Wiring Requirements

For optimum performance, some attention to wiring details now can reduce system degradation later. The cabling recommendations given below follow standard wiring practice for differential inputs.

Balanced Sources: The best way to run your system is balanced, where both "HOT" (+) and "COLD" (-) signals are supplied from the source along with a GROUND/SHIELD. These are typically carried on 2 conductor shielded cables with XLR connectors on both ends. Alternatively, connectors with Tip, Ring and Sleeve (T/R/S) jacks can be used. Whenever possible, the cable shield should not be con- nected to any signal pin, but left to perform a cable shielding function only. Note: Under no circumstances should the safety ground wire be removed from the AC power connector.

When using balanced sources with the LSR6328P, either the XLR or T/R/S input of the Neutrik Combi connector can be used, since the circuit is common to both. The difference between the two is that the T/R/S input is generally set for a nominal -10 dBV input and the XLR input is generally set for +4 dBu.

For balanced signals, the HOT (+) signal from your source should be connected to the tip of the T/R/S connector or Pin 2 of the XLR input as shown in Diagram A. The "COLD" (-) signal should be connected to Pin 3 of the XLR or the "Ring" of the T/R/S connector. To avoid ground loops, connect the SHIELD at the source end but not at the LSR input.

Unbalanced Sources: When using unbalanced sources, there are more possibilities to introduce ground loops into a system. The LSR6328P and LSR6312SP offer several ways to help alleviate potential problems with unbalanced equipment.

While there are only HOT and GROUND/SHIELD connections from unbalanced sources, it is recommended that high quality twisted pair cable be used. Diagram B shows an unbalanced source connected to the balanced XLR input of the LSR monitor using twisted pair cable. Note that the shield is connected to the GROUND/SHIELD connector at the LSR input, but not at the source. This reduces the likelihood of introducing a ground loop into the system.

When using unbalanced signals with an LSR6328P, it is recom-

mended to use a 1/4" Tip/Ring/Sleeve connections. Diagram C shows when using the 1/4" Tip/Ring/Sleeve connection, the GROUND should be tied to the source -- not the sleeve -- of the LSR input for optimum performance.

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.
