Reference - Equalization

The LSR4328P and LSR4326P provide six factory EQ presets. (A complete listing of all parameters for the factory presets is presented in Appendix A). To recall a preset, press the front panel PRESET button on any networked speaker (it will begin blinking), then use the

+or – buttons to select the desired preset. Preset 1 is indicated by the left-most block of five LEDs lighting green, and each successive block of five LEDs indicates the next preset. Thus, for example, if you see the right-most block of five LEDs lit, that is an indication that you are calling up Preset 6. If no preset is selected while the PRESET button is flashing (for about 3 seconds) the system will return to its current settings. See page 31 in this manual for illustrations showing the LED display for each preset.

Preset 0 is a special case. Indicated by the lighting of a single LED on either side of the center (-15) mark, this is the user memory area, which always contains a copy of the last recalled preset. Changes made to preset 0 remain in memory even after the LSR4300 is powered down; however, they are lost when one of the six factory presets is recalled. If this preset is selected prior to the time-out of the preset function, no change is made to the current settings. LSR4300 Control Center software allows the creation and storage of custom user equalization curves, which can then be loaded into memory, overwriting any of the factory presets. For more information, see the LSR4300 Control Center owner’s manual. Additionally, the Control Center Software allows you to select the frequency of EQ boost

or attenuation.

Whenever a preset is selected, the LF and HF buttons will illuminate to indicate whether the currently selected preset contains LF and/or HF boost or cut (the button corresponding to the most recently changed band will flash). The preset becomes active when the PRESET button stops flashing (after 3 seconds). If no preset is selected, the system will return to its current settings. If preset “0” is selected before the 3 second time-out of the function, no change is made to the EQ settings.

Equalization presets can be stored in memory or to disk with the use of the supplied LSR4300 Control Center software. Changes made to a preset are held in memory even when the LSR4300 is powered down; however, without the use of the software, any changes made will be lost when another preset is called up.

A preset can be deactivated by pressing the EQ ON button until the light goes out, or by manually setting both the LF and HF values to 0 dB.

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.
