The audio interface system that resides within the FC-1 comprises of two 300mw power amplifiers designed specifically for aviation headphones. Aviation headphones in general do not generally offer the bandwidth that one would typically find in a high quality stereo headphone system. The FC-1 uses an equalization system specifically designed to compensate for loses found in aviation headphones. Overall gain is about 9db with input buffers to balance ship radios gain to the Aux I/O. The net results of this is a far better sound quality from any music that is played through the system, a much improved signal to noise ratio and a crisper, cleaner voice reproduction from the planes radio system.
By plugging the unit directly into the existing headphone jacks ( phones and mic) the unit performs a seamless interface connection that allows the pilots headphones to continue to use the ships audio while at the same time provides the Aux I/O to be used with an MP3, Iphone, or Blackberry. Cell Phone audio is of course conditioned and routed through the system providing noise reduction and safety. The FC-1 has a self contained VOX (Voice Operated Xchange). This feature mutes any audio coming from the Aux input any time there is audio activity on the intercom or radio. That means that even intercom chat from one passenger to another will mute the systems Aux Audio which includes the MP3, GPS audio, and cell phone. This feature guarantees the intercom and ATC always take presidents.
When it comes to audio, one key requirement is POWER. This is an audio interface that incorporates two large power amplifiers to compensate for some limitations inherent to aviation headphones. Couple that with an ability to import MP3 and cell phones offers the pilot a smooth and seamless transition to high quality sound for both radio/intercom and music.
The cell phone interface is designed specifically to reduce the noise that is so prevalent on most cell phone adaptors. This is accomplished by using of the aircrafts own intercom as part of the cell phone operation. This unique design vastly improves cell phone operation.
A VOX (Voice Operated Xchange) system within the unit mutes cell phone reception and MP3 audio any time there is any audio activity present on the intercom keeping the marriage between pilot and ATC happy. Operates on a single 9 Volt battery. |
