Recommended Amplification for Installed Applications

Bose Professional recommends the use of Bose PowerMatch PM8500 series amplifiers for applications where the
system will be permanently installed. Two configuration options are available:
Economy (-2.6 dB peak output in module LF)
This configuration is ideal for applications that do not require the full peak output of the LF section of the array to meet
customer SPL requirements. In this set up a single Voltage Bridged (VBr) channel is used to drive two LF sections and
a single Mono (M) channel is used to drive two HF sections within the array. A single Quad Bridge (QBr) channel is used
for each SMS118 subwoofer.
