The tone and performance of amplifiers are highly dependent on the input voltage supplied by the wall or other power sources. Variations in input voltage can significantly impact the overall sound and performance, and can even shorten the lifespan of components, leading to excessive repairs and frustration. That's where the BrownBox range by AmpRx comes in - it's a revolutionary lineup that allows you to discover and supply the optimal input voltage, ensuring you get a tone you love while protecting your gear in any environment.

When a valve amplifier is supplied with the proper line voltage, it will sound and respond as originally intended, revealing the circuit's true harmonic content and preventing unnecessary, expensive, and frustrating repairs. BrownBox users (including us here at Peach Guitar) consistently report that their amp's tone, touch, and feel have finally come together, providing them with improved harmonics and dynamic amp performance - allowing them to capture the elusive tone they've always wanted, every time, everywhere.

The BrownBox 200 is specifically designed for powering amplifiers and gear built for 220V in 220-240VAC/50Hz countries. It provides an adjustable voltage reduction, allowing users to fine-tune the voltage to the optimal level for their equipment.

  • Input: 220-240VAC, 50Hz; Standard IEC AC cable
  • Output: Two female IEC sockets, Adjustable Voltage Reduction
  • Power Handling: 2.5 Amps at 220-240VAC, 50 Hz, up to 440 Watts

Every BrownBox 200 ships with:

  • An IEC power supply cable
  • A multi-IEC adapter for powering amps with hardwired power cables
  • A male-female IEC cable for powering amps without hardwired power cables

Alternative Product - the BrownBox II

If you have gear built for 120V and need to use it in a 220-240VAC/50Hz country, the BrownBox II, when combined with a step-down transformer, is the perfect solution. It can also be used to correctly power 120V gear in 120V countries. Learn more about the versatile BrownBox II here.
