Configuration not optimal/not recommended
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

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.
