Sigtronics Spo-63N 6 Place Portable Stereo

The Sigtronics Transcom III SPO-63N is a portable six-place stereo intercom designed with the manufacturer’s High Noise Environment circuitry. It supports communication between connected headset positions while providing auxiliary audio input for a mobile phone or portable music source.

The SPO-63N accepts stereo or monaural aviation headsets and can operate from internal 9 V batteries or 11–34 VDC aircraft power. The six-place arrangement uses a main unit with two remote expansion modules, allowing rear-seat connection points to be positioned separately from the front unit.
