After you’ve spent hours deciding on which audio equipment to purchase, you shouldn’t rush to the installation. A proper installation is the foundation for longevity of any electronic equipment. Therefore, whenever you install new audio equipment, follow some basic rules and use common sense.
Audio gear can sometimes be stacked up. Stacking up multiple components can save space. However, before you start stacking, verify that the equipment is using a rugged enclosure. Usually, metal enclosures are most suitable for stacking multiple components on top of one another. Ideally, each component should use a standard-width rack. You should consider this fact before you actually decide on which components you purchase.
Another rule for stacking different components is to allow enough room for proper ventilation of every component which uses large amounts of energy such as a power amplifier. Power amplifiers usually have openings in top of the enclosure which allow heat to escape. If you start stacking other components on top of this amplifier, the air flow is impeded which can lead to overheating.
If you don’t have any choice but to place the power amplifier below another component, use some space is in order to maintain a gap of at least 1 inch between the top of the amplifier and the component sitting on top of the amplifier. This will allow sufficient airflow.
Also, when stacking up equipment, keep components which interface with one another right next to each other. This will shorten cable runs. If you have a component which uses a wireless feature then you should place this component on top of the other components. You never want the wireless components to be sitting in the middle amongst other pieces of equipment. This could cause blockage of the wireless signal. Ideally, this component will allow mounting of an external antenna. If that is the case then I recommend extending the antenna by using a short antenna cable.
When selecting interconnecting cables, use as short of a cable as is possible. The shorter the cable the less cable loss will occur. Also, minimizing the length of audio cables will minimize clutter. Loan cables can actually cause accidents if somebody was to trip over a loose cable.
I recommend using a surge protector for removing voltage spikes. Voltage spikes can be harmful to any audio equipment. I would recommend using a dedicated power strip just for your audio equipment. This power strip should connect via a surge protector. Clock all of your audio gear into that power strip. I also recommend selecting a power strip with the switch. When you are not at home then switch of the power strip in order to save energy. Being able to switch everything off also increases safety because it minimizes the chance of fire due to faulty equipment.
