Cause

Lack of network terminators

DIM button on Remote Control is activated

Brightness control is turned down

The Speaker is in SOLO mode.

Input selection is not set to match input source.

Poor connection, defective cable, or source is unstable.

Cable may not be suitable for digital application.

Batteries weak.

Remote is not pointed at the receiver.

Speaker is not connected to power source or fuse is blown.

USB connection and/or Network cables not properly connected.

Missing terminator.

Remedy

Install terminators in first and last speaker.

Press DIM button on remote control to restore full volume. Caution – To prevent sudden jump in volume, lower the system volume setting prior to deactivating DIM control.

Use the brightness control or hold +/- to enter the brightness mode, and push + until you have the brightness level you like.

In a networked system, press SOLO on the speakers that have their SOLO button blinking. If your system is no longer networked and the speaker is still muted, hard reset your loudspeaker.

Make sure your input selection matches the inputs you are using (Analog, S/PDIF, AES/EBU).

Check connections and cables. Confirm you are using suitable cable of proper impedance. If cables and connections are OK, source may be unstable.

Make sure you are using cables per the

S/PDIF and AES/EBU specification as described on page 39 in this manual.

Make sure remote is pointed at the Front Left speaker (the speaker with LEFT DIP switch in the ON position).

Confirm your speaker is connected to an active power source.

Check the fuse. If blown, replace with the spare provided in the fuse holder in the IEC power connector. If speaker fails to power-up please call JBL Customer Service.

Check all network connections to make sure the CAT5 cable is inserted all the way into each jack.

Make sure you have two network terminators installed in your system so that all RJ485 jacks are in use. Confirm the USB cable from your computer is connected to the front left speaker (the speaker with LEFT DIP switch in the ON position).

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.
