General description

The Quattrocento is a 400 channel desktop bioelectrical amplifier. It can detect surface electromyographic, intramuscular electromyographic and electroencephalographic signals at the same time. The signals acquired by the instrument are amplified, filtered, digitally converted and then transferred to a PC, via an USB2/Ethernet interface. OTBioLab+, a freeware software designed by OT Bioelettronica, allows to display the signals online, to acquire and process them. Moreover, the data collected by OTBioLab+ is available on a TCP socket and can be accessed online by different software or different computers running any kind of operative systems.


In addition to the information obtainable with bipolar system (timing and degree of muscle activation), with Sessantaquattro users may:

  • identify anatomical muscle features;
  • decode the neural drive to muscles;
  • quantify the spatial distribution of muscle activity.


It is possible to visualize different types of signals: surface electromyography (sEMG), intramuscular electromyography (iEMG) and electroencephalography (EEG):

  • Available versions: - 96 channels - 192 channels - 288 channels - 384 channels
  • 16 auxiliary input channels
  • 1 analogue output
  • 1 input / output trigger
  • Ethernet connection
