Introduction

LSR4300 Control Center Software is a useful system set-up utility that allows you to ac-

cess any of the functions of your LSR4300 speakers using a computer. Without leaving

your mix position, LSR4300 Control Center Software gives you the ability to modify sys-

tem settings, and also view multiple speaker parameters at once in an easy-to-understand,

user-conﬁgurable graphic display.

In addition, the Control Center Software provides a number of advanced capabilities not

available from the speaker’s front panel or remote control:

• Custom EQ presets can be created and stored in the connected speakers or memory

on disk. EQ settings can also be downloaded from speakers or loaded from disk.

• LF and HF corner frequencies for the EQ can be changed.

• Independent ﬁne speaker Level Trim controls in 0.25 dB increments are provided,

from +3 dB to -10 dB.

• Independent speaker muting and soloing as well as overall system Mute and Dim.

• You can view all ﬁlter and delay settings created for each speaker during RMC cali-

bration. Delay settings can be displayed in feet, meters, or milliseconds.

• Complete system conﬁgurations (including system volume, EQ presets, input selec-

tion, and other settings) can be saved to and loaded from your computer.

In the following pages, we’ll take you through all the necessary procedures to install and

run your LSR Control Center Software, and explain all screen displays and functions.

We’ll

assume that you are already familiar with basic computer operations such as launching

applications and using a mouse to select parameters and navigate through screens and

menus. If not, consult the documentation provided with your computer.

 Throughout this manual, important tips and cautions will be presented like this.

System Requirements

Hard Drive: 100 MB space available

RAM: 128 MB minimum required by this application, over and above the memory re-

quired by other applications running simutaneously.

Operating System: Windows 2000, Windows XP

Introduction - System Requirements

CPU: Pentium III 750 MHz or higher

Installation

1. Insert the CD-ROM in an available CD-ROM drive.

2. From the Start Menu, click RUN.

3. Click BROWSE.

4. Locate the JBL CD containing LSR4300 Control Center Software.

5. Click on the ﬁle named dotnetfx.exe to install the .NET framework required by

the application. An installer will automatically install the ﬁle in the correct location

on your computer.

6. When dotnetfx installation is complete, click on the ﬁle named

LSR4300ControlCenter.exe (lableled a “Setup Launcher” in Windows XP).

An installer will appear. Follow the prompts to complete the installation.

There is no need to restart your computer.

Launching The Software

1. Following installation, a shortcut to the LSR4300 Control Center Software is placed

on your desktop and in your computer’s Start menu.

Installation - Launching The Software

Double-click on the desktop icon (or single-click on the Start menu icon) to launch the

software. See the Reference section below for details about all LSR4300 Control Center

display and menu options.

2. If no speakers are connected to your computer, the LSR4300 Control Center Software

will launch in “Demo” mode, which allows you to explore its features and learn about

LSR4300 capabilities. However, there is no communication between the software and

your speakers in Demo mode, so if you want the software to be fully functional, ﬁrst

make sure that all speakers are networked together properly and that their DIP switches

are correctly set.

(Refer to the LSR4300 Owner’s Manual for more information.) Then use the supplied

USB cable to make a connection between your computer and the LSR4300 speaker

labeled “Left” (LEFT DIP switch up). Finally, press the “Left” speaker Power button

so that the JBL logo is glowing brightly. All networked speakers should power up at the

same time.

 If no LSR4300 Series studio monitors are connected to your computer via the supplied USB

cable, the Control Center Software will automatically start up in Demo mode.

Reference

Main Screen

Whenever you ﬁrst launch the LSR4300 Control Center Software, you will be shown the

main screen, which consists of two sections:

Launching The Software/Reference/Main Screen

• A Room View, which allows you to view settings and make changes to individual

speakers

• A Control Panel, which allows you to make global changes to your entire LSR4300

system.

Room View

The upper area of the Main Screen is the “Room View.” It provides a graphic display

showing all the connected LSR4300 speakers in your network, along with meters for each.

When audio signal is actively passing through the speakers, the meters in the Room View

are active and show the continuous output level of each speaker, same as the meters

on the front panels of the speakers themselves. By clicking on the “Solo” and “Mute”

buttons in each meter, you can selectively solo or mute individual speakers within your

network. Simply click on them a second time to un-solo or un-mute the speaker(s).

