Technical Specifications
Recommended Amplifier Power
ShowMatch full-range modules require two (2) amplifier channels with external DSP active crossover filters
(modules contain no passive crossover network). Each module contains series-parallel connections of four (4)
compression drivers delivering nominal 6-ohm impedance, with long-term power-handling rating of 100 watts
and peak rating of 400 watts. The low-frequency section contains parallel connections of two (2) woofers
delivering nominal 8-ohm impedance, with long-term power-handling rating of 450 watts and peak rating of
1800 watts.
ShowMatch subwoofer modules contain a single 18-inch woofer with nominal 4-ohm impedance, with long-
term power rating of 750 watts and peak rating of 3000 watts.
Selecting the proper amplifier size for a given loudspeaker requires analysis of the transducer long-term (or
RMS) power rating, dynamic range of the input-source material (crest factor), desired sound pressure levels,
and other factors. As a general guideline, to optimize ShowMatch system performance, the following amplifier
configurations are recommended.

Subwoofer
The Bose® PowerMatch® PM8500 Professional Amplifier (sold seperately) is easily configured to provide
the recommended amplifier power for ShowMatch modules and arrays. The PM8500 also provides presets
for all recommended signal processing, including active crossover, EQ, alignment delay, protection limiting,
array-compensation EQ settings, and cardioid subwoofer settings when used with the ShowMatch SMS118
subwoofer.
Recommended Signal Processing
Digital signal processing (DSP) equipment is required for infrasonic protection, crossover, equalization, and
protection limiting functions. The recommended active crossover for the ShowMatch full-range modules uses
the following filters in the Bose PowerMatch PM8500 professional amplifier or Bose ControlSpace® ESP (sold
separately).
