We frequently receive questions from pilots regarding Bluetooth functionality when using the Harmony System. To clear up confusion and help you optimize your cockpit communication, here's a straightforward breakdown of what you need to know.
Why Bluetooth Disconnects Automatically
First things first: when you connect your Harmony System—or any wired connection—to the headphone jack of your wireless headphones, the Bluetooth feature is automatically disabled. This isn't an oversight or limitation of the Harmony System or your headphones. Rather, it's an intentional safety feature implemented by headphone manufacturers. It prevents headphones from simultaneously receiving multiple audio streams, protecting you from sudden and potentially harmful volume spikes or audio confusion.
Adding Bluetooth Capability via Dongles
While Bluetooth from your headphones is deactivated when plugged in, you can easily introduce Bluetooth functionality using a simple, third-party Bluetooth dongle. To do this:
- Plug a Bluetooth dongle into the 3.5mm jack located at the bottom of your Harmony System.
- Connect the dongle wirelessly to your smartphone, tablet, or other Bluetooth-enabled device.
Audio transmitted through this setup will play at the same volume as your aircraft communications or ATC transmissions. Be cautious: carefully adjust your device's volume beforehand to maintain comfortable and safe audio levels.
Receiving vs. Transmitting Bluetooth Audio
It's important to note that not all Bluetooth dongles are created equal.
- Receiving-Only Dongles: Many affordable Bluetooth dongles, like this one from UGREEN, only support receiving audio. While great for listening to music or audio notifications, these dongles will not transmit your microphone output. This means ATC or other communication devices won't receive your voice through the dongle.
- Two-Way Bluetooth Dongles: If you require both receiving and transmitting capabilities, you'll need a two-way Bluetooth dongle, such as this one available on Amazon. These dongles transmit your microphone audio wirelessly to connected devices, perfect for scenarios requiring hands-free phone calls or communicating via mobile apps. When using these two-way dongles, make sure to set the "Line-Mic" option to "external" to ensure correct operation.
Final Thoughts
Understanding your Bluetooth setup ensures safer, clearer cockpit communications. The Harmony System provides flexibility and clarity for your aviation audio needs, especially when correctly paired with the right Bluetooth dongle.
