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.
