RX6

RX6 MultiFunction Processor

 

 

Multifunction Processor (RX6)
Filter and play out high quality auditory signals in real-time.

 

 

ED1
The broadband electrostatic speaker driver has an incredibly flat frequency response far into the ultrasonic range and can drive two ES or EC series speakers.

 

 

 

ES1
These lightweight speakers deliver ultrasonic stimuli with very low distortion.

 

 

 

HTI3
Acquire 3-D spatial information using a Polhemus FASTRAK® or Ascension Flock of Birds® motion tracker.

 

 
   

 

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.
