![]() ![]() Once the type of headset has been identified, the next step is to identify the parts of the wiring diagram. It is important to make sure that the correct type of headset is being used before proceeding with the wiring diagram. Wired headsets require the use of a special plug, while wireless headsets usually connect via Bluetooth. These include both wired and wireless headsets. When looking at an aircraft headset wiring diagram, the first step is to identify the type of headset being used. The diagrams also include instructions on how to connect the components and which components are used. This includes the pins, plugs, contacts, and other components necessary for connecting the headset. For the most part, the diagrams will consist of a schematic representation of the wiring system. The wiring diagrams take on a few different forms, depending on the type of aircraft and headset being used. In order to successfully connect the headset, it is important to understand the wiring diagrams. The wiring diagrams allow pilots to connect the headset properly, allowing for easy communication between the pilot and the aircraft. Aircraft headsets are essential for pilots, as they provide vital communication between the pilot and the aircraft’s control systems. Here is a comprehensive guide to aircraft headset wiring diagrams. A headset wiring diagram is a tool that can make the process easier and help ensure that all connections are done accurately. Understanding the ins and outs of connecting headsets correctly is essential for any pilot. Otherwise there is a potential for a difference in grounds from the Headset shields and the GND of the LEMO (and GMA), which would result in noise in the headset speakers.Aircraft Headset Wiring Diagram: A Comprehensive Guide For pilots, a crucial part of their experience is the use of aircraft headset wiring diagrams. We’d like to support our drawing if any issues exist, but acknowledge each aircraft may be wired different.įor purposes of keeping grounds at the same point, we recommend running all shields and the LEMO 2 GND back to the GMA or source unit. Other variations may also work also as each aircraft is different. The Garmin drawing is recommended for best overall performance. For audio carrying wiring, the shield of the wire should be terminated at the audio panel end only.įor cases where a LEMO is being connected to an existing jack, maintaining a shield connection from jack wiring to LEMO wiring (and then back to the audio panel) is important when the distance between jacks is longer than a foot.įor cases where a LEMO is the only jack (diagram shown in Garmin audio panel IM’s), the connections should be run to the audio panel as shown in those diagrams for best performance in regards to reduction of noise. For the shields we recommend wiring as shown. For the power return (the LEMO 2 GND), we recommend that go back to the audio panel as shown to prevent power return noise from the HS low. The best performance for a low noise solution is to always wire back to the audio panel (or source). The power for the headset returns in the LEMO 2 GND, which is also tied to the headset shields. In the LEMO connector the MIC has its own Lo, but the HS and Power share a return path. Garmin’s LEMO connector drawing is recommended as the best case for wiring to the GMA audio panels. ![]()
