Aviation Intercom 4 Ways
This light portable compact is the only intercom you will probably ever need! Designed for Mono and Stereo headsets it allows simple and powerful communications you can count on. You can use any combination of headset with same impedance. The compact design Measuring 11 cm x 8,8 cm x H 3,8 cm and light weight 350 gr. makes it easy to carry in your flight or headset bag. You can take it with you all the time just in case you take an airplane not equipped. For the price and the weight of the four position, no need to have a two position device. No additive module no extra cords or plugs to accommodate additional passengers. Simple is great, don’t you agree…
FEATURES AND BENEFITS
Constructed of strong ABS plastic with round corners, the AVIATION INTERCOM is built to withstand the tough life of a portable intercom. Inside, an electronic circuit board confer high reliability. A logical layout of the front panel make you understand how it works at the first glance. The easily readable prints of the controls reinforce the easiness. From bottom to top the controls are grouped conveniently, a line with female jacks for Pilot and Co-pilot, the line under is for passengers, then a 2 position switch stamped RADIO / INTERCOM allows pilot isolation if on RADIO or to share with others if on INTERCOM position. On the right of the switch a push to talk button. The upper line is with two switches with position indicator on their top, the On / Off Volume switch on the right and the Mute (Squelch) on the left easy to see with its red top. Two little female jack on the left of the switches and vertically placed are marked In and Out. In is to plug any portable MP3, CD or telephone with a jack cord. The out is to allow you to have a recorder plugged in so to record ATC conversation. A nice feature for FI or FE to review the flight with their student.
The battery compartment with a sliding door, accepts a 9 v battery, the space is calculated so the battery cannot move when closed. On the vertical back side a DC 9 v. plug allows you to have an external power. The AVIATION INTERCOM is compatible with either our solar charger or 12 or 28 volt electrical systems and connects with a power-cord. If the power supply to the intercom is lost, the intercom automatically switches to battery back-up power.
THE FUNCTIONNING DETAILS
When you turn on the intercom the Push to Talk button is lighted in red if no headset jacks are plugged in. When the headsets jacks are plugged in when the voice-activated (VOX) is working the red light turns off, when everybody is on stand by and the voice activation (VOX) is not active (SQUELCH minimum) or very low. When you speak or when the squelch is not properly set the red light turns on again.
The voice-activated squelch circuit (VOX) adjusts to noise environment or can be set for a continuous open-mike condition (red light continuously on).
An integrated circuit allows you to use mono or stereo headsets. The convenient push-to-talk button for the pilot on the front panel gives a pilot-priority feature. This function permit to the pilot to over-talk the co-pilot transmissions. Pilot isolate (RADIO) provides exclusive pilot communications with the ATC. Other communications between headsets are not possible The “fail-safe” feature gives a direct connection to the aircraft radio in case the power supply to the intercom is disrupted. The AVIATION INTERCOM is equipped with a music-in jack for in-flight entertainment with automatic muting during intercom or radio activity (cable not included). This female plug (IN but also the OUT) can also be used to plug in a telephone (cable not included). This feature is not an in-flight feature that could be dangerous but could be use before starting engine for example (for your flight plan registering). Add an audio recorder and with the record out (OUT) feature, you can record ATC transmissions or cockpit conversations.
