MGL Avionics A14 and A16 modular Aircraft intercom system
The A14 and A16 provides a compact solution for an advanced intercom system specifically designed for aircraft use.
Support for 4 or 6 independent headsets, single or dual circuit stereo with a rich selection of wired audio source inputs including a stereo music source. Music streaming from Bluetooth enabled sources is also provided as well as hand-free profile for mobile phone use. Simultaneous support for two Bluetooth audio devices is possible.
Support for two COM radios with PTT multiplexor. Fully digital integration with up to two V16 COM transceivers - no analog audio or PTT wiring required.
Includes a cockpit voice recorder (CVR). Records last 35 minutes of combined active audio from 6 headset microphones and the two COM radios.
The A16 is intended to be controlled either via an EFIS system (iEFIS G3 or MX1) and/or via a Razor 3.18” touch screen control head. It is possible to connect multiple heads and have simultaneous control via EFIS and head(s).
Firmware updates on both A16 and Razor can be performed either via wired RS232 port or via Bluetooth wirelessly.
Communications protocols are available for third party use.

Optional Razor control head
The Razor control can be used to control all aspects of the A14/A16 including all configuration, setup and signal monitoring.
The Razor connects to the A14/A16 via a two wire CAN bus. More than one Razor may be fitted to this bus to make it possible to control the A14/A16 from more than one position.
Modular audio intercom systems can significantly ease aircraft wiring systems as is becomes possible to optimize audio wiring routes behind the panel. There is no longer a restriction that all audio wiring must be concentrated at the location of a panel mount intercom system.
The A14 and A16 provides noise canceling inputs and ships with very effective RF block devices to prevent common issues such as RF feedback during transmission caused by ground loops or other issues.
RF and DC block device (The A14/A16 kit contains two, available separately as well).
This small device is a highly effective component that can be installed into Audio wiring inline. Two installation methods may be used - DC isolated which breaks troublesome ground loops as well as DC conduction which can be used with headset microphone feeds.
This device eliminates RF feedback problems in compromised installations with high powered transmitters which can cause effects such as howling, squealing or distortion during transmit.
Please view the A14/A16 manual on information on how to use this device.
