The device uses two cables which are plugged in at the top of the device. The earphone cable has
colored transducers which contain speakers to generate the clicks, microphones to listen for
ambient noise, and a memory chip which stores cable calibration information. The preamp or
sensor cable contains colored clips which attach to the Natus sensors, and a preamplifier to
transmit responses back to the ALGO 3i screener. The earphone and sensor cables are each
available in two different lengths, 31 inches (78.7 cm) and 90 inches (228.6 cm). The short cables
are the ATA 3i (earphone) cable and the Preamp 3i (sensor) cable. The long cables are the ATA
3 (earphone) cable and the Preamp 3/PCA 3 (sensor) cable.
