AmpRx | The BrownBox II

Correctly Powers 120V Gear in 220-240VAC/50Hz Countries when Used with a Stepdown Transformer

The performance and tone of valve amplifiers are heavily influenced by the input voltage from the power source. Fluctuations in this voltage can harm sound quality and equipment longevity, leading to costly repairs. AmpRx's BrownBox range addresses this by enabling users to discover and maintain the optimal input voltage, thus enhancing tonal quality and protecting the gear. The BrownBox II is specifically designed for use with amplifiers and equipment intended for 120V in 220-240VAC/50Hz regions, when combined with a step-down transformer. It provides adjustable voltage reduction and improved dynamic performance, ensuring reliable, high-quality sound in any environment. Read more on this excellent product below.

Description

The tone and performance of valve amplifiers depend significantly on the input voltage provided by the power source. Variations in input voltage can adversely affect the sound and performance of your gear, and can shorten component lifespan, leading to excessive repairs and frustration. Enter the BrownBox range by AmpRx - it allows you to discover and supply the optimal input voltage, ensuring you achieve the tone you love while protecting your gear in any environment.

Supplying a valve amplifier with the proper line voltage enables it to sound and respond as originally intended, unveiling the circuit's true harmonic content and preventing unnecessary, costly, and frustrating repairs. BrownBox users (including us here at Peach) consistently report that their amp's tone, touch, and feel have finally come together, providing them with improved harmonics and dynamic amp performance - capturing the elusive tone they've always desired, every time, everywhere.

The BrownBox II is tailored for powering amplifiers and gear built for 120V in 220-240VAC/50Hz countries when used with a step-down transformer. It can also be used to correctly power gear built for 120V in 120V countries.

  • Input: 120VAC, 50-60 Hz; Standard IEC AC cable
  • Output: Two AC Grounded Outlets, Adjustable Voltage Reduction
  • Power Handling: 5 Amps at 120VAC, 50-60 Hz, up to 540 Watts

Why Choose the BrownBox II?

For instance, if you are in a 230V country like England but want to use an amp with a 120V power section, you can't simply plug it into the wall. You need a step-down transformer to convert from 230V to 120V, and then you can use the BrownBox II to fine-tune the voltage to the optimal level for your equipment.

Alternative Product Suggestion - the BrownBox 200

For those with gear built for 220V in 220-240VAC/50Hz countries, the BrownBox 200 is the perfect solution. It offers adjustable voltage reduction and comes with all necessary accessories. Learn more about the BrownBox 200 here.
