Class D 2x15W Amplifier - Bluetooth 4.0 with Volume Control and power supply |
This kit is designed for factory or do-it-yourself users. This kit includes a volume knob, a weatherproof panel mount LED, power supply and a AMB2015NK amplifier board. People can adjust the volume of the Bluetooth audio on the smartphone or by turning the knob. It is possible to supply this kit with a 15VDC power supply or a 12 V battery. The LED can indicate the ON / OFF status and the battery voltage status. The user can install this kit in a box and easily create his own audio amplifier.
AMB2015NK is a 2x15W class D audio amplifier card with integrated Bluetooth 4.0. It has a perfect class D architecture (based on TPA3110D2) and each channel has a power of 15W if powered by 15V. This board can be powered by any DC8V-16V 30W power supply. It can be used to drive passive 4 or 8Ω speakers. The Bluetooth audio volume control circuit is also integrated on this card. Turn the knob clockwise to increase the volume. Turn the knob counterclockwise to decrease the volume. Click the knob to turn on / off the amplifier.
It perfect for your Hi-Fi application. You may want to associate a mobile phone or computer (etc.), use the phone or PC (etc.) or to search for a new Bluetooth device. The module will appear as "BT Speaker" (you can also change the BT name if you have a programmer). You dont need a PIN, match it and then you can listen to music.
