DISC JBL LSR4328P Active Studio Monitors (Each)

Full Description

The biggest challenge for anyone producing audio is creating a mix that sounds great on all playback systems. If you think of a monitoring system as a kind of "lens" through which you hear sound, the object is to have the lens be crystal-clear and transparent so that it imparts no coloration whatsoever to the signal being played back. However, every loudspeaker system, no matter how well designed, interacts with the room in which it is installed. Lack of correct acoustic treatment (or, worse yet, lack of any treatment at all) can result in anomalies such as resonant frequencies and low-frequency "standing waves" - the aural equivalent to the lens being "smeared." Trying to create a mix in such an environment can be as frustrating and diffcult as trying to paint a masterpiece while blindfolded.

JBL's exclusive second generation RMC Room Mode Correction technology is designed to solve the problem. A powerful onboard computer in each LSR4300 Series monitor automatically analyzes the frequency response of your room and compensates for low frequency inaccuracies in the listening space by precisely inserting filters so that low frequency signals arrive at the mix position with the intended frequency response. In effect, the LSR4300 Series goes "beyond accurate," allowing you to eliminate the guess-work and create reliable mixes that translate to any environment. Additionally, the RMC system trims the level of each speaker to compensate for differences in placement relative to the mix position, ensuring balanced mixes.

LSR Linear Spatial Reference Design

Builds on the Linear Spatial Reference technology that has made this Series of studio monitors so popular in recording, broadcast, and postproduction facilities worldwide. The exact geometry of the wave guide, the interaction of the woofer and tweeter, and the ?nal assembly of the injection-molded parts has been redesigned from the ground up to provide accurate off-axis as well as on-axis listening, within a window of +/-30 degrees horizontal, +/- 15 degrees vertical. Attention to these critical aspects results in neutral mid and high frequency response at the mix position and a sound which is smooth and accurate in a wide variety of acoustic spaces.

Surround Smart

Once all monitors are in place, RMC and HiQNet automatically aligns the entire system, setting relative volume so that the sound from all channels is balanced when it arrives at the mix position. The end result is precise imaging regardless of each monitor's actual physical placement.

In addition, the ability to centrally control the volume of all the speakers is particularly useful in surround sound applications where the recording system does not provide a multi-channel monitor volume control, or where adjustable volume is not available when using the mixing system's digital outputs. Similarly, the ability to selectively mute or solo channels and to remotely switch between three digital and analog input sources enhances system capabilities by allowing you to monitor not only the main recording system, but also any two additional connected sources such as DVD and CD players, multi-channel processors and encode-decode units. This alleviates the need to purchase additional outboard monitoring hardware.

Selectable Inputs

In this age of digital workstations and control surfaces, it isn't enough to simply provide an input jack. Offering three separate inputs: stereo high-resolution 96 kHz AES/EBU and S/PDIF digital inputs, as well as dual balanced analog XLR and ¼-inch inputs with selectable +4dBu / -10dBV sensitivity. This allows it to accommodate a wide range of input sources, including digital workstations, CD players, DVD players, and multi-channel processors. What's more, you can easily select between inputs with the push of a single button (on either the front panel or the wireless remote) or click of a mouse (via an attached computer and the included LSR4300 Control Center software).

Onboard Bi-amplification

LSR4300 Series monitors are self-powered, eliminating the need for external amplifiers. Perfectly matched bi-amplification is provided onboard, with 150 watts of power for the woofer and 70 watts for the high frequency transducer.

Features/Specifications:

• Custom designed transducers specially engineered to deliver clean, crisp sound. The LSR4328P model features an 8-inch low frequency woofer, coupled with a 1-inch soft-dome high frequency transducer. All transducers are self-shielded, with Neodymium motor structures for exceptional transient response and superb power handling.

• Advanced front-panel user interface allows control of system functions such as volume, input selection, user EQ and EQ presets, RMC calibration and bypass, individual speaker solo, and brightness level of the meter and buttons.

• Front panel meters show continuous output levels in dBFS to serve as a visual reference of the speaker's contribution when measured at the mix position.

• Integrated mounting points allow wall mounting of speakers when space limitations prohibit the use of speaker stands.

• Built-in side handles make positioning and transporting of speakers easier

• Advanced Linear Spatial Reference design ensures flatter-off-axis response for greater clarity at the mix position

• RMC Room Mode Correction provides electronic control of room modes.

• Integrated bi-amplification with factory calibrated sensitivities.

• Silk dome transducer with Elliptical Oblate Spheroidal waveguide for precise pattern control.

• Magnetically shielded transducers minimize interference when used in close proximity to video monitors.

• Reinforced enclosure and convenient mounting points for mounted installation.

• Integral handles facilitate ease of positioning.
