Palmer Power Attenuator - Control the Volume of Your Guitar Amplifier

The PDI06 is a power attenuator designed for live use. The device is connected between the amplifier output and the speaker cabinet. It allows you to take advantage of the desirable power tube distortion from tube amplifiers while reducing the associated high volume. The volume can be practically reduced for stage and rehearsal room conditions in 6 steps from 100% to 18%. An additional setting completely mutes the speaker, allowing the PDI06 to function as a load box, absorbing the full power delivered by the amplifier.

This operating mode is useful when you want to play directly into the mixing console via an existing line output from the amplifier that features speaker emulation, and where volume in the recording room is undesirable. The device has an input for the speaker signal from the amplifier and an output for connecting a speaker cabinet.

The total impedance of the speakers must match the value specified on the PDI06. For example, a PDI06 rated for 8 ohms can connect to an 8-ohm cabinet or two 16-ohm cabinets at its outputs. The output of the tube amplifier should also be set to 8 ohms.
