Review ELECTRO HARMONIX 9v Power Supply

The Electro-Harmonix US9DC-100 is a versatile and high-performance 9V DC power supply, designed to meet the demands of musicians and audio enthusiasts. This power adapter comes with ten individually isolated 9V DC outputs, each capable of delivering up to 300mA of current to power multiple effects pedals or other 9V DC-powered devices.

The US9DC-100 features a center-negative configuration, which is the standard polarity for most guitar effects pedals. Each output has an LED indicator, providing an instant visual confirmation of power delivery. The power supply also includes an automatic voltage selection system, which can detect the voltage requirements of connected devices and adjust the output accordingly, making it a convenient solution for use with a variety of gear.

The Electro-Harmonix US9DC-100 is constructed with high-quality components and is built to withstand the rigors of live performances and studio use. Its robust design includes over-current protection, short-circuit protection, and over-voltage protection, ensuring the safety of both the power supply and the connected devices.

The power supply comes with interchangeable international adapters, allowing for easy use in various parts of the world. It also features a compact and lightweight design, making it easy to transport and set up. The US9DC-100 is backed by Electro-Harmonix's commitment to quality and customer satisfaction, making it an excellent choice for musicians and audio enthusiasts in search of a reliable and versatile power supply solution.

The Electro-Harmonix US9DC-100 is a 9V DC power supply designed to power multiple effects pedals. Here are some pros and cons that may help you decide if this power supply is right for you:

1. Can power up to 10 effects pedals simultaneously, making it a great option for those with a large pedalboard.

2. Each output has an LED indicator, allowing you to easily see which pedals are receiving power.

3. Has a total current capacity of 1.25A per rail, providing enough power for most pedals.

4. Compact design makes it easy to transport and use on the go.

5. Has a center-negative polarity, which is the standard for most guitar effects pedals.

1. Does not include any isolation between the power supply and the pedals, which may result in ground loops and unwanted noise.

2. The power cables for the individual outputs are relatively short, which may require the use of extension cables.

3. Some users have reported issues with the power supply overheating during use, although this seems to be a rare occurrence.

The Electro-Harmonix US9DC-100 is a versatile and affordable power supply option for those with multiple pedals. Its ability to power up to 10 pedals simultaneously and compact design make it a great choice for pedalboard users. However, it lacks isolation between the power supply and the pedals, which may result in noise issues for some users. If you're looking for a power supply to power a smaller number of pedals and prioritize isolation, you may want to consider other options.

If you have a large pedalboard and are looking for an affordable and convenient way to power multiple pedals, the Electro-Harmonix US9DC-100 is a solid choice. However, if you require isolation between the power supply and your pedals, you may want to consider a more expensive option with built-in isolation, such as the Voodoo Lab Pedal Power 2 Plus or the Strymon Zuma.
