Attenuate / Bypass Switch
This switch allows you to completely bypass the attenuator. In Attenuate mode, the
attenuator is active, and in Bypass mode, the attenuator is disabled. In Bypass mode,
the speaker outputs are connected directly to the amplifier input, and the attenuator
circuitry is completely disconnected from the signal path. Because of this, the
impedance matching switches (on the back panel) have no effect in Bypass mode.
Important - do not toggle the Attenuate/Bypass switch while playing through your
amplifier. Dampen the strings of the guitar while toggling this switch.

Attenuation Knob & Range Switch
The Attenuation knob determines the amount of power sent to the speaker. At 0db, the
signal is not attenuated, and all of the power from the amplifier is sent to the speaker.
The maximum possible attenuation is -40db. At this setting, nearly all the power from
the amplifier is dissipated in the Ironman, and very little is sent to the speaker. At this
setting, you can safely unplug the speaker, and use the Ironman as a dummy load.
Important - do not adjust the Range or Attenuation controls while playing
through your amplifier. Dampen the strings of the guitar while adjusting these
controls.
