More advanced than the TruTrace EMG 4ch EP Headbox, this unit offers more flexible, hardware-interchangeable settings. While it can also serve as a TruTrace EMG 8ch Headbox, it is specifically designed to simplify EP examinations using an internal hardware switch, eliminating the need for cable changes during the examination. It includes two 5-pin DIN connectors (with pins for patient ground and shielding), individual active, reference, and patient ground connectors with 1.5 mm touch-proof connectors, and a temperature probe connector.
