Audio Processor For Loudspeakers Uses TI DSP

The BPD-1 audio processor integrates a four-way stereo system and six audio control components in a one-rack unit space. This allows consumers to experience exceptional audio quality from loud speaker systems in a compact and flexible design. Featuring a floating-point TMS320C67x digital signal processor, a PCM4204 analog-to-digital converter, and a PCM4104 digital–to-analog converter from Texas Instruments, the BPD-1 is a complete audio solution with advanced signal processing that provides balanced, clean sound. The processor integrates a graphic equalizer, parametric equalizer, compressor, sub-harmonic synthesizer, audio crossover, and a real-time analyzer into one unit. This reduces costs and allows consumers to select the optimum frequency ranges for their loud speaker systems and enhance the bass sound to user preference without worries of any audible deficiencies, alignment delays, or saturation. Running at speeds up to 300 MHz, the DSP can handle several channels of audio so the BPD-1 can meet the processing requirements for enhanced sound quality of professional applications. The PCM4204 and PCM4104 audio converters offer four channels of 118-dB conversion to capture all audio dynamics, without sacrificing headroom. The BPD-1 costs $500.
