Introduction
Congratulations on your purchase of JBL LSR4300 Series Studio Monitors, the most advanced
loudspeaker system ever developed for critical listening.
We know that very few people read owner’s manuals from cover to cover, so we’ve organized
this one to make it easy to find the information you need.
The Features section on the next page provides a brief overview of the exceptional features of
the LSR4300 Series. It’s followed by a QuickStart section, which will get you up and
running in a matter of minutes.
Once you’ve got your LSR4300 system powered up and delivering sound, you should turn to
the Reference section, which describes every feature and function of the LSR4300 in detail.
Finally, we’ve included a number of technical appendices and specifications at the end of this
manual.
Note that this manual covers the model LSR4328P and LSR4326P Studio Monitors. Separate
owner’s manuals are provided for the model LSR4312SP Subwoofer and for the LSR4300
Control Center software.

Features
The LSR4300 Series combines stunning sound and legendary JBL design with innovative new
technologies. The end result is a product that is nothing short of revolutionary – a monitoring
system suitable for use in the most demanding music, broadcast, and postproduction
applications.
RMC™ Room Mode Correction
The biggest challenge for anyone producing audio is creating a mix that sounds great on all
playback systems. If you think of a monitoring system as a kind of “lens” through which you
hear sound, the object is to have the lens be crystal-clear and transparent so that it imparts no
coloration whatsoever to the signal being played back. However, every loudspeaker system,
no matter how well designed, interacts with the room in which it is installed. Lack of correct
acoustic treatment (or, worse yet, lack of any treatment at all) can result in anomalies such as
resonant frequencies and low-frequency “standing waves” – the aural equivalent to the lens
being “smeared.” Trying to create a mix in such an environment can be as frustrating and
difficult as trying to paint a masterpiece while blindfolded.
JBL’s exclusive second generation RMC™ Room Mode Correction technology is designed to
solve the problem. A powerful onboard computer in each LSR4300 Series monitor
automatically analyzes the frequency response of your room and compensates for low
frequency inaccuracies in the listening space by precisely inserting filters so that low
frequency signals arrive at the mix position with the intended frequency response. In effect,
the LSR4300 Series goes “beyond accurate,” allowing you to eliminate the guess-work and
create reliable mixes that translate to any environment. Additionally, the RMC system trims
the level of each speaker to compensate for differences in placement relative to the mix
position, ensuring balanced mixes.

HiQnet™ Networking
The LSR4300 Series also incorporates the new Harman HiQnet™ protocol that networks all
the speakers in a system together and allows full control from the provided wireless remote
control or from any computer via a standard USB connection and LSR4300 Control Center
Software. With the push of a button or the click of a mouse you can change the system level,
choose from any of three different inputs (one analog and two digital), mute and solo
individual speakers, and make low and high frequency EQ adjustments.
LSR Linear Spatial Reference Design
The LSR4300 builds on the Linear Spatial Reference technology that has made our LSR6300
Series of studio monitors so popular in recording, broadcast, and postproduction facilities
worldwide. The exact geometry of the wave guide, the interaction of the woofer and tweeter,
and the final assembly of the injection-molded parts has been redesigned from the ground up
to provide accurate off-axis as well as on-axis listening, within a window of +/-30 degrees
horizontal, +/- 15 degrees vertical. Attention to these critical aspects results in neutral mid and
high frequency response at the mix position and a sound which is smooth and accurate in a
wide variety of acoustic spaces.
Surround Smart
The LSR4300 Series is ideal for surround sound use. Up to eight main speakers – any
combination of LSR4326 6-inch and LSR4328 8-inch models – and up to two LSR4312SP
subwoofers can be easily configured for LCRS, 5.1, 6.1, 7.1 SDDS and larger mixing and
monitoring applications.
Once all LSR4300 monitors are in place, RMC and HiQNet automatically aligns the entire
system, setting relative volume so that the sound from all channels is balanced when it arrives
at the mix position. The end result is precise imaging regardless of each monitor’s actual
physical placement.
In addition, the ability to centrally control the volume of all the speakers (via the supplied
wireless remote control or LSR4300 Control Center software) is particularly useful in
surround sound applications where the recording system does not provide a multi-channel
monitor volume control, or where adjustable volume is not available when using the
mixing system’s digital outputs. Similarly, the ability to selectively mute or solo channels and
to remotely switch between three digital and analog input sources enhances system capabilities
by allowing you to monitor not only the main recording system, but also any two additional
connected sources such as DVD and CD players, multi-channel processors and encode-decode
units. This alleviates the need to purchase additional outboard monitoring hardware.
Selectable Inputs
In this age of digital workstations and control surfaces, it isn’t enough to simply provide an
input jack. The LSR4300 offers three separate inputs: stereo high-resolution 96 kHz AES/
EBU and S/PDIF digital inputs, as well as dual balanced analog XLR and ¼-inch inputs with
selectable +4dBu / -10dBV sensitivity. This allows it to accommodate a wide range of input
sources, including digital workstations, CD players, DVD players, and multi-channel proces-
sors. What’s more, you can easily select between inputs with the push of a single button (on
either the front panel or the wireless remote) or click of a mouse (via an attached computer and
the included LSR4300 Control Center software).

