The TM500X1br is a 500 Watt mono amplifier with boosted rail Class-br technology and a conformal coated pc board designed for motorsport and marine applications. Class BR Stores energy and dynamically boosts rail voltage to create power on demand. CEA-2006 Compliant Power ratings on Rockford Fosgate amplifiers conform to CEA-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. 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. CE Compliant This product fulfills all essential safety and environmental requirements as defined in the European Directives (768/2008 EC). Constant Power Constant Power is a patented circuit topology that provides instantaneous delivery of output power over varying impedance loads. Element Ready™ - Amps These amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware. The Power TM500X1br 500 Watt mono ultra-compact amplifier is built on Rockford Fosgate’s patented Boosted Rail technology that sips current while retaining a storage reserve for extended bursts of power. Flexible vehicle integration enabled through low-level and high-level inputs with auto turn-on. Top mounted controls allow easy access to built-in crossover and C.L.E.A.N. input/output clip detection circuits. The 3-stage thermal lock extrusion with dual fan forced induction keeps everything cool while real-time thermal/protection schemes safeguard the amplifier. 3-Stage Airflow 3-stage airflow method effectively exhausts heat and ensures your amplifier runs cooler for optimum performance. DSM DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.
