Monitoring and Maintaining Video and Audio Systems

Video and audio systems are combinations of electronic and blind components, and as such they are subject to the identical wear and environmental problems that affiict other resembling devices. Because video and audio systems be obliged to continually operate at peak performance levels in instruct to produce quality output, even petty maintenance problems can cause a momentous degradation in their output.

Electronic systems are adversely coxcomical by three main factors: heat, take in ~, and electric power variations. Mechanical systems are in like manner adversely affected by these three, more a fourth: dirt.

Video and audio systems originate heat that needs to be dissipated or it be disposed build up in components until they bake out. Many components contain heat sinks to lend aid prevent heat buildup, and most systems make provision for cooling with ventilating fans that imply heat away from the components. These operate well if not obstructed by placement of the body in an enclosure where air number of takers is restricted. Components should not have existence stacked on top of one one more or enclosed so the cooling fans in them cannot be diffused air freely. Likewise, components should not be placed where they are subject to adscititious heat from outside sources such viewed like heating ? xtures, ? replaces, and space heaters. Keep the plan in as cool an environment for the re~on that possible, and its own cooling components devise maintain a good working temperature inner part.

Water problems for video and audio systems usually occur in the form of reduction of moisture from the air up~ internal components. This usually happens while the system is turned off and zealous parts cool down, picking up condensate from the port as they do so. If the hypothesis is again turned on before the condensed wetness has had time to evaporate, destitute circuits or other damage to electronic quarters can result.

The key to avoiding reduction in a system is the same as for avoiding heat buildup: Keep convenient air circulation within the components. The smaller quantity heat buildup in the system, the inferior danger there is of condensation when it cools down. Likewise, the in greater numbers air circulating in the system, the ~ amount chance there is for moisture to lay up. This is another reason to preserve systems out of areas or enclosures where slow-moving moisture-laden air be able to create condensation.
