Outstanding Helmet/Intercom System .Superior Noise-Attenuation .Quality Performance  

Whether used for instruction or pleasure, the ULTRA PRO Standard Model INSTRUCT -A-COM system with Dual Com II will provide quiet protection from engine and wind noise.   

This package comes fully assembled and consists of two ULTRA-PRO Standard audio-equipped helmets, one DUAL-COM II intercom with a push-to-talk switch and power cord which can be connected to a 12-volt power source. An optional music cord is available to connect to a tape player or FM receiver.  

The original ULTRA-PRO Standard helmet is a comfortable, superior noise attenuating helmet. The other component of this package is the DUAL-COM II intercom which features our proprietary two-channel circuitry. This unit provides distortion- free voice transmission and can be used as an intercom only. When used with the appropriate interface cables, it may be connected to two transceivers for air-to-air or air-to-ground communication.  

Features also include superior frequency response, excellent sound quality and impedance matching circuitry to interface with most hand-held transceivers.

The Comtronics DUAL-COM II intercom is the only intercom made exclusively for ultralight and light plane operation that will selectively receive and transmit on two transceivers without modifications.

In addition to the same circuit as that used in our popular ultralight intercom, we have added a very efficient switching circuit that makes the unit even more versatile. It provides a pilot the option to transmit from either of two separate transceivers while monitoring both simultaneously.

For instance the pilot may wish to contact his ground crew via one transceiver and also notify a nearby airport of his location and intentions on another All of this can be accomplished by using the simple switching circuit provided.

The entire circuit has been placed within a metal enclosure of overlapping construction to effectively shield out RF and EMI interference. The selection process is controlled by one toggle switch located on the front surface of the box. Radio actuation is controlled by a single push to talk switch which may be mounted on the aircraft in a convenient location, such as the pilots control stick.

In addition to the dual transceiver interface, the intercom includes a 9-volt battery for back-up and a 12- volt power jack with a voltage regulator built in. On the back side, there is a music input por1 that may be used for an FM radio or tape player.
