, A-H4, and A-H2 are surface-mount units. The A-H4D is an in-wall Decora® style unit. Power Supply: The power supply plugs into the Hub. The Russound A-PS 24VDC/2. 5A unit is an example.
