Our Comprehensive Buying Guide

 

Setting up a home studio or getting stage audio gear these days is no longer a challenging process. Thanks to the latest technological advancements, you can find high-performance equipment to record your music, engage in memorable stage gigs, or simply enjoy your favorite tunes at home.

The electrical gadgets and systems you use need a more complex approach in order for them to be protected against damaging electrical surges, voltage irregularities, and RFI/EMI. Here is where using a power conditioner and surge protector becomes essential for the safety of your gear and your performance quality.

If the question ‘do I need a power conditioner?’ has been on your mind, the answer is yes, as such a product will not only protect audio gear but the many electronics you use on a daily basis.

Whether you need the best power conditioner for home studio or the best power conditioner for guitar amp, there are a few factors to be considered before you decide on a model.

Power conditioner types

The market offers a variety of both expensive and cheap power conditioners, and finding the model that best meets your needs might prove to be a bit challenging. Considering the advantages provided by each power conditioner type available is the first step to take.

You will thus find the so-called passive-type filters that offer basic noise-attenuation benefits. Most cheap power conditioner models fall into this category, yet they may be more suitable for casual musicians and players.

If you use expensive audio equipment, and you need a power conditioner that not only protects your gear against surges and spikes, but that also reduces line noise significantly, a balanced transformer type of power conditioner or an AC regenerative type is a better choice.

The former comes with a balanced isolation transformer, hence the name, that will balance AC power feed and reduce noise in a much better and effective way for video and audio components.

The latter is much appreciated for regulating AC voltage, reducing noise, and correcting waveform symmetry. This may not be the most affordable power conditioner type on the market, yet it surely does a great job of delivering clean power to your equipment.

Choosing between these types may seem a bit difficult, but it is probably best to go for a power conditioner audio model that is built on the three-in-one approach, and that thus protects your equipment against surges, corrects the voltage, and reduces noise.

 

Design and specs 

Whether you’ve set your eyes on a Furman power conditioner or an APC power conditioner, taking a closer look at the specifications and design of the product you want to buy is the next thing to do after you’ve decided on the type of conditioner you want.

A good audio power conditioner should be designed in such a way to isolate the individual receptacles or power outlets it features in order to eliminate interference between its components.

Consider the noise suppression rating that is expressed in decibels when you need a power conditioner for your audio gear. The higher this rating, the greater the noise reduction.

Also, check the joule rating of the model you want to purchase. This one refers to the electrical power a suppressor is able to absorb before getting damaged itself. A high joule rating means greater protection.

Sound quality, blackout protection, and other considerations

As we’ve said before, a good power conditioner should not only protect your equipment against surges and spikes but should also reduce radio-frequency and electromagnetic interference. This is of great importance when you need such a unit for your audio gear; therefore, you might want to look for a model that filters such noise.

Since brownouts and blackouts may lead to data loss and other unpleasant events, it is best to get a power conditioner that offers battery backup. Auto shutoff options are also a great addition, and many affordable power conditioners come with such features.

The best audio power conditioner will not only help you protect your gear but will also make it easy for you to take advantage of its features. Look for a product that is easy to use, comes with enough outlets to power all the gear you use and has a power cord that is long enough to cover your specific needs.

Check out some power conditioner reviews as well before buying as you can thus find out more about a certain model that might not be mentioned in the product’s description.

 

 

Frequently Asked Questions:

 

Q: What is a power conditioner used for?

Power conditioners are devices built to protect various pieces of sensitive electrical equipment and are thus installed between the power source and an electronic system. What does a power conditioner do then? It can do various things depending on its type, but most products in this line can actually do more than just protecting your gear against power surges.

Such a unit, be it a big or small power conditioner, can detect voltage irregularities that can damage your equipment, correct the power supply in order to prevent lockup, and ensure continuous voltage to your system during brownouts and blackouts.

Many power conditioners, such as some of the power conditioner Furman models showcased above, also provide EMI/RFI filtering, which means that they can smooth out electromagnetic and radio-frequency interference that could otherwise lower the quality of an electronic system’s performance. These devices will thus protect your equipment, reduce noise, and correct voltage fluctuation.

Q: Do power conditioners really work?

If you choose and use the right power conditioners for your specific needs and equipment, then you are likely to see that they actually do what they say they do. However, this depends on a variety of factors, such as the sensitivity of the equipment you use and the quality of the power in your area or city.

For example, if you don’t live close to a Radio/TV transmitter or a power substation, then chances are that your equipment gets clean power, and what you probably need is surge protection. There is a whole power conditioner vs surge protector debate, and since we’ve mentioned surge protectors, such items provide protection against damaging voltage spikes.

Power conditioners, on the other hand, provide more than that. High-end models will reduce EMI/RFI and thus contribute to the audio and video quality of the various pieces of equipment you use.

If the power your electronics receive is clean, a power conditioner may actually not be necessary. However, if you live in an older house and the power you get is known to be ‘dirty’, you can benefit greatly from such a conditioner.

 

Q: Do power conditioners reduce noise?

When looking for an answer to questions such as ‘what is a power conditioner?’ and ‘what does it do?’, you’re likely to run into definitions that associate such units with surge protection and EMI/RFI filtering.

It’s true that many models available for sale these days are more than devices that provide your electronics with protection against voltage surges and spikes that could otherwise damage your systems.

High-end power conditioners come with RFI and EMI filtering capabilities and can thus reduce the noise in electrical lines that result from TV/Radio stations, mobiles, and other such devices. If this noise gets into your audio/video systems, their performance will show it.

By reducing such noise, a power conditioner can thus improve the sound quality of the equipment you use. However, making sure that you get the power conditioner that meets your specific needs is compulsory.

Ask for a professional’s help and read a power conditioner review before buying as using models that are not suitable for your requirements might actually make the noise problem worse.
