[. . . ] The A-H4D can accomodate 4 additional Amplified Control Modules when used with the A-H4Dx Expansion Hub, which plugs into the side of the A-H4D. 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. 5 SOURCE 2 IR EMITTERS Common IR Outputs. Connect an IR emitter such as the 845. 1 to each of the 4 IR connectors on the front of the A-H4D (you need use only one IR emitter if you've connected a single source directly to the A-H4D). The IR signal that is received through a zone's Amplified Control Module is routed to the A-H4D's Common IR outputs. This allows remote operation of sources such as CD, DVD or DSS from each zone. Although the A-H4D has only 1 audio input, it can be connected to multiple audio sources via the Tape 2 or Zone 2 output of a stereo or home theater receiver. Connecting to a receiver gives the A-H4D access to any audio source connected to that receiver. If a single audio source is connected directly, it can be shared with the receiver by using the Audio Out on the A-H4D. 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. The Russound® A-KP2 Amplified Keypad (with built-in IR receiver) and A-VC Amplified Volume Control are examples of A-BUS® 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 Russound® A-PS 24VDC/2. 5A unit is an example.

The A-PS should be plugged into an unswitched AC outlet (one that is live all the time). 3 STATUS The status feature provides two functions: - Visually confirms when the source component is on - When the source component is turned off, all Amplified Modules will also turn off The status feature requires that the source component has a switched AC outlet. To enable the status feature: - Move the status jumper on all Amplified Modules to the "Enabled" position.
