Using the Bose® Aviation Headset
Installed connector
An optional installed connector is available for pilots who want to hardwire the DC power, incoming audio, and outgoing microphone functions permanently into their plane. The panel mount receptacle comes wired with a 6 foot harness to simplify the installation process. To order this connector, contact the Bose Aviation Headset Service Department (page 23).

Installing the wire harness
Note: This installation must be done by mechanics qualified to perform this type of avionics installation for the aircraft in which the installed connector will be used.
A .5 in. x .56 in. (1.27 cm x 1.42 cm) cutout is required to mount the connector as shown in Figure 9. There are 6 wires to connect: 2 for microphone, 2 for audio, 1 for power, and 1 for ground. The audio and microphone wires should be con- nected to the back of the existing microphone and phone jacks. This leaves the existing jacks intact for use with conventional headsets and is usually the fastest installation method.
The pinout for the optional installed connector is as follows:
Pin | Wire | Description |
1 | Red | Headset power |
|
| breaker. |
2 | Black | System ground. Connect to the existing audio ground. |
3 | White | Phone |
4 | Black | Phone |
5 | White | |
|
| that corresponds to the ring position of a headset micro- |
|
| phone plug. Do not connect to the tip (PTT) segment. |
6 | White/Blue | |
|
| jack that corresponds to the barrel position of a headset |
|
| microphone plug. |

Notes:
1.If used with a stereo intercom, connect the left and right channels to their respective positions. For mono operation, connect Pins 3 & 4 together to the tip portion of the existing phone jack.
2.Do not bend or use excessive force on the installed connector. Doing so may damage or break the internal solder joints.
3.If the boom mic works on radio transmit but not through the intercom, check Pin 6. It is probably miswired to the PTT segment of the mic jack.
4.The wire connecting Pins 3 & 4 and 5 & 6 are shielded, twisted pair with a shield termination exiting with a black wire for each pair. Connect shields to existing audio wiring shields, or audio ground if the existing wiring is not shielded.
