LSR6328P Biamplified Studio Monitor System

Boundary Compensation

Switch 5 introduces a low frequency shelf roll-off of -1.5 dB, while Switch 6 introduces a low frequency shelf rolloff of -3 dB. Engaging both switches will produce a low frequency shelf rolloff of -4.5 dB. These functions are known as Boundary Compensation and are used to adjust for the build-up of low frequencies that accompany the placement of loudspeakers near walls or corners, or work surfaces.

The changes in low frequency response using Switches 4, 5, and 6 are shown in Figure F.

High Frequency Adjustments

Switch 7 introduces a high frequency response shelf cut of 1 dB above 2 kHz. This may be used if the room is fairly live, or if you are fairly close to the loudspeakers. Switch 8 introduces a high frequency response shelf boost of 1 dB above 2 kHz. This may be used if the room is extremely dead. The changes in high frequency response using Switches 7 and 8 are shown below in Figure G:

A single LED indicator is located on the front of the LSR 6328P. In normal operation, this LED will be GREEN. At the onset of clipping in either the low or high frequency amplifier, the LED will flash RED. Continuous flashing of the red LED indicates that levels should be reduced. Caution: The LSR6328P is capable of producing extremely high sound pressure levels. To avoid hearing damage, caution should be exercised.

RMC Equalization

There are three screwdriver adjustable controls on the rear panel of the 6328P indicated RMC. The term RMC stands for Room Mode Correction, which consists of a single section cut-only parametric equalizer that can be adjusted in frequency, width (Q) of cut, and the amount of cut. It is used to reduce the magnitude of any dominant low frequency peak in response due to standing waves at the listen- ing position. Details of Room Mode Correction are presented in the user guide included with the RMC Calibration Kit.

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.
