RX8

RX8 Multi I/O Processor

The Multi I/O Processor (RX8) is a high channel count analog input/output system. Available with either 12 or 24 analog channels, the RX8 can be configured to your specifications at the factory. Combine PCM or Sigma-Delta A/Ds and D/As to create a system matched to your application. The Sigma-Delta converters have a dynamic range of over 100 dB with a maximum bandwidth of 50 kHz, making them ideal for audio applications. The PCM converters, with almost no group delay, are excellent for controlling external devices such as microstimulators or motors in real-time. Combine the RX8 with the RX5 for a complete physiology workstation or consider the RX6 for auditory applications that require higher sampling rates. A complete line of transducers and amplifiers are available to round out the system.
