Class D 2x50W Bluetooth Amplifier with Volume Control, 24V Power Supply and Power Cable |
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.
Attention: the VCB0M01 volume control is supplied with 3 wires. For this kit, use only the 5-pin cable to connect the volume control to the amplifier as shown above.
