Biforst Technology Inc. is a professional fabless IC design company founded in 2002. Gathering a team of experienced and talented expertise in R&D, sales, marketing and management, Biforst is to develop and manufacture products applying digital signal processing (DSP) technology. Although Biforst is a young company, Biforst has developed his unique amplification technology called LDA®, Biforst’s Lossless Digital Amplification Technology, which makes Biforst in the leading position of the market. LDA® is designed to provide the interfaces of digital audio data input formats such as I2S, S/PDIF…etc. That means the digital signal from CD, DVD, MP3 players or digital radio can directly enter into the chip and be amplified to speakers. LDA® improves obviously in both distortions and power efficiency. Biforst’s products not only reproduce the pure digital sound from the source but also enhance woofer by extraordinary separation of high and midrange frequencies with low frequencies. Besides, Biforst’s products are packaged in very compact size because the high power efficiency eliminates the extra device for heat dissipation. Low power like 5V applications of LDA® is the best solution for USB Speakers of 2 or 2.1 channel, portable DVD, portable Audio devices and DAB (Digital Audio Broadcast) receiving devices. LDA® also provides applications in middle range power, ranging from 8 to 12 volts including DVD Home-Theater_in_Box of 5.1 channel, LCD TV of 2 or 2.1 channel and Car_Use audio systems.
