Barrington, IL (May 29, 2009)--Bag End Loudspeaker Systems has upgraded its Minima One amplifier module to make it RoHS (Restriction of Hazardous Substances Directive)-compliant, 80-84 percent power efficient, reportedly creating less heat while drawing less electrical power, and yet delivering the same output result.
The smaller size and weight of the Minima One lowers the shipping cost of speakers and the amount of packaging material needed. It also enables speaker cabinets housing the Minima One to be reduced in size, often a big advantage for installed speakers. Lower energy demand lowers the impact of producing that energy.
"Given the growing emphasis on 'green' technologies and conserving the environment these days," points out Bag End president Jim Wischmeyer, "these multiple reductions in environmental impact give the Minima One and the speakers it powers an additional competitive advantage."
Incorporating patented technology, the comparison circuit of the Minima One module corrects each individual cycle. On average, every 4 microseconds, the one-cycle modulator transforms and amplifies the input signal into the natural pulse width modulation. According to the company, switching at 250 kHz with the single cycle error correction insures low distortion and high reliability.
