How to use the AUX port
Located near the base of the back side of the BuddyTalk device, the BT110 AUX (Audio output) port takes a 3-conductor TRS jack to play out audio. It does not have a microphone input.
Note that once the TRS jack is plugged into the AUX port, audio will not go out from the speaker but will switch to the AUX port. The microphones will work the same with or without the TRS jack plugged in. Once the TRS jack is unplugged from the AUX port, audio output goes back to the speaker.
