Palmer PDI 06 L16 - Power attenuator 16 ohm

PDI06 is a power attenuator for live use. The unit is connected between the amplifier output and the speaker cabinet. It makes it possible to use the popular power amp distortion from valve amplifiers while reducing the associated high volume level. This provides practical volume reduction in five steps from 100% to 18% for use on stage and in the rehearsal room. An additional step mutes the speaker completely; PDI06 then functions as a LOAD BOX and absorbs the amplifier’s entire output power.

This operating mode is useful, for example, when connecting an amplifier equipped with a speaker cabinet emulation directly to the mixing console via an existing line-out, and high volume levels in the recording booth are undesirable. The unit has an input for the speaker signal from the amplifier and two outputs for connecting speaker cabinets.

The total impedance of the speakers must match the value specified on the PDI06. Example: The outputs of a PDI06 specified for 8 ohms can be connected to one 8-ohm cabinet or two 16-ohm cabinets (the 16-ohm version has only one output). The output of the (valve) amplifier is also set to 8 ohms.
