Description

The Tone King Ironman II 100-Watt Precision Compensated Reactive Power Attenuator is your ultimate tool for taming the beast that is your tube amplifier. Designed to let you push your amp to its limits without pulverizing your eardrums, the Ironman II is not just a volume control—it's a tone-preserving powerhouse. Featuring a tuned reactive load and transformer-coupled attenuation, it mimics the impedance curve of a real speaker, ensuring your amp responds as if it's driving a genuine cabinet. This means you get all the rich, natural overdrive and tube saturation you crave, but at a volume that won't have your neighbors calling the authorities.

Whether you're recording in the studio or performing live, the Ironman II's analog cabinet simulation provides a balanced XLR output that captures the essence of your sound. Need versatility? The dual impedance controls allow you to match any speaker setup, and the Solo mode, activated by an included footswitch, grants you that extra volume boost when it's time to shine. Built to withstand the rigors of the road, this attenuator is as rugged as it is refined, making it a reliable companion for any gig.

Key Features:

  • 100-watt precision-compensated reactive power attenuator
  • Tuned reactive load circuit for authentic speaker impedance emulation
  • Transformer-coupled attenuation preserves amp tone at any volume
  • Balanced XLR output with analog cabinet simulation and dummy load capability
  • Dual impedance controls for matching amp and speaker setups
  • Solo mode with footswitch for volume boosts
  • Presence switch for brightness and compression control
  • Bypass mode disconnects attenuation circuitry from the signal path
  • Line-out jack for sending signals to mixers, audio interfaces, or other amplifiers
