All tube amps — especially vintage tube amps — are designed to run at an optimal voltage, and standard wall current is typically too high. Designed for maximum flexibility, the AmpRX Backline 2400 Plus brings Brownie voltage control to professional touring and studio environments, enabling you to adjust incoming voltage in either direction to optimize your tube amplifier’s sound and longevity. Always providing the proper power, the rackmountable Backline 2400 Plus accommodates eight tube amplifiers, bolstered by two independently adjustable channels with four outputs per side, making it ideal for musicians who run multiple heads in a live-in rack case. You also get a high-visibility LCD to monitor your power conditions in real time. Boasting handwired construction, AmpRX’s Backline 2400 Plus is a must-have tool that's equally capable of extending the life of a classic vintage tube amp and tracking down the voltage sweet spot of a modern boutique creation.

Protect your amp — and your tone!

As any of Sweetwater’s tube amp devotees will tell you, improper voltage can be a danger to your tube amp’s health, subjecting the components to unneeded wear and opening the potential for serious and expensive damage. While that's more than enough reason to hook up the Backline 2400 Plus to your tube amps, there’s another element to the equation: tone. Outside of very niche scenarios, running your amplifier at the voltage intended by its manufacturer is the simplest way to achieve its optimal tone and dynamics — a task that the Brownie can tackle in mere seconds.

AmpRX Backline 2400 Plus Features:

  • 2 x 1,200W voltage controller for electric guitar rigs
  • Brings Brownie voltage control to professional touring and studio environments
  • Installs in a matter of seconds, allowing you to modify your mains voltage in either direction
  • LCD provides clear visual confirmation of your power conditions
  • Protects your amp from potential damage and wear caused by mismatched voltage
  • Optimizes your amp’s sound by allowing you to hear it as the manufacturer intended
  • Ideal for musicians taking their treasured gear out on the road
  • Rackmount design is great for musicians who run multiple heads in a live-in rack case

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
