CE Compliant

This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC).

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.

C.L.E.A.N. Set-Up

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.

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.

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.

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.