Onboard Bi-amplification
LSR4300 Series monitors are self-powered, eliminating the need for external amplifiers.
Perfectly matched bi-amplification is provided onboard, with 150 watts of power for the
woofer and 70 watts for the high frequency transducer.
Other Features
• Custom designed transducers specially engineered to deliver clean, crisp sound. The
LSR4328P model features an 8-inch low frequency woofer, while the LSR4326P
model offers a 6.25-inch woofer, both coupled with a 1-inch soft-dome high frequency
transducer. All transducers are self-shielded, with Neodymium motor structures for
exceptional transient response and superb power handling.
• Advanced front-panel user interface allows control of system functions such as
volume, input selection, user EQ and EQ presets, RMC calibration and bypass,
individual speaker solo, and brightness level of the meter and buttons.
• Front panel meters show continuous output levels in dBFS to serve as a visual
reference of the speaker’s contribution when measured at the mix position.
• Integrated mounting points allow wall mounting of speakers when space limitations
prohibit the use of speaker stands.
• Built-in side handles make positioning and transporting of speakers easier.

Quick Start
Each LSR4300 speaker includes:
• One speaker
• CAT5 networking cable
• AC power cord
• This owner’s manual
The LSR4326/PAK and the LSR4328P/PAK include:
• Two speakers, each with the above items
• LSR4300 Accessory Kit containing:
o Calibration microphone and mic clip
o Infrared wireless remote control
o LSR4300 Control Center Software
o 16-foot USB Cable
o Two network terminators
o Two AAA Batteries
Here are simple step-by-step instructions to get you up and running quickly:
1. Unpack the speakers. To avoid damage to the speaker elements, open the top of the box,
keep the Styrofoam end cap on, and roll the box upside down. The box can then be slipped
off. (This also works in reverse for repacking the units.)
Be sure to not grasp the monitors from the front. A stray hand or finger can cause
damage to the high frequency transducer that is located near the top of the cabinet on the
front baffle.
2. Position each speaker in the room. (See page 20 in this manual for speaker
placement tips.)

LSR4300 Rear Panel
3. Connect each speaker to a suitable power source using the supplied AC power cable.
(See page 23 in this manual for more information.)
4. Connect the speakers together in any order using the supplied CAT5 cable. Plug one end
of the cable into either of the two HiQnet ports on one speaker and the other end into a
HiQnet port on another speaker until all speakers are connected. Connect the two supplied
ethernet terminators to the first and last speakers in the chain. (See page 21 in this manual
for more information on networking your LSR4300 monitors.)
5. Set the Network ID DIP switch on the rear panel of each speaker so that it corresponds to
the channel for which the speaker is to be used. For example, place the DIP switch labeled
LEFT in the up (ON) position for the speaker reproducing the left channel, and place the
DIP switch labeled RIGHT in the up (ON) position for the speaker reproducing the right
channel. (See page 22 in this manual for more information.)
Make sure that one, and only one, DIP switch is placed in the up (ON) position for each
speaker. One speaker in the system must have the LEFT DIP switch set to the ON position.
6. Make all required audio connections to the rear panel of your monitors. Both the
LSR4328P and LSR4326P models are both able to accommodate one analog and two
digital input signals. (See page 23 in this manual for more information on audio
connections.)
a. If you are connecting an analog signal (i.e. from the line level analog outputs of a
mixing console, workstation, CD player, or DVD player), use appropriate cabling
to make a connection between the device and either the rear panel Analog XLR
connector or ¼� connector, then set the rear panel Input Sensitivity switch to