 All front-panel buttons on connected LSR4300 speakers and wireless remote control buttons re-

main fully functional even when the Control Center Software is running. Thus, you can, for example,

Solo a speaker from your computer and un-solo it by pressing the speaker’s SOLO button, or vice

versa.

The Room View can show conﬁgurations of up to eight LSR4328P or LSR4326P speak-

ers (and up to two LSR4312SP subwoofers) that range from a single mono speaker on its

own to a full-ﬂedged eight-speaker surround system with two subwoofers. You can view

systems other than the connected system using the Demo mode. (See Options Menu, page

17) The illustration below shows the Room View display for a standard 5.1 surround

system:

Reference - Main Screen/Room View

Rolling the mouse over any speaker in the Room View (sometimes called a “mouse-over”)

and pausing for a moment causes a small informational window to pop up which shows

the designation of the speaker (as set by its rear panel DIP switch) and the amount of de-

lay that has been applied by RMC calibration.* The delay time can be displayed in feet,

meters, or milliseconds. See “Options Tab” below.

The “head” in the Room View is an icon which represents the listener at the mix position

if all speakers are positioned correctly. (See the LSR4300 Owner’s Manual for hints and

tips about speaker positioning.) The appearance of this “listener” as well as the overall

appearance of the Room View can be changed if desired. See “Options Tab” below.

*In LSR4300 ﬁrmware version 1.1, delay for all speakers is set to 0. Delay will be enabled

in future ﬁrmware releases to enhance functionality for surround sound production.

Reference - Room View

Speaker Pop-Up Window

Double-clicking on any speaker in the Room View causes a pop-up window to appear, as

follows:

This window is divided into three sections and provides the following important informa-

tion about each individual speaker:

1. The “Speaker” section presents information about each speaker’s model and ID (i.e.,

Left, Right, Center, Left Surround, Right Surround, etc.)

2. The “Settings” section allows you to Solo and Mute individual speakers and also

enables you to set a “Level Trim” for each speaker, adjustable in 0.25 increments,

from -10 to + 3 dB. Level Trim is a ﬁne control that gives you the ability to manually

compensate for perceived level differences which may occur if your listening position

is not equidistant from all speakers. Other displays in this section show whether the

speaker is carrying the left (“Ch A”) or right (“Ch B”) signal if connected to a digital

signal source and the amount of level adjustment and delay (RMC Trim and RMC

Delay) that has been applied by RMC calibration. For more information about input

selection and RMC calibration, refer to the LSR4300 Owner’s Manual.

3. The “Correction” section shows a simulated graph representing the effect of ﬁlters

applied by RMC calibration. Double-click on the simulated RMC graph to view the

actual NUMERIC RMC settings for all connected speakers. For more information

about RMC calibration, refer to the LSR4300 Owner’s Manual.

Reference - Speaker Pop-Up Window

 Each time you double-click on a different speaker, a new pop-up Speaker window is generated,

but it will be overlaid directly on top of the previous one. To have multiple Speaker pop-up windows

open at the same time, simply move each new one by clicking on the dark gray vertical area at the far

left and dragging it to a new location.

Control Panel

The bottom area of the Main Screen houses the Control Panel, which allows you to make

global changes to all LSR4300 speakers in your network.

Reference - Speaker Pop-Up Window/Control Panel

The Control Panel is divided into the following four sub-panels, from right to left:

1. Volume – enables you to change the overall volume (simply click on the onscreen

dial and drag it), instantly mute the entire system, or DIM (partially reduce) system

volume. (When the system is set to full volume, and DIM is selected, the amount of

attenuation is -12 dB). For best results, click directly on the black indicator of the

knob and apply a circular motion.

 Rapid movement of the onscreen volume control can cause a delayed response in the speak-

er system. This is normal. This delayed response can be alleviated by slowing your movement

of the volume control, or by using the supplied remote control.

System volume settings are stored when using the Save Conﬁguration function in the

Options Menu. Using a calibrated signal and the Save Conﬁguration function, it is

possible to store and recall calibrated volume settings for the system. For more infor-

mation, see Appendix E in the LSR4300 Owner’s Manual.

Clicking on the red, amber and green squares above the volume control reveals a set of

meters that you can position on your desktop. These remain in view even when the LSR

Control Center Software is minimized.
