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® Designer™ software provides 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)

(1)Bose PowerMatch PM8500 configurable professional power amplifier

Figure 15. RoomMatch four-module array configuration

Note: All RoomMatch loudspeaker connections use Neutrik NL4 speakON-type cable connectors. Please refer to RoomMatch loudspeaker documentation for further details.

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.
