JBL LSR4328P Studio Monitor Pair

Automatically analyzes and corrects the sound for accurate mixing.




The JBL LSR4300 Series Studio Monitors are
designed for critical stereo and multi-channel audio production
applications that require exceptional spectral accuracy and high SPL
capability. Exclusive technology from JBL automatically analyzes and
corrects the response of each speaker in the room for absolute accuracy
in mixing.

Acknowledging that much of today's production is
carried out in acoustically untreated rooms, the LSR4300 Series is the
first professional monitor to combine JBL's Linear Spatial Reference
technology and automated RMCTM Room Mode Correction, an onboard system
that automatically compensates for low frequency anomalies measured at
the mix position.

The LSR4300 enhances computer-based production
by incorporating system-wide volume control, input source selection,
individual speaker solo and user EQ. Harman HiQnetTM Network protocol
enables centralized system-wide control from any speaker, wireless
remote control, or computer using LSR4300 Control Center Software.

438H Low Frequency Transducer

The
8" woofer utilizes a powerful, shielded lightweight neodymium magnet
which can be used in close proximity to CRT-type monitors with no
interference. The transducer utilizes a copper-clad polepiece that
improves high frequency output by reducing voice coil inductance. A
copper ribbon voice coil ensures high sensitivity, and a flux shorting
ring stabilizes the magnetic field in the gap, reducing distortion. Heat
sinking has been placed close to the magnetic gap in order to draw out
heat as efficiently as possible. The cone is polymer coated for
uniformity of response over the woofer's passband.

431G High Frequency Transducer

The
high frequency transducer has a treated silk diaphragm that produces
uniform and smooth sound. Its flat ribbon aluminum voice coil ensures
low-moving mass and enables the transducer to achieve response out to
22kHz. A lightweight neodymium magnet structure with integral heat
sinking, along with ferrofluid in the magnetic gap, enable the
transducer to produce high peak output levels with minimal power
compression. The magnet structure is integrally shielded, enabling the
system to be used in proximity to CRT-type monitors with no
interference.

Bi-amplified Power System

The LSR4328P
incorporates 2 high power amplifiers that provide 150 watts of power to
the low frequency transducer and 70 watts of power to the high frequency
transducer. A precision digital dividing network having high-order
Linkwitz-Riley slope characteristics for smooth transition between
transducers, results in exceptional imaging and lack of time smear. The
circuitry also yields a tonal-artifact-free noise floor.

Network and Digital Features

The
LSR4300 Series utilizes the Harman HiQnetTM network protocol that
allows centralized control of a multi-channel system from a from any
speaker's front panel, wireless remote control, or computer via a
standard USB connection and LSR4300 Control Center Software. The network
is configured using supplied CAT5 cable and by setting a DIP switch on
each speaker. Harman HiQnet also enables synchronized RMC calibration of
all speakers on the network.
