To avoid “thumps” which can damage your speakers and subwoofers, always power up the signal source
FIRST and your LSR4300 system LAST.
10. Set the initial speaker volume by pressing the + / - controls on the subwoofer or on any speaker. All
speakers in the system will go to the designated volume. As the volume is increased, additional LEDs
light. We recommend beginning with a modest volume setting, so that only the fi rst ten LEDs or so (up to
the “-20”) mark are lit.
11. Play the signal source and adjust the overall volume to a comfortable listening level by pressing the
+ / - controls on any speaker.
12. If your LSR4300 system is brand new, the RMC button on the front panel of all
speakers and subwoofers will be lit, indicating that Room Mode Correction has not yet been performed.
For more information about calibrating your system with RMC, see page 32 in this manual.
13. Finally, put on some good music to listen to and take a few moments to read the rest of this manual to
acquaint yourself with all the features of your JBL LSR4312SP subwoofer.
Enjoy!
