JBL SDEC-4500X Overview

The SDEC-4500X uses the company's renowned Harman Audio Test System to achieve flat in-room frequency response, or to correction to any desired target curve. Using up to eight microphones, the system measures different locations in a room and applies proprietary digital-signal processing to analyze and correct for dips and peaks that may be present.

Whether used with a JBL Synthesis complete multichannel audio system or in a custom installation, the SDEC-4500X is a vital component that brings the ambiance and acoustics of some of the world's finest concert halls and theaters into homes.

JBL SDEC-4500X Features

The Synthesis(r) SDEC-4500X is a digital equalizer designed to optimize the performance of JBL Synthesis systems in any room. It uses more than 500 bands of fully parametric digital equalization to correct dips and peaks that are inherent in a room’s frequency range, resulting in a flatter, more accurate in-room frequency response.

It applies this equalization to all main, center, and surround speakers in a home theater system, and to multiple subwoofers. It also offers an improved Auto-Film-Screen-Compensation feature that automatically corrects for the attenuation in high-frequency output that can occur when a loudspeaker is located behind projection screens of various materials. It has many other versatile features that include automatic arrival-time calibration for all loudspeakers and drivers in a multichannel system; the ability to control the SDEC-4500X with other JBL Synthesis components; a new "control panel" interface; and more.

  4. After Sales Support - The only issue with Hi-Fi equipment is that you will not find local service centers in every city. Most of the brands have their service centers only in the metro cities and hence it becomes difficult for the customers who are living far away places to claim warranty. At AV Kart, we solve this problem by arranging pikcup and drop facility from the nearest service center with the help of our logistic partners.
