Another reason to get a home theater power manager is to reduce energy costs. Many power managers include features that help reduce standby power consumption. Standby power is the power consumed by electronics when they’re turned off but still plugged in.
While standby power consumption may not seem like a big deal, it can add up quickly.
In fact, the Department of Energy reports that standby power consumption accounts for about 5-10% of all residential energy use in the United States. By reducing standby power consumption, you can save money on your energy bills.
You Want To Improve the Home Theater’s Performance
If you want to get the most out of your home theater, a power manager can help. That’s because many power managers include features that help improve the performance of your system. For example, some power managers include line conditioners.
Line conditioners help improve the performance of your system by providing clean, stable AC power. That can improve picture quality, reduce video interference, and help produce clearer sounds.
You Live in a Place With Frequent Lightning Strikes
If you live in an area with frequent lightning strikes, a power manager can help protect your electronics from damage.
As mentioned, power managers work by redirecting the flow of electricity away from areas susceptible to power surges, such as those caused by lightning strikes. That can help prevent your electronics from being damaged by sudden increases in voltage.
In addition, these devices can help protect your electronics from being damaged by power outages. By keeping a steady flow of electricity flowing to your devices, power managers can help prevent your devices from being damaged by sudden changes in voltage.
As a result, a power manager can be an essential tool for protecting your electronics from damage in areas with frequent lightning strikes.
Home Theater Power Managers – Why Are They Worth it?

Now that we’ve looked at why you might want a home theater power manager, let’s look at some reasons why you might not want one.
Power Managers Filter Out Some Frequencies
In an effort to reduce electrical noise, power managers can filter out some frequencies. Unfortunately, this may also impact the sound quality of your system.
For instance, if you are using powered speakers, the power manager may filter out some of the low frequencies that these speakers rely on to produce a full, rich sound.
As a result, your music may sound thin or tinny. In some cases, it may even be difficult to understand the lyrics. If you’re concerned about sound quality, consult with an audio professional to determine whether a power manager is suitable for your system.
Power Managers Can Be Expensive
Another downside to power managers is that they can be expensive. In fact, depending on the features you want, a power manager can cost several hundred dollars.
If you are on a tight budget, a power manager may not be your best option. However, if you are willing to spend the money, a power manager can be a great way to improve the performance of your home theater and protect your electronics from power surges and lightning strikes.
Power Managers Require Maintenance
If you are unwilling to put in the time and effort required to maintain a power manager properly, it may not be the best option for you. These devices can be vulnerable to damage from dust, dirt, and other debris.
Dust can build up on the cooling fins, causing the unit to overheat. Dirt can also clog the vents and lead to premature failure.
As a result, it’s essential to regularly inspect power managers and clean them as needed.
Power Managers Are Not Foolproof
Despite their many benefits, power managers are not perfect. They cannot completely eliminate the risk of damage to your electronics from power surges or lightning strikes.
Moreover, power managers are only effective if they are correctly installed and maintained. If you are unwilling to put in the time and effort required to maintain a power manager properly, it may not be the best option for you.
What To Look For in a Home Theater Power Manager
Suppose you’ve decided that a power manager is suitable for you. In that case, there are a few things you’ll want to look for when choosing a unit.
The Voltage Must Match the Power Supply’s Output
Voltage is a measure of the potential difference in an electrical circuit. For electrical devices to function correctly, they must be connected to a power source with the correct voltage.
Power supplies are designed to provide a particular voltage level, and it is crucial to choose a power manager with an input voltage that matches the power supply’s output voltage. If the voltages do not match, the power manager will not work correctly.
It’s also important to note that the voltage rating of a power manager is not always the same as the nominal voltage of the power supply. For example, a 120-volt power supply may have a nominal voltage of 110 volts. In this case, a power manager with a 120-volt input would still be compatible with the power supply.
