The 16ohms PDI06L16 Power Attenuator from Palmer can be used is live applications and allows for stage distortion of tube aplifiers while reducing the associated high volume level. The device is connected between the amplifier output and the speaker cabinet and permits practical volume reduction in six increments from 100% to 18%. A mute setting silences the speaker, allowing the device to function as a load box and absorb the entire output power of the amplifier. The PDI06L16 features an input for the speaker signal from the amplifier and outputs for connecting to a speaker cabinet.
