27、cessibility shall be housed. Head ends can be source head ends, distribution head ends, or both. Head ends typically serve as the terminus for head end equipment such as control point devices, speaker devices, in-living area/local control devices and in-living area/local sub systems (such as home th

28、eater systems). The head end area has specific requirements necessary to properly support installation, operation, and proper maintenance of the head end equipment. 3.2.1.1 Head End Location Although it historically has been common to locate a head end in a living area, housed in some form of “media

29、 cabinet,” it proves desirable for numerous reasons to locate a head end in an area apart from the common living area. Suggested spaces include a dedicated closet or equipment room, a structured wiring cabinet, a partitioned section of a basement, a crawl space, or a garage (where the environment ca

30、n be controlled properly). To facilitate efficient cabling of the home a central location within the structure is preferred. Head end locations should also provide ready access to service entrance points of all potential low voltage service providers. Where it remains preferable to install head end

31、equipment within the living space all head end requirements shall be met. 3.2.1.2 Head End Support Requirements At the source and distribution head end locations there should be sufficient space to support wire entry and wire management, to house a floor standing rack or hinged wall mounted rack or

32、shelving, and to provide easy access to both the front and rear of the rack(s) and/or shelving. At head end locations there also shall be an electrical supply consisting of a dedicated circuit(s) properly bonded and sufficient to supply a rated maximum load at least equal to the total load required

33、by all head end equipment, plus 30 percent or more for future expansion capabilities. There also should be sufficient air handling equipment to maintain the ambient temperature within the 30 degrees Celsius ( 85 degrees Farenheit), and to maintain the relative humidity within the range 30-60 percent

34、. (reference ASHRAE 55) The head end space should be well lit allowing for ease of reading all equipment labels and or documentation within the space. The head end space should also be relatively free of dust and insects. If enclosed, it shall have a door with a minimum width of 91.5 cm (36 in) for

35、ingress and egress. Racks should be installed in such a manner that does not impede proper access to the back of the rack. CEA/CEDIA-2030-A 8 3.2.1.3 Amplifier Rack Considerations Amplifiers, due to heat and weight should be placed on the bottom of the rack. Systems exceeding 500 watts should use ac

36、tive ventilation. 3.2.2 Non-Head End Source Inputs Non-head end source inputs are locations throughout the home where audio devices can be connected to the multi-room audio system for global access or local access. There are a variety of connection methods to connect both analog and digital devices

37、(such as analog line-level, Ethernet, proprietary digital) located where the homeowner may locate a desk, equipment rack, CD player, portable audio device, television, or other audio source. Source input devices located behind a desk or furniture may be located at the same height as electrical outle

38、ts. In casework or other built-ins, the source input device may be located behind the appropriate component (e.g., a television cabinet in a wall unit). It is recommended that source input devices be located next to or near a line voltage outlet as a convenience outlet for attached audio sources or

39、other use. 3.2.2.1 Global Source Inputs Global source inputs are non-head end source inputs that act as if they were located at the head end. Audio and control data signals injected at a global source input location may be carried back to the head end, distributed, peer-peer or may go to audio devic

40、es not located at the head end. Cables to this location shall consist of at least one category 5e or category 6 cable that runs from the global source input location to the source head end. For future use or higher bandwidth capabilities more category 5e, category 6 or fiber cables may be run to the

41、 head end. 3.2.2.2 Local Source Inputs Local sources are sources that are located within the proximity that one is listening. There are a variety of local sources such as iPod Docks, wireless content, etc. These sources, not located at the head end, may override the multi room audio system in the ro

42、om(s) in which they are located. Audio signals inserted at the local source input location may be carried to a local room preamplifier, amplifier or amplified speakers, or to other locations or to the head-end. There should be two cables, capable of handling the bandwidth requirements for the system

43、, to the control device location serving the area in which the local source input is located. 3.2.2.3 Speaker Level Local Source Inputs Speaker level local source inputs are speaker-level inputs that override the multi-room audio system in the room(s) in which they are located. The speaker-level out

44、puts of a local stereo system or television are injected into the speakers via a device at this location. 3.2.3 User Control Locations 3.2.3.1 In Room Analog Volume Controls In-wall analog volume controls usually are mounted at the same height from the floor as light switches or as provided for by m

45、anufacturer specifications. If the manufacturer recommends a specific housing for the volume control it shall be used. Although locations for installing a volume control within a room may vary, convenient access by the homeowner always should be a prime consideration. Volume controls installed at ei

46、ther side of a doorway provide a CEA/CEDIA-2030-A 9 convenient means of control when entering or leaving a room. Tabletop volume controls can provide a convenient bedside alternative. In-wall volume controls should not be installed in the same electrical boxes as 110-volt devices or adjacent to high

47、 wattage light dimmers because electromagnetic interference (EMI) generated by these devices may introduce noise in the form of hum or buzzing into the audio signal. Ideally, a minimum distance of at least one stud bay (16-inch on center studs) should be maintained between light dimmers and volume c

48、ontrols; more if multiple dimmers are being used. 3.2.3.2 Digital Keypads In-wall keypads usually are mounted at the same height from the floor as light switches, or as provided for by manufacturer specifications. If the manufacturer recommends a specific housing for the keypad it shall be used. Lik

49、e volume controls, keypads should be installed in user-friendly locations. Keypads should not be installed in the same electrical boxes as AC electrical power or adjacent to high wattage light dimmers because electromagnetic interference (EMI) generated by these devices may introduce noise onto the keypad data lines which may result in intermittent or total loss of system/source control. A minimum distance of at least one stud bay (16-inch on center studs) should be maintained between light dimmers and keypads more if multiple dimmers are used. Se
