Bluetooth supports HFP (including HFP v1.6 WideBand Speech mode), A2DP, and AVRCP.The GMA stores 10 paired devices and overwrites the least recently connecteddevice when a new device is paired. Only 1 Bluetooth connection allowed at onetime. The VIRB XE cannot be connected when using a phone (and vice versa).USB Charge PortUSB charge port - Rated for 10 W. The GMA 245 charge port features USB portdetection that will connect the optimum charge rate for the device connected.The charge port supports a maximum of 2.1 Amp charge current for devices.The USB charge port will shutdown and protect the GMA for current draw above2.3 Amps.Table 1-4 Speaker OutputAircraft Voltage Speaker Impedance Output Power14V 4 Ω 3 Watts8 Ω Not Recommended28V 4 Ω 10 Watts8 Ω 7 WattsTable 1-3 Electrical CharacteristicsCharacteristic Specification
