Getting Started

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.

LSR6300 specifications

The JBL LSR6300 series of studio monitors is renowned for its exceptional sound quality and precision, making it a preferred choice for both professional studios and passionate audiophiles. With advanced technologies and meticulous engineering, the LSR6300 series delivers a clear, accurate listening experience that is vital for mixing and mastering.

One of the standout features of the JBL LSR6300 is its Image Control Waveguide technology. This innovation ensures not only a wide sweet spot but also excellent off-axis performance. This means that no matter where you are positioned in relation to the speakers, you'll receive a balanced and consistent sound. This technology allows for an even distribution of sound across the audio spectrum, making it easier for engineers to make informed decisions about their mixes.

In terms of drivers, the LSR6300 series boasts high-performance woofers and tweeters that are specifically designed to provide an extended frequency response. The 8-inch woofers replicate low frequencies with impressive depth, while the 1-inch neodymium tweeters deliver crisp high frequencies without introducing distortion. The result is a full-range output that captures the nuances of any audio material.

Another notable characteristic is the room tuning controls on the back of the monitor. These controls enable users to optimize the sound output based on the acoustic environment of their studio. By adjusting the low-frequency and high-frequency settings, you can compensate for any acoustic anomalies in the room, ensuring your mixes translate well to other playback systems.

Furthermore, the LSR6300 is equipped with JBL's patented Slip Stream port design. This rear-firing port minimizes turbulence and enhances low-frequency response. The design ensures that bass notes are rendered with clarity and punch, allowing for a dynamic listening experience without excessive boominess.

The robustness of the LSR6300’s construction is also noteworthy. With a solid enclosure that reduces resonance, the monitors are built to withstand the rigors of daily use. The sleek, professional appearance adds to their appeal in any studio setting.

In conclusion, the JBL LSR6300 series integrates advanced technologies and thoughtful design elements, making it an exceptional tool for audio professionals. With its accurate sound reproduction, flexible room control options, and thoughtful engineering, the LSR6300 continues to set a high standard in the field of studio monitoring.
