AmpRx Backline 2400 Pro Voltage Attenuator

The Backline 2400 Pro represents the most capable and flexible voltage management system in the AmpRx lineup. By combining the proven voltage reduction capabilities of the Original BrownBox with the voltage increase and decrease functionality introduced in the Brownie, the Backline 2400 Pro provides unparalleled control over the voltage supplied to your amplifiers. Designed for professional touring rigs, studio installations, fly dates, and complex backline systems, the 2400 Pro features two independent voltage adjustment channels with dedicated monitoring and controls for each side. This allows technicians and players to optimize voltage for multiple amplifiers simultaneously while accommodating both vintage and modern equipment within the same rig. Built-in voltage and current monitoring provide real-time visibility into incoming power conditions, while independent controls on each side allow users to fine-tune voltage to meet the needs of their specific amplifiers and applications. With eight grounded AC outlets, dual-channel operation, and up to 2400 watts of total power handling, the Backline 2400 Pro delivers the flexibility, consistency, and control required by today's most demanding touring and production environments.
