JBL LSR6300 - Manual (Page 6)

Getting Started
6
The LSR6312SP can be placed in either a vertical or horizontal orientation. More important than orientation is the physical position in
the room.
Angling toward the listening position: The LSR6300-Series monitors should be angled to directly face the listener. The center of the high
frequency transducer should be on-axis with the ear level of the listener. Ideally, full-range speakers should be placed on suitable
speaker stands away from boundaries. The LSR6312SP Subwoofer can be located on the floor with its woofer cone on the same plane
as the woofer cones of the full-range speakers. Alternately, the Subwoofer performance can benefit from placement close to a wall or
corner. LSR6328P and LSR6312SP models include Boundary Compensation settings when speakers are placed in close proximity to
walls, corners and work surfaces.
Audio Connections
Refer to individual model-specific instructions.
Power Connections
The LSR6328P can be used with multiple AC supply voltages around the world. It will automatically adjust for operation from 100 to
240 VAC with no intervention by the user. The ground terminal of the IEC plug is required by wiring codes and regulations. It must
always be connected to the electrical installation safety ground. The LSR6300-Series units have carefully designed internal grounding
and balanced inputs and outputs to reduce the possibility of ground loops (hum). If hum occurs, see Appendix B for suggested audio
signal wiring, system grounding hints and other preventive measures. The LSR6312SP is set at the factory for use with either 100V-
125V or 200V-250V. Voltage is not field selectable.
Making Sound
After connections are made, the next step is to power up all equipment before powering up active LSR6300 speakers and external
amplifiers. Reduce the level of the monitor outputs of your console or preamp to minimum and turn on the powered speakers and the
amplifiers. There is a small delay with the power-up of the LSR6328P and LSR6312SP to accommodate for clicks and thumps from
upstream equipment. When the Green LED on the front panel turns on, the units are ready to go. Slowly advance the gain of the console
to feed the monitoring system to suitable listening level, and enjoy.
