Rockford Fosgate bd500.1, bd1500.1, bd1000.1 manual Introduction, Amplifier Accessory Pack

Introduction

In R&D for 3 years, the engineers at Rockford Fosgate unveiled a new tech- nology for car audio applications, Class bd. The principle was shown to the public at the 1999 CES.The bd class amplifier puts over 1000 watts of rms power in the hands of the serious car audio fanatic-- and does so in the relatively small size of the older Power 250.1 package.

Conventional Class D amplifiers have been around for 60 years in theory and about 30 years in practice. Judging from market acceptance, they are not well suited for full range reproduction.

As known to scholars of this field, a system called Class BD can remove the troublesome, rail-to-rail carrier envelope by differential subtraction in the load. However, since each output is now an untamed full rail-to-rail switching signal, an RFI problem was generated which has eluded solution over the 30 years of Class bd history.

Our new version of this principle, which we call Class bd, solves this fil- tering problem by generating the output pulse waveform without generat- ing the carrier frequency. This unprecedented approach is called Single- Terminal Alternating DUal Sampling Technology - or STARDUST (patent number 6,097,249.)
