【 Weak current College 】 public broadcasting system combining the right choice-the Cabinet--Power By 【 China power house network 】

For a reasonable allocation of the public broadcasting system, the preamplifier and power amplifier, regional switch control device and speakers of the matching functions of the broadcasting system has played a leading role, but on the other peripheral equipment configuration cannot be ignored, only designed to complement each other.
For device configuration with fewer small public broadcasting system, a power amplifier and a CD player, not to be stacked inside the Cabinet, in combination, like that are a waste.
For a large shopping centres or in the supermarket, the public broadcasting system, the number of device configuration will not be too small, you may need several sets of power amplifier or other device that's supposed to be equipped with a relatively high combination cabinets is reasonable. But in practice, a large shopping centre in, or shopping supermarket will be placed on the public broadcasting system desk that surface, and the help desk area often is too large to be a relatively high combination cabinets in it, is not an easy task. In such cases, according to our actual construction experience, there are two options:
One is based on the desk surface height and width, and height of the lower Cabinet combination, for a second (if required), at the service desk, convenient service operations and to conserve space.
The second method, decoration companies making service desk, forewarned construction personnel, according to the height of the use of equipment, will help desk here into a cell of a grid, for ease of wiring and ventilation, insulating layers behind is connected.
To sum up, a public broadcasting system would need to configure a combination cabinets? depending on applications.
If a public broadcasting system must be configured combination cabinets, then we should be how to choose?
Currently available, all public broadcasting systems and equipment are in accordance with 19-inch (equivalent to 483mm) international standard width to design and manufacture of, and therefore choose to Cabinet, must also be careful to choose the width of the international standard 19-inch rack.
The form from the cabinet can be divided into two kinds:
A simple Cabinet. This Cabinet strict sense, not a combination of the Cabinet, because it was simple to the extreme. The cabinet frame with aluminium decoration plate, rear sides of the Cabinet without doors, equipped with the standard interval for 1U mounting square hole, all devices rely on both sides of the front panel of the screws, since there is no configuration device guides, all installed in the equipment inside the Cabinet, are all in the suspension, for weight, heavy equipment, use this method to install is wrong and unwise. Since a long time, not by the device of Panel deformation, the device's Panel and from split to the enclosure. Use this cabinet there is a bad place to be, it is because the device Panel using a screw to fix, install it later will damage the surface of the device Panel, if the system acceptance problems, before the device will this side of the damaged equipment to suppliers require replacement, I'm afraid that none of the suppliers willing to unconditional replacement, of course, require a supplier for repair is no problem, but it need time!
The other is a general-purpose combination cabinets. This Cabinet is said that simple Cabinet to "solid". Behind doors, accessible, convenient equipment installation and debugging; some modelled network Cabinet also in the preceding configuration a glass door. Versatile combination cabinet cooling fan in General will be installed at the top.
And simple Cabinet, cabinet sides are equipped in accordance with the standard interval for 1U mounting square hole for all device installation screws, while in the after side of the column within the Cabinet is also equipped with the standard interval for 1U mounting side holes for mounting equipment Guide, which is installed in the Cabinet interior equipment will not be suspended. Due to the adjustment guide interval only 1U standard interval for the unit, so if you encounter non-standard height of equipment had to empty out a small section of space.
In the above two Cabinet, AMA Asia America public broadcasting system from internationally advanced combination of the advantages of the Cabinet, has launched a full-featured advanced aluminum combination cabinets.
AMA advanced aluminum composite cabinet with aluminum frame structure, open to all sides (left and right side of the cabinet door, rear side cabinet door), equipment installation and debugging extremely convenient and flexible.
AMA advanced aluminum combination cabinets, internal configuration of a number of guides, in-system debugging phase, depending on the system equipment, and the height adjustment device, good guide spacing (due to configure a back-slot, no need to 1U standard interval, you can set arbitrary height), all devices can be freely inserted and extracted, install the debugging is extremely convenient. As a result of relying on the rails support the device, the device front panel without installing screws, just after the system submitted to Cabinet overall aesthetic, and then install Panel retaining screws.

AMA advanced aluminum combination cabinets, side cabinet door above the configured temperature controlled fan. Temperature-controlled fan internal temperature according to the Cabinet and the automatic opening of exhaust air to the outside, thereby reducing the internal temperature of the Cabinet, ensure that all devices work in normal temperature range.
AMA advanced aluminum combination cabinets, internal also configured the lights on the back panel of the cabinet installed a light switch. This one is full of human design, installation and commissioning of the equipment, as well as future regular maintenance offers great convenience.
