Chapter 8: Troubleshooting

Series SPB Audio Boosters Manual, Revision A
8-2

When there are no trouble conditions detected on the Series SPB Audio Booster, the AC LED
and DC LED indicator always remains ON and the TROUBLE LED indicator always remains
OFF. When a trouble condition is detected, the AC LED indicator remains ON and the
TROUBLE LED indicator always remains ON.

Figures 8-1 and 8-2 show the location of all trouble location LED indicators within the Series
SPB Audio Booster panels. Table 8-1 cross-references the trouble location LED indicators on the
mother board to the proper troubleshooting procedure.

NOTE: When D73 TBL LED indicator is ON, indicating a panel Trouble, at least one of the other

yellow LED indicators is also ON, indicating the trouble location.
