1. Quality Surge Protectors

Surge protectors are a must-have for protecting your home theater equipment. While you may already use a power strip with multiple outlets, it’s important to note that these are often not adequate in protecting against voltage spikes. A true surge protector (Our top picks) reroutes excess voltage to the grounding line, preventing it from reaching your connected devices.

Lightning strikes or surges in electricity from neighboring homes can cause voltage spikes that travel through electrical wires, potentially damaging sensitive electronics such as televisions, projectors, receivers, and speakers. Interconnected equipment in a home theater system is vulnerable to these spikes. A surge protector is the first line of defense against these spikes.

We recommend the Panamax PM8-EX (available on Amazon), which is more expensive than other surge protectors but has a proven track record of reliable performance. A high-quality surge protector is the number one way to protect your home theater equipment. If you’re interested in alternative options, check out our article on the top best surge protectors.

3. UPS (Uninterrupted Power Supply)

A UPS is a lifesaver for your electronics. It acts as a backup battery for devices that require constant power from an outlet. In case of a power outage in your home, the UPS takes over and provides power to all connected devices without any disruption.

UPS units are typically bulky due to the presence of one or more batteries. But the good news is that many high-quality UPSs also act as surge protectors and power conditioners. This makes them an all-in-one power distribution and protection device.

Having a backup power source is crucial for sensitive equipment, such as projectors. It gives them time to properly shut down, preventing any damage due to overheating. Proper shut down is also important for televisions and other electronic devices.

It’s always best to properly shut down your devices. For example, when you turn off your desktop computer, do you rip the power cable from the back or properly shut it down?

A great option to consider is the CyberPower CP1350AVRLCD (on Amazon). This unit not only provides backup power but also surge protects and conditions incoming power. It’s an all-in-one UPS with great reviews and a reasonable price tag.

4. Dust your equipment regularly

Protection of home theater equipment is critical and removing dust is an important aspect of it. Dust accumulates on and between the various equipment in a cabinet, room, or entertainment center. It’s essential to keep these areas clean to avoid damaging the equipment.

Many electronic devices come with a cooling system, be it passive or active. The presence of dust interferes with the cooling system and raises the internal temperature of the equipment. This can cause damage to sensitive components over time.

Electronic equipment with active cooling systems often has an in and out fan. The in fan draws air into the unit while the out fan expels it. Dust in an enclosed area can easily get sucked into the equipment and settle inside, leading to a buildup of dust over time.

It’s wise to use a duster regularly to clean our valuable electronic equipment. Keeping it free of dust will ensure it stays in good condition for a longer time.

5. Do not Stack Equipment on Top of Each Other

Stacking audio or video equipment on top of each other is not recommended. When the equipment is contained in a small, poorly ventilated space, it’s even more crucial to avoid stacking.

Audio and video equipment produces a lot of heat, and when they touch each other, the heat transfers easily. This can cause overheating, which can damage the delicate electronics. To prevent this, make sure there is enough space between each piece of equipment when using a rack system.

If you have all your equipment in an entertainment center or cabinet, using spacers between each device can be helpful. Consider using thick plastic or rubber spacers to reduce heat transfer between the equipment. Heat is a significant concern for most equipment, especially smaller devices without fans. By taking these precautions, you can keep your equipment in good condition for a longer time.

6. Add fans to improve airflow in your home theater

Fans play a vital role in cooling hot equipment. You’ll often see and hear them inside projectors, receivers, and computers.

If your equipment is in an enclosed space such as an entertainment center or decorative cabinet, the air can get stagnant. This is not ideal as the hot equipment can heat up the air around it. Hot air is damaging to most electrical equipment as it can cause sensitive components to reach temperatures that are higher than they can handle.

To overcome this issue, adding fans to move fresh, cool air to the equipment is the solution. For a cabinet, cut two holes and install an intake fan for cool air and an outtake fan to remove warm/hot air. Positioning the fans correctly provides a constant flow of air that will improve the performance and extend the lifespan of your equipment.

If the equipment is in an open entertainment center, there’s no need for fans. However, if it’s in a cabinet, consider purchasing a cabinet fan that can be powered by USB or a wall outlet like AC Infinity AIRPLATE S1, Quiet Cooling Fan System (On Amazon). This will ensure your equipment stays cool and functioning optimally.

7. Place the Equipment in a Ventilated Cabinet

One great option is to place your home theater equipment inside an enclosed cabinet. If it’s in a closet or small room, consider using a server cabinet. I suggest NavePoint 12U Wall Mount Network Server Cabinet  (On Amazon)

Many cabinets have built-in fans or pre-drilled holes for fan installation. The benefit of using a cabinet is that you can properly space out your equipment, allowing air to circulate. And if the cabinet is fully enclosed, it significantly reduces dust buildup.

To further protect your equipment, add filters to the fans and any open areas to block dust and other particulates. This will also improve the efficiency of the fans, bringing in cooler air and removing warm air. Using a server cabinet is a reliable way to protect your home theater equipment in many aspects.

8. Try To Limit the Volume Levels

One of the main ways that equipment can be damaged is by turning the volume up too loud.

Speakers have a limited power handling capability and pushing them beyond this limit can result in damage to the internal components. Similarly, a receiver has a maximum power output, and overdriving it can cause clipping. This is when the receiver is trying to deliver more power than it can handle and can result in overheating of the receiver or damage to the speakers.

To avoid this, it is recommended to set a maximum volume level in the OSD settings of the receiver. This will not only protect your home theater equipment, but it will also prevent accidental volume spikes that can harm your ears.

9. Don’t daisy-chain surge protectors, power strips, or UPSs

It’s important to note that daisy-chaining surge protectors, power strips, and UPS units can also lead to decreased performance of the equipment being protected. When you daisy-chain multiple power protection devices, the voltage drop can become significant and can cause performance issues, particularly for sensitive electronic equipment. This can result in problems such as brownouts, flickering lights, slow performance, or even equipment shutdown.

Additionally, in the event of a surge, if the first surge protector in the chain fails, it may not protect the rest of the connected equipment, leaving it vulnerable to damage.

To ensure the best protection for your home theater equipment, it’s recommended to use individual surge protectors for each piece of equipment and plug them directly into a wall outlet. This ensures that each piece of equipment is protected and receives the full voltage and amperage it needs to operate correctly.

10. Have a licensed electrician run high voltage power to your home theater

Hiring a licensed electrician is the best way to ensure that your high voltage power is installed safely and correctly. They have the training and experience to handle the potential dangers that come with high voltage power and they are knowledgeable about the electrical codes and regulations in your area.

Additionally, an electrician can assess your home’s electrical system and determine if there are any upgrades or modifications that need to be made to support your home theater system. This can include adding a dedicated circuit, upgrading the electrical panel, or installing a surge protector.

Remember, safety should always be your top priority when it comes to electrical work in your home. Don’t take chances with your safety or the safety of your family and always hire a professional electrician for any electrical work.

To Sum Up

In addition to these tips, it’s also important to regularly clean your home theater equipment. Dust and debris can accumulate on your components, which can cause issues over time. Clean your components regularly with a soft cloth and be careful not to damage any sensitive parts.

It’s also important to regularly check the cables and connections. Make sure that all cables are properly connected and free of any damage. If you notice any frayed cables or damage, it’s best to replace them as soon as possible to prevent further damage to your system.

Overall, it’s crucial to stay proactive in protecting your home theater equipment. Regular maintenance, protection from power surges, and proper cable management are key to ensuring that your system lasts for years to come.
