Power conditioners are devices that protect your music gear which needs an electrical load, from any outlying behavior that can affect the performance of your equipment and the audio quality. Every city, state, and country delivers electricity in different qualities even though they try to maintain the same standards, more or less. The primary way in which this device will help you is by providing consistent power through a voltage regulating feature. Other important abilities of a power conditioner are noise suppressing and transient protection against power surges.

Because the market has quite a considerable large selection at your disposal, getting the best power conditioner out there is not very simple. There are some features you can look out for to get a firmer grasp on the whole idea of what makes a power conditioner worth its price.

1. Input Voltage Display

This is a useful feature to have for seeing how your input voltage fluctuates and to make you feel like it’s working. Another purpose is to show a digital readout to others, like to your clients for example and this will give off a positive impression.

2. Front outlet

This is a very practical thing to look for in a power conditioner. You can power lots of things quickly without having to go behind the rack. For extra convenience try to get a model with one or two front outlets.
