    Broadcasting, recording, speaker JBL LSR4328P

    JBL unique second generation RMCTM Room Mode Correction technology specifically designed to solve this problem . In each LSR4300 Series monitors are equipped with powerful computing processors can automatically analyze the frequency response of your room , and through precise low frequency error filter insert compensation listening space, so that the low-frequency signal reaches the mix position having a desired frequency response . Because of this , LSR4300 series can be "beyond accurate " to help you to eliminate the guess work of uncertainty can mix to create reliable in any environment exchange. In addition , RMC system can fine-tune the level of each speaker to compensate for the speaker to the mix position relative distance differences to ensure a balanced mix.



    Features:

    • Custom designed sensors especially for transporting clean, crisp sound. LSR4328P has an 8-inch low-frequency cone , LSR4326P provide 6.25 inches bass, two models are equipped with one inch speaker soft dome high frequency transducer . All sensors are self- shielded, neodymium motor structure can be adapted to the transient response and the occasional power used.

    • Advanced user interface front panel control system functions , such as volume , input selection, user EQ and EQ presets , RMC calibration and bypass , solo single speaker , headers and buttons to adjust the brightness .

    • When measured at the mix position , the front panel header displays a continuous output level , in units of dBFS, could be used as a visual reference to the speaker output .

    • When space is limited , you can not use the speaker stand , the speaker 's own body mounting points can be wall-mounted speakers .

    • Speaker concave side with handrails for easy speaker positioning and handling.
