NUX Zeus Jr. - Isolated Power Supply for Effects

In the world of modern electric guitar, sound purity is paramount, and often the biggest issue isn’t the effect itself but how it’s powered. Traditional methods like power chains can introduce unwanted hums and buzz that spoil the tone. The NUX Zeus Jr. answers these challenges by delivering an advanced solution for demanding musicians. This compact power supply is engineered to eliminate interference while providing stable power for your entire effects rack.

Product Features

The unit stands out with 6 fully isolated DC outputs, essential for avoiding ground loops. Each output has its own isolation, guaranteeing ultra‑low noise regardless of the pedals connected. The NUX Zeus Jr. also boasts high energy efficiency and voltage regulation on selected sockets, enhancing versatility. Thanks to a lightweight and compact chassis, it fits easily under any pedalboard.

Pure Sound Without Compromise

Many guitarists, especially those using high‑gain distortion, struggle with noise when linking analog and digital effects on a single power supply. NUX changed that approach by creating the Zeus Jr. with advanced switched isolated transformers instead of traditional toroidal transformers. This solution not only delivers higher energy efficiency (average 76.7% at 15V input) but also dramatically reduces weight and size. The output self‑regulation system provides ultra‑low impedance, preserving playing dynamics and preventing signal compression.

Unlike simple multi‑stage filtering solutions, the NUX Zeus Jr. employs technology that eliminates noise at the source. Each of the 6 outputs is powered by an individual switching transformer. Thus, even when powering demanding digital effect processors such as Eventide or Strymon, you needn’t worry about interference. The availability of regulated 9V, 12V, and 18V lets you tailor power to specific pedal needs, which can significantly shape tone characteristics, especially for fuzzes and phasers.

Applications

• Powering high‑gain distortion effect racks without background hiss
• Safe power for digital effect processors (DSP) that require stable current
• Universal power for mixed pedalboards (analog + digital) in studios and on stage
