User manual RUSSOUND A-H4D REV 1

[. . . ] 10. Grounding or Polarization - Precaution should be taken so that the grounding or polarization means of an appliance is not defeated. 11. Power Cord Protection - Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, receptacles, and the point where they exit from the appliance. 12. Object and Liquid Entry - Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through the openings. 13. Damage Requiring Service - The appliance should be serviced by qualified service personnel when: A. [. . . ] 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. 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 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 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. A-H4D KEY FEATURES 1) 2) 3) 4) 5) 6) 6) 7) 1 source audio input and loop output 4 common IR outputs Status power input with selector jumper (on rear) Power input Link In and Out Plug-in connection for A-H4Dx Expansion Hub Decora® faceplate (2-gang) Front-panel connections for Audio, IR Emitters, Power, and Status 6 POWER SUPPLY The A-H4D Hub and Amplified Control Modules are powered by the A-PS 24VDC/2. 5A power supply. 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. [. . . ] If service is necessary, it must be performed by Russound ®. The unit must be returned to Russound ® at the owner's expense and with prior written permission. Accidental damage and shipping damage are not considered defects under the terms of the warranty. Russound ® assumes no responsibility for defects resulting from abuse or servicing performed by an agency or person not specifically authorized in writing by Russound ®. [. . . ]
