Technologies

• CTA-2006 Compliant: Power ratings on Rockford Fosgate amplifiers conform to CTA-2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
• C.L.E.A.N. Technology: C.L.E.A.N. (Calibrated Level Eliminates Audible Noise) is a patented circuit with in/out clip LEDs to help match a source to amp and optimize output.
• TRANS•ana: Trans•ana is a Class A/B topology that simplifies the signal path of the amplifier allowing the signal to travel through the amplifier at a lower voltage. The result is greater reliability and exceptional sound quality.
• Balanced Differential Inputs: Differential inputs eliminate noise picked up by signal cables.
• Engineered In The USA: These Avatars are a personal signature from the Rockford Fosgate team member(s) who designed and engineered this fanatic product. This statement illustrates our commitment to being Designed and Engineered in the U.S.A.
• DSM: DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
• NOMAD: NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.
• MEHSA³: MEHSA³ reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.
• DTM: Dynamic Thermal Management evenly distributes excess heat across entire amplifier heatsink.
• CE Compliant: This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).
