Audio Connections

The LSR4328P and LSR4326P speakers are equipped to accommodate a range of analog and digital signal input sources. You can connect two digital sources and one analog source to each speaker and switch between them using front panel controls, or the wireless remote control and/or LSR4300 Control Center software.

Analog Connections

Positive voltage to Pin 2 of the XLR connector or the tip of the ¼″ jack will produce a forward motion in the speaker cone. See Appendix C in this manual for wiring diagrams. Analog signal sources must be connected to either the rear panel XLR or ¼″ connector.

Do not connect analog signal to both the XLR and ¼″ inputs; use one or the other.

The LSR4300 provides switchable input sensitivity between +4 dBu and -10 dBV, as determined by the two-position Input Sensitivity switch on the rear panel.

When the sensitivity is set for +4 dBu, an input signal equal to +4 dBu will produce a system output level of 94 dB SPL at a distance of one meter. Likewise, a setting of –10 dBV will cause an input level of –10 dBV to attain the output acoustic level of 94 dB SPL at a distance of one meter. Use of the front panel Volume control (that is, pressing the +/- button when no button is flashing) allows further level matching.

Incoming analog signal is internally routed to the LSR4300’s high resolution 96kHz, 24-bit, oversampling A/D converters.

Digital Connections

Connect digital sources in AES/EBU format to the rear panel XLR digital input connector and those in S/PDIF format to the rear panel phono digital input connector. The following sample rates are supported: 96kHz, 88.2kHz, 48kHz, 44.1kHz, 32kHz, with word lengths of up to 24 Bits.

AES/EBU and S/PDIF digital audio is transmitted as a two-channel pair on a single cable. Each LSR4300 speaker can reproduce only one channel at a time: either the left “A” channel or the right “B” channel. The channel reproduced is determined by the speaker’s DIP switch settings, as per the chart below. For example, when the leftmost (“Left”) DIP switch is ON, the speaker will reproduce Channel A of the incoming stereo digital data stream.

When the following DIP Switch is 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.
