Product Overview



  • labCORE provides up to 32 channels at 48 kHz or up to 8 channels at 192 kHz sampling rate
  • The hardware platform can be configured as required for individual test scenarios
  • Based on its modular technology, new technologies can be added to labCORE quickly and easily

Product Features

  • The basic unit of the hardware platform is equipped with common interfaces for measuring audio and communication devices, e.g.:
    • Two analog BNC input and two analog BNC output sockets
    • One USB audio host (type C) port at the front for audio measurements of e.g. USB headsets and headphones
    • One USB type B port for connection of the ACQUA PC
    • Two USB type A ports
    • One headphone output (6.3 mm socket) for measuring and monitoring purposes
    • Two BNC sockets as general purpose input/output (GPIO), that serve as a digital audio interface (e.g. programmable as I2S (Inter-IC Sound))
    • RJ45 Ethernet sockets to connect VoIP applications (e.g. VoIP phones, SIP server, radio tester)
    • Two AES inputs/outputs
    • One ADAT interface (TOSLINK socket)
    • One HEADlink socket (LEMO 8-pin) for connecting HEAD acoustics devices like MSA I or MSA II


  • The functionality of labCORE can be expanded by various hardware and software extensions (e.g. power amplifier, microphone inputs, high-performance and low-noise inputs/outputs, binaural equalization, VoIP extensions, Bluetooth® capability, A2B® extension)


  • The hardware platform is tailored for use with the measurement and analysis software ACQUA


  • At least one of the following software applications is required to control labCORE: ACQUA, RC-labCORE or VoCAS
