RX6 MultiFunction Processor

The RX6 Multifunction Processor has been designed with high quality, wideband audio signals in mind. Superior analog input/output and a novel multi-DSP architecture combine to provide exceptional processing power, fast data transfer rates, and a realizable bandwidth of 120 kHz. This processor is supported by a complete line of audio signal processing accessories, and can be used with our electrostatic speakers to generate ultrasonic acoustic stimuli for animal studies. Used with our headtracker interface, the RX6 becomes a powerful 3-D platform for complex real-time audio presentation, HRTF filtering, multiple virtual sound and many tap FIRs.
