The Sigtronics Transcom II SPO-22N is a portable two-place aviation intercom designed for high-noise operating environments. The “N” Series incorporates high-noise circuitry intended to support clear cockpit communication in demanding environments such as open-cockpit aircraft, ultralights and helicopters.

Voice-activated communication enables hands-free conversation between pilot and passenger. The unit provides radio priority during transmission and a fail-safe radio communication function, allowing the pilot to hear and transmit through the aircraft radio even when the intercom is switched off or its battery is depleted.

  • Manufacturer part number: SPO-22N
  • Two headset positions
  • Portable, battery-powered design with supplied auxiliary DC power cable
  • Operates from one 9 V battery or 11–34 V DC aircraft power
  • Approximate battery operating time: up to 40 hours
  • Auxiliary audio input for a compatible external audio source
  • Audio output for recording flight communications
  • Inputs for pilot and copilot push-to-talk switches

Overview

Discover the dramatic improvement in flight cabin conversation with Sigtronics' Transcom II. Pilot-to-Passenger hands-free conversation, radio transmit capability, battery power or auxiliary power, and input-output source all rolled up into one! All standard aircraft headsets and portables push-to-talk switches are compatible with the Transcom II. A music input makes long trips more enjoyable for crew and passengers, and an audio output records flight dialog for post-flight review, a great training tool for any pilot. Coupled with a standard 5-year manufacturer's warranty, this is a sure-fit for all students, instructors, and aircraft renters.

Powered by an internal 9V battery (included), the SPO-22 is good for 40 hours of operation in airplanes lacking a cigarette lighter socket. A 4-foot Aux power adapter is included to allow for seamless operation on either battery or 11-34 Volt DC aircraft power. When using the power cord, the battery is by-passed, preserving the life of the battery.

High Noise Version
The Transcom II is available in a High Noise Environment version. The SPO N Series intercom incorporates special high-noise circuitry that works well in ultra-lights, helicopters, open cockpit aircraft, and with handheld radios. It filters out background noise, lowers the input level at mic amp, increases output signal, and mic interface can be modified to interface with Icom radios. Also features a sidetone modification.

Made in USA.
