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 radios. Also features a sidetone modification. Made in USA.
