Introduction Congratulation on your purchase of LSR6300 Studio Monitors. All LSR6300 models incorporate proprietary and patented JBL transducer and network technologies., to provide ultra-accurate response, and exceptional SPL capability. Because production rooms are acousti- cally less-than-perfect, JBL has incoporated technologies in the LSR6300 Studio Monitors to overcome problems in the room. The result: clear accurate sound at the listening position in any room. LSR6300 Features to Overcome

Getting Started Unpacking: When removing the systems from their packaging, it is important not to grasp the units from the front. Because the high frequency device is located near the top of the cabinet on the front baffle, a stray hand or finger can cause damage. The best way to safely unpack your monitors is to open the top of the box, keep the cardboard filler piece on, and roll the box upside down. The box can then be slipped off. This also works in reverse for repacking the units. Placement

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

LSR6328P Biamplified Studio Monitor System AC Power Connections The LSR6328P can accommodate power from 100 to 250 VAC 50/60 Hz by way of an autosensing power supply. This requires no atten- tion on the part of the user. The ground terminal of the IEC plug is required by wiring codes and regulations. It must always be connected to the electrical installa- tion safety ground. The LSR6300 Series models have carefully designed internal grounding and balanced inputs and outputs to reduce the possibi

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 res

LSR6332 Studio Monitor System The LSR6332 Linear Spatial Reference Studio Monitor combines JBL's latest in transducer and technology with recent breakthroughs in system design to provide a more accurate studio reference in a variety of pro- duction environments. The neodymium 12" woofer is based on JBL's patented Neodymium Differential Drive NDD™ technology. With the Neodymium magnet structure and dual drive coils, power compression is kept to a minimum to reduce spectral shift as power levels i

LSR6332 Studio Monitor System This adjustment is accomplished via the barrier strip on the back of the enclosure located above the dual pair of 5-way binding posts. Moving the link between the 0 and -1 dB positions will change the high frequency drive level. Please note that the loudspeaker should be disconnected from the amplifier during this procedure for safety of the system. Changing Mid/High Orientation The LSR6332 is normally used in the horizontal position with the mid- and high-frequency

LSR6312SP Powered Subwoofer System The LSR6312SP Active Subwoofer consists of a Neodymium Differential Drive NDD™ 12" neodymium woofer integrated with a powerful 260 watt continuous power output amplifier. The active drive circuitry has been developed to maximize the acoustic output power while maintaining overall low distortion and excellent transient performance. The enclosure is manufactured with a molded baffle and rigidly braced MDF enclosure for low resonance and minimal box loss. The Line

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 fi

Appendix A 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, c

Appendex A Diagram D details the connections using single conductor shielded cable with a Tip/Ring/Sleeve plug for the 6328P input. Single con- ductor cable should be used as a last resort as it provides the greatest likelihood of problems. The "HOT" (+) signal should be connect- ed to the tip of the Tip/Ring/Sleeve plug. The GROUND should be attached to the Ring of the Tip/Ring/Sleeve plug at the 6328P input. Unbalanced Source LSR Input Diagram D Tip Pin 2 ++ (Tip) Pin 3 - (Ring) Pin 1 Sleeve (
