LSR6312SP Powered Subwoofer System

There are several ways to connect the LSR6312SP in a monitoring system including stereo, multi-channel for- mats such as Dolby ProLogic, AC-3, DTS, and others.

The bass management system in the LSR6312SP pro- vides the flexibility to switch between configurations.

In a Stereo Configuration, it is typical to feed the LSR6312SP with the left and right channels and take the left and right outputs from the LSR6312SP and feed them to the satellites. The high pass filters on the sub- woofer outputs remove the low frequency signal below 85 Hz from the satellites. This signal is then redirected to the subwoofer.

The Dolby ProLogic format uses a similar connection scheme to the one above. The left, center and right channels route to the left, center and right inputs of the LSR6312SP and through the respective outputs to the satellites. Signals below 85 Hz are filtered out of the satellites and sent to the subwoofer.

Other multichannel formats such as Dolby AC-3 and DTS may include six discrete channels, left, center, right, left surround, right surround and subwoofer. These are termed 5.1 for the five main channels and the dedicated "point-one" subwoofer channel, which is also called the low frequency effects, or LFE channel. Not all program material makes use of all channels, and mixing engi- neers have the discretion to use - or not use - the subwoofer channel.

The Left, Center and Right channels are routed to the respective LSR6312SP inputs and on to the front channel LCR speakers. The LFE channel is sent directly to the Direct input of the LSR6312P. When not in bypass mode, the system operates as the stereo and Prologic setups previously described. All subwoofer information is derived from the front channels and the Direct subwoofer input. When a con- tact closure occurs, the high pass filtering is bypassed to the satellites and the satellites then receive the original full range signal. The sub-woofer feed from the Direct LFE input remains active.

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.
