AMB2050NR KIT2 - Class D 2x50W Bluetooth amplifier with power supply and volume control


The AMB2050NR KIT2 kit consists of a Class D AMB2050NR Amplifier based on the TPA3116D2 chip with integrated bluetooth module and VCB0M01 plug and play volume control, complete, a 24V 6A ALC24V6AJ switching power supply and a CVAIT307515 power cable.

The output power of the class D amplifier is 50W with a supply voltage of 24V. The supported voltage range varies from a minimum of 10V to 24V. Passive loudspeaker drivers varying from a nominal impedance of 4 to 8 ohms.

The sources used, in order to send musical signal to the class D amplifier, can be connected via cable (RCA) or by means of Bluetooth 4.0 protocol, selectable via micro-switch on the board.

Finally, the AMB2050NR amplifier has a VCB (Volume Control Board) port that allows communication and connection (plug & play) between an external digital volume control (present in the kit) and the class D amplifier.
