Bunker Electronics improves sound quality in loudspeaker systems with processor powered by DSP and analog technologies from TI

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 (DSP), PCM4204 analog-to-digital converter (ADC) and PCM4104 digital–to-analog converter (DAC) from Texas Instruments, the BPD-1 is a complete audio solution with advanced signal processing that provides balanced, clean sound.

The BPD-1 brings an unparalleled level of professional audio quality to loud speaker systems by integrating a graphic equalizer, parametric equalizer, compressor, sub-harmonic synthesizer, audio crossover and a real-time analyzer into a single unit. In addition to reducing cost by not having to purchase these as separate components, this 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.

Bunker leveraged a complete system solution from TI, including the C67x DSP, PCM4204 ADC and PCM4104 DAC. The 32-bit floating-point precision of the C67x DSP allows for programming flexibility and ease while its very-long-instruction-word (VLIW) architecture helps maximize the BPD-1’s performance and efficiency. Running at speeds up to 300MHz, 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, respectively, to capture all audio dynamics, without sacrificing headroom. Their high performance helps ensure that any post processing is done only on the audio signal and not on the noise typically found on lower performance competitive multi-channel converters.
