3.4 Optional OWS 4 Zone Splitter Board fits 4580 Brackets - SUB999
Figure 5 SUB999 Board Layout
The OWS main control board supports only a single zone speaker output. The optional SUB999, 4 Zone
Splitter Board, allows for the speaker output from the main board to split into 4 individual speaker circuits.
Each of the four speaker outputs is individually monitored for short and open circuit fault. The optional
SUB999 allows the PA to be only controlled over selected speaker zones
12
(not used in the standard
standalone OWS).
There are 4 status LED indicators on each SUB999. When lit, they indicate which zones are being
activated. These LEDs mimic the PA selection Display Board on SUB863 (when used) as shown in
Table 6.
Up to 12 boards (SUB999) can be daisy-chained to provide a maximum of 48 speaker zones
only when
SUB860 software revision 2.0 is used.
