AmpRx Brown Box Amplifier Attenuator 220-240V, 50/60hz

Product Description

The AmpRx Brown Box Amplifier Attenuator is designed to help tube amplifiers operate at reduced input voltages, allowing players to achieve the feel and response associated with lower mains voltages while protecting valuable equipment from excessive line voltage. Suitable for 220–240V AC power systems, the Brown Box provides stable and adjustable voltage reduction for amplifiers and can support rigs drawing up to 440 watts.

A proprietary transformer design developed specifically for tube amplifiers ensures reliable performance, while the back-lit LCD display provides real-time monitoring of voltage and current draw. Built with a rugged powder-coated enclosure and featuring silent, cool operation, the Brown Box is equally suited to stage, studio, and professional touring applications.

Supplied with a comprehensive accessory package, the Brown Box offers flexible compatibility with a wide range of amplifier power configurations, including dual-amp and parallel amplifier setups.
