  • Page 23 4. SUBWOOFER controls – These controls have no function with LSR4328P and LSR4326 monitors; they are used to access various features of the LSR4312SP subwoofer.
  • Page 24: Speaker Placement

    Ideally, they should be placed on suitable speaker stands and well away from boundaries such as walls, ceilings, and large pieces of furniture. The LSR4328P and LSR4326P are equipped with mounting points, to allow wall and ceiling mounting using industry-standard mounting hardware.
  • Page 25: Ac Power Connections

    It also makes it possible for all speakers in the system to be controlled using the supplied wireless remote control and/or LSR4300 Control Center Software. Up to eight LSR4328P or LSR4326P speakers can be interconnected in a single network. HiQnet enables coordinated RMC calibration so sound arriving at the mix position from all speakers is precisely balanced.
  • Page 26 Reference - AC Power Connections/Network Connections and DIP Switch Settings The illustrations below show typical network interconnections for both stereo and surround sound use. Networking interconnections and DIP switch settings for stereo use Networking interconnections and DIP switch settings for surround use At least one LSR4300 monitor in a networked system must have its LEFT DIP switch set to ON.

    Reference - Audio Connections/RMC™ Room Mode Correction To route an incoming AES/EBU two-channel signal to another speaker, use an cable with XLR plugs on both ends to connect the AES/EBU OUT of the first speaker to the AES/EBU IN of the second speaker.
  • Page 29: Performing An Rmc Calibration

    Performing An RMC Calibration To get the benefit of JBL’s revolutionary RMC technology, RMC calibration should be performed The RMC calibration process is simple and easy, taking only a few moments to complete. RMC settings remain in memory even after the speakers are powered down, so typically the process only needs to be performed one time.
  • Page 30 Reference - Performing An RMC Calibration Following are step-by-step instructions for performing an RMC calibration: 1. Make sure all LSR4300 monitors are positioned as intended. 2. Using the mic clip, attach the provided calibration microphone to a mic stand and place the mic at the mix position, oriented vertically, at ear level.
  • Page 31 Reference - Performing An RMC Calibration Do not block the signal coming from any speaker while performing RMC calibration. 5. Each speaker in the system will sequentially emit a reference tone and its meter will show a left-to-right “chase” pattern that indicates the system is calibrating. The RMC procedure produces a fairly loud swept sine wave calibration tone that can surprise you when you hear it for the first time.
  • Page 32: Equalization

    Reference - Performing An RMC Calibration/Equalization The supplied calibration microphone must be connected to perform RMC. If the RMC button is pressed and held for 3 seconds or longer and no mic is connected, the meter display will flash to indicate an error condition, and all RMC settings currently in memory will be erased.
  • Page 33 Reference - Equalization The LSR4328P and LSR4326P provide six factory EQ presets. (A complete listing of all parameters for the factory presets is presented in Appendix A). To recall a preset, press the front panel PRESET button on any networked speaker (it will begin blinking), then use the + or –...

    Under no circumstances should the safety ground wire be removed from the AC power connector. When using balanced sources with the LSR4328P or LSR4326P, either the XLR or T/R/S input connector can be used, since the circuit is common to both. However, both inputs should not be used simultaneously.
  • Page 39 Unbalanced Sources When using unbalanced sources, there are more possibilities to introduce ground loops into a system. The LSR4328P and LSR4326P offer several ways to help alleviate potential problems with unbalanced equipment. While there are only HOT and GROUND/SHIELD connections from unbalanced sources, it is recommended that high quality twisted pair cable be used.
  • Page 40: Digital Audio Connections

    Diagram D details the connections using single conductor shielded cable with a Tip/Ring/ Sleeve or XLR plug for the LSR4328P / LSR4326P input. Single conductor cable should be used as a last resort as it provides the greatest likelihood of problems. The “HOT” (+) signal should be connected to the tip of the Tip/Ring/Sleeve plug.
