The Micro Avionics UL System is specially designed to provide excellent performance in open and closed cockpit aircraft such as trikes, powered-parachutes, gyros and fixed-wing planes. The Micro Avionics UL System is designed and manufactured in England, using the latest electronic technology to produce the most advanced aircraft intercom equipment available. The system is modular in design and can be configured to meet any specific requirement by selecting the appropriate component parts. The Micro Avionics UL System consists of headsets which contain the intercom circuitry and their own rechargeable batteries. Two headsets can be coupled together through a linking adapter for excellent intercom function. Using this system, you can move from one aircraft to another without any fixing equipment. The headsets can be used with or without the helmets. And, the headsets can be used with radio-interface units to allow for radio as well as intercom communication

 .

Radio interface V3 model with LEDs. Not just a simple radio interface. The latest electronic technology were used to produce an efficient powered radio interface with all the features a pilot would require. The user can change various selectable features which reconfigure radio type (i.e. from type ‘A’ [Icom A20] to Type ‘BB’ [Icom A6]) etc, control intercom volume levels, mute audio levels, etc. The voice reproduction through the intercom unit is very bright and clear, optimised for noisy environments. Connection to the mobile telephone is equally as clear and the Audio volume levels can be configured dependant upon what telephone or second radio you are connecting. There is a tone bleeper when you first press the PTT switch to indicate the PTT is activated. Compatible with Lynx Micro System headsets.
Fully specified with five LED status monitors showing power, TX, RX and headset batteries charged. Connect an airband radio, and for chatting to your flying group, a second radio can be connected at the same time. Connection for mobile telephone is a standard feature. Stereo music input (twin audio-in for Hi or Low audio level) and separate stereo audio output. Twin PTT inputs, when P1 transmits the mic on P2 will mute and vice versa. User can select either 10v (Icom A6 etc) or 12 volt (Icom A3 etc) output to power the radio . User adjustable max intercom volume level and adjustable max mic TX level . Music, second radio, mobile telephone will mute automatically once the master radio receives an incoming signal. Auxiliary Control output for two colour LED on the dash board showing RX and TX (optional accessory). The interface comes pre-configured and ready to plug and go. Master radio model has to be specified.
Can be connected to 12V aircraft power supply to charge the handheld radio and headset batteries. The interface incorporates a battery monitor that turns the battery charging circuit off when headsets are fully charged, this extends the life of the headset batteries. No need to connect power as the interface will use the headset power with very low power consumption, typically only 6mA
Included: Ignition Power supply lead MM007, Mobile telephone lead MM011, Stereo Audio input/ output lead MM010.
