Amplifier/converter

Amplifier / Converter Modules are miniature PC boards that are installed in the A/D Interface Box to add channels to the ActiveTwo system.  Each Amplifier / Converter board adds eight monopolar channels to the system, and each A/D Interface Box can accommodate up to eight Amplifier / Converter Modules (256 channels).  These channels can be configured for use with:

• Active electrodes, available in pin-type or flat-type.
• Optional Sensors for galvanic skin response, respiration, temperature or pulse.
• Passive electrodes wired to the standard 68-pin input connector.  Active electrodes provide far superior performance compared to passive electrodes, so we offer this option only for special circumstances where the active electrodes are not appropriate.
• Auxiliary analog inputs wired to multi-pin circular DIN connectors on the front panel of the A/D Interface Box.  These analog inputs are available only for use with battery-powered and self-powered signal sources such as a condenser microphone or photocell.
• Input Buffer Box for adapting channels configured for active electrodes for use with passive electrodes.

All channels on an eight channel Amplifier / Converter Module must be configured identically.
