Notes for Power Ratings
For reference, the following two examples illustrate two different output configurations using RoomMatch™ array module loudspeakers.
Front panel configuration settings are provided. While not covered in this documentation, ControlSpace
additional configurability to these examples. Further information on this software can be found on pro.bose.com.
Configuration of a RoomMatch™ Four-Module Array (example 1)
In this example, four full-range RoomMatch array modules are connected to one PowerMatch™ amplifier, arranged as follows:
(2) Bose® RoomMatch 7010 array module loudspeakers (70° H x 10° V)
(2) Bose RoomMatch 12020 array module loudspeakers (120° H x 20° V)

Front Panel Configuration Menu Settings:
1. MAiN MeNU < CoNFig < oUTPUT CoNFig
Set the output configuration for channels 1-8 to MONO mode.
2. MAiN MeNU < DsP < sPeAkeR PReseTs
For channels 1, 3, 5, and 7 set SERIES to "RoomMatch" and MODEL to "RM_Array LF."
For channels 2, 4, 6, and 8 set SERIES to "RoomMatch" and MODEL to "RM_Array HF."
3. MAiN MeNU < DsP < ARRAy eQ
For each input channel (A-H) that is routed to an output channel, set the MODULES value to 4 and the V-Angle parameter to
60 degrees, which is the total vertical angle of the four shown modules. Ensure that the state of the Array EQ is toggled to ON.
