[. . . ] LSR6325P ed Studio Monitor System Owner's Manual Important Safety Instructions The IEC fuse symbol pictured at the left represents an approved, user replaceable fuse. When replacing a fuse, make sure to replace with only the correct type and fuse rating. Read lnstructions - Before operating your new JBL product, please read all safety and operating instructions. Keep these instructions - For future reference and troubleshooting purposes, retain these instructions. [. . . ] The RMC circuit in the LSR6312SP and the included RMC Calibration Kit allow you to identify and compensate for troublesome low frequency standing waves. The result is clear extended bass response at the mix position in any size room. Set Up Unpacking ­ Caution: The high-frequency transducer is unprotected and can be damaged if touched while unpacking the speaker. An easy way to safely unpack your monitors is to open the top of the box, keep the ller piece on and roll the box upside down. This also works in reverse for repacking the system. Placement ­ Speaker Placement Listening Distance: In a stereo close-field application the speaker is typically placed 1 to 1. 5 meters (3-5 feet) from the listening position. In mid- eld or surround sound applications, 2-3 meters is typical. The field in a stereo listening application is optimized by arranging the speakers to form an equilateral triangle where the distance between the two speakers equals the distance of each speaker to the listening position. Horizontal Placement: The LSR6325P system is designed for vertical orientation which provides broad lateral dispersion and controlled vertical dispersion to optimize the size of the listening window and minimize reflections off the work surface and the ceiling. Horizontal placement will limit the size of the listening window and increase reflections which can result in cancellation at high frequencies. Angling towards the listening position: The LSR6325P should be angled so the center of the high frequency transducer points directly at the listener's ears. 6 CBCBCBBB CB Audio Connections The LSR6325P includes one XLR and one RCA connector to accommodate a wide range of signal levels and balanced or unbalanced configurations. The XLR input is nominal +4 dBu sensitivity and the RCA input is -10 dBV. Audio Level Adjustment The audio level sensitivity of the LSR6325P can be adjusted to accommodate a wide range of applications. Audio systems typically send signal with nominal level of either +4 dBu or -10 dBV. These are referred to as professional and semi professional levels, respectively. The nominal input level of the LSR6325P XLR input is +4 dBu and -10 dBV for the RCA input. A nominal level to these inputs will produce an output of 96 dB SPL at a distance of 1 meter in an anechoic environment. This allow the user to get a good match when using either professional or semi professional equipment. If less sensitivity is needed the front panel volume control can be adjusted down. When set in the 12:00 position, the front panel volume control attenuates the signal by 9 dB. Frequency Response Adjustments Four DIP switches located in a recess on the rear-panel of the LSR6325P allow the user to adjust frequency response to compensate for placement, program material and personal preference. To activate the associated switch function, set the switch in the UP position ­ so the switch is closer the JBL logo on the rear of the speaker. The LSR6325P is shipped with all switches in the DOWN position so the switches are at the setting farthest away from the JBL logo. 8 Switch 3 boosts the high frequency response by 1. 5 dB above 2. 3 kHz when set to the UP position. This position can be used if the room is extremely dead, or you want to hear more high frequency from the speaker to assist you in creating "warmer" mixes.
