Palmer PDI-05
Stereo Speaker Simulator


The Palmer PDI-05 is equally at home in the studio or onstage. Originally developed for the preamp/multi-effect/power amp combination popular in the late eighties and nineties, this authentic reissue is also suitable for heads and combo amps. What's more, the precise frequency correction of the stereo speaker simulator turns overdrive and distortion pedals or multi-effect units into a genuine preamp with an authentic sound. The PDI 05 lends digital keyboards and drum machines fullness and analog warmth without complex and time-consuming post-processing at the mixing desk. A built-in headphone amplifier permits "environmentally-friendly" practicing; its high output power even permits direct connection of ordinary hi-fi speakers.

The stereo speaker simulator is active; the power supply is permanently installed. It can also be operated in mono mode and with power amps (in this case, the power amp must always be connected to speakers or a corresponding load, for example the Palmer PDI 06 loadbox).

The PDI-05 makes conventional miking unnecessary and provides for a perfectly isolated signal without interference from other instruments and without feedback.
