I see an unusual light pattern on my JBL LSR 4300 speakers: the RMC button is blinking and the meter is lighting sequentially from right to left. 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 No Mic Found, which is caused if the RMC mic is not connected during RMC calibration.
To remedy this, press [RMC] to exit RMC mode. Connect the mic, then press and hold [RMC] to calibrate.
