Literature

The PM500X1bd is a 500 Watt mono amplifier with high dynamic power using Class-bd technology and a conformal coated pc board designed for motorsport and marine applications.

Overview

With its super efficient Class-bd circuit topology, the PM500X1bd will drop some serious BASS! Due to its dedicated low frequency response, this amplifier is optimized for mid-bass speakers or subwoofers only. No need to worry because its 1-ohm capability will drive a pair of 4-ohm DVC subwoofers or quad-configuration of 2-ohm DVC subwoofers with ease.

Technologies

CE Compliant

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

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.

Element Ready™ - Amps

These amplifiers are protected against Dust, UV, Corrosion, and feature Stainless hardware.

Class BD

Class BD amplifiers have 75-80% efficiency ratings vs. 20-60% efficiency ratings of traditional class A/B amplifiers.

Balanced Differential Inputs

Differential inputs eliminate noise picked up by signal cables.

DSM

DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature.

MEHSA3

MEHSA3 reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span.

NOMAD

NOMAD is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances.

 

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.
