2.Power – After connection to an AC power source, press this button to turn the speaker on. If networked together with other speakers, all speakers will turn on simultaneously. Press the button again to return the speaker to a low-power stand-by mode, where the internal amplifiers are turned off and all user functions are deactivated. As shown below, when the speaker is powered on and active, the JBL logo will be brightly lit (see #1 above) and the left-most meter segment will be lit:

3.Meter Display – In combination with front panel buttons, the meter is used to display the current setting and status of the following functions:

•SOLO function (see #4 below)

•Progress of RMC calibration process (see #5 below)

•LF and HF EQ boost and attenuation (see #6, #7 and #8 below)

•EQ preset selection (see #9 below)

•Input source selection (see #10 below)

•Overall system volume (see #11 below)

•Meter and button brightness (see #11 below)

•Error conditions

The meter has 31 three-color segments that can illuminate in green, amber or red. For many of the above operations, all 31 segments light green only. However, when audio signal is being reproduced by the speaker, all three colors are used and the meter is calibrated to indicate the continuous output in decibels (dB) below the speaker’s full output capability. Green LEDs indicate signal 8 dB (or more) below clipping; amber, approximately 7 to 4 dB below clipping; and red, approximately 3 to 0 dB below clipping. The segment furthest to the right (“0”) illuminates red when the input signal is has reached its maximum value (greater than -1.5 dBFS) and causes clipping of the electronics.

The LSR4300 models include protective limiting. Limiting occurs when the output signal exceeds -2 dBFS or the second LED from the right is illuminated (in the LSR4328P) or

-5 dbFS or the fifth LED from the right is illuminated (in the LSR4326P).

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.
