XH-M314 TPA3118 Bluetooth Digital Power Amplifier Board 2 x 30W Stereo With the XH-M314 TPA3118 module, two speakers without regular Bluetooth function can be connected via Bluetooth. The module also serves as a digital amplifier, which provides better sound quality. As a digital amplifier, it has a higher overload capability than an analog amplifier and does not cause crossover distortion or transient intermodulation distortion. The output is a two-channel, 30W each. The voltage input has an input voltage range of 8 to 26 V DC. Audio input is either via Bluetooth or via the 3.5 mm audio jack (using a jack plug). Overview: Chip type: TPA3118 Chip protection: over voltage / under voltage / over temperature / DC detection / short circuit Supply voltage: 8V ~ 26 V DC Audio input: 3.5 mm jack (jack socket) and Bluetooth Output power: 2x 30 W Channel: Dual channel output Output impedance: 4 ~ 8 ohm speaker Powerful subwoofer, good sound quality, no distortion Dimensions: 72 * 52.2 * 12.3 mm No Bluetooth password is required for the module. Once a device is paired, the module will not be visible to other devices.