The Current Rating Should Exceed the Maximum Draw
When choosing a power manager for your home theater, it’s essential to consider the current rating. The current rating is the maximum amount of current that the power manager can supply.
It’s vital to choose a unit with a current rating that is higher than the maximum current draw of your devices. Otherwise, the power manager will not be able to supply enough power, and your devices may not work correctly.
The maximum current draw of your devices is usually specified by the manufacturer. You can usually find this information in the product manual or website. If you’re not sure what the maximum current draw of your device is, you can always contact the manufacturer.
Key Takeaway: Choosing a power manager with a current rating that exceeds the maximum draw of your devices is essential for ensuring that your devices will work correctly. Make sure to consider all of your devices when selecting a power manager so that you can choose a unit that will meet your needs.
The Surge Protection Rating Should Be High
Another important specification to look for is the surge protection rating. The surge protection rating measures how much voltage the power manager can handle before it fails. It’s essential to choose a unit with a surge protection rating that is appropriate for your devices.
The surge protection rating is usually specified in volts. The higher the rating, the more voltage the power manager can handle before it fails.
For example, if you have a home theater with devices with a maximum voltage of 120 volts, you’ll want to choose a power manager with a surge protection rating of 120 volts or higher.
The Response Time Should Be Fast
The response time is the amount of time it takes for the power manager to react to a change in voltage. It’s essential to choose a unit with a fast response time so that your devices are protected from sudden changes in voltage.
The response time is usually specified in milliseconds. The faster the response time, the better.
Some power managers have a feature called “line conditioning,” which can help improve the response time.
Line conditioning is a process that stabilizes the voltage so that it does not fluctuate as much. That can help protect your devices from damage caused by sudden changes in voltage.
The Warranty Should Be Long
When choosing a power manager, it’s essential to consider the warranty. The warranty measures how long the power manager will be covered in case of problems. It’s critical to choose a unit with an extended warranty so that you can be sure that it will last for a long time.
The warranty is usually specified in years. The more extended the warranty, the better.
Some power managers come with a money-back guarantee. That means that if you’re not satisfied with the power manager, you can return it for a refund. That can be a good option if you’re unsure if a power manager is suitable for your home theater.
Key Takeaway: Choosing a power manager with an extended warranty and a money-back guarantee is an excellent way to ensure that you get a unit that will last for a long time. Make sure to read the warranty carefully to know what is covered and what is not.
Extra Tip: Besides the above tips, be sure to read reviews before purchasing a power manager. Reviews can help you learn about the pros and cons of different models to make an informed decision.

Use a Surge Protector
A surge protector is a device that protects your devices from damage caused by sudden changes in voltage. When there is a sudden change in voltage, it can cause an electrical shock that can damage your devices.
A surge protector protects your devices by absorbing the shock and redirecting the excess electricity into the ground. That prevents the current from passing through your devices and damaging them.
These protectors are vital for home theater systems, computers, and other electronic devices, as they are susceptible to sudden changes in voltage. By using a surge protector, you can protect your investment and keep your devices safe.
Use Power Strips
Power strips are an excellent way to protect your devices from damage caused by power surges. They work by using multiple outlets to distribute the electricity evenly. That prevents too much electricity from flowing through one outlet and damaging your devices.
Power strips are handy if you have multiple devices that need to be plugged in simultaneously. By using a power strip, you can protect your devices and keep them safe.
Be sure to choose a power strip with surge protection so that your devices are protected from sudden changes in voltage.
Use Uninterruptible Power Supplies
Uninterruptible power supplies (UPS) are devices that provide backup power in case of a power outage. They work by using batteries to provide power to your devices when the electricity is out.
UPS systems are essential for home theater systems as they can keep the system running in case of a power outage. That way, you won’t have to worry about your movies being interrupted by a power outage.
Besides, using a UPS can also protect your devices from damage caused by power surges. That’s because the UPS will provide power to your devices even if there is a sudden change in voltage.
Unplug Devices When Not in Use
