Massive Audio, a California USA based leader of 12 Volt Audio for over 15 years, is pleased to announce the shipping of their New 2014 Digital Bit Series 1000W DBX4 four channel full range digital amplifier. Designed and built in Massive Audio’s new factory. Please do not let the tiny 1.9”H x 5.9”W x 9.4”L footprint fool you. The DBX4 is a power house that has clean and efficient digital power with features found on amps costing twice as much. Massive Audios Innovative Design features include a dedicated docking port for the (optional) Massive Audio “Rail Cap X.” The Rail Cap X is a dedicated 4 farad capacitor that wires directly to the MOSFET power supply for improved voltage control. The Massive Audio DBX4 is CEA-2006 compliant.
