LSR6328P Biamplified Studio Monitor System

The LSR6328P Bi-amplified Studio Monitor sets the standard for exceptional performance in near field design. With a combination of advanced transducer engineering and powerful drive electronics, the LSR6328P meets the professional’s requirement for accuracy and high dynamic range on the most demanding sessions.

The addition of JBL RMC™ Room Mode Correction circuit and boundary compesnation ensures accurate low fre- quency response at the listening position, free of the spectral shift caused by room modes and the effect of boundaries.

The 8" woofer is based on JBL's patented Differential Drive® technology. With dual 1.5" drive coils, power compression is kept to a minimum to reduce spectral shift as power levels increase. An added third coil between the drive coils acts as a dynamic brake to limit excess excursion and reduces audible distortion at maximum levels. The cone is made of a carbon fiber composite forming a rigid pis- ton and is supported by a soft butyl rubber surround.

The high frequency device is a 1" composite diaphragm integrated with an Elliptical Oblate Spheroidal (EOS) Waveguide with 100° by 60° dispersion, which is critical to the smooth spatial response required in today's working environments. The magnetically sheilding of the HF transducer reduces interference when used in close proximity to CRT video and computer monitors. This custom power supply eliminates all tonal-artifacts produced by the speaker when idling.

Audio Connections

LSR6328P Audio Connections: The LSR6328P comes with a Neutrik "Combi" connector that accommodates either an XLR or 1/4" con-

nector in either balanced or unbalanced configurations. The system has switchable input sensitivity: +4 dBu, +8 dBu, and -10 dBV. These sensitivities are determined by adjusting the DIP switches according to the legend shown in Figure C. When the sensitivity is set for, say, +4 dBu, an input signal equal to +4 dBu will produce a system output level of 96 dB SPL at a distance of one meter. Likewise, settings of +8 dBu and -10 dBV will cause those input levels to attain the output acoustic level of 96 dB SPL.

An additional switch allows user-adjustable input sensitivity via a screwdriver control on the back panel. See Section 4 for additional information on level control and gain matching. Positive voltage to Pin 2 of the XLR or the tip of the 1/4" jack will produce a forward motion in the low frequency cone. Shown below in Figures C and D are views of the rear electronics panel on the LSR6328P and a sig- nal flow diagram for the system. We recommend that you study these drawings in detail.

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.
