iM Module

TDT’s iM Multi-Function module is designed for basic and complex signal generation and acquisition. The system generates tones, noises, and complex wave forms. The iM easily acquires signals from microphones, accelerometers, and other devices for advanced audio processing.

To make the system truly multi-functional, TDT added components to control your third-party behavioral devices. These include feeders, cue lights, LEDs, mechano stimulators, or nose pokes.  

Choose from different iM models which include:

  • 1-2 analog inputs and outputs 
  • 1-2 digital inputs and outputs
  • 1 or more touch sensors for devices that need a closed circuit, such as lickometers or aversive stimulators


Research Uses


  • Behavioral
  • Auditory

Standard feature of all iCon modules

  • Precise timing control of all inputs and outputs, with fixed or continuous duration signals
  • Perfect synchronization with external behavioral events such as cue lights, lever presses, and more 
  • User friendly names for all device controls 
  • Run time control of all variables such as frequency, intensity, and duration
  • Seamless integration with Pynapse for your behavioral experiments 


Features of the iM Module

Auditory Features

  • Tones from 1 Hz to 100 kHz 
  • White and pink noise from 1 Hz to 100kHz 
  • FM and AM modulation of the waveforms 
  • Ability to mix signals from two channels into one  


Control of External Devices

  • DC output to control external devices 
  • Pulse code modulation to drive LEDs and other interval based signals 
  • Clock out to synchronize multiple external devices
