CONNECTORS ON THE FRONT Headphone Output You can connect one of our compatible headphones to the headphone output and use it to play back correctly equalized recordings. The two pulse inputs Pulse In 1 and Pulse In 2 are available for direct CSB VII.0 connection of pulse sources. The pulse signals are sampled at 32 times the system sampling rate. At a system sampling rate of 48 kHz, pulse frequencies of up to 600 kHz are available; at 96 kHz, pulse frequencies of up to 1 MHz are available. The following equalizations are available: Independent of Direction (ID), Free Field (FF), Diffuse Field...

CONNECTORS ON THE BACK HEADlink labCTRL II.1 Using this connector enables you to connect SQuadriga III to a HEADlab controller and integrate it into a HEADlab system. SQuadriga III then operates like a HEADlab module. You can also connect an additional SQuadriga III which will then function as a controller, configuring and recording the sensors connected to both SQuadriga III devices. HEADlab module This connector enables you to connect a HEADlab module (the SQ3 TP 05 option package is required) and supply it with power via SQuadriga III. You can also connect an HMS V artificial head or another...

IN PRACTICE Intuitive Operation The complete range of SQuadriga III functions can be operated via the 7-inch touchscreen (1024 x 600 pixels). Common gestures, such as those used routinely on a smartphone, can also be used here: tapping activates buttons and initiates functions, whereas swipe gestures enable you to scroll through lists, for example, the list of stored files or settings. Using two fingers, you can zoom in on analysis diagrams or adjust the video image. During a measurement, the display shows all relevant information in real time, including the levels of the active channels and...
