Quick Start

8.Power up your signal source, then press the front panel POWER button on any speaker. All speakers in the system will power on (the JBL Logo will go from dimly to brightly lit.)

To avoid “thumps” which can damage your speakers, always power up the signal source FIRST and your LSR4300 monitors LAST.

9.Set the initial speaker volume by pressing the + / - controls on any speaker. All speakers in the system will go to the designated volume. As the volume is increased, additional LEDs light. We recommend beginning with a modest volume setting, so that only the first ten LEDs or so (up to the “-20”) mark are lit.

10.Play a signal source and adjust the final speaker volume to a comfortable listening level by pressing the + / - controls on any speaker.

11.If your LSR4300 system is brand new, the RMC button on the front panel of all speakers will be lit, indicating that Room Mode Correction has not yet been performed. To calibrate your speakers with RMC, begin by attaching the provided calibration microphone to a mic stand and place the mic at the mix position, oriented vertically. Then connect the microphone to the Left speaker’s RMC MIC rear panel input.

To perform an RMC analysis, the calibration microphone must be connected to the speaker designated as “Left” (LEFT DIP switch up).

12.Press and hold the RMC button on any speaker, then walk to a spot in the room where you are not blocking the path between the microphone and any speaker. Each speaker will emit a reference tone in turn and its meter will show a left-to-right “chase” pattern that indicates the system is calibrating. When the “chase” pattern on the meters stops, the process is complete. You can compare the effects of RMC with the uncorrected response by pressing the RMC button on the front panel of any speaker. When the button is lit, RMC correction is being bypassed and you hear the uncorrected response; when the RMC button is unlit, the RMC is active and compensating for any acoustic deficiencies in your listening environment. (See page 25 in this manual for a step-by-step description of the RMC calibration procedure.)

The RMC procedure produces a fairly loud swept sine wave calibration tone that can surprise you when you hear it for the first time. After pressing the RMC button, move away from the speaker. There is a five second delay prior to the sounding of the calibration tone.

13.Place the provided batteries in the wireless remote control, and, if you want to

establish computer control over your LSR4300 system, make a USB connection between your computer and the LEFT speaker and then install the provided LSR4300 Control Center Software.

14.Finally, put on some good music to listen to and take a few moments to read the rest of this manual to acquaint yourself with all the features of your JBL LSR4300 system. Enjoy!

LSR4326P, LSR4328P specifications

The JBL LSR4328P and LSR4326P studio monitors are part of JBL’s acclaimed professional audio lineup, known for their precision, clarity, and innovative technology. Designed for critical listening environments, these monitors are ideal for music production, broadcast, and post-production applications.

One of the standout features of the LSR4328P is its 28/26-watt bi-amplified system, which delivers powerful and detailed sound reproduction. The LSR4328P has an 8-inch woofer and a 1-inch titanium tweeter, while the LSR4326P is equipped with a 6.5-inch woofer and the same 1-inch titanium tweeter. This dual-cone design ensures that both low and high frequencies are reproduced accurately, making them suitable for a variety of musical genres.

Both models include JBL’s patented Image Control Waveguide technology. This unique design enhances the monitors’ stereo imaging and provides a wider sweet spot, allowing listeners to experience a more immersive soundstage. With precise positioning of the tweeter, the waveguide helps achieve a smooth frequency response, which is essential for accurate mixing and mastering.

Another notable feature is the integrated room control EQ, which allows users to tailor the monitors to their specific acoustic environment. This helps to counteract the effects of room acoustics, ensuring that the sound remains consistent and accurate regardless of the listening environment. Additionally, both models support various input options, including balanced XLR and TRS connections, making them versatile for different studio setups.

The LSR4328P and LSR4326P also incorporate advanced DSP technology for refined performance. This includes precise limiting and crossover functionalities that ensure optimal power distribution between the woofer and tweeter. The result is a balanced sound that does not compromise on detail or frequency response.

In terms of build quality, both models feature a sleek, professional design with a durable cabinet that minimizes resonance and distortion. They are equipped with a front-mounted volume control, making it easy to adjust levels during sessions. Together, the JBL LSR4328P and LSR4326P blend state-of-the-art technology with user-friendly features, establishing them as essential tools for professionals seeking high-fidelity sound in their recordings.
