system digital controller
1 Bose 1800-VI power amplifier
2 2x broadside bass array brackets (top and bottom)
2 MB4 modular bass loudspeakers
Spacing:
In order to effectively create the MB4 2x endfire bass
array, each unit must be spaced 45" (114.3 cm) on
center from each other. This is shown in the illustra-
tion above. IF THE UNITS ARE NOT SPACED
PROPERLY THE BASS ARRAY WILL NOT WORK.
Note: All EQ and delay settings are already set in the
PANARAY system digital controller. In order for the
bass array to work, you must connect the MB4 units
to the appropriate outputs on the controller and apply
the proper spacing. The output assignments are list-
ed to the right.
