DBX4 – 4 Ch Full Range Digital Amplifier (Built-In OEM Line Converter)

The DBX4 is currently the most powerful CEA Certified full range digital four channel amplifier on the market. It is remarkably compact for a 2000W amplifier with dimensions that make installation in any location possible. Its digital design allows for high efficiency via its low power consumption while providing clear signal with low distortion.

To truly appreciate this amplifier all one has to do is examine its many high tech features. The Low Pass crossover is adjustable from 50Hz – 6 KHz with the use of the X11 switch. The High Pass crossover is adjustable from 20Hz – 45 KHz or 360Hz – 6 KHz. This permits HP/LP/Band pass configurations that allow the use of raw drives without passive power robbing crossovers. The DBX4 has a single band parametric equalizer (-6Db~+ 12Db @ 30Hz – 120Hz). Built in OEM integration, via the supplied RCA “bullet” adaptors, allow the installer to wire directly into the RCA inputs which in turn activates the ‘Auto Turn-On’ feature.

Look close and you’ll see a “docking port” on the end cap. This allows the optional DBX4 Farad Rail Capacitor to connect directly to the power supply for improved dynamics and power balance. Massive Audio has raised the bar once again with the Digital Quad Powered DBX4!
