I see an unusual light pattern on my JBL LSR 4300 speakers: the “Analog,” “AES/EBU,” and “CHB” LED’s are lit up. What does this mean?

This light pattern indicates an error. You can look up these errors in Appendix F of the LSR User’s Manual.

This particular error is Brown Out Condition, which is caused when the supply voltage level drops below the required voltage.

To remedy this, disconnect and reconnect the power cord. Frequent occurance of this problem indicates inadequate supply voltage, and should be corrected with an exterior power conditioning/voltage regulating device.
