RockBoard RPA 100 Power Attenuator – 100W Reactive Volume Control with Dummy Load & Cab Simulation

The RockBoard RPA 100 Power Attenuator is a powerful and versatile solution for guitarists who want to achieve the full tonal potential of their amplifier at manageable volume levels. Designed for amplifiers rated up to 100 watts, the RPA 100 lets you push your amp into its sweet spot—including natural power amp saturation and high-gain tones—while reducing the speaker output volume without compromising your sound.

Ideal for tube amplifiers, the RPA 100 functions as both a power attenuator and dummy load, making it possible to use your amplifier safely even without a connected speaker cabinet. Multiple impedance inputs for 4, 8, and 16 ohms ensure proper matching with virtually any compatible amplifier and speaker setup.

Beyond attenuation, the RPA 100 expands your recording and live performance capabilities with a balanced XLR DI output, line output, and headphone output. Built-in cabinet simulation delivers realistic speaker-emulated tones, with selectable 2×12″ and 4×12″ cabinet voicings inspired by the classic V30 speaker and SM57 microphone combination. A cab simulation bypass switch is also provided for use with external IR loaders or cabinet simulators.

For silent practice sessions, simply connect headphones and use the AUX input to mix backing tracks or drum loops from your smartphone, tablet, or media player while enjoying your amplifier’s authentic tone.

Constructed with robust components and active cooling via an integrated fan, the RPA 100 is built for dependable performance in studios, rehearsal rooms, and live environments.
