Palmer Power Attenuator - Control the volume of your guitar amp

The PDI06 is a power attenuator for live applications. The device is connected between the amplifier output and the speaker cabinet. It makes it possible to use the popular power stage distortion of tube amplifiers while reducing the associated high volume level. This permits practical volume reduction in five increments from 100% to 18% for stage and practice room situations. An additional level makes the speaker completely mute; the PDI06 then functions as a LOAD BOX and absorbs the entire output power of the amplifier.

This mode of operation is useful, for example, when connecting an amplifier equipped with a speaker cabinet emulation directly to the mixing desk using an existing line-out and loud 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 equal the value shown on the PDI06. Example: the outputs of a PDI06, that is 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 (tube) amplifier is also set to 8 ohms.

Special DI box with loadbox for guitars. The integrated load resistor permits tube amplifiers up to approximately 120 W to be connected to the PGA04, bypassing a loudspeaker. A jack socket (unbalanced) and balanced XLR connector are available for direct pickup of the signal. The extensive filter section provides for a realistic simulation of classic guitar loudspeaker sounds.

The Palmer PLB2X8 is a dual-channel, strictly reactive load (load box). A load box is a substitute for a speaker. It ensures that tube amps are connected to the correct load on the output, thus eliminating the risk of amplifier damage.

The PLB2X8 is a perfect addition to speaker simulators that do not have a built-in load (load box) (for example: PDI09, PGA05 and PDI05).

The PLB2X8 is also useful in conjunction with guitar amps that have a line out or filter out connection. In this case, the PLB2X8 permits silent operation of the amplifier with simultaneous use of the line/filter output.

The PDI09 can be connected between an effect device or amplifier and the mixing console. The PDI09 is not suitable for direct connection to a guitar. Integrated filter circuits simulate the authentic speaker" sound. Tone can be varied between "Mellow", "Normal", or "Bright".

The PDI06 is a power attenuator for live applications. The device is connected between the amplifier output and the speaker cabinet. It makes it possible to use the popular power stage distortion of tube amplifiers while reducing the associated high volume level. This permits practical volume reduction in six increments from 100% to 18% for stage and practice room situations. An additional setting mutes the speaker completely; the PDI06 then functions as a LOAD BOX and absorbs the entire output power of the amplifier.

This mode of operation is useful, for example, when connecting an amplifier equipped with a speaker cabinet emulation directly to the mixing desk using an existing line-out and loud volume levels in the recording booth are undesirable.

The total impedance of the speakers must equal the value shown on the PDI06. For example: the outputs of a PDI06 that is 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 (tube) amplifier is also set to 8 ohms.

The Palmer Speaker Simulator PDi 03 - available in 2, 4, 8 and 16 Ohm

The PDI03 Palmer speaker simulator combines load impedance, a signal splitter and DI box especially designed for guitars. All functions are optimised for live and recording applications.

Instead of being connected to a loudspeaker, the PDI03 is connected directly to the amplifier output. The signal is no longer picked up by a microphone, but after passing through a special filter section is fed directly into a mixing console, tape recorder, etc. This permits power amplifiers to be operated to saturation without troublesome volume problems.

Two switches select between the 9 filter presets simulating various types of speakers and enclosures. Open back 2 x 12' combo or 4 x 12' cabinet characteristics and the punch of a full-out stack with a graphic EQ 'V' setting can be selected as well as 'American' or 'British' speakers and ultra brightness.

Four paralleled unfiltered outputs are available for further processing. Both filter and line out level are adjustable.

For live monitoring, speakers may be connected while the reactive load is automatically switched off. Power handling capacity is 100W RMS without speakers.

The PDI 03 JB Speaker Simulator is a professional passive DI box for guitar amps. Providing a frequency compensated, transformer balanced direct feed to mixing consoles or soundcards it connects between the amplifier output and loudspeaker or equivalent dummy load. The PDI 03 JB has been developed for live, studio and home recording applications to eliminate the need for time consuming mic placement and mic-related problems.

Designed to Joe Bonamassa's high standards for a huge but tightly focused tone the exclusive JB switch brings the output signal to the fore and takes it right in your face." The PDI 03 JB's dual speaker simulation filters are carefully voiced to authentically replicate the frequency response of classic and contemporary loudspeakers and cabinets. The unit's input sensitivity is adjustable for amps up to 200 watts or line and instrument level equipment.

Delivering consistent guitar tone from show to show the PDI-03 JB can also be used to add realistic speaker flavors to preamps and dirt boxes in direct recording applications. The rugged powder coated steel enclosure features high quality Amphenol connectors and a ground lift to remove hum resulting from earth loops.

For amp DI WITHOUT speakers a dummy load with matching impedance must be connected. We recommend the Palmer Power Attenuator PDI06 and the Palmer Dual Load Box PLB2X8.
