Is a Power Manager Necessary for Home Theaters

Power managers are essential devices for anyone who wants to protect their home theater system from various power-related issues such as dirty electricity, lightning surges, and power outages. In this article, we will delve into the world of power managers, explore their purpose and advantages, compare them to similar devices like surge protectors, power regenerators, and UPS units, and provide you with our top recommendations for home theater power managers. So, let’s begin with the fundamentals.

Power managers, also known as power conditioners or power sequencers, are devices designed to regulate and improve the quality of electrical power supplied to your home theater system. They act as a barrier between the incoming power supply and your sensitive audio/video equipment, ensuring that only clean and stable electricity reaches your devices.

One common misconception is that surge protectors alone are sufficient for protecting your home theater system. While surge protectors are crucial for guarding against voltage spikes caused by lightning or power surges, they do not address other power-related issues. Dirty electricity, for instance, refers to electrical noise and fluctuations that can result from various sources such as appliances, lighting, and other devices connected to the power grid. These disturbances can introduce interference and affect the performance of your audio and video components. Power managers go beyond surge protection and actively filter out this dirty electricity, providing a cleaner power supply to your equipment.

Power regenerators, on the other hand, take power conditioning a step further. They not only filter out noise and fluctuations but also regenerate the incoming power, ensuring a constant and stable voltage output. This can be particularly beneficial if your area experiences frequent voltage sags or fluctuations.

What is a Home Theater Power Manager?

A home theater power manager, also known as a home theater power conditioner, is a sophisticated device designed to regulate the distribution of AC power. It offers surge protection and effectively filters out undesirable power issues, such as noise interference. Depending on its complexity and price, it may also include additional features like sequential system power ON/OFF and over/under-voltage protection.

Roles of a Home Theatre Power Manager

Another source of dirty power is known as normal mode noise, which refers to a low-level signal that accompanies the original power signal. In certain instances, if left unfiltered, this noise can even be audible through your speakers. Other equipment connected to the same power line can introduce this type of noise. Therefore, if you notice popping sounds or humming from your speakers when you turn on the lights or when someone activates a hairdryer, you are dealing with dirty power. A home theater power manager can effectively filter out this noise and enhance the performance of your home theater system. By utilizing a power conditioner, you will enjoy cleaner power and, consequently, a more pristine sound.

Enables You to Control Multiple Devices and Equipment from a Single Platform


A home theater power manager offers numerous advantages to enhance your entertainment system. One of its greatest benefits is the ability to control multiple devices and equipment from a single platform. Simplifying the management and control of your devices, you can effortlessly turn your entire home entertainment system on or off with just one click.

Furthermore, many power managers provide programmable outlets, allowing you to customize power sequences tailored to your devices. For example, you can configure your power manager to simultaneously turn on your TV and audio system while powering down other electronics like your DVD player or game console.

Why Do Some Audiophiles Oppose Power Conditioners?

Although not disputing the protective benefits of power conditioners, many audiophiles raise concerns about their impact on overall audio system performance. They argue that power conditioners can reduce or eliminate “dirty power” noise but may inadvertently remove some desirable sound elements. Consequently, audio reproduction may lose dynamics and sound lifeless. Notably, Paul McGowan from PS Audio suggests using one of their power regenerators as an alternative. While acknowledging the quality of their power regenerators, it is important to note that they are considerably more expensive than the average power conditioner.

However, for those unable to afford such high-priced devices, there is an alternative solution. Many audiophiles and home theater enthusiasts opt to install a dedicated power line, typically with the assistance of a professional electrician, specifically for their audio equipment. Unlike most power outlets in homes, which are shared with various appliances like refrigerators, routers, and light bulbs, a dedicated line eliminates the introduction of noise and enhances the performance of the home theater system. This solution offers cleaner power and sound without the need for a power conditioner, thereby preserving system performance. The cost of adding a dedicated line can range from $200 to $1000, depending on the complexity of the installation.

However, it’s important to note that a dedicated line alone cannot provide protection against power surges, under/overvoltages. For that purpose, a surge protector (preferably a power manager) is still necessary.

Differentiating Between a Power Conditioner and a Surge Protector

While surge protectors and power managers/conditioners share some similarities, they are not identical devices.

Surge protectors primarily safeguard equipment from surges, as their name suggests. Their main function is to divert excess energy away from the equipment by utilizing components such as Metal Oxide Varistors (MOVs) and gas discharge arrestors. However, surge protectors do not disconnect the equipment from the circuit. Consequently, during high-voltage events such as lightning strikes, surge protectors may absorb excessive energy, potentially leading to their own failure and causing damage to the connected equipment.

In contrast, most power managers utilize Extreme Voltage Shutdown (EVS) technology. EVS employs a mechanical relay that physically disconnects the equipment upon detecting a high-voltage event. This rapid disconnection ensures the power manager remains intact and functional. Therefore, power managers, like surge protectors, provide surge protection but in a different and arguably safer manner.

Furthermore, power managers offer additional functionalities. They incorporate filters to eliminate noise and deliver cleaner power to the equipment, resulting in improved sound quality. Some power managers also safeguard against under-voltage events, shutting down the unit to prevent excessive current flow. Additionally, home theater power managers often possess superior specifications compared to surge protectors, including lower clamping voltages and faster response times.

In conclusion, power managers or power conditioners are more advanced devices offering enhanced protection compared to surge protectors. They provide additional features and serve multiple purposes.

Some high-end power conditioners may help resolve ground loop issues, but there is no guarantee that purchasing a power conditioner will eliminate ground loop noise. It is advisable to try to identify the specific device or connection causing the ground loop and attempt to address it directly. For example, using a ground loop isolator (also known as an isolation transformer) on coaxial cables, which are commonly associated with ground loop issues, can be a cost-effective solution to eliminate the noise. These isolators are relatively inexpensive, usually costing less than $20, and can effectively resolve the noise problem.

Is it possible to daisy-chain power conditioners?

While it is technically possible to daisy-chain two power conditioners under certain circumstances, it is generally not recommended. It is best to connect two different power conditioners to separate wall outlets that are on different lines (breakers). If you still wish to daisy-chain two power conditioners, consider the current power draw and the equipment already connected to the first conditioner. Ensure that the load on a single wall outlet is not too high. However, it is still advisable to avoid daisy-chaining power conditioners if possible.

Is a UPS the same as a power conditioner?

No, a UPS (Uninterruptible Power Supply) and a power conditioner are not the same. A UPS provides a backup power source through a built-in battery, allowing you to continue operating your equipment for a few minutes during a power outage. On the other hand,
