    The Backline 1200 Plus expands on the capabilities of the Backline 1200 by incorporating Brownie voltage adjustment technology, providing both voltage reduction and voltage increase functionality.

     

    Designed for players and technicians who need greater flexibility, the 1200 Plus allows users to adjust incoming voltage in either direction while supplying up to four amplifiers from a single rack-mounted unit.

     

    Built-in voltage and current monitoring provide instant visibility into incoming power conditions, while hand-wired construction ensures reliability on the road and in the studio.

     

    About Brownie Technology:

    The Brownie is a voltage controller designed specifically for modern tube amplifiers, offering unmatched control, flexibility, and protection. The Brownie allows musicians to precisely adjust voltage in -1V increments (down to -7V) AND increase voltage +3V or +5V steps (max +5V), ensuring optimal performance.

     

    With wall voltage varying from 115V to 129V depending on location and various other aspects, the Brownie enables players to maintain a consistent tone and amplifier longevity.

     

    When a tube 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. Today, we should be receiving 120V AC from the wall, but depending on where you are and what time of day it is, you can receive anywhere from 120V to 129V. That’s not good for your amplifier, or your ears. AmpRx products offer flexible voltage reduction options that let you bring your power input down (or up) to an optimal level, resulting in significantly improved amplifier performance.
