Recommended Amplifier Power
Recommended amplifier power for each RoomMatch™ module is two (2) amplifier channels with external DSP active crossover filters
(modules contain no passive crossover network). Each module contains series-parallel connections of six (6) compression drivers
delivering nominal 8-ohm impedance. The long-term power-handling rating for the combined HF drivers is 150 watts, with a transient
peak rating of 600 watts. Each module also contains parallel connections of dual woofers delivering nominal 4-ohm impedance. The
long-term power-handling rating for the LF woofers is 500 watts, with a transient peak rating of 2000 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 maximize
the performance of the RoomMatch™ array modules in typical installations, we recommended using two (2) channels of amplifier power
per module as follows:

The Bose
PowerMatch™ PM8500 Configurable Professional Amplifier (sold separately) is easily configured to provide the recom-
®
mended amplifier power for RoomMatch™ modules and arrays. The PM8500 also provides presets for all recommended signal pro-
cessing, including active crossover, EQ, alignment delay, protection limiting, array-compensation EQ settings, and cardioid subwoofer
settings when used with the RoomMatch™ RMS215 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 RoomMatch™ full-range modules uses the following filters in the Bose PowerMatch™

Connector Wiring
The RoomMatch™ array module is equipped with two (2) Neutrik
an additional module. The connector is wired to provide separate amplifier channels to the high-frequency (HF) and low-frequency (LF)
transducers as follows:
